Practical Implementation

Practical Implementation

_(Click the image above to view video of this lesson)_

Practical implementation is where the power of the Model Context Protocol (MCP) becomes tangible.

While understanding the theory and architecture behind MCP is important, the real value emerges when you apply these concepts to build, test, and deploy solutions that solve real-world problems.

This chapter bridges the gap between conceptual knowledge and hands-on development, guiding you through the process of bringing MCP-based applications to life.

Whether you are developing intelligent assistants, integrating AI into business workflows, or building custom tools for data processing, MCP provides a flexible foundation.

Its language-agnostic design and official SDKs for popular programming languages make it accessible to a wide range of developers.

By leveraging these SDKs, you can quickly prototype, iterate, and scale your solutions across different platforms and environments.

In the following sections, you'll find practical examples, sample code, and deployment strategies that demonstrate how to implement MCP in C#, Java with Spring, TypeScript, JavaScript, and Python.

You'll also learn how to debug and test your MCP servers, manage APIs, and deploy solutions to the cloud using Azure.

These hands-on resources are designed to accelerate your learning and help you confidently build robust, production-ready MCP applications.

Overview

This lesson focuses on practical aspects of MCP implementation across multiple programming languages.

We'll explore how to use MCP SDKs in C#, Java with Spring, TypeScript, JavaScript, and Python to build robust applications, debug and test MCP servers, and create reusable resources, prompts, and tools.

Learning Objectives

By the end of this lesson, you will be able to:

  • Implement MCP solutions using official SDKs in various programming languages
  • Debug and test MCP servers systematically
  • Create and use server features (Resources, Prompts, and Tools)
  • Design effective MCP workflows for complex tasks
  • Optimize MCP implementations for performance and reliability
  • Official SDK Resources

    The Model Context Protocol offers official SDKs for multiple languages (aligned with MCP Specification 2025-11-25):

  • C# SDK
  • Java with Spring SDK Note: requires dependency on Project Reactor. (See discussion issue 246.)
  • TypeScript SDK
  • Python SDK
  • Kotlin SDK
  • Go SDK
  • Working with MCP SDKs

    This section provides practical examples of implementing MCP across multiple programming languages.

    You can find sample code in the samples directory organized by language.

    Available Samples

    The repository includes sample implementations in the following languages:

  • C#

    Sample

    The previous example shows how to use a local .NET project with the stdio type.

    And how to run the server locally in a container.

    This is a good solution in many situations.

    However, it can be useful to have the server running remotely, like in a cloud environment.

    This is where the http type comes in.

    Looking at the solution in the 04-PracticalImplementation folder, it may look much more complex than the previous one.

    But in reality, it is not.

    If you look closely to the project src/Calculator, you will see that it is mostly the same code as the previous example.

    The only difference is that we are using a different library ModelContextProtocol.AspNetCore to handle the HTTP requests.

    And we change the method IsPrime to make it private, just to show that you can have private methods in your code.

    The rest of the code is the same as before.

    The other projects are from .NET Aspire.

    Having .NET Aspire in the solution will improve the experience of the developer while developing and testing and help with observability.

    It is not required to run the server, but it is a good practice to have it in your solution.

    Start the server locally

    1. From VS Code (with the C# DevKit extension), navigate down to the 04-PracticalImplementation/samples/csharp directory.

    1. Execute the following command to start the server:

    ```bash

    dotnet watch run --project ./src/AppHost

    ```

    1.

    When a web browser opens the .NET Aspire dashboard, note the http URL.

    It should be something like http://localhost:5058/.

    !.NET Aspire Dashboard

    Test Streamable HTTP with the MCP Inspector

    If you have Node.js 22.7.5 and higher, you can use the MCP Inspector to test your server.

    Start the server and run the following command in a terminal:

    
    npx @modelcontextprotocol/inspector http://localhost:5058
    
    
  • Select the Streamable HTTP as the Transport type.
  • In the Url field, enter the URL of the server noted earlier, and append /mcp. It should be http (not https) something like http://localhost:5058/mcp.
  • select the Connect button.
  • A nice thing about the Inspector is that it provide a nice visibility on what is happening.

  • Try listing the available tools
  • Try some of them, it should works just like before.
  • Test MCP Server with GitHub Copilot Chat in VS Code

    To use the Streamable HTTP transport with GitHub Copilot Chat, change the configuration of the calc-mcp server created previously to look like this:

    
    // .vscode/mcp.json
    
    {
    
      "servers": {
    
        "calc-mcp": {
    
          "type": "http",
    
          "url": "http://localhost:5058/mcp"
    
        }
    
      }
    
    }
    
    

    Do some tests:

  • Ask for "3 prime numbers after 6780". Note how Copilot will use the new tools NextFivePrimeNumbers and only return the first 3 prime numbers.
  • Ask for "7 prime numbers after 111", to see what happens.
  • Ask for "John has 24 lollies and wants to distribute them all to his 3 kids. How many lollies does each kid have?", to see what happens.
  • Deploy the server to Azure

    Let's deploy the server to Azure so more people can use it.

    From a terminal, navigate to the folder 04-PracticalImplementation/samples/csharp and run the following command:

    
    azd up
    
    

    Once the deployment is over, you should see a message like this:

    Grab the URL and use it in the MCP Inspector and in the GitHub Copilot Chat.

    
    // .vscode/mcp.json
    
    {
    
      "servers": {
    
        "calc-mcp": {
    
          "type": "http",
    
          "url": "https://calc-mcp.gentleriver-3977fbcf.australiaeast.azurecontainerapps.io/mcp"
    
        }
    
      }
    
    }
    
    

    What's next?

    We try different transport types and testing tools.

    We also deploy your MCP server to Azure.

    But what if our server needs to access to private resources?

    For example, a database or a private API?

    In the next chapter, we will see how we can improve the security of our server.

    System Architecture

    This project demonstrates a web application that uses content safety checking before passing user prompts to a calculator service via Model Context Protocol (MCP).

    How It Works

    1. User Input: The user enters a calculation prompt in the web interface

    2. Content Safety Screening (Input): The prompt is analyzed by Azure Content Safety API

    3. Safety Decision (Input):

    - If the content is safe (severity < 2 in all categories), it proceeds to the calculator

    - If the content is flagged as potentially harmful, the process stops and returns a warning

    4. Calculator Integration: Safe content is processed by LangChain4j, which communicates with the MCP calculator server

    5. Content Safety Screening (Output): The bot's response is analyzed by Azure Content Safety API

    6. Safety Decision (Output):

    - If the bot response is safe, it's shown to the user

    - If the bot response is flagged as potentially harmful, it's replaced with a warning

    7. Response: Results (if safe) are displayed to the user along with both safety analyses

    Using Model Context Protocol (MCP) with Calculator Services

    This project demonstrates how to use Model Context Protocol (MCP) to call calculator MCP services from LangChain4j. The implementation uses a local MCP server running on port 8080 to provide calculator operations.

    Setting up Azure Content Safety Service

    Before using the content safety features, you need to create an Azure Content Safety service resource:

    1. Sign in to the Azure Portal

    2. Click "Create a resource" and search for "Content Safety"

    3. Select "Content Safety" and click "Create"

    4. Enter a unique name for your resource

    5. Select your subscription and resource group (or create a new one)

    6. Choose a supported region (check Region availability for details)

    7. Select an appropriate pricing tier

    8. Click "Create" to deploy the resource

    9. Once deployment is complete, click "Go to resource"

    10. In the left pane, under "Resource Management", select "Keys and Endpoint"

    11. Copy either of the keys and the endpoint URL for use in the next step

    Configuring Environment Variables

    Set the GITHUB_TOKEN environment variable for GitHub models authentication:

    
    export GITHUB_TOKEN=<your_github_token>
    
    

    For content safety features, set:

    
    export CONTENT_SAFETY_ENDPOINT=<your_content_safety_endpoint>
    
    export CONTENT_SAFETY_KEY=<your_content_safety_key>
    
    

    These environment variables are used by the application to authenticate with the Azure Content Safety service.

    If these variables are not set, the application will use placeholder values for demonstration purposes, but the content safety features will not work properly.

    Starting the Calculator MCP Server

    Before running the client, you need to start the calculator MCP server in SSE mode on localhost:8080.

    Project Description

    This project demonstrates the integration of Model Context Protocol (MCP) with LangChain4j to call calculator services. Key features include:

  • Using MCP to connect to a calculator service for basic math operations
  • Dual-layer content safety checking on both user prompts and bot responses
  • Integration with GitHub's gpt-4.1-nano model via LangChain4j
  • Using Server-Sent Events (SSE) for MCP transport
  • Content Safety Integration

    The project includes comprehensive content safety features to ensure that both user inputs and system responses are free from harmful content:

    1. Input Screening: All user prompts are analyzed for harmful content categories such as hate speech, violence, self-harm, and sexual content before processing.

    2. Output Screening: Even when using potentially uncensored models, the system checks all generated responses through the same content safety filters before displaying them to the user.

    This dual-layer approach ensures that the system remains safe regardless of which AI model is being used, protecting users from both harmful inputs and potentially problematic AI-generated outputs.

    Web Client

    The application includes a user-friendly web interface that allows users to interact with the Content Safety Calculator system:

    Web Interface Features

  • Simple, intuitive form for entering calculation prompts
  • Dual-layer content safety validation (input and output)
  • Real-time feedback on prompt and response safety
  • Color-coded safety indicators for easy interpretation
  • Clean, responsive design that works on various devices
  • Example safe prompts to guide users
  • Using the Web Client

    1. Start the application:

    ```sh

    mvn spring-boot:run

    ```

    2. Open your browser and navigate to http://localhost:8087

    3. Enter a calculation prompt in the provided text area (e.g., "Calculate the sum of 24.5 and 17.3")

    4. Click "Submit" to process your request

    5. View the results, which will include:

    - Content safety analysis of your prompt

    - The calculated result (if prompt was safe)

    - Content safety analysis of the bot's response

    - Any safety warnings if either the input or output was flagged

    The web client automatically handles both content safety verification processes, ensuring all interactions are safe and appropriate regardless of which AI model is being used.

    Model Context Protocol (MCP) Python Implementation

    This repository contains a Python implementation of the Model Context Protocol (MCP), demonstrating how to create both a server and client application that communicate using the MCP standard.

    Overview

    The MCP implementation consists of two main components:

    1. MCP Server (server.py) - A server that exposes:

    - Tools: Functions that can be called remotely

    - Resources: Data that can be retrieved

    - Prompts: Templates for generating prompts for language models

    2. MCP Client (client.py) - A client application that connects to the server and uses its features

    Features

    This implementation demonstrates several key MCP features:

    Tools

  • completion - Generates text completions from AI models (simulated)
  • add - Simple calculator that adds two numbers
  • Resources

  • models:// - Returns information about available AI models
  • greeting://{name} - Returns a personalized greeting for a given name
  • Prompts

  • review_code - Generates a prompt for reviewing code
  • Installation

    To use this MCP implementation, install the required packages:

    
    pip install mcp-server mcp-client
    
    

    Running the Server and Client

    Starting the Server

    Run the server in one terminal window:

    
    python server.py
    
    

    The server can also be run in development mode using the MCP CLI:

    
    mcp dev server.py
    
    

    Or installed in Claude Desktop (if available):

    
    mcp install server.py
    
    

    Running the Client

    Run the client in another terminal window:

    
    python client.py
    
    

    This will connect to the server and demonstrate all available features.

    Client Usage

    The client (client.py) demonstrates all the MCP capabilities:

    
    python client.py
    
    

    This will connect to the server and exercise all features including tools, resources, and prompts. The output will show:

    1. Calculator tool result (5 + 7 = 12)

    2. Completion tool response to "What is the meaning of life?"

    3. List of available AI models

    4. Personalized greeting for "MCP Explorer"

    5. Code review prompt template

    Implementation Details

    The server is implemented using the FastMCP API, which provides high-level abstractions for defining MCP services.

    Here's a simplified example of how tools are defined:

    
    @mcp.tool()
    
    def add(a: int, b: int) -> int:
    
        """Add two numbers together
    
        
    
        Args:
    
            a: First number
    
            b: Second number
    
        
    
        Returns:
    
            The sum of the two numbers
    
        """
    
        logger.info(f"Adding {a} and {b}")
    
        return a + b
    
    

    The client uses the MCP client library to connect to and call the server:

    
    async with stdio_client(server_params) as (reader, writer):
    
        async with ClientSession(reader, writer) as session:
    
            await session.initialize()
    
            result = await session.call_tool("add", arguments={"a": 5, "b": 7})

    Practical Guides

    Additional guides for practical MCP implementation:

  • Pagination and Large Result Sets

    Pagination and Large Result Sets in MCP

    When your MCP server handles large datasets - whether listing thousands of files, database records, or search results - you need pagination to manage memory efficiently and provide responsive user experiences.

    This guide covers how to implement and use pagination in MCP.

    Why Pagination Matters

    Without pagination, large responses can cause:

  • Memory exhaustion - Loading millions of records at once
  • Slow response times - Users wait while all data loads
  • Timeout errors - Requests exceed timeout limits
  • Poor AI performance - LLMs struggle with massive context
  • MCP uses cursor-based pagination for reliable, consistent paging through result sets.

    ---

    How MCP Pagination Works

    The Cursor Concept

    A cursor is an opaque string that marks your position in a result set. Think of it like a bookmark in a long book.

    
    sequenceDiagram
    
        participant Client
    
        participant Server
    
        
    
        Client->>Server: tools/list (no cursor)
    
        Server-->>Client: tools [1-10], nextCursor: "abc123"
    
        
    
        Client->>Server: tools/list (cursor: "abc123")
    
        Server-->>Client: tools [11-20], nextCursor: "def456"
    
        
    
        Client->>Server: tools/list (cursor: "def456")
    
        Server-->>Client: tools [21-25], nextCursor: null (end)
    
    

    Pagination in MCP Methods

    These MCP methods support pagination:

    Method Returns Cursor Support -------- --------- ---------------- tools/list Tool definitions ✅ resources/list Resource definitions ✅ prompts/list Prompt definitions ✅ resources/templates/list Resource templates ✅

    Client Implementation

    Python Client

    
    from mcp import ClientSession
    
    
    
    async def get_all_tools(session: ClientSession) -> list:
    
        """Fetch all tools using pagination."""
    
        all_tools = []
    
        cursor = None
    
        
    
        while True:
    
            result = await session.list_tools(cursor=cursor)
    
            all_tools.extend(result.tools)
    
            
    
            if result.nextCursor is None:
    
                break
    
            cursor = result.nextCursor
    
        
    
        return all_tools
    
    
    
    # Usage
    
    async with client_session as session:
    
        tools = await get_all_tools(session)
    
        print(f"Found {len(tools)} tools")
    
    

    TypeScript Client

    
    import { Client } from "@modelcontextprotocol/sdk/client/index.js";
    
    
    
    async function getAllTools(client: Client): Promise<Tool[]> {
    
      const allTools: Tool[] = [];
    
      let cursor: string | undefined = undefined;
    
      
    
      do {
    
        const result = await client.listTools({ cursor });
    
        allTools.push(...result.tools);
    
        cursor = result.nextCursor;
    
      } while (cursor);
    
      
    
      return allTools;

    // Usage
    
    const tools = await getAllTools(client);
    
    console.log(`Found ${tools.length} tools`);
    
    

    Lazy Loading Pattern

    For very large datasets, load pages on-demand:

    
    class PaginatedToolIterator:
    
        """Lazily iterate through paginated tools."""
    
        
    
        def __init__(self, session: ClientSession):
    
            self.session = session
    
            self.cursor = None
    
            self.buffer = []
    
            self.exhausted = False
    
        
    
        async def __anext__(self):
    
            # Return from buffer if available
    
            if self.buffer:
    
                return self.buffer.pop(0)
    
            
    
            # Check if we've exhausted all pages
    
            if self.exhausted:
    
                raise StopAsyncIteration
    
            
    
            # Fetch next page
    
            result = await self.session.list_tools(cursor=self.cursor)
    
            self.buffer = list(result.tools)
    
            self.cursor = result.nextCursor
    
            
    
            if self.cursor is None:
    
                self.exhausted = True
    
            
    
            if not self.buffer:
    
                raise StopAsyncIteration

    # Usage - memory efficient for large datasets
    
    async for tool in PaginatedToolIterator(session):
    
        process_tool(tool)

    Pagination for Resources

    Resources often need pagination for directories or large datasets:

    
    from mcp.server import Server
    
    from mcp.types import Resource, ListResourcesResult
    
    import os
    
    
    
    app = Server("file-server")
    
    
    
    @app.list_resources()
    
    async def list_resources(cursor: str | None = None) -> ListResourcesResult:
    
        """List files in directory with pagination."""
    
        
    
        directory = "/data/files"
    
        all_files = sorted(os.listdir(directory))
    
        
    
        # Decode cursor (file index)
    
        start_index = int(cursor) if cursor else 0
    
        page_size = 20
    
        end_index = min(start_index + page_size, len(all_files))
    
        
    
        # Create resource list for this page
    
        resources = []
    
        for filename in all_files[start_index:end_index]:
    
            filepath = os.path.join(directory, filename)
    
            resources.append(Resource(
    
                uri=f"file://{filepath}",
    
                name=filename,
    
                mimeType="application/octet-stream"
    
            ))
    
        
    
        # Calculate next cursor
    
        next_cursor = str(end_index) if end_index < len(all_files) else None
    
        
    
        return ListResourcesResult(
    
            resources=resources,
    
            nextCursor=next_cursor
    
        )
    
    

    ---

    Cursor Design Strategies

    Strategy 1: Index-Based (Simple)

    
    # Cursor is just the index
    
    cursor = "50"  # Start at item 50
    
    

    Pros: Simple, stateless

    Cons: Results can shift if items are added/removed

    Strategy 2: ID-Based (Stable)

    
    # Cursor is the last seen ID
    
    cursor = "item_abc123"  # Start after this item
    
    

    Pros: Stable even if items change

    Cons: Requires ordered IDs

    Strategy 3: Encoded State (Complex)

    
    import base64
    
    import json
    
    
    
    def encode_cursor(state: dict) -> str:
    
        return base64.b64encode(json.dumps(state).encode()).decode()
    
    
    
    def decode_cursor(cursor: str) -> dict:
    
        return json.loads(base64.b64decode(cursor).decode())
    
    
    
    # Cursor contains multiple state fields
    
    cursor = encode_cursor({
    
        "offset": 50,
    
        "filter": "active",
    
        "sort": "name"
    
    })
    
    

    Pros: Can encode complex state

    Cons: More complex, larger cursor strings

    ---

    Best Practices

    1. Choose Appropriate Page Sizes

    
    # Consider the data size
    
    PAGE_SIZE_SMALL_ITEMS = 100   # Simple metadata
    
    PAGE_SIZE_MEDIUM_ITEMS = 20   # Richer objects
    
    PAGE_SIZE_LARGE_ITEMS = 5     # Complex content
    
    

    2. Handle Invalid Cursors Gracefully

    
    @app.list_tools()
    
    async def list_tools(cursor: str | None = None) -> ListToolsResult:
    
        try:
    
            start_index = int(cursor) if cursor else 0
    
            if start_index < 0 or start_index >= len(ALL_TOOLS):
    
                start_index = 0  # Reset to beginning
    
        except (ValueError, TypeError):
    
            start_index = 0  # Invalid cursor, start fresh
    
        # ...
    
    

    3. Include Total Count (Optional)

    
    return ListToolsResult(
    
        tools=page_tools,
    
        nextCursor=next_cursor,
    
        # Some implementations include total for UI progress
    
        _meta={"total": len(ALL_TOOLS)}
    
    )
    
    

    4. Test Edge Cases

    
    async def test_pagination():
    
        # Empty result set
    
        result = await session.list_tools()
    
        assert result.tools == []
    
        assert result.nextCursor is None
    
        
    
        # Single page
    
        result = await session.list_tools()
    
        assert len(result.tools) <= PAGE_SIZE
    
        
    
        # Invalid cursor
    
        result = await session.list_tools(cursor="invalid")
    
        assert result.tools  # Should return first page
    
    

    ---

    Common Pitfalls

    ❌ Returning All Results Then Paginating Client-Side

    
    # BAD: Loads everything into memory
    
    @app.list_tools()
    
    async def list_tools() -> ListToolsResult:
    
        all_tools = load_all_tools()  # 1 million tools!
    
        return ListToolsResult(tools=all_tools)
    
    

    ✅ Paginate at the Data Source

    
    # GOOD: Only loads what's needed
    
    @app.list_tools()
    
    async def list_tools(cursor: str | None = None) -> ListToolsResult:
    
        offset = int(cursor) if cursor else 0
    
        tools = await db.query_tools(offset=offset, limit=PAGE_SIZE)
    
        return ListToolsResult(tools=tools, nextCursor=...)

    System Architecture

    This project demonstrates a web application that uses content safety checking before passing user prompts to a calculator service via Model Context Protocol (MCP).

    How It Works

    1. User Input: The user enters a calculation prompt in the web interface

    2. Content Safety Screening (Input): The prompt is analyzed by Azure Content Safety API

    3. Safety Decision (Input):

    - If the content is safe (severity < 2 in all categories), it proceeds to the calculator

    - If the content is flagged as potentially harmful, the process stops and returns a warning

    4. Calculator Integration: Safe content is processed by LangChain4j, which communicates with the MCP calculator server

    5. Content Safety Screening (Output): The bot's response is analyzed by Azure Content Safety API

    6. Safety Decision (Output):

    - If the bot response is safe, it's shown to the user

    - If the bot response is flagged as potentially harmful, it's replaced with a warning

    7. Response: Results (if safe) are displayed to the user along with both safety analyses

    Using Model Context Protocol (MCP) with Calculator Services

    This project demonstrates how to use Model Context Protocol (MCP) to call calculator MCP services from LangChain4j. The implementation uses a local MCP server running on port 8080 to provide calculator operations.

    Setting up Azure Content Safety Service

    Before using the content safety features, you need to create an Azure Content Safety service resource:

    1. Sign in to the Azure Portal

    2. Click "Create a resource" and search for "Content Safety"

    3. Select "Content Safety" and click "Create"

    4. Enter a unique name for your resource

    5. Select your subscription and resource group (or create a new one)

    6. Choose a supported region (check Region availability for details)

    7. Select an appropriate pricing tier

    8. Click "Create" to deploy the resource

    9. Once deployment is complete, click "Go to resource"

    10. In the left pane, under "Resource Management", select "Keys and Endpoint"

    11. Copy either of the keys and the endpoint URL for use in the next step

    Configuring Environment Variables

    Set the GITHUB_TOKEN environment variable for GitHub models authentication:

    
    export GITHUB_TOKEN=<your_github_token>
    
    

    For content safety features, set:

    
    export CONTENT_SAFETY_ENDPOINT=<your_content_safety_endpoint>
    
    export CONTENT_SAFETY_KEY=<your_content_safety_key>
    
    

    These environment variables are used by the application to authenticate with the Azure Content Safety service.

    If these variables are not set, the application will use placeholder values for demonstration purposes, but the content safety features will not work properly.

    Starting the Calculator MCP Server

    Before running the client, you need to start the calculator MCP server in SSE mode on localhost:8080.

    Project Description

    This project demonstrates the integration of Model Context Protocol (MCP) with LangChain4j to call calculator services. Key features include:

  • Using MCP to connect to a calculator service for basic math operations
  • Dual-layer content safety checking on both user prompts and bot responses
  • Integration with GitHub's gpt-4.1-nano model via LangChain4j
  • Using Server-Sent Events (SSE) for MCP transport
  • Content Safety Integration

    The project includes comprehensive content safety features to ensure that both user inputs and system responses are free from harmful content:

    1. Input Screening: All user prompts are analyzed for harmful content categories such as hate speech, violence, self-harm, and sexual content before processing.

    2. Output Screening: Even when using potentially uncensored models, the system checks all generated responses through the same content safety filters before displaying them to the user.

    This dual-layer approach ensures that the system remains safe regardless of which AI model is being used, protecting users from both harmful inputs and potentially problematic AI-generated outputs.

    Web Client

    The application includes a user-friendly web interface that allows users to interact with the Content Safety Calculator system:

    Web Interface Features

  • Simple, intuitive form for entering calculation prompts
  • Dual-layer content safety validation (input and output)
  • Real-time feedback on prompt and response safety
  • Color-coded safety indicators for easy interpretation
  • Clean, responsive design that works on various devices
  • Example safe prompts to guide users
  • Using the Web Client

    1. Start the application:

    ```sh

    mvn spring-boot:run

    ```

    2. Open your browser and navigate to http://localhost:8087

    3. Enter a calculation prompt in the provided text area (e.g., "Calculate the sum of 24.5 and 17.3")

    4. Click "Submit" to process your request

    5. View the results, which will include:

    - Content safety analysis of your prompt

    - The calculated result (if prompt was safe)

    - Content safety analysis of the bot's response

    - Any safety warnings if either the input or output was flagged

    The web client automatically handles both content safety verification processes, ensuring all interactions are safe and appropriate regardless of which AI model is being used.

    Here's an example of a tool registration where we register a tool that makes a mock call to an LLM:

    
    this.mcpServer.tool(
    
        'completion',
    
        {
    
        model: z.string(),
    
        prompt: z.string(),
    
        options: z.object({
    
            temperature: z.number().optional(),
    
            max_tokens: z.number().optional(),
    
            stream: z.boolean().optional()
    
        }).optional()
    
        },
    
        async ({ model, prompt, options }) => {
    
        console.log(`Processing completion request for model: ${model}`);
    
        
    
        // Validate model
    
        if (!this.models.includes(model)) {
    
            throw new Error(`Model ${model} not supported`);
    
        }
    
        
    
        // Emit event for monitoring/metrics
    
        this.events.emit('request', { 
    
            type: 'completion', 
    
            model, 
    
            timestamp: new Date() 
    
        });
    
        
    
        // In a real implementation, this would call an AI model
    
        // Here we just echo back parts of the request with a mock response
    
        const response = {
    
            id: `mcp-resp-${Date.now()}`,
    
            model,
    
            text: `This is a response to: ${prompt.substring(0, 30)}...`,
    
            usage: {
    
            promptTokens: prompt.split(' ').length,
    
            completionTokens: 20,
    
            totalTokens: prompt.split(' ').length + 20
    
            }
    
        };
    
        
    
        // Simulate network delay
    
        await new Promise(resolve => setTimeout(resolve, 500));
    
        
    
        // Emit completion event
    
        this.events.emit('completion', {
    
            model,
    
            timestamp: new Date()
    
        });
    
        
    
        return {
    
            content: [
    
            {
    
                type: 'text',
    
                text: JSON.stringify(response)
    
            }

    Sample implementation: Python Implementation

    The Python SDK offers a Pythonic approach to MCP implementation with excellent ML framework integrations.

    Key Features

  • Async/await support with asyncio
  • FastAPI integration``
  • Simple tool registration
  • Native integration with popular ML libraries
  • For a complete Python implementation sample, see Python sample

    Model Context Protocol (MCP) Python Implementation

    This repository contains a Python implementation of the Model Context Protocol (MCP), demonstrating how to create both a server and client application that communicate using the MCP standard.

    Overview

    The MCP implementation consists of two main components:

    1. MCP Server (server.py) - A server that exposes:

    - Tools: Functions that can be called remotely

    - Resources: Data that can be retrieved

    - Prompts: Templates for generating prompts for language models

    2. MCP Client (client.py) - A client application that connects to the server and uses its features

    Features

    This implementation demonstrates several key MCP features:

    Tools

  • completion - Generates text completions from AI models (simulated)
  • add - Simple calculator that adds two numbers
  • Resources

  • models:// - Returns information about available AI models
  • greeting://{name} - Returns a personalized greeting for a given name
  • Prompts

  • review_code - Generates a prompt for reviewing code
  • Installation

    To use this MCP implementation, install the required packages:

    
    pip install mcp-server mcp-client
    
    

    Running the Server and Client

    Starting the Server

    Run the server in one terminal window:

    
    python server.py
    
    

    The server can also be run in development mode using the MCP CLI:

    
    mcp dev server.py
    
    

    Or installed in Claude Desktop (if available):

    
    mcp install server.py
    
    

    Running the Client

    Run the client in another terminal window:

    
    python client.py
    
    

    This will connect to the server and demonstrate all available features.

    Client Usage

    The client (client.py) demonstrates all the MCP capabilities:

    
    python client.py
    
    

    This will connect to the server and exercise all features including tools, resources, and prompts. The output will show:

    1. Calculator tool result (5 + 7 = 12)

    2. Completion tool response to "What is the meaning of life?"

    3. List of available AI models

    4. Personalized greeting for "MCP Explorer"

    5. Code review prompt template

    Implementation Details

    The server is implemented using the FastMCP API, which provides high-level abstractions for defining MCP services.

    Here's a simplified example of how tools are defined:

    
    @mcp.tool()
    
    def add(a: int, b: int) -> int:
    
        """Add two numbers together
    
        
    
        Args:
    
            a: First number
    
            b: Second number
    
        
    
        Returns:
    
            The sum of the two numbers
    
        """
    
        logger.info(f"Adding {a} and {b}")
    
        return a + b
    
    

    The client uses the MCP client library to connect to and call the server:

    
    async with stdio_client(server_params) as (reader, writer):
    
        async with ClientSession(reader, writer) as session:
    
            await session.initialize()
    
            result = await session.call_tool("add", arguments={"a": 5, "b": 7})

    API management

    Azure API Management is a great answer to how we can secure MCP Servers. The idea is to put an Azure API Management instance in front of your MCP Server and let it handle features you're likely to want like:

  • rate limiting
  • token management
  • monitoring
  • load balancing
  • security
  • Azure Sample

    Here's an Azure Sample doing exactly that, i.e creating an MCP Server and securing it with Azure API Management.

    See how the authorization flow happens in below image:

    In the preceding image, the following takes place:

  • Authentication/Authorization takes place using Microsoft Entra.
  • Azure API Management acts as a gateway and uses policies to direct and manage traffic.
  • Azure Monitor logs all request for further analysis.
  • Authorization flow

    Let's have a look at the authorization flow more in detail:

    MCP authorization specification

    Learn more about the MCP Authorization specification

    Deploy Remote MCP Server to Azure

    Let's see if we can deploy the sample we mentioned earlier:

    1. Clone the repo

    ```bash

    git clone https://github.com/Azure-Samples/remote-mcp-apim-functions-python.git

    cd remote-mcp-apim-functions-python

    ```

    1. Register Microsoft.App resource provider.

    - If you are using Azure CLI, run az provider register --namespace Microsoft.App --wait.

    - If you are using Azure PowerShell, run Register-AzResourceProvider -ProviderNamespace Microsoft.App.

    Then run (Get-AzResourceProvider -ProviderNamespace Microsoft.App).RegistrationState after some time to check if the registration is complete.

    1. Run this azd command to provision the api management service, function app(with code) and all other required Azure resources

    ```shell

    azd up

    ```

    This commands should deploy all the cloud resources on Azure

    Testing your server with MCP Inspector

    1. In a new terminal window, install and run MCP Inspector

    ```shell

    npx @modelcontextprotocol/inspector

    ```

    You should see an interface similar to:

    !Connect to Node inspector

    1. CTRL click to load the MCP Inspector web app from the URL displayed by the app (e.g. http://127.0.0.1:6274/#resources)

    1. Set the transport type to SSE

    1. Set the URL to your running API Management SSE endpoint displayed after azd up and Connect:

    ```shell

    https://.azure-api.net/mcp/sse

    ```

    1. List Tools. Click on a tool and Run Tool.

    If all the steps have worked, you should now be connected to the MCP server and you've been able to call a tool.

    MCP servers for Azure

    The Samples provides a complete solution that allows developers to:

  • Build and run locally: Develop and debug a MCP server on a local machine
  • Deploy to Azure: Easily deploy to the cloud with a simple azd up command
  • Connect from clients: Connect to the MCP server from various clients including VS Code's Copilot agent mode and the MCP Inspector tool
  • Key Features

  • Authentication options: Supports OAuth using built-in auth and/or API Management
  • Network isolation: Allows network isolation using Azure Virtual Networks (VNET)
  • Serverless architecture: Leverages Azure Functions for scalable, event-driven execution
  • Local development: Comprehensive local development and debugging support
  • Simple deployment: Streamlined deployment process to Azure
  • The repository includes all necessary configuration files, source code, and infrastructure definitions to quickly get started with a production-ready MCP server implementation.

  • Azure Remote MCP Functions Python - Sample implementation of MCP using Azure Functions with Python
  • Azure Remote MCP Functions .NET - Sample implementation of MCP using Azure Functions with C# .NET
  • Azure Remote MCP Functions Node/Typescript - Sample implementation of MCP using Azure Functions with Node/TypeScript.
  • Key Takeaways

  • MCP SDKs provide language-specific tools for implementing robust MCP solutions
  • The debugging and testing process is critical for reliable MCP applications
  • Reusable prompt templates enable consistent AI interactions
  • Well-designed workflows can orchestrate complex tasks using multiple tools
  • Implementing MCP solutions requires consideration of security, performance, and error handling

    C# Implementation

    In this code snippet, we demonstrate how to integrate MCP with Azure OpenAI using the Azure OpenAI SDK.

    
    // .NET Azure OpenAI Integration
    
    using Microsoft.Mcp.Client;
    
    using Azure.AI.OpenAI;
    
    using Microsoft.Extensions.Configuration;
    
    using System.Threading.Tasks;
    
    
    
    namespace EnterpriseIntegration
    
    {
    
        public class AzureOpenAiMcpClient
    
        {
    
            private readonly string _endpoint;
    
            private readonly string _apiKey;
    
            private readonly string _deploymentName;
    
            
    
            public AzureOpenAiMcpClient(IConfiguration config)
    
            {
    
                _endpoint = config["AzureOpenAI:Endpoint"];
    
                _apiKey = config["AzureOpenAI:ApiKey"];
    
                _deploymentName = config["AzureOpenAI:DeploymentName"];
    
            }
    
            
    
            public async Task<string> GetCompletionWithToolsAsync(string prompt, params string[] allowedTools)
    
            {
    
                // Create OpenAI client
    
                var client = new OpenAIClient(new Uri(_endpoint), new AzureKeyCredential(_apiKey));
    
                
    
                // Create completion options with tools
    
                var completionOptions = new ChatCompletionsOptions
    
                {
    
                    DeploymentName = _deploymentName,
    
                    Messages = { new ChatMessage(ChatRole.User, prompt) },
    
                    Temperature = 0.7f,
    
                    MaxTokens = 800
    
                };
    
                
    
                // Add tool definitions
    
                foreach (var tool in allowedTools)
    
                {
    
                    completionOptions.Tools.Add(new ChatCompletionsFunctionToolDefinition
    
                    {
    
                        Name = tool,
    
                        // In a real implementation, you'd add the tool schema here
    
                    });
    
                }
    
                
    
                // Get completion response
    
                var response = await client.GetChatCompletionsAsync(completionOptions);
    
                
    
                // Handle tool calls in the response
    
                foreach (var toolCall in response.Value.Choices[0].Message.ToolCalls)
    
                {
    
                    // Implementation to handle Azure OpenAI tool calls with MCP
    
                    // ...
    
                }
    
                
    
                return response.Value.Choices[0].Message.Content;
    
            }
    
        }
    
    }
    
    

    In the preceding code we've:

  • Configured the Azure OpenAI client with the endpoint, deployment name and API key.
  • Created a method GetCompletionWithToolsAsync to get completions with tool support.
  • Handled tool calls in the response.
  • You're encouraged to implement the actual tool handling logic based on your specific MCP server setup.

    Microsoft AI Foundry Integration

    Azure AI Foundry provides a platform for building and deploying AI agents. Integrating MCP with AI Foundry allows you to leverage its capabilities while maintaining the flexibility of MCP.

    In the below code, we develop an Agent integration that processes requests and handles tool calls using MCP.

    Java Implementation

    
    // Java AI Foundry Agent Integration
    
    package com.example.mcp.enterprise;
    
    
    
    import com.microsoft.aifoundry.AgentClient;
    
    import com.microsoft.aifoundry.AgentToolResponse;
    
    import com.microsoft.aifoundry.models.AgentRequest;
    
    import com.microsoft.aifoundry.models.AgentResponse;
    
    import com.mcp.client.McpClient;
    
    import com.mcp.tools.ToolRequest;
    
    import com.mcp.tools.ToolResponse;
    
    
    
    public class AIFoundryMcpBridge {
    
        private final AgentClient agentClient;
    
        private final McpClient mcpClient;
    
        
    
        public AIFoundryMcpBridge(String aiFoundryEndpoint, String mcpServerUrl) {
    
            this.agentClient = new AgentClient(aiFoundryEndpoint);
    
            this.mcpClient = new McpClient.Builder()
    
                .setServerUrl(mcpServerUrl)
    
                .build();
    
        }
    
        
    
        public AgentResponse processAgentRequest(AgentRequest request) {
    
            // Process the AI Foundry Agent request
    
            AgentResponse initialResponse = agentClient.processRequest(request);
    
            
    
            // Check if the agent requested to use tools
    
            if (initialResponse.getToolCalls() != null && !initialResponse.getToolCalls().isEmpty()) {
    
                // For each tool call, route it to the appropriate MCP tool
    
                for (AgentToolCall toolCall : initialResponse.getToolCalls()) {
    
                    String toolName = toolCall.getName();
    
                    Map<String, Object> parameters = toolCall.getArguments();
    
                    
    
                    // Execute the tool using MCP
    
                    ToolResponse mcpResponse = mcpClient.executeTool(toolName, parameters);
    
                    
    
                    // Create tool response for AI Foundry
    
                    AgentToolResponse toolResponse = new AgentToolResponse(
    
                        toolCall.getId(),
    
                        mcpResponse.getResult()
    
                    );
    
                    
    
                    // Submit tool response back to the agent
    
                    initialResponse = agentClient.submitToolResponse(
    
                        request.getConversationId(), 
    
                        toolResponse
    
                    );
    
                }
    
            }
    
            
    
            return initialResponse;
    
        }
    
    }
    
    

    In the preceding code, we've:

  • Created an AIFoundryMcpBridge class that integrates with both AI Foundry and MCP.
  • Implemented a method processAgentRequest that processes an AI Foundry agent request.
  • Handled tool calls by executing them through the MCP client and submitting the results back to the AI Foundry agent.
  • Integrating MCP with Azure ML

    Integrating MCP with Azure Machine Learning (ML) allows you to leverage Azure's powerful ML capabilities while maintaining the flexibility of MCP.

    This integration can be used to execute ML pipelines, register models as tools, and manage compute resources.

    In the preceding code, we've:

  • Created an EnterpriseAiIntegration class that integrates MCP with Azure ML.
  • Implemented an execute_ml_pipeline method that processes input data using MCP tools and submits an ML pipeline to Azure ML.
  • Implemented a register_ml_model_as_tool method that registers an Azure ML model as an MCP tool, including creating the necessary deployment environment and compute resources.
  • Mapped Azure ML data types to JSON schema types for tool registration.
  • Used asynchronous programming to handle potentially long-running operations like ML pipeline execution and model registration.

    Multi-Modal Integration

    Multi-modal applications are becoming increasingly important in AI, enabling richer interactions and more complex tasks.

    The Model Context Protocol (MCP) provides a framework for building multi-modal applications that can handle various types of data, such as text, images, and audio.

    MCP supports not just text-based interactions but also multi-modal capabilities, allowing models to work with images, audio, and other data types.

    Introduction

    In this lesson, you'll learn how to build a multi modal application.

    Learning Objectives

    By the end of this lesson, you will be able to:

  • Understand multi modal choices
  • Implement a multi modal app.
  • Architecture for Multi-Modal Support

    Multi-modal MCP implementations typically involve:

  • Modal-Specific Parsers: Components that convert different media types into formats the model can process.
  • Modal-Specific Tools: Special tools designed to handle specific modalities (image analysis, audio processing)
  • Unified Context Management: System to maintain context across different modalities
  • Response Generation: Capability to generate responses that may include multiple modalities.
  • Multi-Modal Example: Image Analysis

    In the below example, we will analyze an image and extract information.

            }
    
        }
    
    }
    
    

    In the preceding example, we've:

  • Created an ImageAnalysisTool that can analyze images using a hypothetical IImageAnalysisService.
  • Configured the MCP server to handle larger requests and support image content types.
  • Registered the image analysis tool with the server.
  • Implemented a method to download images from a URL and analyze them based on the requested type (objects, text, faces, etc.).
  • Returned structured results in a format compliant with the MCP specification.
  • Multi-Modal Example: Audio Processing

    Audio processing is another common modality in multi-modal applications. Below is an example of how to implement an audio transcription tool that can handle audio files and return transcriptions.

    In the preceding example, we've:

  • Created an AudioTranscriptionTool that can transcribe audio files.
  • Defined the tool's schema to accept either a URL or base64-encoded audio data.
  • Implemented the execute method to handle audio processing and transcription.
  • Configured the MCP server to handle multi-modal requests, including audio and image processing.
  • Registered the audio transcription tool with the server.
  • Implemented a method to download audio files from a URL or decode base64 audio data.
  • Used an AudioProcessor service to handle the actual transcription logic.
  • Started the MCP server to listen for requests.
  • Multi-Modal Example: Multi-Modal Response Generation

    MCP Root Contexts

    Root contexts are a fundamental concept in the Model Context Protocol that provide a persistent layer for maintaining conversation history and shared state across multiple requests and sessions.

    Introduction

    In this lesson, we will explore how to create, manage, and utilize root contexts in MCP.

    Learning Objectives

    By the end of this lesson, you will be able to:

  • Understand the purpose and structure of root contexts
  • Create and manage root contexts using MCP client libraries
  • Implement root contexts in .NET, Java, JavaScript, and Python applications
  • Utilize root contexts for multi-turn conversations and state management
  • Implement best practices for root context management
  • Understanding Root Contexts

    Root contexts serve as containers that hold the history and state for a series of related interactions. They enable:

  • Conversation Persistence: Maintaining coherent multi-turn conversations
  • Memory Management: Storing and retrieving information across interactions
  • State Management: Tracking progress in complex workflows
  • Context Sharing: Allowing multiple clients to access the same conversation state
  • In MCP, root contexts have these key characteristics:

  • Each root context has a unique identifier.
  • They can contain conversation history, user preferences, and other metadata.
  • They can be created, accessed, and archived as needed.
  • They support fine-grained access control and permissions.
  • Root Context Lifecycle

    Working with Root Contexts

    Here's an example of how to create and manage root contexts.

    C# Implementation

    
    // .NET Example: Root Context Management
    
    using Microsoft.Mcp.Client;
    
    using System;
    
    using System.Threading.Tasks;
    
    using System.Collections.Generic;
    
    
    
    public class RootContextExample
    
    {
    
        private readonly IMcpClient _client;
    
        private readonly IRootContextManager _contextManager;
    
        
    
        public RootContextExample(IMcpClient client, IRootContextManager contextManager)
    
        {
    
            _client = client;
    
            _contextManager = contextManager;
    
        }
    
        
    
        public async Task DemonstrateRootContextAsync()
    
        {
    
            // 1. Create a new root context
    
            var contextResult = await _contextManager.CreateRootContextAsync(new RootContextCreateOptions
    
            {
    
                Name = "Customer Support Session",
    
                Metadata = new Dictionary<string, string>
    
                {
    
                    ["CustomerName"] = "Acme Corporation",
    
                    ["PriorityLevel"] = "High",
    
                    ["Domain"] = "Cloud Services"
    
                }
    
            });
    
            
    
            string contextId = contextResult.ContextId;
    
            Console.WriteLine($"Created root context with ID: {contextId}");
    
            
    
            // 2. First interaction using the context
    
            var response1 = await _client.SendPromptAsync(
    
                "I'm having issues scaling my web service deployment in the cloud.", 
    
                new SendPromptOptions { RootContextId = contextId }
    
            );
    
            
    
            Console.WriteLine($"First response: {response1.GeneratedText}");
    
            
    
            // Second interaction - the model will have access to the previous conversation
    
            var response2 = await _client.SendPromptAsync(
    
                "Yes, we're using containerized deployments with Kubernetes.", 
    
                new SendPromptOptions { RootContextId = contextId }
    
            );
    
            
    
            Console.WriteLine($"Second response: {response2.GeneratedText}");
    
            
    
            // 3. Add metadata to the context based on conversation
    
            await _contextManager.UpdateContextMetadataAsync(contextId, new Dictionary<string, string>
    
            {
    
                ["TechnicalEnvironment"] = "Kubernetes",
    
                ["IssueType"] = "Scaling"
    
            });
    
            
    
            // 4. Get context information
    
            var contextInfo = await _contextManager.GetRootContextInfoAsync(contextId);
    
            
    
            Console.WriteLine("Context Information:");
    
            Console.WriteLine($"- Name: {contextInfo.Name}");
    
            Console.WriteLine($"- Created: {contextInfo.CreatedAt}");
    
            Console.WriteLine($"- Messages: {contextInfo.MessageCount}");
    
            
    
            // 5. When the conversation is complete, archive the context
    
            await _contextManager.ArchiveRootContextAsync(contextId);
    
            Console.WriteLine($"Archived context {contextId}");
    
        }
    
    }
    
    

    In the preceding code we've:

    1. Created a root context for a customer support session.

    1. Sent multiple messages within that context, allowing the model to maintain state.

    1. Updated the context with relevant metadata based on the conversation.

    1. Retrieved context information to understand the conversation history.

    1. Archived the context when the conversation was complete.

    Example: Root Context Implementation for financial analysis

    In this example, we will create a root context for a financial analysis session, demonstrating how to maintain state across multiple interactions.

    In the preceding code, we've:

    1. Created a root context for a financial analysis session.

    2. Sent multiple messages within that context, allowing the model to maintain state.

    3. Updated the context with relevant metadata based on the conversation.

    4. Generated a summary of the analysis session and stored it in the context metadata.

    5. Archived the context when the conversation was complete.

    Example: Root Context Management

    Managing root contexts effectively is crucial for maintaining conversation history and state. Below is an example of how to implement root context management.

    JavaScript Implementation

          apiKey
    
        });
    
        
    
        // Initialize context manager
    
        this.contextManager = new RootContextManager(this.client);
    
      }

    In the preceding code we've:

    1.

    Created a root context for a product support conversation with the function createConversationContext.

    In this case, the context is about database performance issues.

    1.

    Sent multiple messages within that context, allowing the model to maintain state with the function sendMessage.

    The messages being sent are about slow query performance and index configuration.

    1. Updated the context with relevant metadata based on the conversation.

    1. Generated a summary of the conversation and stored it in the context metadata with the function generateContextSummary.

    1. Archived the context when the conversation was complete with the function archiveContext.

    1. Handled errors gracefully to ensure robustness.

    In the preceding code we've:

    1. Created a root context for a technical support session with the function create_session. The context includes user information such as name and technical level.

    1.

    Sent multiple messages within that context, allowing the model to maintain state with the function send_message.

    The messages being sent are about issues with the auto-scaling feature.

    1. Retrieved conversation history using the function get_conversation_history, which provides context information and messages.

    1. Ended the session by archiving the context and generating a summary with the function end_session. The summary captures key points from the conversation.

    Root Context Best Practices

    Here are some best practices for managing root contexts effectively:

  • Create Focused Contexts: Create separate root contexts for different conversation purposes or domains to maintain clarity.
  • Set Expiration Policies: Implement policies to archive or delete old contexts to manage storage and comply with data retention policies.
  • Store Relevant Metadata: Use context metadata to store important information about the conversation that might be useful later.
  • Use Context IDs Consistently: Once a context is created, use its ID consistently for all related requests to maintain continuity.
  • Generate Summaries: When a context grows large, consider generating summaries to capture essential information while managing context size.
  • Implement Access Control: For multi-user systems, implement proper access controls to ensure privacy and security of conversation contexts.
  • Handle Context Limitations: Be aware of context size limitations and implement strategies for handling very long conversations.
  • Archive When Complete: Archive contexts when conversations are complete to free resources while preserving the conversation history.

    Routing in Model Context Protocol

    Routing is essential for directing requests to the appropriate models, tools, or services within an MCP ecosystem.

    Introduction

    Routing in the Model Context Protocol (MCP) involves directing requests to the most suitable models or services based on various criteria such as content type, user context, and system load.

    This ensures efficient processing and optimal resource utilization.

    Learning Objectives

    By the end of this lesson, you will be able to:

  • Understand the principles of routing in MCP.
  • Implement content-based routing to direct requests to specialized services.
  • Apply intelligent load balancing strategies to optimize resource utilization.
  • Implement dynamic tool routing based on request context.
  • Content-Based Routing

    Content-based routing directs requests to specialized services based on the content of the request.

    For example, requests related to code generation can be routed to a specialized code model, while creative writing requests can be sent to a creative writing model.

    Let's look at an example implementation in different programming languages.

    .NET

    
    // .NET Example: Content-based routing in MCP
    
    public class ContentBasedRouter
    
    {
    
        private readonly Dictionary<string, McpClient> _specializedClients;
    
        private readonly RoutingClassifier _classifier;
    
        
    
        public ContentBasedRouter()
    
        {
    
            // Initialize specialized clients for different domains
    
            _specializedClients = new Dictionary<string, McpClient>
    
            {
    
                ["code"] = new McpClient("https://code-specialized-mcp.com"),
    
                ["creative"] = new McpClient("https://creative-specialized-mcp.com"),
    
                ["scientific"] = new McpClient("https://scientific-specialized-mcp.com"),
    
                ["general"] = new McpClient("https://general-mcp.com")
    
            };
    
            
    
            // Initialize content classifier
    
            _classifier = new RoutingClassifier();
    
        }
    
        
    
        public async Task<McpResponse> RouteAndProcessAsync(string prompt, IDictionary<string, object> parameters = null)
    
        {
    
            // Classify the prompt to determine the best specialized service
    
            string category = await _classifier.ClassifyPromptAsync(prompt);
    
            
    
            // Get the appropriate client or fall back to general
    
            var client = _specializedClients.ContainsKey(category) 
    
                ? _specializedClients[category] 
    
                : _specializedClients["general"];
    
                
    
            Console.WriteLine($"Routing request to {category} specialized service");
    
            
    
            // Send request to the selected service
    
            return await client.SendPromptAsync(prompt, parameters);
    
        }
    
        
    
        // Simple classifier for routing decisions
    
        private class RoutingClassifier
    
        {
    
            public Task<string> ClassifyPromptAsync(string prompt)
    
            {
    
                prompt = prompt.ToLowerInvariant();
    
                
    
                if (prompt.Contains("code") || prompt.Contains("function") || 
    
                    prompt.Contains("program") || prompt.Contains("algorithm"))
    
                {
    
                    return Task.FromResult("code");
    
                }
    
                
    
                if (prompt.Contains("story") || prompt.Contains("creative") || 
    
                    prompt.Contains("imagine") || prompt.Contains("design"))
    
                {
    
                    return Task.FromResult("creative");
    
                }
    
                
    
                if (prompt.Contains("science") || prompt.Contains("research") || 
    
                    prompt.Contains("analyze") || prompt.Contains("study"))
    
                {
    
                    return Task.FromResult("scientific");
    
                }
    
                
    
                return Task.FromResult("general");
    
            }
    
        }
    
    }
    
    

    In the preceding code, we've:

  • Created a ContentBasedRouter class that routes requests based on the content of the prompt.
  • Initialized specialized clients for different domains (code, creative, scientific, general).
  • Implemented a simple classifier that determines the category of the prompt and routes it to the appropriate specialized service.
  • Used a fallback mechanism to route requests to a general service if no specialized service is available.
  • Implemented asynchronous processing to handle requests efficiently.
  • Used a dictionary to map content categories to specialized MCP clients.
  • Implemented a simple classifier that analyzes the prompt and returns the appropriate category.
  • Used the specialized client to send the request and receive a response.
  • Handled cases where the prompt does not match any specialized category by routing to a general service.
  • Intelligent Load Balancing

    Load balancing optimizes resource utilization and ensures high availability for MCP services. There are different ways to implement load balancing, such as round-robin, weighted response time, or content-aware strategies.

    Let's look at below example implementation that uses the following strategies:

  • Round Robin: Distributes requests evenly across available servers.
  • Weighted Response Time: Routes requests to servers based on their average response time.
  • Content-Aware: Routes requests to specialized servers based on the content of the request.
  • Java

    
    // Java Example: Intelligent load balancing for MCP servers
    
    public class McpLoadBalancer {
    
        private final List<McpServerNode> serverNodes;
    
        private final LoadBalancingStrategy strategy;
    
        
    
        public McpLoadBalancer(List<McpServerNode> nodes, LoadBalancingStrategy strategy) {
    
            this.serverNodes = new ArrayList<>(nodes);
    
            this.strategy = strategy;
    
        }
    
        
    
        public McpResponse processRequest(McpRequest request) {
    
            // Select the best server based on strategy
    
            McpServerNode selectedNode = strategy.selectNode(serverNodes, request);
    
            
    
            try {
    
                // Route the request to the selected node
    
                return selectedNode.processRequest(request);
    
            } catch (Exception e) {
    
                // Handle failure - implement retry or fallback logic
    
                System.err.println("Error processing request on node " + selectedNode.getId() + ": " + e.getMessage());
    
                
    
                // Mark node as potentially unhealthy
    
                selectedNode.recordFailure();
    
                
    
                // Try next best node as fallback
    
                List<McpServerNode> remainingNodes = new ArrayList<>(serverNodes);
    
                remainingNodes.remove(selectedNode);
    
                
    
                if (!remainingNodes.isEmpty()) {
    
                    McpServerNode fallbackNode = strategy.selectNode(remainingNodes, request);
    
                    return fallbackNode.processRequest(request);
    
                } else {
    
                    throw new RuntimeException("All MCP server nodes failed to process the request");
    
                }
    
            }
    
        }

                            return true;
    
                        }
    
                        return false;
    
                    })
    
                    .findFirst();
    
                
    
                // Return specialized node or least loaded node
    
                return specializedNode.orElse(
    
                    nodes.stream()
    
                        .filter(McpServerNode::isHealthy)
    
                        .min(Comparator.comparing(McpServerNode::getCurrentLoad))
    
                        .orElseThrow(() -> new RuntimeException("No healthy nodes available"))
    
                );
    
            }
    
        }
    
    }
    
    

    In the preceding code, we've:

  • Created a McpLoadBalancer class that manages a list of MCP server nodes and routes requests based on the selected load balancing strategy.
  • Implemented different load balancing strategies: RoundRobinStrategy, ResponseTimeStrategy, and ContentAwareStrategy.
  • Used a ScheduledExecutorService to periodically check the health of server nodes.
  • Implemented a health check mechanism that marks nodes as healthy or unhealthy based on their response to health checks.
  • Handled request processing with error handling and fallback logic to ensure high availability.
  • Used a McpServerNode class to represent individual MCP server nodes, including their health status, average response time, and current load.
  • Implemented a McpRequest class to encapsulate request details such as the prompt and allowed tools.
  • Used Java Streams to filter and select nodes based on health status and specialization.
  • Dynamic Tool Routing

    Tool routing ensures that tool calls are directed to the most appropriate service based on context.

    For example, a weather tool call may need to be routed to a regional endpoint based on the user's location, or a calculator tool may need to use a specific version of the API.

    Let's have a look at an example implementation that demonstrates dynamic tool routing based on request analysis, regional endpoints, and versioning support.

    Python

    
    # Python Example: Dynamic tool routing based on request analysis
    
    class McpToolRouter:
    
        def __init__(self):

            }
    
            
    
            # Regional endpoints for global distribution
    
            self.regional_endpoints = {
    
                "us": {
    
                    "weatherTool": "https://us-west.weather-service.example.com/api",

                raise
    
    

    In the preceding code, we've:

  • Created a McpToolRouter class that manages tool routing based on request analysis, regional endpoints, and versioning support.
  • Registered available tool endpoints and regional endpoints for global distribution.
  • Implemented dynamic routing logic that selects the appropriate endpoint based on user context, such as region and data residency requirements.
  • Implemented versioning support for tools, allowing users to specify which version of a tool they want to use.
  • Used asynchronous HTTP requests to execute tool calls and handle responses.
  • Sampling and Routing Architecture in MCP

    Sampling is a critical component of the Model Context Protocol (MCP) that allows for efficient request processing and routing.

    It involves analyzing incoming requests to determine the most appropriate model or service to handle them, based on various criteria such as content type, user context, and system load.

    Sampling and routing can be combined to create a robust architecture that optimizes resource utilization and ensures high availability.

    The sampling process can be used to classify requests, while routing directs them to the appropriate models or services.

    The diagram below illustrates how sampling and routing work together in a comprehensive MCP architecture:

    Sampling in Model Context Protocol

    Sampling is a powerful MCP feature that allows servers to request LLM completions through the client, enabling sophisticated agentic behaviors while maintaining security and privacy.

    The right sampling configuration can dramatically improve response quality and performance.

    MCP provides a standardized way to control how models generate text with specific parameters that influence randomness, creativity, and coherence.

    Introduction

    In this lesson, we will explore how to configure sampling parameters in MCP requests and understand the underlying protocol mechanics of sampling.

    Learning Objectives

    By the end of this lesson, you will be able to:

  • Understand the key sampling parameters available in MCP.
  • Configure sampling parameters for different use cases.
  • Implement deterministic sampling for reproducible results.
  • Dynamically adjust sampling parameters based on context and user preferences.
  • Apply sampling strategies to enhance model performance in various scenarios.
  • Understand how sampling works in the client-server flow of MCP.
  • How Sampling Works in MCP

    The sampling flow in MCP follows these steps:

    1. Server sends a sampling/createMessage request to the client

    2. Client reviews the request and can modify it

    3. Client samples from an LLM

    4. Client reviews the completion

    5. Client returns the result to the server

    This human-in-the-loop design ensures users maintain control over what the LLM sees and generates.

    Sampling Parameters Overview

    MCP defines the following sampling parameters that can be configured in client requests:

    Parameter Description Typical Range ----------- ------------- --------------- temperature Controls randomness in token selection 0.0 - 1.0 maxTokens Maximum number of tokens to generate Integer value stopSequences Custom sequences that stop generation when encountered Array of strings metadata Additional provider-specific parameters JSON object

    Many LLM providers support additional parameters through the metadata field, which may include:

    Common Extension Parameter Description Typical Range ----------- ------------- --------------- top_p Nucleus sampling - limits tokens to top cumulative probability 0.0 - 1.0 top_k Limits token selection to top K options 1 - 100 presence_penalty Penalizes tokens based on their presence in the text so far -2.0 - 2.0 frequency_penalty Penalizes tokens based on their frequency in the text so far -2.0 - 2.0 seed Specific random seed for reproducible results Integer value

    Example Request Format

    Here's an example of requesting sampling from a client in MCP:

    
    {
    
      "method": "sampling/createMessage",
    
      "params": {
    
        "messages": [
    
          {
    
            "role": "user",
    
            "content": {
    
              "type": "text",
    
              "text": "What files are in the current directory?"
    
            }
    
          }
    
        ],
    
        "systemPrompt": "You are a helpful file system assistant.",
    
        "includeContext": "thisServer",
    
        "maxTokens": 100,
    
        "temperature": 0.7
    
      }
    
    }
    
    

    Response Format

    The client returns a completion result:

    
    {
    
      "model": "string",  // Name of the model used
    
      "stopReason": "endTurn" | "stopSequence" | "maxTokens" | "string",
    
      "role": "assistant",
    
      "content": {
    
        "type": "text",
    
        "text": "string"
    
      }
    
    }
    
    

    Human in the Loop Controls

    MCP sampling is designed with human oversight in mind:

  • For prompts:
  • - Clients should show users the proposed prompt

    - Users should be able to modify or reject prompts

    - System prompts can be filtered or modified

    - Context inclusion is controlled by the client

  • For completions:
  • - Clients should show users the completion

    - Users should be able to modify or reject completions

    - Clients can filter or modify completions

    - Users control which model is used

    With these principles in mind, let's look at how to implement sampling in different programming languages, focusing on the parameters that are commonly supported across LLM providers.

    Security Considerations

    When implementing sampling in MCP, consider these security best practices:

  • Validate all message content before sending it to the client
  • Sanitize sensitive information from prompts and completions
  • Implement rate limits to prevent abuse
  • Monitor sampling usage for unusual patterns
  • Encrypt data in transit using secure protocols
  • Handle user data privacy according to relevant regulations
  • Audit sampling requests for compliance and security
  • Control cost exposure with appropriate limits
  • Implement timeouts for sampling requests
  • Handle model errors gracefully with appropriate fallbacks
  • Sampling parameters allow fine-tuning the behavior of language models to achieve the desired balance between deterministic and creative outputs.

    Let's look at how to configure these parameters in different programming languages.

    .NET

    
    // .NET Example: Configuring sampling parameters in MCP
    
    public class SamplingExample
    
    {
    
        public async Task RunWithSamplingAsync()
    
        {
    
            // Create MCP client with sampling configuration
    
            var client = new McpClient("https://mcp-server-url.com");
    
            
    
            // Create request with specific sampling parameters
    
            var request = new McpRequest
    
            {
    
                Prompt = "Generate creative ideas for a mobile app",
    
                SamplingParameters = new SamplingParameters
    
                {
    
                    Temperature = 0.8f,     // Higher temperature for more creative outputs
    
                    TopP = 0.95f,           // Nucleus sampling parameter
    
                    TopK = 40,              // Limit token selection to top K options
    
                    FrequencyPenalty = 0.5f, // Reduce repetition
    
                    PresencePenalty = 0.2f   // Encourage diversity
    
                },
    
                AllowedTools = new[] { "ideaGenerator", "marketAnalyzer" }
    
            };
    
            
    
            // Send request using specific sampling configuration
    
            var response = await client.SendRequestAsync(request);
    
            
    
            // Output results
    
            Console.WriteLine($"Generated with Temperature={request.SamplingParameters.Temperature}:");
    
            Console.WriteLine(response.GeneratedText);
    
        }
    
    }
    
    

    In the preceding code we've:

  • Created an MCP client with a specific server URL.
  • Configured a request with sampling parameters like temperature, top_p, and top_k.
  • Sent the request and printed the generated text.
  • Used:
  • - allowedTools to specify which tools the model can use during generation.

    In this case, we allowed the ideaGenerator and marketAnalyzer tools to assist in generating creative app ideas.

    - frequencyPenalty and presencePenalty to control repetition and diversity in the output.

    - temperature to control the randomness of the output, where higher values lead to more creative responses.

    - top_p to limit the selection of tokens to those that contribute to the top cumulative probability mass, enhancing the quality of generated text.

    - top_k to restrict the model to the top K most probable tokens, which can help in generating more coherent responses.

    - frequencyPenalty and presencePenalty to reduce repetition and encourage diversity in the generated text.

    JavaScript

        frequencyPenalty: 0.2, // Minimal repetition penalty
    
        presencePenalty: 0.1   // Minimal presence penalty
    
      };
    
      
    
      try {
    
        // Send two requests with different sampling configurations
    
        const creativeResponse = await client.sendPrompt(
    
          "Generate innovative ideas for sustainable urban transportation",
    
          {

      }
    
    }
    
    
    
    demonstrateSampling();
    
    

    In the preceding code we've:

  • Initialized an MCP client with a server URL and API key.
  • Configured two sets of sampling parameters: one for creative tasks and another for factual tasks.
  • Sent requests with these configurations, allowing the model to use specific tools for each task.
  • Printed the generated responses to demonstrate the effects of different sampling parameters.
  • Used allowedTools to specify which tools the model can use during generation. In this case, we allowed the ideaGenerator and environmentalImpactTool for creative tasks, and factChecker and dataAnalysisTool for factual tasks.
  • Used temperature to control the randomness of the output, where higher values lead to more creative responses.
  • Used top_p to limit the selection of tokens to those that contribute to the top cumulative probability mass, enhancing the quality of generated text.
  • Used frequencyPenalty and presencePenalty to reduce repetition and encourage diversity in the output.
  • Used top_k to restrict the model to the top K most probable tokens, which can help in generating more coherent responses.

    Deterministic Sampling

    For applications requiring consistent outputs, deterministic sampling ensures reproducible results. How it does that is by using a fixed random seed and setting the temperature to zero.

    Let's look at below sample implementation to demonstrate deterministic sampling in different programming languages.

    Java

    
    // Java Example: Deterministic responses with fixed seed
    
    public class DeterministicSamplingExample {
    
        public void demonstrateDeterministicResponses() {
    
            McpClient client = new McpClient.Builder()
    
                .setServerUrl("https://mcp-server-example.com")
    
                .build();
    
                
    
            long fixedSeed = 12345; // Using a fixed seed for deterministic results
    
            
    
            // First request with fixed seed
    
            McpRequest request1 = new McpRequest.Builder()
    
                .setPrompt("Generate a random number between 1 and 100")
    
                .setSeed(fixedSeed)
    
                .setTemperature(0.0) // Zero temperature for maximum determinism
    
                .build();
    
                
    
            // Second request with the same seed
    
            McpRequest request2 = new McpRequest.Builder()
    
                .setPrompt("Generate a random number between 1 and 100")
    
                .setSeed(fixedSeed)
    
                .setTemperature(0.0)
    
                .build();
    
            
    
            // Execute both requests
    
            McpResponse response1 = client.sendRequest(request1);
    
            McpResponse response2 = client.sendRequest(request2);
    
            
    
            // Responses should be identical due to same seed and temperature=0
    
            System.out.println("Response 1: " + response1.getGeneratedText());
    
            System.out.println("Response 2: " + response2.getGeneratedText());
    
            System.out.println("Are responses identical: " + 
    
                response1.getGeneratedText().equals(response2.getGeneratedText()));
    
        }
    
    }
    
    

    In the preceding code we've:

  • Created an MCP client with a specified server URL.
  • Configured two requests with the same prompt, fixed seed, and zero temperature.
  • Sent both requests and printed the generated text.
  • Demonstrated that the responses are identical due to the deterministic nature of the sampling configuration (same seed and temperature).
  • Used setSeed to specify a fixed random seed, ensuring that the model generates the same output for the same input every time.
  • Set temperature to zero to ensure maximum determinism, meaning the model will always select the most probable next token without randomness.
  • JavaScript

    
    // JavaScript Example: Deterministic responses with seed control
    
    const { McpClient } = require('@mcp/client');
    
    
    
    async function deterministicSampling() {
    
      const client = new McpClient({
    
        serverUrl: 'https://mcp-server-example.com'
    
      });
    
      
    
      const fixedSeed = 12345;
    
      const prompt = "Generate a random password with 8 characters";
    
      
    
      try {
    
        // First request with fixed seed
    
        const response1 = await client.sendPrompt(prompt, {
    
          seed: fixedSeed,
    
          temperature: 0.0  // Zero temperature for maximum determinism
    
        });
    
        
    
        // Second request with same seed and temperature
    
        const response2 = await client.sendPrompt(prompt, {
    
          seed: fixedSeed,
    
          temperature: 0.0
    
        });
    
        
    
        // Third request with different seed but same temperature
    
        const response3 = await client.sendPrompt(prompt, {
    
          seed: 67890,
    
          temperature: 0.0
    
        });
    
        
    
        console.log('Response 1:', response1.generatedText);
    
        console.log('Response 2:', response2.generatedText);
    
        console.log('Response 3:', response3.generatedText);
    
        console.log('Responses 1 and 2 match:', response1.generatedText === response2.generatedText);
    
        console.log('Responses 1 and 3 match:', response1.generatedText === response3.generatedText);
    
        
    
      } catch (error) {
    
        console.error('Error in deterministic sampling demo:', error);
    
      }
    
    }
    
    
    
    deterministicSampling();
    
    

    In the preceding code we've:

  • Initialized an MCP client with a server URL.
  • Configured two requests with the same prompt, fixed seed, and zero temperature.
  • Sent both requests and printed the generated text.
  • Demonstrated that the responses are identical due to the deterministic nature of the sampling configuration (same seed and temperature).
  • Used seed to specify a fixed random seed, ensuring that the model generates the same output for the same input every time.
  • Set temperature to zero to ensure maximum determinism, meaning the model will always select the most probable next token without randomness.
  • Used a different seed for the third request to show that changing the seed results in different outputs, even with the same prompt and temperature.

    Dynamic Sampling Configuration

    Intelligent sampling adapts parameters based on the context and requirements of each request. That means dynamically adjusting parameters like temperature, top_p, and penalties based on the task type, user preferences, or historical performance.

    Let's look at how to implement dynamic sampling in different programming languages.

    Python

    
    # Python Example: Dynamic sampling based on request context
    
    class DynamicSamplingService:
    
        def __init__(self, mcp_client):
    
            self.client = mcp_client
    
            
    
        async def generate_with_adaptive_sampling(self, prompt, task_type, user_preferences=None):
    
            """Uses different sampling strategies based on task type and user preferences"""
    
            
    
            # Define sampling presets for different task types
    
            sampling_presets = {
    
                "creative": {"temperature": 0.9, "top_p": 0.95, "frequency_penalty": 0.7},
    
                "factual": {"temperature": 0.2, "top_p": 0.85, "frequency_penalty": 0.2},
    
                "code": {"temperature": 0.3, "top_p": 0.9, "frequency_penalty": 0.5},
    
                "analytical": {"temperature": 0.4, "top_p": 0.92, "frequency_penalty": 0.3}
    
            }
    
            
    
            # Select base preset
    
            sampling_params = sampling_presets.get(task_type, sampling_presets["factual"])
    
            
    
            # Adjust based on user preferences if provided
    
            if user_preferences:
    
                if "creativity_level" in user_preferences:
    
                    # Scale temperature based on creativity preference (1-10)
    
                    creativity = min(max(user_preferences["creativity_level"], 1), 10) / 10
    
                    sampling_params["temperature"] = 0.1 + (0.9 * creativity)
    
                
    
                if "diversity" in user_preferences:
    
                    # Adjust top_p based on desired response diversity
    
                    diversity = min(max(user_preferences["diversity"], 1), 10) / 10
    
                    sampling_params["top_p"] = 0.6 + (0.39 * diversity)
    
            
    
            # Create and send request with custom sampling parameters
    
            response = await self.client.send_request(
    
                prompt=prompt,
    
                temperature=sampling_params["temperature"],
    
                top_p=sampling_params["top_p"],
    
                frequency_penalty=sampling_params["frequency_penalty"]
    
            )
    
            
    
            # Return response with sampling metadata for transparency
    
            return {
    
                "text": response.generated_text,
    
                "applied_sampling": sampling_params,
    
                "task_type": task_type
    
            }
    
    

    In the preceding code we've:

  • Created a DynamicSamplingService class that manages adaptive sampling.
  • Defined sampling presets for different task types (creative, factual, code, analytical).
  • Selected a base sampling preset based on the task type.
  • Adjusted the sampling parameters based on user preferences, such as creativity level and diversity.
  • Sent the request with the dynamically configured sampling parameters.
  • Returned the generated text along with the applied sampling parameters and task type for transparency.
  • Used temperature to control the randomness of the output, where higher values lead to more creative responses.
  • Used top_p to limit the selection of tokens to those that contribute to the top cumulative probability mass, enhancing the quality of generated text.
  • Used frequency_penalty to reduce repetition and encourage diversity in the output.
  • Used user_preferences to allow customization of the sampling parameters based on user-defined creativity and diversity levels.
  • Used task_type to determine the appropriate sampling strategy for the request, allowing for more tailored responses based on the nature of the task.
  • Used send_request method to send the prompt with the configured sampling parameters, ensuring that the model generates text according to the specified requirements.
  • Used generated_text to retrieve the model's response, which is then returned along with the sampling parameters and task type for further analysis or display.
  • Used min and max functions to ensure that user preferences are clamped within valid ranges, preventing invalid sampling configurations.
  • JavaScript Dynamic

    
    // JavaScript Example: Dynamic sampling configuration based on user context
    
    class AdaptiveSamplingManager {
    
      constructor(mcpClient) {
    
        this.client = mcpClient;

    In the preceding code we've:

  • Created an AdaptiveSamplingManager class that manages dynamic sampling based on task type and user preferences.
  • Defined sampling profiles for different task types (creative, factual, code, conversational).
  • Implemented a method to detect the task type from the prompt using simple heuristics.
  • Calculated sampling parameters based on the detected task type and user preferences.
  • Applied learned adjustments based on historical performance to optimize sampling parameters.
  • Recorded performance for future adjustments, allowing the system to learn from past interactions.
  • Sent requests with dynamically configured sampling parameters and returned the generated text along with applied parameters and detected task type.
  • Used:
  • - userPreferences to allow customization of the sampling parameters based on user-defined creativity, precision, and consistency levels.

    - detectTaskType to determine the nature of the task based on the prompt, allowing for more tailored responses.

    - recordPerformance to log the performance of generated responses, enabling the system to adapt and improve over time.

    - applyLearnedAdjustments to modify sampling parameters based on historical performance, enhancing the model's ability to generate high-quality responses.

    - generateResponse to encapsulate the entire process of generating a response with adaptive sampling, making it easy to call with different prompts and contexts.

    - allowedTools to specify which tools the model can use during generation, allowing for more context-aware responses.

    - feedbackScore to allow users to provide feedback on the quality of the generated response, which can be used to further refine the model's performance over time.

    - performanceHistory to maintain a record of past interactions, enabling the system to learn from previous successes and failures.

    - getSamplingParameters to dynamically adjust sampling parameters based on the context of the request, allowing for more flexible and responsive model behavior.

    - detectTaskType to classify the task based on the prompt, enabling the system to apply appropriate sampling strategies for different types of requests.

    - samplingProfiles to define base sampling configurations for different task types, allowing for quick adjustments based on the nature of the request.

    Scalability and High-Performance MCP

    For enterprise deployments, MCP implementations often need to handle high volumes of requests with minimal latency.

    Introduction

    In this lesson, we will explore strategies for scaling MCP servers to handle large workloads efficiently. We will cover horizontal and vertical scaling, resource optimization, and distributed architectures.

    Learning Objectives

    By the end of this lesson, you will be able to:

  • Implement horizontal scaling using load balancing and distributed caching.
  • Optimize MCP servers for vertical scaling and resource management.
  • Design distributed MCP architectures for high availability and fault tolerance.
  • Utilize advanced tools and techniques for performance monitoring and optimization.
  • Apply best practices for scaling MCP servers in production environments.
  • Scalability Strategies

    There are several strategies to scale MCP servers effectively:

  • Horizontal Scaling: Deploy multiple instances of MCP servers behind a load balancer to distribute incoming requests evenly.
  • Vertical Scaling: Optimize a single MCP server instance to handle more requests by increasing resources (CPU, memory) and fine-tuning configurations.
  • Resource Optimization: Use efficient algorithms, caching, and asynchronous processing to reduce resource consumption and improve response times.
  • Distributed Architecture: Implement a distributed system where multiple MCP nodes work together, sharing the load and providing redundancy.
  • Horizontal Scaling

    Horizontal scaling involves deploying multiple instances of MCP servers and using a load balancer to distribute incoming requests. This approach allows you to handle more requests simultaneously and provides fault tolerance.

    Let's look at an example of how to configure horizontal scaling and MCP.

    .NET

    
    // ASP.NET Core MCP load balancing configuration
    
    public class McpLoadBalancedStartup
    
    {
    
        public void ConfigureServices(IServiceCollection services)
    
        {
    
            // Configure distributed cache for session state
    
            services.AddStackExchangeRedisCache(options =>
    
            {
    
                options.Configuration = Configuration.GetConnectionString("RedisConnection");
    
                options.InstanceName = "MCP_";
    
            });
    
            
    
            // Configure MCP with distributed caching
    
            services.AddMcpServer(options =>
    
            {
    
                options.ServerName = "Scalable MCP Server";
    
                options.ServerVersion = "1.0.0";
    
                options.EnableDistributedCaching = true;
    
                options.CacheExpirationMinutes = 60;
    
            });
    
            
    
            // Register tools
    
            services.AddMcpTool<HighPerformanceTool>();
    
        }
    
    }
    
    

    In the preceding code we've:

  • Configured a distributed cache using Redis to store session state and tool data.
  • Enabled distributed caching in the MCP server configuration.
  • Registered a high-performance tool that can be used across multiple MCP instances.

    Vertical Scaling and Resource Optimization

    Vertical scaling focuses on optimizing a single MCP server instance to handle more requests efficiently.

    This can be achieved by fine-tuning configurations, using efficient algorithms, and managing resources effectively.

    For example, you can adjust thread pools, request timeouts, and memory limits to improve performance.

    Let's look at an example of how to optimize an MCP server for vertical scaling and resource management.

    Java

    
    // Java MCP server with resource optimization
    
    public class OptimizedMcpServer {
    
        public static McpServer createOptimizedServer() {
    
            // Configure thread pool for optimal performance
    
            int processors = Runtime.getRuntime().availableProcessors();
    
            int optimalThreads = processors * 2; // Common heuristic for I/O-bound tasks
    
            
    
            ExecutorService executorService = new ThreadPoolExecutor(
    
                processors,       // Core pool size
    
                optimalThreads,   // Maximum pool size 
    
                60L,              // Keep-alive time
    
                TimeUnit.SECONDS,
    
                new ArrayBlockingQueue<>(1000), // Request queue size
    
                new ThreadPoolExecutor.CallerRunsPolicy() // Backpressure strategy
    
            );
    
            
    
            // Configure and build MCP server with resource constraints
    
            return new McpServer.Builder()
    
                .setName("High-Performance MCP Server")
    
                .setVersion("1.0.0")
    
                .setPort(5000)
    
                .setExecutor(executorService)
    
                .setMaxRequestSize(1024 * 1024) // 1MB
    
                .setMaxConcurrentRequests(100)
    
                .setRequestTimeoutMs(5000) // 5 seconds
    
                .build();
    
        }
    
    }
    
    

    In the preceding code, we have:

  • Configured a thread pool with an optimal number of threads based on the number of available processors.
  • Set resource constraints such as maximum request size, maximum concurrent requests, and request timeout.
  • Used a backpressure strategy to handle overload situations gracefully.
  • ---

    Distributed Architecture

    Distributed architectures involve multiple MCP nodes working together to handle requests, share resources, and provide redundancy.

    This approach enhances scalability and fault tolerance by allowing nodes to communicate and coordinate through a distributed system.

    Let's look at an example of how to implement a distributed MCP server architecture using Redis for coordination.

    Python

    
    # Python MCP server in distributed architecture
    
    from mcp_server import AsyncMcpServer
    
    import asyncio
    
    import aioredis
    
    import uuid
    
    
    
    class DistributedMcpServer:
    
        def __init__(self, node_id=None):
    
            self.node_id = node_id or str(uuid.uuid4())
    
            self.redis = None
    
            self.server = None
    
        
    
        async def initialize(self):
    
            # Connect to Redis for coordination
    
            self.redis = await aioredis.create_redis_pool("redis://redis-master:6379")
    
            
    
            # Register this node with the cluster
    
            await self.redis.sadd("mcp:nodes", self.node_id)
    
            await self.redis.hset(f"mcp:node:{self.node_id}", "status", "starting")
    
            
    
            # Create the MCP server
    
            self.server = AsyncMcpServer(
    
                name=f"MCP Node {self.node_id[:8]}",
    
                version="1.0.0",
    
                port=5000,
    
                max_concurrent_requests=50
    
            )
    
            
    
            # Register tools - each node might specialize in certain tools
    
            self.register_tools()
    
            
    
            # Start heartbeat mechanism
    
            asyncio.create_task(self._heartbeat())
    
            
    
            # Start server
    
            await self.server.start()
    
            
    
            # Update node status
    
            await self.redis.hset(f"mcp:node:{self.node_id}", "status", "running")
    
            print(f"MCP Node {self.node_id[:8]} running on port 5000")
    
        
    
        def register_tools(self):
    
            # Register common tools across all nodes
    
            self.server.register_tool(CommonTool1())
    
            self.server.register_tool(CommonTool2())
    
            
    
            # Register specialized tools for this node (could be based on node_id or config)
    
            if int(self.node_id[-1], 16) % 3 == 0:  # Simple way to distribute specialized tools
    
                self.server.register_tool(SpecializedTool1())
    
            elif int(self.node_id[-1], 16) % 3 == 1:
    
                self.server.register_tool(SpecializedTool2())
    
            else:
    
                self.server.register_tool(SpecializedTool3())
    
        
    
        async def _heartbeat(self):
    
            """Periodic heartbeat to indicate node health"""
    
            while True:
    
                try:
    
                    await self.redis.hset(
    
                        f"mcp:node:{self.node_id}", 
    
                        mapping={
    
                            "lastHeartbeat": int(time.time()),
    
                            "load": len(self.server.active_requests),
    
                            "maxLoad": self.server.max_concurrent_requests
    
                        }
    
                    )
    
                    await asyncio.sleep(5)  # Heartbeat every 5 seconds
    
                except Exception as e:
    
                    print(f"Heartbeat error: {e}")
    
                    await asyncio.sleep(1)
    
        
    
        async def shutdown(self):
    
            await self.redis.hset(f"mcp:node:{self.node_id}", "status", "stopping")
    
            await self.server.stop()
    
            await self.redis.srem("mcp:nodes", self.node_id)
    
            await self.redis.delete(f"mcp:node:{self.node_id}")
    
            self.redis.close()
    
            await self.redis.wait_closed()
    
    

    In the preceding code, we have:

  • Created a distributed MCP server that registers itself with a Redis instance for coordination.
  • Implemented a heartbeat mechanism to update the node's status and load in Redis.
  • Registered tools that can be specialized based on the node's ID, allowing for load distribution across nodes.
  • Provided a shutdown method to clean up resources and deregister the node from the cluster.
  • Used asynchronous programming to handle requests efficiently and maintain responsiveness.
  • Utilized Redis for coordination and state management across distributed nodes.

    MCP Security Best Practices - Advanced Implementation Guide

    > Current Standard: This guide reflects MCP Specification 2025-06-18 security requirements and official MCP Security Best Practices.

    Security is critical for MCP implementations, especially in enterprise environments.

    This advanced guide explores comprehensive security practices for production MCP deployments, addressing both traditional security concerns and AI-specific threats unique to the Model Context Protocol.

    Introduction

    The Model Context Protocol (MCP) introduces unique security challenges that extend beyond traditional software security.

    As AI systems gain access to tools, data, and external services, new attack vectors emerge including prompt injection, tool poisoning, session hijacking, confused deputy problems, and token passthrough vulnerabilities.

    This lesson explores advanced security implementations based on the latest MCP specification (2025-06-18), Microsoft security solutions, and established enterprise security patterns.

    Core Security Principles

    From MCP Specification (2025-06-18):

  • Explicit Prohibitions: MCP servers MUST NOT accept tokens not issued for them, and MUST NOT use sessions for authentication
  • Mandatory Verification: All inbound requests MUST be verified, and user consent MUST be obtained for proxy operations
  • Secure Defaults: Implement fail-safe security controls with defense-in-depth approaches
  • User Control: Users must provide explicit consent before any data access or tool execution
  • Learning Objectives

    By the end of this advanced lesson, you will be able to:

  • Implement Advanced Authentication: Deploy external identity provider integration with Microsoft Entra ID and OAuth 2.1 security patterns
  • Prevent AI-Specific Attacks: Protect against prompt injection, tool poisoning, and session hijacking using Microsoft Prompt Shields and Azure Content Safety
  • Apply Enterprise Security: Implement comprehensive logging, monitoring, and incident response for production MCP deployments
  • Secure Tool Execution: Design sandboxed execution environments with proper isolation and resource controls
  • Address MCP Vulnerabilities: Identify and mitigate confused deputy problems, token passthrough vulnerabilities, and supply chain risks
  • Integrate Microsoft Security: Leverage Azure security services and GitHub Advanced Security for comprehensive protection
  • MANDATORY Security Requirements

    Critical Requirements from MCP Specification (2025-06-18):

    
    Authentication & Authorization:
    
      token_validation: "MUST NOT accept tokens not issued for MCP server"
    
      session_authentication: "MUST NOT use sessions for authentication"
    
      request_verification: "MUST verify ALL inbound requests"
    
      
    
    Proxy Operations:  
    
      user_consent: "MUST obtain consent for dynamic client registration"
    
      oauth_security: "MUST implement OAuth 2.1 with PKCE"
    
      redirect_validation: "MUST validate redirect URIs strictly"
    
      
    
    Session Management:
    
      session_ids: "MUST use secure, non-deterministic generation" 
    
      user_binding: "SHOULD bind to user-specific information"
    
      transport_security: "MUST use HTTPS for all communications"
    
    

    Advanced Authentication and Authorization

    Modern MCP implementations benefit from the specification's evolution toward external identity provider delegation, significantly improving security posture over custom authentication implementations.

    Microsoft Entra ID Integration

    The current MCP specification (2025-06-18) allows delegation to external identity providers like Microsoft Entra ID, providing enterprise-grade security features:

    Security Benefits:

  • Enterprise-grade multi-factor authentication (MFA)
  • Conditional access policies based on risk assessment
  • Centralized identity lifecycle management
  • Advanced threat protection and anomaly detection
  • Compliance with enterprise security standards
  • .NET Implementation with Entra ID

    Lesson: Building a Web Search MCP Server

    This chapter demonstrates how to build a real-world AI agent that integrates with external APIs, handles diverse data types, manages errors, and orchestrates multiple tools—all in a production-ready format. You'll see:

  • Integration with external APIs requiring authentication
  • Handling diverse data types from multiple endpoints
  • Robust error handling and logging strategies
  • Multi-tool orchestration in a single server
  • By the end, you'll have practical experience with patterns and best practices that are essential for advanced AI and LLM-powered applications.

    Introduction

    In this lesson, you'll learn how to build an advanced MCP server and client that extends LLM capabilities with real-time web data using SerpAPI.

    This is a critical skill for developing dynamic AI agents that can access up-to-date information from the web.

    Learning Objectives

    By the end of this lesson, you will be able to:

  • Integrate external APIs (like SerpAPI) securely into an MCP server
  • Implement multiple tools for web, news, product search, and Q&A
  • Parse and format structured data for LLM consumption
  • Handle errors and manage API rate limits effectively
  • Build and test both automated and interactive MCP clients
  • Web Search MCP Server

    This section introduces the architecture and features of the Web Search MCP Server. You'll see how FastMCP and SerpAPI are used together to extend LLM capabilities with real-time web data.

    Overview

    This implementation features four tools that showcase MCP's ability to handle diverse, external API-driven tasks securely and efficiently:

  • general_search: For broad web results
  • news_search: For recent headlines
  • product_search: For e-commerce data
  • qna: For question-and-answer snippets
  • Features

  • Code Examples: Includes language-specific code blocks for Python (and easily extendable to other languages) using code pivots for clarity
  • Python

    
    # Example usage of the general_search tool
    
    from mcp import ClientSession, StdioServerParameters
    
    from mcp.client.stdio import stdio_client
    
    
    
    async def run_search():
    
        server_params = StdioServerParameters(
    
            command="python",
    
            args=["server.py"],
    
        )
    
        async with stdio_client(server_params) as (reader, writer):
    
            async with ClientSession(reader, writer) as session:
    
                await session.initialize()
    
                result = await session.call_tool("general_search", arguments={"query": "open source LLMs"})
    
                print(result)
    
    

    ---

    Before running the client, it's helpful to understand what the server does.

    The server.py file implements the MCP server, exposing tools for web, news, product search, and Q&A by integrating with SerpAPI.

    It handles incoming requests, manages API calls, parses responses, and returns structured results to the client.

    You can review the full implementation in server.py.

    Here is a brief example of how the server defines and registers a tool:

    Python Server

    
    # server.py (excerpt)
    
    from mcp.server import MCPServer, Tool
    
    
    
    async def general_search(query: str):
    
        # ...implementation...
    
    
    
    server = MCPServer()
    
    server.add_tool(Tool("general_search", general_search))
    
    
    
    if __name__ == "__main__":
    
        server.run()
    
    

    ---

  • External API Integration: Demonstrates secure handling of API keys and external requests
  • Structured Data Parsing: Shows how to transform API responses into LLM-friendly formats
  • Error Handling: Robust error handling with appropriate logging
  • Interactive Client: Includes both automated tests and an interactive mode for testing
  • Context Management: Leverages MCP Context for logging and tracking requests
  • Prerequisites

    Before you begin, make sure your environment is set up properly by following these steps. This will ensure that all dependencies are installed and your API keys are configured correctly for seamless development and testing.

  • Python 3.8 or higher
  • SerpAPI API Key (Sign up at SerpAPI - free tier available)
  • Installation

    To get started, follow these steps to set up your environment:

    1. Install dependencies using uv (recommended) or pip:

    
    # Using uv (recommended)
    
    uv pip install -r requirements.txt
    
    
    
    # Using pip
    
    pip install -r requirements.txt
    
    

    2. Create a .env file in the project root with your SerpAPI key:

    
    SERPAPI_KEY=your_serpapi_key_here
    
    

    Usage

    The Web Search MCP Server is the core component that exposes tools for web, news, product search, and Q&A by integrating with SerpAPI. It handles incoming requests, manages API calls, parses responses, and returns structured results to the client.

    You can review the full implementation in server.py.

    Running the Server

    To start the MCP server, use the following command:

    
    python server.py
    
    

    The server will run as a stdio-based MCP server that the client can connect to directly.

    Client Modes

    The client (client.py) supports two modes for interacting with the MCP server:

  • Normal mode: Runs automated tests that exercise all the tools and verify their responses. This is useful for quickly checking that the server and tools are working as expected.
  • Interactive mode: Starts a menu-driven interface where you can manually select and call tools, enter custom queries, and see results in real time. This is ideal for exploring the server's capabilities and experimenting with different inputs.
  • You can review the full implementation in client.py.

    Running the Client

    To run the automated tests (this will automatically start the server):

    
    python client.py
    
    

    Or run in interactive mode:

    
    python client.py --interactive
    
    

    Testing with Different Methods

    There are several ways to test and interact with the tools provided by the server, depending on your needs and workflow.

    Writing Custom Test Scripts with the MCP Python SDK

    You can also build your own test scripts using the MCP Python SDK:

    Python

    
    from mcp import ClientSession, StdioServerParameters
    
    from mcp.client.stdio import stdio_client
    
    
    
    async def test_custom_query():
    
        server_params = StdioServerParameters(
    
            command="python",
    
            args=["server.py"],
    
        )
    
        
    
        async with stdio_client(server_params) as (reader, writer):
    
            async with ClientSession(reader, writer) as session:
    
                await session.initialize()
    
                # Call tools with your custom parameters
    
                result = await session.call_tool("general_search", 
    
                                               arguments={"query": "your custom query"})
    
                # Process the result
    
    

    ---

    In this context, a "test script" means a custom Python program you write to act as a client for the MCP server.

    Instead of being a formal unit test, this script lets you programmatically connect to the server, call any of its tools with parameters you choose, and inspect the results.

    This approach is useful for:

  • Prototyping and experimenting with tool calls
  • Validating how the server responds to different inputs
  • Automating repeated tool invocations
  • Building your own workflows or integrations on top of the MCP server
  • You can use test scripts to quickly try out new queries, debug tool behavior, or even as a starting point for more advanced automation. Below is an example of how to use the MCP Python SDK to create such a script:

    Tool Descriptions

    You can use the following tools provided by the server to perform different types of searches and queries. Each tool is described below with its parameters and example usage.

    Advanced Concepts in This Lesson

    Before you start building, here are some important advanced concepts that will appear throughout this chapter. Understanding these will help you follow along, even if you're new to them:

  • Multi-tool Orchestration: This means running several different tools (like web search, news search, product search, and Q&A) within a single MCP server. It allows your server to handle a variety of tasks, not just one.
  • API Rate Limit Handling: Many external APIs (like SerpAPI) limit how many requests you can make in a certain time. Good code checks for these limits and handles them gracefully, so your app doesn't break if you hit a limit.
  • Structured Data Parsing: API responses are often complex and nested. This concept is about turning those responses into clean, easy-to-use formats that are friendly for LLMs or other programs.
  • Error Recovery: Sometimes things go wrong—maybe the network fails, or the API doesn't return what you expect. Error recovery means your code can handle these problems and still give useful feedback, instead of crashing.
  • Parameter Validation: This is about checking that all inputs to your tools are correct and safe to use. It includes setting default values and making sure the types are right, which helps prevent bugs and confusion.
  • This section will help you diagnose and resolve common issues you might encounter while working with the Web Search MCP Server.

    If you run into errors or unexpected behavior while working with the Web Search MCP Server, this troubleshooting section provides solutions to the most common issues.

    Review these tips before seeking further help—they often resolve problems quickly.

    Troubleshooting

    When working with the Web Search MCP Server, you may occasionally run into issues—this is normal when developing with external APIs and new tools.

    This section provides practical solutions to the most common problems, so you can get back on track quickly.

    If you encounter an error, start here: the tips below address the issues that most users face and can often resolve your problem without extra help.

    Common Issues

    Below are some of the most frequent problems users encounter, along with clear explanations and steps to resolve them:

    1. Missing SERPAPI_KEY in .env file

    - If you see the error SERPAPI_KEY environment variable not found, it means your application can't find the API key needed to access SerpAPI.

    To fix this, create a file named .env in your project root (if it doesn't already exist) and add a line like SERPAPI_KEY=your_serpapi_key_here.

    Make sure to replace your_serpapi_key_here with your actual key from the SerpAPI website.

    2. Module not found errors

    - Errors such as ModuleNotFoundError: No module named 'httpx' indicate that a required Python package is missing.

    This usually happens if you haven't installed all the dependencies.

    To resolve this, run pip install -r requirements.txt in your terminal to install everything your project needs.

    3. Connection issues

    - If you get an error like Error during client execution, it often means the client can't connect to the server, or the server isn't running as expected.

    Double-check that both the client and server are compatible versions, and that server.py is present and running in the correct directory.

    Restarting both the server and client can also help.

    4. SerpAPI errors

    - Seeing Search API returned error status: 401 means your SerpAPI key is missing, incorrect, or expired.

    Go to your SerpAPI dashboard, verify your key, and update your .env file if needed.

    If your key is correct but you still see this error, check if your free tier has run out of quota.

    Debug Mode

    By default, the app logs only important information. If you want to see more details about what's happening (for example, to diagnose tricky issues), you can enable DEBUG mode. This will show you much more about each step the app is taking.

    Example: Normal Output

    
    2025-06-01 10:15:23,456 - __main__ - INFO - Calling general_search with params: {'query': 'open source LLMs'}
    
    2025-06-01 10:15:24,123 - __main__ - INFO - Successfully called general_search
    
    
    
    GENERAL_SEARCH RESULTS:
    
    ... (search results here) ...
    
    

    Example: DEBUG Output

    
    2025-06-01 10:15:23,456 - __main__ - INFO - Calling general_search with params: {'query': 'open source LLMs'}
    
    2025-06-01 10:15:23,457 - httpx - DEBUG - HTTP Request: GET https://serpapi.com/search ...
    
    2025-06-01 10:15:23,458 - httpx - DEBUG - HTTP Response: 200 OK ...
    
    2025-06-01 10:15:24,123 - __main__ - INFO - Successfully called general_search
    
    
    
    GENERAL_SEARCH RESULTS:
    
    ... (search results here) ...
    
    

    Notice how DEBUG mode includes extra lines about HTTP requests, responses, and other internal details. This can be very helpful for troubleshooting.

    To enable DEBUG mode, set the logging level to DEBUG at the top of your client.py or server.py:

    Python

    
    # At the top of your client.py or server.py
    
    import logging
    
    logging.basicConfig(
    
        level=logging.DEBUG,  # Change from INFO to DEBUG
    
        format="%(asctime)s - %(name)s - %(levelname)s - %(message)s"
    
    )

    Model Context Protocol for Real-Time Data Streaming

    Overview

    Real-time data streaming has become essential in today's data-driven world, where businesses and applications require immediate access to information to make timely decisions.

    The Model Context Protocol (MCP) represents a significant advancement in optimizing these real-time streaming processes, enhancing data processing efficiency, maintaining contextual integrity, and improving overall system performance.

    This module explores how MCP transforms real-time data streaming by providing a standardized approach to context management across AI models, streaming platforms, and applications.

    Introduction to Real-Time Data Streaming

    Real-time data streaming is a technological paradigm that enables the continuous transfer, processing, and analysis of data as it's generated, allowing systems to react immediately to new information.

    Unlike traditional batch processing that operates on static datasets, streaming processes data in motion, delivering insights and actions with minimal latency.

    Core Concepts of Real-Time Data Streaming:

  • Continuous Data Flow: Data is processed as a continuous, never-ending stream of events or records.
  • Low Latency Processing: Systems are designed to minimize the time between data generation and processing.
  • Scalability: Streaming architectures must handle variable data volumes and velocity.
  • Fault Tolerance: Systems need to be resilient against failures to ensure uninterrupted data flow.
  • Stateful Processing: Maintaining context across events is crucial for meaningful analysis.
  • The Model Context Protocol and Real-Time Streaming

    The Model Context Protocol (MCP) addresses several critical challenges in real-time streaming environments:

    1. Contextual Continuity: MCP standardizes how context is maintained across distributed streaming components, ensuring that AI models and processing nodes have access to relevant historical and environmental context.

    2. Efficient State Management: By providing structured mechanisms for context transmission, MCP reduces the overhead of state management in streaming pipelines.

    3. Interoperability: MCP creates a common language for context sharing between diverse streaming technologies and AI models, enabling more flexible and extensible architectures.

    4. Streaming-Optimized Context: MCP implementations can prioritize which context elements are most relevant for real-time decision making, optimizing for both performance and accuracy.

    5. Adaptive Processing: With proper context management through MCP, streaming systems can dynamically adjust processing based on evolving conditions and patterns in the data.

    In modern applications ranging from IoT sensor networks to financial trading platforms, the integration of MCP with streaming technologies enables more intelligent, context-aware processing that can respond appropriately to complex, evolving situations in real time.

    Learning Objectives

    By the end of this lesson, you will be able to:

  • Understand the fundamentals of real-time data streaming and its challenges
  • Explain how the Model Context Protocol (MCP) enhances real-time data streaming

    Traditional data streaming approaches face several limitations:

    1. Context Loss: Difficulty maintaining context across distributed systems

    2. Scalability Issues: Challenges in scaling to handle high-volume, high-velocity data

    3. Integration Complexity: Problems with interoperability between different systems

    4. Latency Management: Balancing throughput with processing time

    5. Data Consistency: Ensuring data accuracy and completeness across the stream

    Understanding Model Context Protocol (MCP)

    What is MCP?

    The Model Context Protocol (MCP) is a standardized communication protocol designed to facilitate efficient interaction between AI models and applications. In the context of real-time data streaming, MCP provides a framework for:

  • Preserving context throughout the data pipeline
  • Standardizing data exchange formats
  • Optimizing the transmission of large datasets
  • Enhancing model-to-model and model-to-application communication
  • Core Components and Architecture

    MCP architecture for real-time streaming consists of several key components:

    1. Context Handlers: Manage and maintain contextual information across the streaming pipeline

    2. Stream Processors: Process incoming data streams using context-aware techniques

    3. Protocol Adapters: Convert between different streaming protocols while preserving context

    4. Context Store: Efficiently store and retrieve contextual information

    5. Streaming Connectors: Connect to various streaming platforms (Kafka, Pulsar, Kinesis, etc.)

    How MCP Improves Real-Time Data Handling

    MCP addresses traditional streaming challenges through:

  • Contextual Integrity: Maintaining relationships between data points across the entire pipeline
  • Optimized Transmission: Reducing redundancy in data exchange through intelligent context management
  • Standardized Interfaces: Providing consistent APIs for streaming components
  • Reduced Latency: Minimizing processing overhead through efficient context handling
  • Enhanced Scalability: Supporting horizontal scaling while preserving context
  • Integration and Implementation

    Real-time data streaming systems require careful architectural design and implementation to maintain both performance and contextual integrity.

    The Model Context Protocol offers a standardized approach to integrating AI models and streaming technologies, allowing for more sophisticated, context-aware processing pipelines.

    Overview of MCP Integration in Streaming Architectures

    Implementing MCP in real-time streaming environments involves several key considerations:

    1. Context Serialization and Transport: MCP provides efficient mechanisms for encoding contextual information within streaming data packets, ensuring that essential context follows the data throughout the processing pipeline.

    This includes standardized serialization formats optimized for streaming transport.

    2. Stateful Stream Processing: MCP enables more intelligent stateful processing by maintaining consistent context representation across processing nodes.

    This is particularly valuable in distributed streaming architectures where state management is traditionally challenging.

    3. Event-Time vs.

    Processing-Time: MCP implementations in streaming systems must address the common challenge of differentiating between when events occurred and when they're processed.

    The protocol can incorporate temporal context that preserves event time semantics.

    4. Backpressure Management: By standardizing context handling, MCP helps manage backpressure in streaming systems, allowing components to communicate their processing capabilities and adjust flow accordingly.

    5. Context Windowing and Aggregation: MCP facilitates more sophisticated windowing operations by providing structured representations of temporal and relational contexts, enabling more meaningful aggregations across event streams.

    6. Exactly-Once Processing: In streaming systems requiring exactly-once semantics, MCP can incorporate processing metadata to help track and verify processing status across distributed components.

    The implementation of MCP across various streaming technologies creates a unified approach to context management, reducing the need for custom integration code while enhancing the system's ability to maintain meaningful context as data flows through the pipeline.

    MCP in Various Data Streaming Frameworks

    These examples follow the current MCP specification which focuses on a JSON-RPC based protocol with distinct transport mechanisms.

    The code demonstrates how you can implement custom transports that integrate streaming platforms like Kafka and Pulsar while maintaining full compatibility with the MCP protocol.

    The examples are designed to show how streaming platforms can be integrated with MCP to provide real-time data processing while preserving the contextual awareness that is central to MCP.

    This approach ensures that the code samples accurately reflect the current state of the MCP specification as of June 2025.

    MCP can be integrated with popular streaming frameworks including:

    Overview

    Real-time web search has become essential in today's information-driven environment, where applications need immediate access to up-to-date information across the internet to provide relevant and timely responses.

    The Model Context Protocol (MCP) represents a significant advancement in optimizing these real-time search processes, enhancing search efficiency, maintaining contextual integrity, and improving overall system performance.

    This module explores how MCP transforms real-time web search by providing a standardized approach to context management across AI models, search engines, and applications.

    What You'll Learn

    In this comprehensive guide, you'll discover:

  • How MCP creates a seamless bridge between AI models and real-time web search capabilities
  • Architectural patterns for implementing efficient and scalable search solutions with MCP
  • Techniques for preserving search context across multiple queries and interactions
  • Practical code implementations in Python and JavaScript for various search scenarios
  • Methods to balance relevance, recency, and performance in MCP-powered search systems
  • Introduction to Real-Time Web Search

    Real-time web search is a technological approach that enables continuous querying, processing, and analysis of web-based information as it's published or updated, allowing systems to provide fresh and relevant information with minimal latency.

    Unlike traditional search systems that operate on indexed data which may be hours or days old, real-time search processes live data from the web, delivering insights and information that reflect the current state of online content.

    Core Concepts of Real-Time Web Search:

  • Continuous Query Processing: Search queries are processed against constantly updating data sources
  • Recency Prioritization: Systems are designed to prioritize fresh information
  • Relevance Balancing: Maintaining a balance between relevance and recency
  • Scalable Architecture: Systems must handle variable query loads and data volumes
  • Contextual Understanding: Maintaining user context across search iterations is crucial for meaningful results
  • Dynamic Query Reformulation: Adaptively modifying queries based on context and previous results
  • Multi-Source Integration: Combining results from multiple search providers and web sources
  • Semantic Understanding: Processing queries and content based on meaning rather than just keywords
  • Real-Time Ranking: Continuously adjusting result rankings as new information becomes available
  • The Model Context Protocol and Real-Time Web Search

    The Model Context Protocol (MCP) addresses several critical challenges in real-time web search environments:

    1. Search Context Preservation: MCP standardizes how context is maintained across distributed search components, ensuring that AI models and processing nodes have access to relevant query history and user preferences.

    2. Efficient Query Management: By providing structured mechanisms for context transmission, MCP reduces the overhead of repeating context in each search iteration.

    3. Interoperability: MCP creates a common language for context sharing between diverse search technologies and AI models, enabling more flexible and extensible architectures.

    4. Search-Optimized Context: MCP implementations can prioritize which context elements are most relevant for effective search, optimizing for both performance and accuracy.

    5. Adaptive Search Processing: With proper context management through MCP, search systems can dynamically adjust processing based on evolving user needs and information landscapes.

    In modern applications ranging from news aggregation to research assistants, the integration of MCP with web search technologies enables more intelligent, context-aware search that can provide increasingly relevant results as user interactions continue.

    How MCP Improves Real-Time Web Search

    MCP addresses traditional web search challenges through:

  • Contextual Continuity: Maintaining relationships between queries across the entire search session
  • Optimized Transmission: Reducing redundancy in search parameters through intelligent context management
  • Standardized Interfaces: Providing consistent APIs for search components
  • Reduced Latency: Minimizing processing overhead through efficient context handling
  • Enhanced Relevance: Improving search relevance by preserving user intent across multiple queries
  • Integration and Implementation

    Real-time web search systems require careful architectural design and implementation to maintain both performance and contextual integrity.

    The Model Context Protocol offers a standardized approach to integrating AI models and search technologies, allowing for more sophisticated, context-aware search pipelines.

    Overview of MCP Integration in Search Architectures

    Implementing MCP in real-time web search environments involves several key considerations:

    1. Search Context Serialization: MCP provides efficient mechanisms for encoding contextual information within search requests, ensuring that essential context follows the query throughout the processing pipeline.

    This includes standardized serialization formats optimized for search-related metadata.

    2. Stateful Search Processing: MCP enables more intelligent stateful processing by maintaining consistent context representation across search iterations.

    This is particularly valuable in multi-stage search pipelines where context refinement improves results.

    3. Query Expansion and Refinement: MCP implementations in search systems can facilitate sophisticated query expansion and refinement based on accumulated context, allowing for increasingly relevant results as the search session progresses.

    4. Result Caching and Prioritization: By standardizing context handling, MCP helps manage result caching and prioritization, allowing components to adapt based on the evolving search context.

    5. Search Federation and Aggregation: MCP facilitates more sophisticated federation of search across multiple backends by providing structured representations of search context, enabling more meaningful aggregation of results from diverse sources.

    The implementation of MCP across various search technologies creates a unified approach to context management, reducing the need for custom integration code while enhancing the system's ability to maintain meaningful context as search queries evolve.

    MCP in Various Web Search Implementations

    These examples follow the current MCP specification which focuses on a JSON-RPC based protocol with distinct transport mechanisms.

    The code demonstrates how you can implement custom search integrations while maintaining full compatibility with the MCP protocol.

    // connectToSearchServer().catch(console.error);

    Core Concepts

    The Model Context Protocol (MCP) Framework

    At its foundation, the Model Context Protocol provides a standardized way for AI models, applications, and services to exchange context.

    In real-time web search, this framework is essential for creating coherent, multi-turn search experiences.

    Key components include:

    1. Client-Server Architecture: MCP establishes a clear separation between search clients (requesters) and search servers (providers), allowing for flexible deployment models.

    2. JSON-RPC Communication: The protocol uses JSON-RPC for message exchange, making it compatible with web technologies and easy to implement across different platforms.

    3. Context Management: MCP defines structured methods for maintaining, updating, and leveraging search context across multiple interactions.

    4. Tool Definitions: Search capabilities are exposed as standardized tools with well-defined parameters and return values.

    5. Streaming Support: The protocol supports streaming results, essential for real-time search where results may arrive progressively.

    Web Search Integration Patterns

    When integrating MCP with web search, several patterns emerge:

    1. Direct Search Provider Integration
    
    graph LR
    
        Client[MCP Client] --> |MCP Request| Server[MCP Server]
    
        Server --> |API Call| SearchAPI[Search API]
    
        SearchAPI --> |Results| Server
    
        Server --> |MCP Response| Client
    
    

    In this pattern, the MCP server directly interfaces with one or more search APIs, translating MCP requests into API-specific calls and formatting the results as MCP responses.

    2. Federated Search with Context Preservation
    
    graph LR
    
        Client[MCP Client] --> |MCP Request| Federation[MCP Federation Layer]
    
        Federation --> |MCP Request 1| Search1[Search Provider 1]
    
        Federation --> |MCP Request 2| Search2[Search Provider 2]
    
        Federation --> |MCP Request 3| Search3[Search Provider 3]
    
        Search1 --> |MCP Response 1| Federation
    
        Search2 --> |MCP Response 2| Federation
    
        Search3 --> |MCP Response 3| Federation
    
        Federation --> |Aggregated MCP Response| Client
    
    

    This pattern distributes search queries across multiple MCP-compatible search providers, each potentially specializing in different types of content or search capabilities, while maintaining a unified context.

    3. Context-Enhanced Search Chain
    
    graph LR
    
        Client[MCP Client] --> |Query + Context| Server[MCP Server]
    
        Server --> |1. Query Analysis| NLP[NLP Service]
    
        NLP --> |Enhanced Query| Server
    
        Server --> |2. Search Execution| Search[Search Engine]
    
        Search --> |Raw Results| Server
    
        Server --> |3. Result Processing| Enhancement[Result Enhancement]
    
        Enhancement --> |Enhanced Results| Server
    
        Server --> |Final Results + Updated Context| Client
    
    

    In this pattern, the search process is divided into multiple stages, with context being enriched at each step, resulting in progressively more relevant results.

    Search Context Components

    In MCP-based web search, context typically includes:

  • Query History: Previous search queries in the session
  • User Preferences: Language, region, safe search settings
  • Interaction History: Which results were clicked, time spent on results
  • Search Parameters: Filters, sort orders, and other search modifiers
  • Domain Knowledge: Subject-specific context relevant to the search
  • Temporal Context: Time-based relevance factors
  • Source Preferences: Trusted or preferred information sources
  • Use Cases and Applications

    2. Data Privacy: Ensure appropriate handling of search queries and results, especially when they might contain sensitive information. Implement appropriate access controls to protect user data.

    3. Tool Safety: Implement proper authorization and validation for search tools, as they represent potential security risks through arbitrary code execution.

    Descriptions of tool behavior should be considered untrusted unless obtained from a trusted server.

    4. Clear Documentation: Provide clear documentation about the capabilities, limitations, and security considerations of your MCP-based search implementation, following the implementation guidelines from the MCP specification.

    5. Robust Consent Flows: Build robust consent and authorization flows that clearly explain what each tool does before authorizing its use, especially for tools that interact with external web resources.

    5.12 Entra ID Authentication for Model Context Protocol Servers

    Securing AI Workflows: Entra ID Authentication for Model Context Protocol Servers

    Introduction

    Securing your Model Context Protocol (MCP) server is as important as locking the front door of your house.

    Leaving your MCP server open exposes your tools and data to unauthorized access, which can lead to security breaches.

    Microsoft Entra ID provides a robust cloud-based identity and access management solution, helping ensure that only authorized users and applications can interact with your MCP server.

    In this section, you’ll learn how to protect your AI workflows using Entra ID authentication.

    Learning Objectives

    By the end of this section, you will be able to:

  • Understand the importance of securing MCP servers.
  • Explain the basics of Microsoft Entra ID and OAuth 2.0 authentication.
  • Recognize the difference between public and confidential clients.
  • Implement Entra ID authentication in both local (public client) and remote (confidential client) MCP server scenarios.
  • Apply security best practices when developing AI workflows.
  • Security and MCP

    Just as you wouldn't leave the front door of your house unlocked, you shouldn't leave your MCP server open for anyone to access.

    Securing your AI workflows is essential for building robust, trustworthy, and safe applications.

    This chapter will introduce you to using Microsoft Entra ID to secure your MCP servers, ensuring that only authorized users and applications can interact with your tools and data.

    Why Security Matters for MCP Servers

    Imagine your MCP server has a tool that can send emails or access a customer database. An unsecured server would mean anyone could potentially use that tool, leading to unauthorized data access, spam, or other malicious activities.

    By implementing authentication, you ensure that every request to your server is verified, confirming the identity of the user or application making the request. This is the first and most critical step in securing your AI workflows.

    Introduction to Microsoft Entra ID

    By using Entra ID, you can:

  • Enable secure sign-in for users.
  • Protect APIs and services.
  • Manage access policies from a central location.
  • For MCP servers, Entra ID provides a robust and widely-trusted solution to manage who can access your server's capabilities.

    Understanding the Magic: How Entra ID Authentication Works

    Entra ID uses open standards like OAuth 2.0 to handle authentication. While the details can be complex, the core concept is simple and can be understood with an analogy.

    A Gentle Introduction to OAuth 2.0: The Valet Key

    Think of OAuth 2.0 like a valet service for your car.

    When you arrive at a restaurant, you don't give the valet your master key.

    Instead, you provide a valet key that has limited permissions—it can start the car and lock the doors, but it can't open the trunk or the glove compartment.

    In this analogy:

  • You are the User.
  • Your car is the MCP Server with its valuable tools and data.
  • The Valet is Microsoft Entra ID.
  • The Parking Attendant is the MCP Client (the application trying to access the server).
  • The Valet Key is the Access Token.
  • The access token is a secure string of text that the MCP client receives from Entra ID after you sign in.

    The client then presents this token to the MCP server with every request.

    The server can verify the token to ensure the request is legitimate and that the client has the necessary permissions, all without ever needing to handle your actual credentials (like your password).

    The Authentication Flow

    Here’s how the process works in practice:

    
    sequenceDiagram
    
        actor User as 👤 User
    
        participant Client as 🖥️ MCP Client
    
        participant Entra as 🔐 Microsoft Entra ID
    
        participant Server as 🔧 MCP Server
    
    
    
        Client->>+User: Please sign in to continue.
    
        User->>+Entra: Enters credentials (username/password).
    
        Entra-->>Client: Here is your access token.
    
        User-->>-Client: (Returns to the application)
    
    
    
        Client->>+Server: I need to use a tool. Here is my access token.
    
        Server->>+Entra: Is this access token valid?
    
        Entra-->>-Server: Yes, it is.
    
        Server-->>-Client: Token is valid. Here is the result of the tool.
    
    

    Introducing the Microsoft Authentication Library (MSAL)

    Before we dive into the code, it's important to introduce a key component you'll see in the examples: the Microsoft Authentication Library (MSAL).

    MSAL is a library developed by Microsoft that makes it much easier for developers to handle authentication.

    Instead of you having to write all the complex code to handle security tokens, manage sign-ins, and refresh sessions, MSAL takes care of the heavy lifting.

    Using a library like MSAL is highly recommended because:

  • It's Secure: It implements industry-standard protocols and security best practices, reducing the risk of vulnerabilities in your code.
  • It Simplifies Development: It abstracts away the complexity of the OAuth 2.0 and OpenID Connect protocols, allowing you to add robust authentication to your application with just a few lines of code.
  • It's Maintained: Microsoft actively maintains and updates MSAL to address new security threats and platform changes.
  • MSAL supports a wide variety of languages and application frameworks, including .NET, JavaScript/TypeScript, Python, Java, Go, and mobile platforms like iOS and Android.

    This means you can use the same consistent authentication patterns across your entire technology stack.

    To learn more about MSAL, you can check out the official MSAL overview documentation.

    Securing Your MCP Server with Entra ID: A Step-by-Step Guide

    Now, let's walk through how to secure a local MCP server (one that communicates over stdio) using Entra ID.

    This example uses a public client, which is suitable for applications running on a user's machine, like a desktop app or a local development server.

    Scenario 1: Securing a Local MCP Server (with a Public Client)

    In this scenario, we'll look at an MCP server that runs locally, communicates over stdio, and uses Entra ID to authenticate the user before allowing access to its tools.

    The server will have a single tool that fetches the user's profile information from the Microsoft Graph API.

    1. Setting Up the Application in Entra ID

    Before writing any code, you need to register your application in Microsoft Entra ID. This tells Entra ID about your application and grants it permission to use the authentication service.

    1. Navigate to the Microsoft Entra portal.

    2. Go to App registrations and click New registration.

    3. Give your application a name (e.g., "My Local MCP Server").

    4. For Supported account types, select Accounts in this organizational directory only.

    5. You can leave the Redirect URI blank for this example.

    6. Click Register.

    Once registered, take note of the Application (client) ID and Directory (tenant) ID. You'll need these in your code.

    2. The Code: A Breakdown

    Let's look at the key parts of the code that handle authentication.

    The full code for this example is available in the Entra ID - Local - WAM folder of the mcp-auth-servers GitHub repository.

    AuthenticationService.cs

    This class is responsible for handling the interaction with Entra ID.

  • CreateAsync: This method initializes the PublicClientApplication from the MSAL (Microsoft Authentication Library). It's configured with your application's clientId and tenantId.
  • WithBroker: This enables the use of a broker (like the Windows Web Account Manager), which provides a more secure and seamless single sign-on experience.
  • AcquireTokenAsync: This is the core method. It first tries to get a token silently (meaning the user won't have to sign in again if they already have a valid session). If a silent token can't be acquired, it will prompt the user to sign in interactively.
  • 
    // Simplified for clarity
    
    public static async Task<AuthenticationService> CreateAsync(ILogger<AuthenticationService> logger)
    
    {
    
        var msalClient = PublicClientApplicationBuilder
    
            .Create(_clientId) // Your Application (client) ID
    
            .WithAuthority(AadAuthorityAudience.AzureAdMyOrg)
    
            .WithTenantId(_tenantId) // Your Directory (tenant) ID
    
            .WithBroker(new BrokerOptions(BrokerOptions.OperatingSystems.Windows))
    
            .Build();
    
    
    
        // ... cache registration ...
    
    
    
        return new AuthenticationService(logger, msalClient);
    
    }
    
    
    
    public async Task<string> AcquireTokenAsync()
    
    {
    
        try
    
        {
    
            // Try silent authentication first
    
            var accounts = await _msalClient.GetAccountsAsync();
    
            var account = accounts.FirstOrDefault();
    
    
    
            AuthenticationResult? result = null;
    
    
    
            if (account != null)
    
            {
    
                result = await _msalClient.AcquireTokenSilent(_scopes, account).ExecuteAsync();
    
            }
    
            else
    
            {
    
                // If no account, or silent fails, go interactive
    
                result = await _msalClient.AcquireTokenInteractive(_scopes).ExecuteAsync();
    
            }
    
    
    
            return result.AccessToken;
    
        }
    
        catch (Exception ex)
    
        {
    
            _logger.LogError(ex, "An error occurred while acquiring the token.");
    
            throw; // Optionally rethrow the exception for higher-level handling
    
        }
    
    }
    
    

    Program.cs

    This is where the MCP server is set up and the authentication service is integrated.

  • AddSingleton: This registers the AuthenticationService with the dependency injection container, so it can be used by other parts of the application (like our tool).
  • GetUserDetailsFromGraph tool: This tool requires an instance of AuthenticationService. Before it does anything, it calls authService.AcquireTokenAsync() to get a valid access token. If authentication is successful, it uses the token to call the Microsoft Graph API and fetch the user's details.
  • 
    // Simplified for clarity
    
    [McpServerTool(Name = "GetUserDetailsFromGraph")]
    
    public static async Task<string> GetUserDetailsFromGraph(
    
        AuthenticationService authService)
    
    {
    
        try
    
        {
    
            // This will trigger the authentication flow
    
            var accessToken = await authService.AcquireTokenAsync();
    
    
    
            // Use the token to create a GraphServiceClient
    
            var graphClient = new GraphServiceClient(
    
                new BaseBearerTokenAuthenticationProvider(new TokenProvider(authService)));
    
    
    
            var user = await graphClient.Me.GetAsync();
    
    
    
            return System.Text.Json.JsonSerializer.Serialize(user);
    
        }
    
        catch (Exception ex)
    
        {
    
            return $"Error: {ex.Message}";
    
        }
    
    }
    
    
    3. How It All Works Together

    1.

    When the MCP client tries to use the GetUserDetailsFromGraph tool, the tool first calls AcquireTokenAsync.

    2. AcquireTokenAsync triggers the MSAL library to check for a valid token.

    3. If no token is found, MSAL, through the broker, will prompt the user to sign in with their Entra ID account.

    4. Once the user signs in, Entra ID issues an access token.

    5. The tool receives the token and uses it to make a secure call to the Microsoft Graph API.

    6. The user's details are returned to the MCP client.

    This process ensures that only authenticated users can use the tool, effectively securing your local MCP server.

    Scenario 2: Securing a Remote MCP Server (with a Confidential Client)

    When your MCP server is running on a remote machine (like a cloud server) and communicates over a protocol like HTTP Streaming, the security requirements are different.

    In this case, you should use a confidential client and the Authorization Code Flow.

    This is a more secure method because the application's secrets are never exposed to the browser.

    This example uses a TypeScript-based MCP server that uses Express.js to handle HTTP requests.

    1. Setting Up the Application in Entra ID

    The setup in Entra ID is similar to the public client, but with one key difference: you need to create a client secret.

    1. Navigate to the Microsoft Entra portal.

    2. In your app registration, go to the Certificates & secrets tab.

    3. Click New client secret, give it a description, and click Add.

    4. Important: Copy the secret value immediately. You will not be able to see it again.

    5.

    You also need to configure a Redirect URI.

    Go to the Authentication tab, click Add a platform, select Web, and enter the redirect URI for your application (e.g., http://localhost:3001/auth/callback).

    > ⚠️ Important Security Note: For production applications, Microsoft strongly recommends using secretless authentication methods such as Managed Identity or Workload Identity Federation instead of client secrets.

    Client secrets pose security risks as they can be exposed or compromised.

    Managed identities provide a more secure approach by eliminating the need to store credentials in your code or configuration.

    >

    > For more information about managed identities and how to implement them, see the Managed identities for Azure resources overview.

    2. The Code: A Breakdown

    This example uses a session-based approach.

    When the user authenticates, the server stores the access token and refresh token in a session and gives the user a session token.

    This session token is then used for subsequent requests.

    The full code for this example is available in the Entra ID - Confidential client folder of the mcp-auth-servers GitHub repository.

    Server.ts

    This file sets up the Express server and the MCP transport layer.

  • requireBearerAuth: This is middleware that protects the /sse and /message endpoints. It checks for a valid bearer token in the Authorization header of the request.
  • EntraIdServerAuthProvider: This is a custom class that implements the McpServerAuthorizationProvider interface. It's responsible for handling the OAuth 2.0 flow.
  • /auth/callback: This endpoint handles the redirect from Entra ID after the user has authenticated. It exchanges the authorization code for an access token and a refresh token.
  • 
    // Simplified for clarity
    
    const app = express();
    
    const { server } = createServer();
    
    const provider = new EntraIdServerAuthProvider();
    
    
    
    // Protect the SSE endpoint
    
    app.get("/sse", requireBearerAuth({
    
      provider,
    
      requiredScopes: ["User.Read"]
    
    }), async (req, res) => {
    
      // ... connect to the transport ...
    
    });
    
    
    
    // Protect the message endpoint
    
    app.post("/message", requireBearerAuth({
    
      provider,
    
      requiredScopes: ["User.Read"]
    
    }), async (req, res) => {
    
      // ... handle the message ...
    
    });
    
    
    
    // Handle the OAuth 2.0 callback
    
    app.get("/auth/callback", (req, res) => {
    
      provider.handleCallback(req.query.code, req.query.state)
    
        .then(result => {
    
          // ... handle success or failure ...
    
        });
    
    });
    
    

    Tools.ts

    This file defines the tools that the MCP server provides.

    The getUserDetails tool is similar to the one in the previous example, but it gets the access token from the session.

    
    // Simplified for clarity
    
    server.setRequestHandler(CallToolRequestSchema, async (request) => {
    
      const { name } = request.params;
    
      const context = request.params?.context as { token?: string } | undefined;
    
      const sessionToken = context?.token;
    
    
    
      if (name === ToolName.GET_USER_DETAILS) {
    
        if (!sessionToken) {
    
          throw new AuthenticationError("Authentication token is missing or invalid. Ensure the token is provided in the request context.");
    
        }
    
    
    
        // Get the Entra ID token from the session store
    
        const tokenData = tokenStore.getToken(sessionToken);
    
        const entraIdToken = tokenData.accessToken;
    
    
    
        const graphClient = Client.init({
    
          authProvider: (done) => {
    
            done(null, entraIdToken);
    
          }
    
        });
    
    
    
        const user = await graphClient.api('/me').get();
    
    
    
        // ... return user details ...
    
      }
    
    });
    
    

    auth/EntraIdServerAuthProvider.ts

    This class handles the logic for:

  • Redirecting the user to the Entra ID sign-in page.
  • Exchanging the authorization code for an access token.
  • Storing the tokens in the tokenStore.
  • Refreshing the access token when it expires.
  • 3. How It All Works Together

    1.

    When a user first tries to connect to the MCP server, the requireBearerAuth middleware will see that they don't have a valid session and will redirect them to the Entra ID sign-in page.

    2. The user signs in with their Entra ID account.

    3. Entra ID redirects the user back to the /auth/callback endpoint with an authorization code.

    4. The server exchanges the code for an access token and a refresh token, stores them, and creates a session token which is sent to the client.

    5. The client can now use this session token in the Authorization header for all future requests to the MCP server.

    6. When the getUserDetails tool is called, it uses the session token to look up the Entra ID access token and then uses that to call the Microsoft Graph API.

    This flow is more complex than the public client flow, but is required for internet-facing endpoints.

    Since remote MCP servers are accessible over the public internet, they need stronger security measures to protect against unauthorized access and potential attacks.

    Security Best Practices

  • Always use HTTPS: Encrypt communication between the client and server to protect tokens from being intercepted.
  • Implement Role-Based Access Control (RBAC): Don't just check *if* a user is authenticated; check *what* they are authorized to do. You can define roles in Entra ID and check for them in your MCP server.
  • Monitor and audit: Log all authentication events so you can detect and respond to suspicious activity.
  • Handle rate limiting and throttling: Microsoft Graph and other APIs implement rate limiting to prevent abuse. Implement exponential backoff and retry logic in your MCP server to gracefully handle HTTP 429 (Too Many Requests) responses. Consider caching frequently accessed data to reduce API calls.
  • Secure token storage: Store access tokens and refresh tokens securely. For local applications, use the system's secure storage mechanisms. For server applications, consider using encrypted storage or secure key management services like Azure Key Vault.
  • Token expiration handling: Access tokens have a limited lifetime. Implement automatic token refresh using refresh tokens to maintain seamless user experience without requiring re-authentication.
  • Consider using Azure API Management: While implementing security directly in your MCP server gives you fine-grained control, API Gateways like Azure API Management can handle many of these security concerns automatically, including authentication, authorization, rate limiting, and monitoring. They provide a centralized security layer that sits between your clients and your MCP servers. For more details on using API Gateways with MCP, see our Azure API Management Your Auth Gateway For MCP Servers.

    MCP Tool Configuration Options

    When configuring MCP tools for your agent, you can specify several important parameters:

    Python Configuration

    
    mcp_tool = McpTool(
    
        server_label="unique_server_name",      # Identifier for the MCP server
    
        server_url="https://api.example.com/mcp", # MCP server endpoint
    
        allowed_tools=[],                       # Optional: specify allowed tools
    
    )
    
    

    .NET Configuration

    
    MCPToolDefinition mcpTool = new(
    
        "unique_server_name",                   // Server label
    
        "https://api.example.com/mcp"          // MCP server URL
    
    );
    
    

    Authentication and Headers

    Both implementations support custom headers for authentication:

    Python

    
    mcp_tool.update_headers("SuperSecret", "123456")
    
    

    .NET

    
    MCPToolResource mcpToolResource = new(mcpServerLabel);

    Context Engineering: An Emerging Concept in the MCP Ecosystem

    Overview

    Context engineering is an emerging concept in the AI space that explores how information is structured, delivered, and maintained throughout interactions between clients and AI services.

    As the Model Context Protocol (MCP) ecosystem evolves, understanding how to effectively manage context becomes increasingly important.

    This module introduces the concept of context engineering and explores its potential applications in MCP implementations.

    Learning Objectives

    By the end of this module, you will be able to:

  • Understand the emerging concept of context engineering and its potential role in MCP applications
  • Identify key challenges in context management that the MCP protocol design addresses
  • Explore techniques for improving model performance through better context handling
  • Consider approaches to measure and evaluate context effectiveness
  • Apply these emerging concepts to improve AI experiences through the MCP framework
  • Introduction to Context Engineering

    Context engineering is an emerging concept focused on the deliberate design and management of information flow between users, applications, and AI models.

    Unlike established fields such as prompt engineering, context engineering is still being defined by practitioners as they work to solve the unique challenges of providing AI models with the right information at the right time.

    As large language models (LLMs) have evolved, the importance of context has become increasingly apparent.

    The quality, relevance, and structure of the context we provide directly impacts model outputs.

    Context engineering explores this relationship and seeks to develop principles for effective context management.

    > "In 2025, the models out there are extremely intelligent.

    But even the smartest human won't be able to do their job effectively without the context of what they're being asked to do... 'Context engineering' is the next level of prompt engineering.

    It is about doing this automatically in a dynamic system." — Walden Yan, Cognition AI

    Context engineering might encompass:

    1. Context Selection: Determining what information is relevant for a given task

    2. Context Structuring: Organizing information to maximize model comprehension

    3. Context Delivery: Optimizing how and when information is sent to models

    4. Context Maintenance: Managing state and evolution of context over time

    5. Context Evaluation: Measuring and improving the effectiveness of context

    These areas of focus are particularly relevant to the MCP ecosystem, which provides a standardized way for applications to provide context to LLMs.

    The Context Journey Perspective

    One way to visualize context engineering is to trace the journey information takes through an MCP system:

    
    graph LR
    
        A[User Input] --> B[Context Assembly]
    
        B --> C[Model Processing]
    
        C --> D[Response Generation]
    
        D --> E[State Management]
    
        E -->|Next Interaction| A
    
        
    
        style A fill:#A8D5BA,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style B fill:#7FB3D5,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style C fill:#F5CBA7,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style D fill:#C39BD3,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style E fill:#F9E79F,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
    

    Key Stages in the Context Journey:

    1. User Input: Raw information from the user (text, images, documents)

    2. Context Assembly: Combining user input with system context, conversation history, and other retrieved information

    3. Model Processing: The AI model processes the assembled context

    4. Response Generation: The model produces outputs based on the provided context

    5. State Management: The system updates its internal state based on the interaction

    This perspective highlights the dynamic nature of context in AI systems and raises important questions about how to best manage information at each stage.

    Emerging Principles in Context Engineering

    As the field of context engineering takes shape, some early principles are beginning to emerge from practitioners. These principles may help inform MCP implementation choices:

    Principle 1: Share Context Completely

    Context should be shared completely between all components of a system rather than fragmented across multiple agents or processes. When context is distributed, decisions made in one part of the system may conflict with those made elsewhere.

    
    graph TD
    
        subgraph "Fragmented Context Approach"
    
        A1[Agent 1] --- C1[Context 1]
    
        A2[Agent 2] --- C2[Context 2]
    
        A3[Agent 3] --- C3[Context 3]
    
        end
    
        
    
        subgraph "Unified Context Approach"
    
        B1[Agent] --- D1[Shared Complete Context]
    
        end
    
        
    
        style A1 fill:#AED6F1,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style A2 fill:#AED6F1,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style A3 fill:#AED6F1,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style B1 fill:#A9DFBF,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style C1 fill:#F5B7B1,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style C2 fill:#F5B7B1,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style C3 fill:#F5B7B1,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style D1 fill:#D7BDE2,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
    

    In MCP applications, this suggests designing systems where context flows seamlessly through the entire pipeline rather than being compartmentalized.

    Principle 2: Recognize That Actions Carry Implicit Decisions

    Each action a model takes embodies implicit decisions about how to interpret the context. When multiple components act on different contexts, these implicit decisions can conflict, leading to inconsistent outcomes.

    This principle has important implications for MCP applications:

  • Prefer linear processing of complex tasks over parallel execution with fragmented context
  • Ensure that all decision points have access to the same contextual information
  • Design systems where later steps can see the full context of earlier decisions
  • Principle 3: Balance Context Depth with Window Limitations

    As conversations and processes grow longer, context windows eventually overflow. Effective context engineering explores approaches to manage this tension between comprehensive context and technical limitations.

    Potential approaches being explored include:

  • Context compression that maintains essential information while reducing token usage
  • Progressive loading of context based on relevance to current needs
  • Summarization of previous interactions while preserving key decisions and facts
  • Context Challenges and MCP Protocol Design

    The Model Context Protocol (MCP) was designed with an awareness of the unique challenges of context management. Understanding these challenges helps explain key aspects of the MCP protocol design:

    Challenge 1: Context Window Limitations

    Most AI models have fixed context window sizes, limiting how much information they can process at once.

    MCP Design Response:

  • The protocol supports structured, resource-based context that can be referenced efficiently
  • Resources can be paginated and loaded progressively
  • Challenge 2: Relevance Determination

    Determining which information is most relevant to include in context is difficult.

    MCP Design Response:

  • Flexible tooling allows dynamic retrieval of information based on need
  • Structured prompts enable consistent context organization
  • Challenge 3: Context Persistence

    Managing state across interactions requires careful tracking of context.

    MCP Design Response:

  • Standardized session management
  • Clearly defined interaction patterns for context evolution
  • Challenge 4: Multi-Modal Context

    Different types of data (text, images, structured data) require different handling.

    MCP Design Response:

  • Protocol design accommodates various content types
  • Standardized representation of multi-modal information
  • Challenge 5: Security and Privacy

    Context often contains sensitive information that must be protected.

    MCP Design Response:

  • Clear boundaries between client and server responsibilities
  • Local processing options to minimize data exposure
  • Understanding these challenges and how MCP addresses them provides a foundation for exploring more advanced context engineering techniques.

    Emerging Context Engineering Approaches

    As the field of context engineering develops, several promising approaches are emerging. These represent current thinking rather than established best practices, and will likely evolve as we gain more experience with MCP implementations.

    1. Single-Threaded Linear Processing

    In contrast to multi-agent architectures that distribute context, some practitioners are finding that single-threaded linear processing produces more consistent results. This aligns with the principle of maintaining unified context.

    
    graph TD
    
        A[Task Start] --> B[Process Step 1]
    
        B --> C[Process Step 2]
    
        C --> D[Process Step 3]
    
        D --> E[Result]
    
        
    
        style A fill:#A9CCE3,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style B fill:#A3E4D7,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style C fill:#F9E79F,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style D fill:#F5CBA7,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style E fill:#D2B4DE,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
    

    While this approach may seem less efficient than parallel processing, it often produces more coherent and reliable results because each step builds on a complete understanding of previous decisions.

    2. Context Chunking and Prioritization

    Breaking large contexts into manageable pieces and prioritizing what's most important.

    
    # Conceptual Example: Context Chunking and Prioritization
    
    def process_with_chunked_context(documents, query):
    
        # 1. Break documents into smaller chunks
    
        chunks = chunk_documents(documents)
    
        
    
        # 2. Calculate relevance scores for each chunk
    
        scored_chunks = [(chunk, calculate_relevance(chunk, query)) for chunk in chunks]
    
        
    
        # 3. Sort chunks by relevance score
    
        sorted_chunks = sorted(scored_chunks, key=lambda x: x[1], reverse=True)
    
        
    
        # 4. Use the most relevant chunks as context
    
        context = create_context_from_chunks([chunk for chunk, score in sorted_chunks[:5]])
    
        
    
        # 5. Process with the prioritized context
    
        return generate_response(context, query)
    
    

    The concept above illustrates how we might break large documents into manageable pieces and select only the most relevant parts for context. This approach can help work within context window limitations while still leveraging large knowledge bases.

    3. Progressive Context Loading

    Loading context progressively as needed rather than all at once.

    
    sequenceDiagram
    
        participant User
    
        participant App

        App->>MCP Server: Initial Request
    
        MCP Server->>AI Model: Minimal Context
    
        AI Model->>MCP Server: Initial Response
    
        
    
        alt Needs More Context
    
            MCP Server->>MCP Server: Identify Missing Context
    
            MCP Server->>MCP Server: Load Additional Context
    
            MCP Server->>AI Model: Enhanced Context
    
            AI Model->>MCP Server: Final Response
    
        end
    
        
    
        MCP Server->>App: Response
    
        App->>User: Answer
    
    

    Progressive context loading starts with minimal context and expands only when necessary. This can significantly reduce token usage for simple queries while maintaining the ability to handle complex questions.

    4. Context Compression and Summarization

    Reducing context size while preserving essential information.

    
    graph TD
    
        A[Full Context] --> B[Compression Model]
    
        B --> C[Compressed Context]
    
        C --> D[Main Processing Model]
    
        D --> E[Response]
    
        
    
        style A fill:#A9CCE3,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style B fill:#A3E4D7,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style C fill:#F5CBA7,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style D fill:#D2B4DE,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style E fill:#F9E79F,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
    

    Context compression focuses on:

  • Removing redundant information
  • Summarizing lengthy content
  • Extracting key facts and details
  • Preserving critical context elements
  • Optimizing for token efficiency
  • This approach can be particularly valuable for maintaining long conversations within context windows or for processing large documents efficiently.

    Some practitioners are using specialized models specifically for context compression and summarization of conversation history.

    Exploratory Context Engineering Considerations

    As we explore the emerging field of context engineering, several considerations are worth keeping in mind when working with MCP implementations.

    These are not prescriptive best practices but rather areas of exploration that may yield improvements in your specific use case.

    Consider Your Context Goals

    Before implementing complex context management solutions, clearly articulate what you're trying to achieve:

  • What specific information does the model need to be successful?
  • Which information is essential versus supplementary?
  • What are your performance constraints (latency, token limits, costs)?
  • Explore Layered Context Approaches

    Some practitioners are finding success with context arranged in conceptual layers:

  • Core Layer: Essential information the model always needs
  • Situational Layer: Context specific to the current interaction
  • Supporting Layer: Additional information that may be helpful
  • Fallback Layer: Information accessed only when needed
  • Investigate Retrieval Strategies

    The effectiveness of your context often depends on how you retrieve information:

  • Semantic search and embeddings for finding conceptually relevant information
  • Keyword-based search for specific factual details
  • Hybrid approaches that combine multiple retrieval methods
  • Metadata filtering to narrow scope based on categories, dates, or sources
  • Experiment with Context Coherence

    The structure and flow of your context may affect model comprehension:

  • Grouping related information together
  • Using consistent formatting and organization
  • Maintaining logical or chronological ordering where appropriate
  • Avoiding contradictory information
  • Weigh the Tradeoffs of Multi-Agent Architectures

    While multi-agent architectures are popular in many AI frameworks, they come with significant challenges for context management:

  • Context fragmentation can lead to inconsistent decisions across agents
  • Parallel processing may introduce conflicts that are difficult to reconcile
  • Communication overhead between agents can offset performance gains
  • Complex state management is required to maintain coherence
  • In many cases, a single-agent approach with comprehensive context management may produce more reliable results than multiple specialized agents with fragmented context.

    Develop Evaluation Methods

    To improve context engineering over time, consider how you'll measure success:

  • A/B testing different context structures
  • Monitoring token usage and response times
  • Tracking user satisfaction and task completion rates
  • Analyzing when and why context strategies fail
  • These considerations represent active areas of exploration in the context engineering space. As the field matures, more definitive patterns and practices will likely emerge.

    Measuring Context Effectiveness: An Evolving Framework

    As context engineering emerges as a concept, practitioners are beginning to explore how we might measure its effectiveness. No established framework exists yet, but various metrics are being considered that could help guide future work.

    Potential Measurement Dimensions

    1. Input Efficiency Considerations
  • Context-to-Response Ratio: How much context is needed relative to the response size?
  • Token Utilization: What percentage of provided context tokens appear to influence the response?
  • Context Reduction: How effectively might we compress raw information?
  • 2. Performance Considerations
  • Latency Impact: How does context management affect response time?
  • Token Economy: Are we optimizing token usage effectively?
  • Retrieval Precision: How relevant is the retrieved information?
  • Resource Utilization: What computational resources are required?
  • 3. Quality Considerations
  • Response Relevance: How well does the response address the query?
  • Factual Accuracy: Does context management improve factual correctness?
  • Consistency: Are responses consistent across similar queries?
  • Hallucination Rate: Does better context reduce model hallucinations?
  • 4. User Experience Considerations
  • Follow-up Rate: How often do users need clarification?
  • Task Completion: Do users successfully accomplish their goals?
  • Satisfaction Indicators: How do users rate their experience?
  • Exploratory Approaches to Measurement

    When experimenting with context engineering in MCP implementations, consider these exploratory approaches:

    1. Baseline Comparisons: Establish a baseline with simple context approaches before testing more sophisticated methods

    2. Incremental Changes: Change one aspect of context management at a time to isolate its effects

    3. User-Centered Evaluation: Combine quantitative metrics with qualitative user feedback

    4. Failure Analysis: Examine cases where context strategies fail to understand potential improvements

    5. Multi-Dimensional Assessment: Consider trade-offs between efficiency, quality, and user experience

    This experimental, multi-faceted approach to measurement aligns with the emerging nature of context engineering.

    Closing Thoughts

    Context engineering is an emerging area of exploration that may prove central to effective MCP applications.

    By thoughtfully considering how information flows through your system, you can potentially create AI experiences that are more efficient, accurate, and valuable to users.

    The techniques and approaches outlined in this module represent early thinking in this space, not established practices.

    Context engineering may develop into a more defined discipline as AI capabilities evolve and our understanding deepens.

    For now, experimentation combined with careful measurement seems to be the most productive approach.

    Potential Future Directions

    The field of context engineering is still in its early stages, but several promising directions are emerging:

  • Context engineering principles may significantly impact model performance, efficiency, user experience, and reliability
  • Single-threaded approaches with comprehensive context management may outperform multi-agent architectures for many use cases
  • Specialized context compression models may become standard components in AI pipelines
  • The tension between context completeness and token limitations will likely drive innovation in context handling
  • As models become more capable at efficient human-like communication, true multi-agent collaboration may become more viable
  • MCP implementations may evolve to standardize context management patterns that emerge from current experimentation

    MCP Custom Transports - Advanced Implementation Guide

    The Model Context Protocol (MCP) provides flexibility in transport mechanisms, allowing custom implementations for specialized enterprise environments.

    This advanced guide explores custom transport implementations using Azure Event Grid and Azure Event Hubs as practical examples for building scalable, cloud-native MCP solutions.

    Introduction

    While MCP's standard transports (stdio and HTTP streaming) serve most use cases, enterprise environments often require specialized transport mechanisms for improved scalability, reliability, and integration with existing cloud infrastructure.

    Custom transports enable MCP to leverage cloud-native messaging services for asynchronous communication, event-driven architectures, and distributed processing.

    This lesson explores advanced transport implementations based on the latest MCP specification (2025-11-25), Azure messaging services, and established enterprise integration patterns.

    MCP Transport Architecture

    From MCP Specification (2025-11-25):

  • Standard Transports: stdio (recommended), HTTP streaming (for remote scenarios)
  • Custom Transports: Any transport that implements the MCP message exchange protocol
  • Message Format: JSON-RPC 2.0 with MCP-specific extensions
  • Bidirectional Communication: Full duplex communication required for notifications and responses
  • Learning Objectives

    By the end of this advanced lesson, you will be able to:

  • Understand Custom Transport Requirements: Implement MCP protocol over any transport layer while maintaining compliance
  • Build Azure Event Grid Transport: Create event-driven MCP servers using Azure Event Grid for serverless scalability
  • Implement Azure Event Hubs Transport: Design high-throughput MCP solutions using Azure Event Hubs for real-time streaming

    Message Durability and Reliability

    
    // Implementing message durability with retry logic
    
    public class ReliableTransportWrapper : IMcpTransport
    
    {
    
        private readonly IMcpTransport _innerTransport;
    
        private readonly RetryPolicy _retryPolicy;

            });
    
        }
    
    }
    
    

    Transport Security Integration

    
    // Integrating Azure Key Vault for transport security
    
    public class SecureTransportFactory
    
    {
    
        private readonly SecretClient _keyVaultClient;

            return new EventGridMcpTransport(
    
                topicEndpoint.Value.Value,
    
                accessKey.Value.Value,
    
                Environment.MachineName
    
            );
    
        }
    
    }
    
    

    Transport Monitoring and Observability

    
    // Adding telemetry to custom transports
    
    public class ObservableTransport : IMcpTransport
    
    {
    
        private readonly IMcpTransport _transport;
    
        private readonly ILogger _logger;

            var stopwatch = Stopwatch.StartNew();
    
            
    
            try
    
            {

    }
    
    

    Enterprise Integration Scenarios

    Scenario 1: Distributed MCP Processing

    Using Azure Event Grid for distributing MCP requests across multiple processing nodes:

    
    Architecture:
    
      - MCP Client sends requests to Event Grid topic
    
      - Multiple Azure Functions subscribe to process different tool types
    
      - Results aggregated and returned via separate response topic
    
      
    
    Benefits:
    
      - Horizontal scaling based on message volume
    
      - Fault tolerance through redundant processors
    
      - Cost optimization with serverless compute
    
    

    Scenario 2: Real-time MCP Streaming

    Using Azure Event Hubs for high-frequency MCP interactions:

    
    Architecture:
    
      - MCP Client streams continuous requests via Event Hubs
    
      - Stream Analytics processes and routes messages
    
      - Multiple consumers handle different aspect of processing
    
      
    
    Benefits:
    
      - Low latency for real-time scenarios
    
      - High throughput for batch processing
    
      - Built-in partitioning for parallel processing
    
    

    Scenario 3: Hybrid Transport Architecture

    Combining multiple transports for different use cases:

    
    public class HybridMcpTransport : IMcpTransport
    
    {
    
        private readonly IMcpTransport _realtimeTransport; // Event Hubs
    
        private readonly IMcpTransport _batchTransport;    // Event Grid
    
        private readonly IMcpTransport _fallbackTransport; // HTTP Streaming
    
        
    
        public async Task SendMessageAsync(McpMessage message)
    
        {
    
            // Route based on message characteristics
    
            var transport = message.Method switch
    
            {
    
                "tools/call" when IsRealtime(message) => _realtimeTransport,
    
                "resources/read" when IsBatch(message) => _batchTransport,
    
                _ => _fallbackTransport
    
            };
    
            
    
            await transport.SendMessageAsync(message);
    
        }
    
    }
    
    

    Performance Optimization

    Message Batching for Event Grid

    
    public class BatchingEventGridTransport : IMcpTransport
    
    {
    
        private readonly List<McpMessage> _messageBuffer = new();
    
        private readonly Timer _flushTimer;
    
        private const int MaxBatchSize = 100;
    
        
    
        public async Task SendMessageAsync(McpMessage message)
    
        {
    
            lock (_messageBuffer)
    
            {
    
                _messageBuffer.Add(message);
    
                
    
                if (_messageBuffer.Count >= MaxBatchSize)
    
                {
    
                    _ = Task.Run(FlushMessages);
    
                }
    
            }
    
        }
    
        
    
        private async Task FlushMessages()
    
        {
    
            List<McpMessage> toSend;
    
            lock (_messageBuffer)
    
            {
    
                toSend = new List<McpMessage>(_messageBuffer);
    
                _messageBuffer.Clear();
    
            }
    
            
    
            if (toSend.Any())
    
            {
    
                var events = toSend.Select(CreateEventGridEvent);
    
                await _publisher.SendEventsAsync(events);
    
            }
    
        }
    
    }
    
    

    Partitioning Strategy for Event Hubs

    
    public class PartitionedEventHubsTransport : IMcpTransport
    
    {
    
        public async Task SendMessageAsync(McpMessage message)
    
        {
    
            // Partition by client ID for session affinity
    
            var partitionKey = ExtractClientId(message);
    
            
    
            var eventData = new EventData(JsonSerializer.SerializeToUtf8Bytes(message))
    
            {
    
                PartitionKey = partitionKey
    
            };
    
            
    
            await _producer.SendAsync(new[] { eventData });
    
        }
    
    }
    
    

    Testing Custom Transports

    Unit Testing with Test Doubles

    
    [Test]
    
    public async Task EventGridTransport_SendMessage_PublishesCorrectEvent()
    
    {
    
        // Arrange
    
        var mockPublisher = new Mock<EventGridPublisherClient>();
    
        var transport = new EventGridMcpTransport(mockPublisher.Object);
    
        var message = new McpMessage { Method = "tools/list", Id = "test-123" };
    
        
    
        // Act
    
        await transport.SendMessageAsync(message);
    
        
    
        // Assert
    
        mockPublisher.Verify(
    
            x => x.SendEventAsync(
    
                It.Is<EventGridEvent>(e => 
    
                    e.EventType == "MCP.MessageReceived" &&
    
                    e.Subject == "mcp/test-client"
    
                )
    
            ),
    
            Times.Once
    
        );
    
    }
    
    

    Integration Testing with Azure Test Containers

    
    [Test]
    
    public async Task EventHubsTransport_IntegrationTest()
    
    {
    
        // Using Testcontainers for integration testing
    
        var eventHubsContainer = new EventHubsContainer()
    
            .WithEventHub("test-hub");
    
        
    
        await eventHubsContainer.StartAsync();
    
        
    
        var transport = new EventHubsMcpTransport(
    
            eventHubsContainer.GetConnectionString(),
    
            "test-hub"
    
        );
    
        
    
        // Test message round-trip
    
        var sentMessage = new McpMessage { Method = "test", Id = "123" };
    
        McpMessage receivedMessage = null;
    
        
    
        await transport.StartReceivingAsync(msg => {
    
            receivedMessage = msg;
    
            return Task.CompletedTask;
    
        });
    
        
    
        await transport.SendMessageAsync(sentMessage);
    
        await Task.Delay(1000); // Allow for message processing
    
        
    
        Assert.That(receivedMessage?.Id, Is.EqualTo("123"));
    
    }
    
    

    Best Practices and Guidelines

    Transport Design Principles

    1. Idempotency: Ensure message processing is idempotent to handle duplicates

    2. Error Handling: Implement comprehensive error handling and dead letter queues

    3. Monitoring: Add detailed telemetry and health checks

    4. Security: Use managed identities and least privilege access

    5. Performance: Design for your specific latency and throughput requirements

    Azure-Specific Recommendations

    1. Use Managed Identity: Avoid connection strings in production

    2. Implement Circuit Breakers: Protect against Azure service outages

    3. Monitor Costs: Track message volume and processing costs

    4. Plan for Scale: Design partitioning and scaling strategies early

    5. Test Thoroughly: Use Azure DevTest Labs for comprehensive testing

    2. Request Cancellation

    Allow clients to cancel requests that are no longer needed or taking too long.

    Python Implementation

    
    from mcp.server import Server
    
    from mcp.types import CancelledError
    
    import asyncio

    @app.tool()
    
    async def download_file(url: str, ctx) -> str:

                downloaded = 0
    
                chunks = []
    
                
    
                async for chunk in response.content.iter_chunked(8192):

    Implementing Cancellation Context

    
    class CancellableContext:
    
        """Context object that tracks cancellation state."""
    
        
    
        def __init__(self, request_id: str):
    
            self.request_id = request_id
    
            self._cancelled = asyncio.Event()

            except asyncio.TimeoutError:
    
                pass  # Normal timeout, continue
    
    

    Client-Side Cancellation

    3. Resource Templates

    Resource templates allow dynamic URI construction with parameters, useful for APIs and databases.

    Defining Templates

    
    from mcp.server import Server
    
    from mcp.types import ResourceTemplate
    
    
    
    app = Server("template-server")

                mimeType="text/plain"
    
            )
    
        ]
    
    
    
    @app.read_resource()
    
    async def read_resource(uri: str) -> str:

            parts = uri.replace("api://weather/", "").split("/")
    
            city, date = parts[0], parts[1]

    TypeScript Implementation

    
    server.setRequestHandler(ListResourceTemplatesSchema, async () => {
    
      return {

    4. Server Lifecycle Events

    Proper initialization and shutdown handling ensures clean resource management.

    Python Lifecycle Management

    
    from mcp.server import Server
    
    from contextlib import asynccontextmanager
    
    
    
    app = Server("lifecycle-server")

        result = await db_connection.execute(sql)
    
        return str(result)
    
    

    TypeScript Lifecycle

    
    import { Server } from "@modelcontextprotocol/sdk/server/index.js";
    
    
    
    class ManagedServer {
    
      private server: Server;

        });
    
        
    
        this.setupHandlers();
    
      }
    
      
    
      async start() {
    
        // Initialize resources
    
        console.log("🚀 Server starting...");
    
        this.dbConnection = await createDatabaseConnection();

          // Use this.dbConnection safely
    
          // ...
    
        });
    
      }
    
    }
    
    
    
    // Usage with graceful shutdown
    
    const server = new ManagedServer();
    
    
    
    process.on('SIGINT', async () => {

    });
    
    
    
    await server.start();

    5. Logging Control

    MCP supports server-side logging levels that clients can control.

    Implementing Logging Levels

    
    from mcp.server import Server
    
    from mcp.types import LoggingLevel
    
    import logging
    
    
    
    app = Server("logging-server")
    
    
    
    # Map MCP levels to Python logging levels
    
    LEVEL_MAP = {
    
        LoggingLevel.DEBUG: logging.DEBUG,
    
        LoggingLevel.INFO: logging.INFO,
    
        LoggingLevel.WARNING: logging.WARNING,
    
        LoggingLevel.ERROR: logging.ERROR,
    
    }

    6. Error Handling Patterns

    Consistent error handling improves debugging and user experience.

    MCP Error Codes

    
    from mcp.types import McpError, ErrorCode
    
    
    
    class ToolError(McpError):
    
        """Base class for tool errors."""
    
        pass
    
    
    
    class ValidationError(ToolError):
    
        """Invalid input parameters."""
    
        def __init__(self, message: str):
    
            super().__init__(ErrorCode.INVALID_PARAMS, message)
    
    
    
    class NotFoundError(ToolError):
    
        """Requested resource not found."""
    
        def __init__(self, resource: str):
    
            super().__init__(ErrorCode.INVALID_REQUEST, f"Not found: {resource}")
    
    
    
    class PermissionError(ToolError):
    
        """Access denied."""
    
        def __init__(self, action: str):
    
            super().__init__(ErrorCode.INVALID_REQUEST, f"Permission denied: {action}")
    
    
    
    class InternalError(ToolError):
    
        """Internal server error."""
    
        def __init__(self, message: str):
    
            super().__init__(ErrorCode.INTERNAL_ERROR, message)
    
    

    Structured Error Responses

    
    @app.tool()
    
    async def safe_operation(input: str) -> str:
    
        """Tool with comprehensive error handling."""
    
        
    
        # Validate input
    
        if not input:
    
            raise ValidationError("Input cannot be empty")
    
        
    
        if len(input) > 10000:
    
            raise ValidationError(f"Input too large: {len(input)} chars (max 10000)")
    
        
    
        try:
    
            # Check permissions
    
            if not await check_permission(input):
    
                raise PermissionError(f"read {input}")
    
            
    
            # Perform operation
    
            result = await perform_operation(input)
    
            
    
            if result is None:
    
                raise NotFoundError(input)
    
            
    
            return result
    
            
    
        except ConnectionError as e:
    
            raise InternalError(f"Database connection failed: {e}")
    
        except TimeoutError as e:
    
            raise InternalError(f"Operation timed out: {e}")
    
        except Exception as e:
    
            # Log unexpected errors
    
            logger.exception(f"Unexpected error in safe_operation")
    
            raise InternalError(f"Unexpected error: {type(e).__name__}")
    
    

    Error Handling in TypeScript

    
    import { McpError, ErrorCode } from "@modelcontextprotocol/sdk/types.js";
    
    
    
    function validateInput(data: unknown): asserts data is ValidInput {
    
      if (typeof data !== "object" || data === null) {
    
        throw new McpError(
    
          ErrorCode.InvalidParams,
    
          "Input must be an object"
    
        );
    
      }
    
      // More validation...
    
    }
    
    
    
    server.setRequestHandler(CallToolSchema, async (request) => {
    
      try {
    
        validateInput(request.params.arguments);
    
        
    
        const result = await performOperation(request.params.arguments);
    
        
    
        return {
    
          content: [{ type: "text", text: JSON.stringify(result) }]
    
        };
    
        
    
      } catch (error) {
    
        if (error instanceof McpError) {
    
          throw error;  // Already an MCP error
    
        }
    
        
    
        // Convert other errors
    
        if (error instanceof NotFoundError) {
    
          throw new McpError(ErrorCode.InvalidRequest, error.message);
    
        }
    
        
    
        // Unknown error
    
        console.error("Unexpected error:", error);
    
        throw new McpError(
    
          ErrorCode.InternalError,
    
          "An unexpected error occurred"
    
        );
    
      }
    
    });

    Adversarial Multi-Agent Reasoning with MCP

    Multi-agent debate patterns use two or more agents with opposing positions to produce more reliable and well-calibrated outputs than a single agent can achieve alone.

    Introduction

    In this lesson, we explore the adversarial multi-agent pattern — a technique where two AI agents are assigned opposing positions on a topic and must reason, call MCP tools, and challenge each other's conclusions.

    A third agent (or a human reviewer) then evaluates the arguments and determines the best outcome.

    This pattern is especially useful for:

  • Hallucination detection: A second agent challenges unsubstantiated claims the first agent makes.
  • Threat modeling and security reviews: One agent argues that a system is safe; the other looks for vulnerabilities.
  • API or requirements design: One agent defends a proposed design; the other raises objections.
  • Factual verification: Both agents independently query the same MCP tools and cross-check each other's conclusions.
  • By sharing the same MCP tool set, both agents operate in the same information environment — which means any disagreement reflects genuine reasoning differences rather than an information asymmetry.

    Learning Objectives

    By the end of this lesson, you will be able to:

  • Explain why adversarial multi-agent patterns catch errors that single-agent pipelines miss.
  • Design a debate architecture where two agents share a common MCP tool set.
  • Implement "for" and "against" system prompts that guide each agent to argue its assigned position.
  • Add a judge agent (or human review step) that synthesizes the debate into a final verdict.
  • Understand how MCP tool-sharing works across concurrent agents.
  • Architecture Overview

    The adversarial pattern follows this high-level flow:

    Key design decisions

    Decision Rationale ---------- ----------- Both agents share one MCP server Eliminates information asymmetry — disagreements reflect reasoning, not data access Agents have opposing system prompts Forces each agent to stress-test the other side's position A judge agent synthesizes the debate Produces a single actionable output without human bottleneck Multiple debate rounds Allows each agent to respond to the other's tool-backed evidence

    Implementation

    Step 1 — Shared MCP Tool Server

    Start by exposing the tools that both agents will call. In this example we use a minimal Python MCP server built with FastMCP.

    Python – Shared Tool Server

    
    # shared_tools_server.py
    
    from mcp.server.fastmcp import FastMCP
    
    import httpx
    
    
    
    mcp = FastMCP("debate-tools")
    
    
    
    @mcp.tool()
    
    async def web_search(query: str) -> str:
    
        """Search the web and return a short summary of the top results."""
    
        # Replace with your preferred search API (e.g., SerpAPI, Brave Search).
    
        async with httpx.AsyncClient() as client:
    
            response = await client.get(
    
                "https://api.search.example.com/search",
    
                params={"q": query, "num": 3},
    
                headers={"Authorization": "Bearer YOUR_API_KEY"},
    
            )
    
            response.raise_for_status()
    
            results = response.json().get("results", [])
    
        snippets = "\n".join(r["snippet"] for r in results)
    
        return f"Search results for '{query}':\n{snippets}"
    
    
    
    @mcp.tool()
    
    async def run_python(code: str) -> str:
    
        """Execute a Python snippet and return stdout + stderr.

        """
    
        import subprocess, sys, textwrap
    
        result = subprocess.run(
    
            [sys.executable, "-c", textwrap.dedent(code)],
    
            capture_output=True, text=True, timeout=10
    
        )
    
        return result.stdout + result.stderr
    
    
    
    if __name__ == "__main__":
    
        mcp.run(transport="stdio")
    
    

    Run with:

    
    python shared_tools_server.py

    Step 2 — Agent System Prompts

    Each agent receives a system prompt that locks it into its assigned position. The key is that both agents know they are in a debate and that they *must* use tools to back their claims.

    Python – System Prompts

    
    # prompts.py
    
    
    
    FOR_SYSTEM_PROMPT = """You are Agent A in a structured debate.
    
    Your role is to argue *in favour* of the proposition given to you.
    
    Rules:
    
    - Support your position with evidence gathered from the available MCP tools.
    
    - Call the web_search tool to find real supporting data.
    
    - Call the run_python tool to verify quantitative claims with code.
    
    - When your opponent makes a claim, challenge it specifically and with evidence.
    
    - Do not concede your position unless your opponent provides irrefutable evidence.
    
    - Keep each turn concise (≤ 200 words)."""
    
    
    
    AGAINST_SYSTEM_PROMPT = """You are Agent B in a structured debate.
    
    Your role is to argue *against* the proposition given to you.
    
    Rules:
    
    - Challenge the opposing agent's arguments with evidence from the available MCP tools.
    
    - Call the web_search tool to find counter-evidence.
    
    - Call the run_python tool to verify or disprove quantitative claims with code.
    
    - Point out logical fallacies, missing context, or unsupported assertions.
    
    - Do not concede your position unless the evidence is irrefutable.
    
    - Keep each turn concise (≤ 200 words)."""
    
    
    
    JUDGE_SYSTEM_PROMPT = """You are an impartial judge evaluating a structured debate.
    
    Your task:
    
    1. Read the full debate transcript.
    
    2. Identify the strongest evidence-backed arguments on each side.
    
    3. Note any claims that were left unchallenged.
    
    4. Deliver a balanced verdict that states:
    
       - Which side presented the more compelling case and why.
    
       - Key caveats or nuances that neither side addressed adequately.
    
       - A confidence score (0–100) for the winning position."""
    
    

    ---

    Step 3 — Debate Orchestrator

    The orchestrator creates both agents, manages the debate turns, then passes the full transcript to the judge.

    Step 4 — Wiring MCP Tools into the Agents

    The Python orchestrator above already shows the complete MCP-wired implementation. The key pattern is:

  • One shared session: run_debate opens a single ClientSession and passes it to every run_agent_turn call, so both agents and the judge operate in the same tool environment.
  • Tool listing per turn: run_agent_turn calls session.list_tools() to fetch the current tool definitions and forwards them to the LLM as the tools parameter.
  • Tool-use loop: When the model returns tool_use blocks, run_agent_turn calls session.call_tool() for each one and feeds the results back to the model, repeating until the model produces a final text response.
  • Refer to 03-GettingStarted/02-client for complete MCP client examples in each language.

    Practical Use Cases

    Use Case FOR Agent AGAINST Agent Judge Output ---------- ----------- --------------- -------------- Threat modeling "This API endpoint is secure" "Here are five attack vectors" Prioritised risk list API design review "This design is optimal" "These trade-offs are problematic" Recommended design with caveats Factual verification "Claim X is supported by evidence" "Evidence Y contradicts claim X" Confidence-rated verdict Technology selection "Choose framework A" "Framework B is better for these reasons" Decision matrix with recommendation

    ---

    Security Considerations

    When running adversarial agents in production, keep these points in mind:

  • Sandbox code execution: The run_python tool must execute in an isolated environment (e.g., a container with no network access and resource limits). Never run untrusted LLM-generated code directly on the host.
  • Tool call validation: Validate all tool inputs before execution. Both agents share the same tool server, so a malicious prompt injected into the debate could attempt to misuse tools.
  • Rate limiting: Implement per-agent rate limits on tool calls to prevent runaway loops.
  • Audit logging: Log every tool call and result so you can review what evidence each agent used to reach its conclusions.
  • Human-in-the-loop: For high-stakes decisions, route the judge's verdict through a human reviewer before acting on it.
  • See 02-Security for a comprehensive guide to MCP security best practices.

    ---

    Exercise

    Design an adversarial MCP pipeline for one of the following scenarios:

    1. Code review: Agent A defends a pull request; Agent B looks for bugs, security issues, and style problems. The judge summarises the top issues.

    2. Architecture decision: Agent A proposes microservices; Agent B advocates for a monolith. The judge produces a decision matrix.

    3. Content moderation: Agent A argues a piece of content is safe to publish; Agent B finds policy violations. The judge assigns a risk score.

    For each scenario:

  • Define the system prompts for both agents and the judge.
  • Identify which MCP tools each agent needs.
  • Sketch the message flow (opening argument → rebuttal → counter-rebuttal → verdict).
  • Describe how you would validate the judge's verdict before acting on it.
  • ---

    Key Takeaways

  • Adversarial multi-agent patterns use opposing system prompts to force agents to stress-test each other's reasoning.
  • Sharing a single MCP tool server ensures both agents work from the same information, so disagreements are about reasoning, not data access.
  • A judge agent synthesizes the debate into an actionable verdict without requiring a human bottleneck for every decision.
  • This pattern is especially powerful for hallucination detection, threat modeling, factual verification, and design reviews.
  • Secure tool execution and robust logging are essential when running adversarial agents in production.

    Enterprise Integration

    When building MCP Servers in an enterprise context, you often need to integrate with existing AI platforms and services.

    This section covers how to integrate MCP with enterprise systems like Azure OpenAI and Microsoft AI Foundry, enabling advanced AI capabilities and tool orchestration.

    Introduction

    In this lesson, you'll learn how to integrate Model Context Protocol (MCP) with enterprise AI systems, focusing on Azure OpenAI and Microsoft AI Foundry.

    These integrations allow you to leverage powerful AI models and tools while maintaining the flexibility and extensibility of MCP.

    Learning Objectives

    By the end of this lesson, you will be able to:

  • Integrate MCP with Azure OpenAI to utilize its AI capabilities.
  • Implement MCP tool orchestration with Azure OpenAI.
  • Combine MCP with Microsoft AI Foundry for advanced AI agent capabilities.
  • Leverage Azure Machine Learning (ML) for executing ML pipelines and registering models as MCP tools.
  • Azure OpenAI Integration

    Azure OpenAI provides access to powerful AI models like GPT-4 and others. Integrating MCP with Azure OpenAI allows you to utilize these models while maintaining the flexibility of MCP's tool orchestration.

    C# Implementation

    In this code snippet, we demonstrate how to integrate MCP with Azure OpenAI using the Azure OpenAI SDK.

    
    // .NET Azure OpenAI Integration
    
    using Microsoft.Mcp.Client;
    
    using Azure.AI.OpenAI;
    
    using Microsoft.Extensions.Configuration;
    
    using System.Threading.Tasks;
    
    
    
    namespace EnterpriseIntegration
    
    {
    
        public class AzureOpenAiMcpClient
    
        {
    
            private readonly string _endpoint;
    
            private readonly string _apiKey;
    
            private readonly string _deploymentName;
    
            
    
            public AzureOpenAiMcpClient(IConfiguration config)
    
            {
    
                _endpoint = config["AzureOpenAI:Endpoint"];
    
                _apiKey = config["AzureOpenAI:ApiKey"];
    
                _deploymentName = config["AzureOpenAI:DeploymentName"];
    
            }
    
            
    
            public async Task<string> GetCompletionWithToolsAsync(string prompt, params string[] allowedTools)
    
            {
    
                // Create OpenAI client
    
                var client = new OpenAIClient(new Uri(_endpoint), new AzureKeyCredential(_apiKey));
    
                
    
                // Create completion options with tools
    
                var completionOptions = new ChatCompletionsOptions
    
                {
    
                    DeploymentName = _deploymentName,
    
                    Messages = { new ChatMessage(ChatRole.User, prompt) },
    
                    Temperature = 0.7f,
    
                    MaxTokens = 800
    
                };
    
                
    
                // Add tool definitions
    
                foreach (var tool in allowedTools)
    
                {
    
                    completionOptions.Tools.Add(new ChatCompletionsFunctionToolDefinition
    
                    {
    
                        Name = tool,
    
                        // In a real implementation, you'd add the tool schema here
    
                    });
    
                }
    
                
    
                // Get completion response
    
                var response = await client.GetChatCompletionsAsync(completionOptions);
    
                
    
                // Handle tool calls in the response
    
                foreach (var toolCall in response.Value.Choices[0].Message.ToolCalls)
    
                {
    
                    // Implementation to handle Azure OpenAI tool calls with MCP
    
                    // ...
    
                }
    
                
    
                return response.Value.Choices[0].Message.Content;
    
            }
    
        }
    
    }
    
    

    In the preceding code we've:

  • Configured the Azure OpenAI client with the endpoint, deployment name and API key.
  • Created a method GetCompletionWithToolsAsync to get completions with tool support.
  • Handled tool calls in the response.
  • You're encouraged to implement the actual tool handling logic based on your specific MCP server setup.

    Microsoft AI Foundry Integration

    Azure AI Foundry provides a platform for building and deploying AI agents. Integrating MCP with AI Foundry allows you to leverage its capabilities while maintaining the flexibility of MCP.

    In the below code, we develop an Agent integration that processes requests and handles tool calls using MCP.

    Java Implementation

    
    // Java AI Foundry Agent Integration
    
    package com.example.mcp.enterprise;
    
    
    
    import com.microsoft.aifoundry.AgentClient;

    import com.mcp.tools.ToolRequest;
    
    import com.mcp.tools.ToolResponse;
    
    
    
    public class AIFoundryMcpBridge {
    
        private final AgentClient agentClient;
    
        private final McpClient mcpClient;
    
        
    
        public AIFoundryMcpBridge(String aiFoundryEndpoint, String mcpServerUrl) {
    
            this.agentClient = new AgentClient(aiFoundryEndpoint);
    
            this.mcpClient = new McpClient.Builder()
    
                .setServerUrl(mcpServerUrl)
    
                .build();
    
        }
    
        
    
        public AgentResponse processAgentRequest(AgentRequest request) {
    
            // Process the AI Foundry Agent request
    
            AgentResponse initialResponse = agentClient.processRequest(request);
    
            
    
            // Check if the agent requested to use tools
    
            if (initialResponse.getToolCalls() != null && !initialResponse.getToolCalls().isEmpty()) {
    
                // For each tool call, route it to the appropriate MCP tool
    
                for (AgentToolCall toolCall : initialResponse.getToolCalls()) {
    
                    String toolName = toolCall.getName();
    
                    Map<String, Object> parameters = toolCall.getArguments();
    
                    
    
                    // Execute the tool using MCP
    
                    ToolResponse mcpResponse = mcpClient.executeTool(toolName, parameters);
    
                    
    
                    // Create tool response for AI Foundry
    
                    AgentToolResponse toolResponse = new AgentToolResponse(
    
                        toolCall.getId(),
    
                        mcpResponse.getResult()
    
                    );
    
                    
    
                    // Submit tool response back to the agent
    
                    initialResponse = agentClient.submitToolResponse(
    
                        request.getConversationId(), 
    
                        toolResponse
    
                    );
    
                }
    
            }
    
            
    
            return initialResponse;
    
        }
    
    }
    
    

    In the preceding code, we've:

  • Created an AIFoundryMcpBridge class that integrates with both AI Foundry and MCP.
  • Implemented a method processAgentRequest that processes an AI Foundry agent request.
  • Handled tool calls by executing them through the MCP client and submitting the results back to the AI Foundry agent.
  • Integrating MCP with Azure ML

    Integrating MCP with Azure Machine Learning (ML) allows you to leverage Azure's powerful ML capabilities while maintaining the flexibility of MCP.

    This integration can be used to execute ML pipelines, register models as tools, and manage compute resources.

    In the preceding code, we've:

  • Created an EnterpriseAiIntegration class that integrates MCP with Azure ML.
  • Implemented an execute_ml_pipeline method that processes input data using MCP tools and submits an ML pipeline to Azure ML.

    실용적인 구현

    _(위 이미지를 클릭하여 본 강의 영상을 보세요)_

    실용적인 구현은 모델 컨텍스트 프로토콜(MCP)의 힘을 구체화하는 부분입니다. MCP의 이론과 아키텍처를 이해하는 것도 중요하지만, 실제로 이러한 개념을 적용해 실제 문제를 해결하는 솔루션을 구축, 테스트, 배포할 때가 진짜 가치가 드러납니다. 이 장은 개념적 지식과 실전 개발 간의 격차를 메우며 MCP 기반 애플리케이션을 구현하는 과정을 안내합니다.

    지능형 어시스턴트를 개발하든, 비즈니스 워크플로우에 AI를 통합하든, 데이터 처리용 맞춤형 도구를 구축하든 MCP는 유연한 기반을 제공합니다. 언어에 구애받지 않는 설계와 인기 있는 프로그래밍 언어용 공식 SDK 덕분에 다양한 개발자들이 접근할 수 있습니다. 이들 SDK를 활용하면 다양한 플랫폼과 환경에서 솔루션을 빠르게 프로토타입하고 반복 발전시키며 확장할 수 있습니다.

    다음 섹션에서는 C#, Java(Spring 포함), TypeScript, JavaScript, Python에서 MCP를 구현하는 실용적인 예제, 샘플 코드, 배포 전략을 살펴봅니다.

    MCP 서버를 디버깅하고 테스트하는 법, API를 관리하는 법, 그리고 Azure를 이용해 솔루션을 클라우드에 배포하는 법도 배울 수 있습니다.

    이러한 실습 자료는 학습을 가속화하고 견고하고 프로덕션에 적합한 MCP 애플리케이션을 자신 있게 구축할 수 있도록 설계되었습니다.

    개요

    본 강의는 다양한 프로그래밍 언어에서 MCP 구현에 관한 실용적인 측면에 중점을 둡니다. C#, Java(Spring), TypeScript, JavaScript, Python용 MCP SDK를 활용해 견고한 애플리케이션을 구축하고, MCP 서버를 디버깅 및 테스트하며, 재사용 가능한 리소스, 프롬프트, 도구를 만드는 방법을 다룹니다.

    학습 목표

    이 강의를 완료하면 다음을 수행할 수 있습니다:

  • 다양한 프로그래밍 언어의 공식 SDK를 사용해 MCP 솔루션 구현
  • MCP 서버를 체계적으로 디버깅하고 테스트
  • 서버 기능(리소스, 프롬프트, 도구) 생성 및 활용
  • 복잡한 작업을 위한 효과적인 MCP 워크플로우 설계
  • 성능과 신뢰성을 최적화한 MCP 구현
  • 공식 SDK 리소스

    모델 컨텍스트 프로토콜은 여러 언어용 공식 SDK를 제공합니다 (MCP Specification 2025-11-25에 맞춤):

  • C# SDK
  • Java with Spring SDK 참고: Project Reactor 의존성 필요. (토론 이슈 246 참고)
  • TypeScript SDK
  • Python SDK
  • Kotlin SDK
  • Go SDK
  • MCP SDK 사용하기

    이 섹션에는 여러 프로그래밍 언어별 MCP 구현 실용 예제가 있습니다. samples 디렉터리에서 언어별 샘플 코드를 찾을 수 있습니다.

    제공되는 샘플

    다음 언어로 된 샘플 구현이 저장소에 포함되어 있습니다:

  • C#

    샘플

    이전 예제에서는 stdio 타입을 사용하는 로컬 .NET 프로젝트와 컨테이너에서 서버를 로컬로 실행하는 방법을 보여주었습니다.

    이는 많은 상황에서 좋은 해결책입니다.

    하지만 서버를 클라우드 환경처럼 원격에서 실행하는 것도 유용할 수 있습니다.

    이럴 때 http 타입이 필요합니다.

    04-PracticalImplementation 폴더의 솔루션을 보면 이전 예제보다 훨씬 복잡해 보일 수 있습니다.

    하지만 실제로는 그렇지 않습니다. src/Calculator 프로젝트를 자세히 살펴보면 이전 예제와 거의 동일한 코드임을 알 수 있습니다.

    유일한 차이점은 HTTP 요청을 처리하기 위해 다른 라이브러리인 ModelContextProtocol.AspNetCore를 사용한다는 점과, IsPrime 메서드를 private으로 변경하여 코드 내에 private 메서드를 가질 수 있음을 보여준다는 점입니다.

    나머지 코드는 이전과 동일합니다.

    다른 프로젝트들은 .NET Aspire에서 가져온 것입니다.

    솔루션에 .NET Aspire를 포함하면 개발 및 테스트 과정에서 개발자 경험이 향상되고 관찰 가능성도 좋아집니다.

    서버 실행에 필수는 아니지만 솔루션에 포함하는 것이 좋은 습관입니다.

    서버를 로컬에서 시작하기

    1. VS Code(C# DevKit 확장 기능 포함)에서 04-PracticalImplementation/samples/csharp 디렉터리로 이동합니다.

    1. 다음 명령어를 실행하여 서버를 시작합니다:

    ```bash

    dotnet watch run --project ./src/AppHost

    ```

    1.

    웹 브라우저가 .NET Aspire 대시보드를 열면 http URL을 확인하세요.

    보통 http://localhost:5058/와 비슷할 것입니다.

    !.NET Aspire Dashboard

    MCP Inspector로 Streamable HTTP 테스트하기

    Node.js 22.7.5 이상이 설치되어 있다면 MCP Inspector를 사용해 서버를 테스트할 수 있습니다.

    서버를 시작한 후 터미널에서 다음 명령어를 실행하세요:

    
    npx @modelcontextprotocol/inspector http://localhost:5058
    
    
  • Transport 타입으로 Streamable HTTP를 선택합니다.
  • Url 필드에 앞서 확인한 서버 URL을 입력하고 /mcp를 덧붙입니다. http (https 아님) 형식이어야 하며, 예를 들어 http://localhost:5058/mcp와 같습니다.
  • Connect 버튼을 클릭합니다.
  • Inspector의 좋은 점은 현재 진행 중인 상황을 잘 보여준다는 것입니다.

  • 사용 가능한 도구 목록을 불러와 보세요.
  • 몇 가지 도구를 사용해 보세요. 이전과 동일하게 작동할 것입니다.
  • VS Code에서 GitHub Copilot Chat으로 MCP 서버 테스트하기

    GitHub Copilot Chat에서 Streamable HTTP 전송을 사용하려면, 이전에 만든 calc-mcp 서버 구성을 다음과 같이 변경하세요:

    
    // .vscode/mcp.json
    
    {
    
      "servers": {
    
        "calc-mcp": {
    
          "type": "http",
    
          "url": "http://localhost:5058/mcp"
    
        }
    
      }
    
    }
    
    

    몇 가지 테스트를 해보세요:

  • "6780 이후의 소수 3개"를 요청해 보세요. Copilot이 새 도구 NextFivePrimeNumbers를 사용해 처음 3개의 소수만 반환하는 것을 확인할 수 있습니다.
  • "111 이후의 소수 7개"를 요청해 보세요. 어떤 결과가 나오는지 확인해 보세요.
  • "John이 사탕 24개를 가지고 있고 3명의 아이들에게 모두 나누어 주려고 합니다. 각 아이가 몇 개씩 받나요?"를 물어보세요. 어떤 결과가 나오는지 확인해 보세요.
  • 서버를 Azure에 배포하기

    더 많은 사용자가 서버를 이용할 수 있도록 Azure에 배포해 봅시다.

    터미널에서 04-PracticalImplementation/samples/csharp 폴더로 이동한 후 다음 명령어를 실행하세요:

    
    azd up
    
    

    배포가 완료되면 다음과 같은 메시지를 볼 수 있습니다:

    URL을 복사하여 MCP Inspector와 GitHub Copilot Chat에서 사용하세요.

    
    // .vscode/mcp.json
    
    {
    
      "servers": {
    
        "calc-mcp": {
    
          "type": "http",
    
          "url": "https://calc-mcp.gentleriver-3977fbcf.australiaeast.azurecontainerapps.io/mcp"
    
        }
    
      }
    
    }
    
    

    다음은?

    우리는 다양한 전송 타입과 테스트 도구를 시도해 보았고, MCP 서버를 Azure에 배포했습니다. 그렇다면 서버가 사설 리소스에 접근해야 한다면 어떻게 할까요? 예를 들어 데이터베이스나 사설 API 같은 경우 말이죠. 다음 장에서는 서버의 보안을 어떻게 강화할 수 있는지 살펴보겠습니다.

  • Java with Spring

    시스템 아키텍처

    이 프로젝트는 사용자 프롬프트를 계산기 서비스에 전달하기 전에 콘텐츠 안전성 검사를 수행하는 웹 애플리케이션을 Model Context Protocol (MCP)을 통해 구현한 예시입니다.

    작동 방식

    1. 사용자 입력: 사용자가 웹 인터페이스에 계산 프롬프트를 입력합니다.

    2. 콘텐츠 안전성 검사 (입력): 프롬프트는 Azure Content Safety API로 분석됩니다.

    3. 안전성 판단 (입력):

    - 모든 카테고리에서 심각도(severity)가 2 미만인 경우 안전하다고 판단되어 계산기로 전달됩니다.

    - 잠재적으로 유해한 콘텐츠로 표시되면 프로세스가 중단되고 경고가 반환됩니다.

    4. 계산기 연동: 안전한 콘텐츠는 LangChain4j를 통해 MCP 계산기 서버와 통신하여 처리됩니다.

    5. 콘텐츠 안전성 검사 (출력): 봇의 응답은 Azure Content Safety API로 분석됩니다.

    6. 안전성 판단 (출력):

    - 봇 응답이 안전하면 사용자에게 표시됩니다.

    - 잠재적으로 유해한 응답으로 표시되면 경고 메시지로 대체됩니다.

    7. 응답: 결과(안전한 경우)는 사용자에게 두 번의 안전성 분석 결과와 함께 표시됩니다.

    Model Context Protocol (MCP)을 이용한 계산기 서비스 사용법

    이 프로젝트는 LangChain4j에서 Model Context Protocol (MCP)을 사용해 계산기 MCP 서비스를 호출하는 방법을 보여줍니다. 구현은 포트 8080에서 실행되는 로컬 MCP 서버를 통해 계산기 연산을 제공합니다.

    Azure Content Safety 서비스 설정

    콘텐츠 안전성 기능을 사용하기 전에 Azure Content Safety 서비스 리소스를 생성해야 합니다:

    1. Azure Portal에 로그인합니다.

    2. "리소스 만들기"를 클릭하고 "Content Safety"를 검색합니다.

    3. "Content Safety"를 선택하고 "만들기"를 클릭합니다.

    4. 리소스에 고유한 이름을 입력합니다.

    5. 구독과 리소스 그룹을 선택하거나 새로 만듭니다.

    6. 지원되는 지역을 선택합니다 (지역 가용성 참고).

    7. 적절한 가격 책정 계층을 선택합니다.

    8. "만들기"를 클릭하여 리소스를 배포합니다.

    9. 배포가 완료되면 "리소스로 이동"을 클릭합니다.

    10. 왼쪽 메뉴에서 "리소스 관리" 아래의 "키 및 엔드포인트"를 선택합니다.

    11. 다음 단계에서 사용할 키 중 하나와 엔드포인트 URL을 복사합니다.

    환경 변수 설정

    GitHub 모델 인증을 위해 GITHUB_TOKEN 환경 변수를 설정하세요:

    
    export GITHUB_TOKEN=<your_github_token>
    
    

    콘텐츠 안전성 기능을 위해 다음을 설정하세요:

    
    export CONTENT_SAFETY_ENDPOINT=<your_content_safety_endpoint>
    
    export CONTENT_SAFETY_KEY=<your_content_safety_key>
    
    

    이 환경 변수들은 애플리케이션이 Azure Content Safety 서비스에 인증하는 데 사용됩니다. 설정하지 않으면 데모용 자리 표시자 값이 사용되지만 콘텐츠 안전성 기능은 제대로 작동하지 않습니다.

    계산기 MCP 서버 시작

    클라이언트를 실행하기 전에 localhost:8080에서 SSE 모드로 계산기 MCP 서버를 시작해야 합니다.

    프로젝트 설명

    이 프로젝트는 LangChain4j와 Model Context Protocol (MCP)을 통합하여 계산기 서비스를 호출하는 방법을 보여줍니다. 주요 기능은 다음과 같습니다:

  • MCP를 사용해 기본 수학 연산을 위한 계산기 서비스에 연결
  • 사용자 프롬프트와 봇 응답 모두에 대한 이중 콘텐츠 안전성 검사
  • LangChain4j를 통한 GitHub의 gpt-4.1-nano 모델 연동
  • MCP 전송에 Server-Sent Events (SSE) 사용
  • 콘텐츠 안전성 통합

    이 프로젝트는 사용자 입력과 시스템 응답 모두에서 유해한 콘텐츠가 없도록 포괄적인 콘텐츠 안전성 기능을 포함합니다:

    1. 입력 검사: 모든 사용자 프롬프트는 증오 발언, 폭력, 자해, 성적 콘텐츠 등 유해 콘텐츠 카테고리에 대해 처리 전에 분석됩니다.

    2. 출력 검사: 잠재적으로 검열되지 않은 모델을 사용하더라도, 생성된 모든 응답은 사용자에게 표시되기 전에 동일한 콘텐츠 안전성 필터를 거칩니다.

    이중 검사 방식을 통해 어떤 AI 모델을 사용하더라도 시스템이 안전하게 유지되며, 사용자와 AI 생성 출력 모두를 유해한 콘텐츠로부터 보호합니다.

    웹 클라이언트

    애플리케이션은 사용자가 Content Safety Calculator 시스템과 상호작용할 수 있는 직관적인 웹 인터페이스를 제공합니다:

    웹 인터페이스 기능

  • 계산 프롬프트 입력을 위한 간단하고 직관적인 폼
  • 입력과 출력 모두에 대한 이중 콘텐츠 안전성 검증
  • 프롬프트와 응답 안전성에 대한 실시간 피드백
  • 쉽게 이해할 수 있는 색상 구분 안전성 표시기
  • 다양한 기기에서 작동하는 깔끔하고 반응형 디자인
  • 사용자를 위한 안전한 예시 프롬프트 제공
  • 웹 클라이언트 사용법

    1. 애플리케이션을 시작합니다:

    ```sh

    mvn spring-boot:run

    ```

    2. 브라우저를 열고 http://localhost:8087로 접속합니다.

    3. 제공된 텍스트 영역에 계산 프롬프트를 입력합니다 (예: "24.5와 17.3의 합을 계산해 주세요").

    4. "Submit" 버튼을 클릭하여 요청을 처리합니다.

    5. 결과를 확인합니다. 결과에는 다음이 포함됩니다:

    - 프롬프트에 대한 콘텐츠 안전성 분석

    - 계산된 결과 (프롬프트가 안전한 경우)

    - 봇 응답에 대한 콘텐츠 안전성 분석

    - 입력 또는 출력이 플래그된 경우 안전성 경고

    웹 클라이언트는 두 단계의 콘텐츠 안전성 검증을 자동으로 처리하여, 어떤 AI 모델을 사용하더라도 모든 상호작용이 안전하고 적절하게 이루어지도록 보장합니다.

    Model Context Protocol (MCP) Python 구현

    이 저장소에는 Model Context Protocol (MCP)의 Python 구현이 포함되어 있으며, MCP 표준을 사용하여 통신하는 서버와 클라이언트 애플리케이션을 만드는 방법을 보여줍니다.

    개요

    MCP 구현은 두 가지 주요 구성 요소로 이루어져 있습니다:

    1. MCP 서버 (server.py) - 다음을 제공하는 서버:

    - Tools: 원격으로 호출할 수 있는 함수들

    - Resources: 가져올 수 있는 데이터

    - Prompts: 언어 모델용 프롬프트 템플릿

    2. MCP 클라이언트 (client.py) - 서버에 연결하여 기능을 사용하는 클라이언트 애플리케이션

    기능

    이 구현은 여러 주요 MCP 기능을 보여줍니다:

    Tools

  • completion - AI 모델로부터 텍스트 완성을 생성 (시뮬레이션)
  • add - 두 숫자를 더하는 간단한 계산기
  • Resources

  • 설치

    이 MCP 구현을 사용하려면 필요한 패키지를 설치하세요:

    
    pip install mcp-server mcp-client
    
    

    서버 및 클라이언트 실행

    서버 시작

    한 터미널 창에서 서버를 실행하세요:

    
    python server.py
    
    

    서버는 MCP CLI를 사용하여 개발 모드로도 실행할 수 있습니다:

    
    mcp dev server.py
    
    

    또는 Claude Desktop에 설치하여 실행할 수도 있습니다 (사용 가능한 경우):

    
    mcp install server.py
    
    

    클라이언트 실행

    다른 터미널 창에서 클라이언트를 실행하세요:

    
    python client.py
    
    

    이렇게 하면 서버에 연결되어 모든 기능을 시연합니다.

    클라이언트 사용법

    클라이언트(client.py)는 MCP의 모든 기능을 보여줍니다:

    
    python client.py
    
    

    서버에 연결하여 tools, resources, prompts를 포함한 모든 기능을 사용합니다. 출력 결과는 다음을 보여줍니다:

    1. 계산기 도구 결과 (5 + 7 = 12)

    2. "What is the meaning of life?"에 대한 completion 도구 응답

    3. 사용 가능한 AI 모델 목록

    4. "MCP Explorer"에 대한 맞춤 인사

    5. 코드 리뷰 프롬프트 템플릿

    구현 세부사항

    서버는 MCP 서비스를 정의하기 위한 고수준 추상화를 제공하는 FastMCP API를 사용하여 구현되었습니다. 다음은 도구가 정의되는 간단한 예시입니다:

    
    @mcp.tool()
    
    def add(a: int, b: int) -> int:
    
        """Add two numbers together
    
        
    
        Args:
    
            a: First number
    
            b: Second number
    
        
    
        Returns:
    
            The sum of the two numbers
    
        """
    
        logger.info(f"Adding {a} and {b}")
    
        return a + b
    
    

    클라이언트는 MCP 클라이언트 라이브러리를 사용하여 서버에 연결하고 호출합니다:

    
    async with stdio_client(server_params) as (reader, writer):
    
        async with ClientSession(reader, writer) as session:
    
            await session.initialize()
    
            result = await session.call_tool("add", arguments={"a": 5, "b": 7})

    실용 가이드

    추가 MCP 실용 구현 가이드:

  • 페이지네이션과 큰 결과 집합

    MCP에서 페이지네이션과 대용량 결과 집합

    MCP 서버가 수천 개의 파일, 데이터베이스 레코드 또는 검색 결과와 같은 대규모 데이터셋을 처리할 때 메모리를 효율적으로 관리하고 반응성 있는 사용자 경험을 제공하려면 페이지네이션이 필요합니다. 이 가이드는 MCP에서 페이지네이션을 구현하고 사용하는 방법을 다룹니다.

    페이지네이션이 중요한 이유

    페이지네이션이 없으면 대규모 응답이 다음과 같은 문제를 일으킬 수 있습니다:

  • 메모리 부족 - 수백만 개의 레코드를 한 번에 로드
  • 느린 응답 시간 - 모든 데이터가 로드될 때까지 사용자 대기
  • 타임아웃 오류 - 요청이 타임아웃 제한을 초과
  • AI 성능 저하 - LLM이 방대한 컨텍스트를 처리하는 데 어려움
  • MCP는 결과 집합을 안정적이고 일관되게 페이지 처리하기 위해 커서 기반 페이지네이션을 사용합니다.

    MCP 페이지네이션 동작 방식

    커서 개념

    커서는 결과 집합 내 위치를 표시하는 불투명한 문자열입니다. 긴 책에서의 북마크와 같이 생각할 수 있습니다.

    
    sequenceDiagram
    
        participant Client
    
        participant Server
    
        
    
        Client->>Server: tools/list (커서 없음)
    
        Server-->>Client: 도구 [1-10], 다음커서: "abc123"
    
        
    
        Client->>Server: tools/list (커서: "abc123")

    지연 로딩 패턴

    매우 큰 데이터셋의 경우 필요에 따라 페이지를 로드하세요:

    리소스용 페이지네이션

    리소스는 디렉터리나 대규모 데이터셋에 대해 페이지네이션이 자주 필요합니다:

    
    from mcp.server import Server
    
    from mcp.types import Resource, ListResourcesResult
    
    import os
    
    
    
    app = Server("file-server")
    
    
    
    @app.list_resources()
    
    async def list_resources(cursor: str | None = None) -> ListResourcesResult:
    
        """List files in directory with pagination."""
    
        
    
        directory = "/data/files"
    
        all_files = sorted(os.listdir(directory))
    
        
    
        # 커서 디코딩 (파일 인덱스)
    
        start_index = int(cursor) if cursor else 0
    
        page_size = 20
    
        end_index = min(start_index + page_size, len(all_files))
    
        
    
        # 이 페이지에 대한 리소스 리스트 생성
    
        resources = []
    
        for filename in all_files[start_index:end_index]:
    
            filepath = os.path.join(directory, filename)
    
            resources.append(Resource(
    
                uri=f"file://{filepath}",
    
                name=filename,
    
                mimeType="application/octet-stream"
    
            ))
    
        
    
        # 다음 커서 계산
    
        next_cursor = str(end_index) if end_index < len(all_files) else None
    
        
    
        return ListResourcesResult(
    
            resources=resources,
    
            nextCursor=next_cursor
    
        )

    커서 설계 전략

    전략 1: 인덱스 기반 (단순)

    
    # 커서는 단지 인덱스입니다
    
    cursor = "50"  # 50번째 항목에서 시작합니다
    
    

    장점: 단순하고 상태 비저장

    단점: 항목이 추가/삭제되면 결과가 이동할 수 있음

    전략 2: ID 기반 (안정적)

    
    # 커서는 마지막으로 본 ID입니다
    
    cursor = "item_abc123"  # 이 항목 다음부터 시작합니다
    
    

    장점: 항목이 변경되어도 안정적

    단점: 정렬된 ID 필요

    전략 3: 인코딩된 상태 (복잡)

    
    import base64
    
    import json
    
    
    
    def encode_cursor(state: dict) -> str:
    
        return base64.b64encode(json.dumps(state).encode()).decode()
    
    
    
    def decode_cursor(cursor: str) -> dict:
    
        return json.loads(base64.b64decode(cursor).decode())
    
    
    
    # 커서는 여러 상태 필드를 포함합니다
    
    cursor = encode_cursor({
    
        "offset": 50,
    
        "filter": "active",
    
        "sort": "name"
    
    })
    
    

    장점: 복잡한 상태를 인코딩 가능

    단점: 더 복잡하고 커서 문자열이 길어짐

    모범 사례

    1. 적절한 페이지 크기 선택

    
    # 데이터 크기를 고려하세요
    
    PAGE_SIZE_SMALL_ITEMS = 100   # 간단한 메타데이터
    
    PAGE_SIZE_MEDIUM_ITEMS = 20   # 더 풍부한 객체
    
    PAGE_SIZE_LARGE_ITEMS = 5     # 복잡한 내용
    
    

    2. 잘못된 커서 우아하게 처리

    
    @app.list_tools()
    
    async def list_tools(cursor: str | None = None) -> ListToolsResult:
    
        try:
    
            start_index = int(cursor) if cursor else 0
    
            if start_index < 0 or start_index >= len(ALL_TOOLS):
    
                start_index = 0  # 처음으로 재설정
    
        except (ValueError, TypeError):
    
            start_index = 0  # 잘못된 커서, 새로 시작
    
        # ...
    
    

    3. 총 개수 포함 (선택 사항)

    
    return ListToolsResult(
    
        tools=page_tools,
    
        nextCursor=next_cursor,
    
        # 일부 구현은 UI 진행 상황을 위한 전체 합계를 포함합니다
    
        _meta={"total": len(ALL_TOOLS)}
    
    )
    
    

    4. 극단적 케이스 테스트

    
    async def test_pagination():
    
        # 빈 결과 집합
    
        result = await session.list_tools()
    
        assert result.tools == []
    
        assert result.nextCursor is None
    
        
    
        # 단일 페이지
    
        result = await session.list_tools()
    
        assert len(result.tools) <= PAGE_SIZE

        result = await session.list_tools(cursor="invalid")
    
        assert result.tools  # 첫 페이지를 반환해야 함
    
    

    ---

    자주 하는 실수

    ❌ 모든 결과를 반환한 후 클라이언트에서 페이지네이션 수행

    
    # 나쁨: 모든 것을 메모리에 로드함
    
    @app.list_tools()
    
    async def list_tools() -> ListToolsResult:
    
        all_tools = load_all_tools()  # 100만 개의 도구!
    
        return ListToolsResult(tools=all_tools)
    
    

    ✅ 데이터 소스에서 페이지네이션 수행

    
    # 좋음: 필요한 것만 로드합니다
    
    @app.list_tools()
    
    async def list_tools(cursor: str | None = None) -> ListToolsResult:
    
        offset = int(cursor) if cursor else 0
    
        tools = await db.query_tools(offset=offset, limit=PAGE_SIZE)
    
        return ListToolsResult(tools=tools, nextCursor=...)

    시스템 아키텍처

    이 프로젝트는 사용자 프롬프트를 계산기 서비스에 전달하기 전에 콘텐츠 안전성 검사를 수행하는 웹 애플리케이션을 Model Context Protocol (MCP)을 통해 구현한 예시입니다.

    작동 방식

    1. 사용자 입력: 사용자가 웹 인터페이스에 계산 프롬프트를 입력합니다.

    2. 콘텐츠 안전성 검사 (입력): 프롬프트는 Azure Content Safety API로 분석됩니다.

    3. 안전성 판단 (입력):

    - 모든 카테고리에서 심각도(severity)가 2 미만인 경우 안전하다고 판단되어 계산기로 전달됩니다.

    - 잠재적으로 유해한 콘텐츠로 표시되면 프로세스가 중단되고 경고가 반환됩니다.

    4. 계산기 연동: 안전한 콘텐츠는 LangChain4j를 통해 MCP 계산기 서버와 통신하여 처리됩니다.

    5. 콘텐츠 안전성 검사 (출력): 봇의 응답은 Azure Content Safety API로 분석됩니다.

    6. 안전성 판단 (출력):

    - 봇 응답이 안전하면 사용자에게 표시됩니다.

    - 잠재적으로 유해한 응답으로 표시되면 경고 메시지로 대체됩니다.

    7. 응답: 결과(안전한 경우)는 사용자에게 두 번의 안전성 분석 결과와 함께 표시됩니다.

    Model Context Protocol (MCP)을 이용한 계산기 서비스 사용법

    이 프로젝트는 LangChain4j에서 Model Context Protocol (MCP)을 사용해 계산기 MCP 서비스를 호출하는 방법을 보여줍니다. 구현은 포트 8080에서 실행되는 로컬 MCP 서버를 통해 계산기 연산을 제공합니다.

    Azure Content Safety 서비스 설정

    콘텐츠 안전성 기능을 사용하기 전에 Azure Content Safety 서비스 리소스를 생성해야 합니다:

    1. Azure Portal에 로그인합니다.

    2. "리소스 만들기"를 클릭하고 "Content Safety"를 검색합니다.

    3. "Content Safety"를 선택하고 "만들기"를 클릭합니다.

    4. 리소스에 고유한 이름을 입력합니다.

    5. 구독과 리소스 그룹을 선택하거나 새로 만듭니다.

    6. 지원되는 지역을 선택합니다 (지역 가용성 참고).

    7. 적절한 가격 책정 계층을 선택합니다.

    8. "만들기"를 클릭하여 리소스를 배포합니다.

    9. 배포가 완료되면 "리소스로 이동"을 클릭합니다.

    10. 왼쪽 메뉴에서 "리소스 관리" 아래의 "키 및 엔드포인트"를 선택합니다.

    11. 다음 단계에서 사용할 키 중 하나와 엔드포인트 URL을 복사합니다.

    환경 변수 설정

    GitHub 모델 인증을 위해 GITHUB_TOKEN 환경 변수를 설정하세요:

    
    export GITHUB_TOKEN=<your_github_token>
    
    

    콘텐츠 안전성 기능을 위해 다음을 설정하세요:

    
    export CONTENT_SAFETY_ENDPOINT=<your_content_safety_endpoint>
    
    export CONTENT_SAFETY_KEY=<your_content_safety_key>
    
    

    이 환경 변수들은 애플리케이션이 Azure Content Safety 서비스에 인증하는 데 사용됩니다. 설정하지 않으면 데모용 자리 표시자 값이 사용되지만 콘텐츠 안전성 기능은 제대로 작동하지 않습니다.

    계산기 MCP 서버 시작

    클라이언트를 실행하기 전에 localhost:8080에서 SSE 모드로 계산기 MCP 서버를 시작해야 합니다.

    프로젝트 설명

    이 프로젝트는 LangChain4j와 Model Context Protocol (MCP)을 통합하여 계산기 서비스를 호출하는 방법을 보여줍니다. 주요 기능은 다음과 같습니다:

  • MCP를 사용해 기본 수학 연산을 위한 계산기 서비스에 연결
  • 사용자 프롬프트와 봇 응답 모두에 대한 이중 콘텐츠 안전성 검사
  • LangChain4j를 통한 GitHub의 gpt-4.1-nano 모델 연동
  • MCP 전송에 Server-Sent Events (SSE) 사용
  • 콘텐츠 안전성 통합

    이 프로젝트는 사용자 입력과 시스템 응답 모두에서 유해한 콘텐츠가 없도록 포괄적인 콘텐츠 안전성 기능을 포함합니다:

    1. 입력 검사: 모든 사용자 프롬프트는 증오 발언, 폭력, 자해, 성적 콘텐츠 등 유해 콘텐츠 카테고리에 대해 처리 전에 분석됩니다.

    2. 출력 검사: 잠재적으로 검열되지 않은 모델을 사용하더라도, 생성된 모든 응답은 사용자에게 표시되기 전에 동일한 콘텐츠 안전성 필터를 거칩니다.

    이중 검사 방식을 통해 어떤 AI 모델을 사용하더라도 시스템이 안전하게 유지되며, 사용자와 AI 생성 출력 모두를 유해한 콘텐츠로부터 보호합니다.

    웹 클라이언트

    애플리케이션은 사용자가 Content Safety Calculator 시스템과 상호작용할 수 있는 직관적인 웹 인터페이스를 제공합니다:

    웹 인터페이스 기능

  • 계산 프롬프트 입력을 위한 간단하고 직관적인 폼
  • 입력과 출력 모두에 대한 이중 콘텐츠 안전성 검증
  • 프롬프트와 응답 안전성에 대한 실시간 피드백
  • 쉽게 이해할 수 있는 색상 구분 안전성 표시기
  • 다양한 기기에서 작동하는 깔끔하고 반응형 디자인
  • 사용자를 위한 안전한 예시 프롬프트 제공
  • 웹 클라이언트 사용법

    1. 애플리케이션을 시작합니다:

    ```sh

    mvn spring-boot:run

    ```

    2. 브라우저를 열고 http://localhost:8087로 접속합니다.

    3. 제공된 텍스트 영역에 계산 프롬프트를 입력합니다 (예: "24.5와 17.3의 합을 계산해 주세요").

    4. "Submit" 버튼을 클릭하여 요청을 처리합니다.

    5. 결과를 확인합니다. 결과에는 다음이 포함됩니다:

    - 프롬프트에 대한 콘텐츠 안전성 분석

    - 계산된 결과 (프롬프트가 안전한 경우)

    - 봇 응답에 대한 콘텐츠 안전성 분석

    - 입력 또는 출력이 플래그된 경우 안전성 경고

    웹 클라이언트는 두 단계의 콘텐츠 안전성 검증을 자동으로 처리하여, 어떤 AI 모델을 사용하더라도 모든 상호작용이 안전하고 적절하게 이루어지도록 보장합니다.

    Model Context Protocol (MCP) Python 구현

    이 저장소에는 Model Context Protocol (MCP)의 Python 구현이 포함되어 있으며, MCP 표준을 사용하여 통신하는 서버와 클라이언트 애플리케이션을 만드는 방법을 보여줍니다.

    개요

    MCP 구현은 두 가지 주요 구성 요소로 이루어져 있습니다:

    1. MCP 서버 (server.py) - 다음을 제공하는 서버:

    - Tools: 원격으로 호출할 수 있는 함수들

    - Resources: 가져올 수 있는 데이터

    - Prompts: 언어 모델용 프롬프트 템플릿

    2. MCP 클라이언트 (client.py) - 서버에 연결하여 기능을 사용하는 클라이언트 애플리케이션

    기능

    이 구현은 여러 주요 MCP 기능을 보여줍니다:

    Tools

  • completion - AI 모델로부터 텍스트 완성을 생성 (시뮬레이션)
  • add - 두 숫자를 더하는 간단한 계산기
  • Resources

  • models:// - 사용 가능한 AI 모델에 대한 정보 반환
  • greeting://{name} - 주어진 이름에 대한 맞춤 인사 반환
  • Prompts

  • review_code - 코드 리뷰용 프롬프트 생성
  • 설치

    이 MCP 구현을 사용하려면 필요한 패키지를 설치하세요:

    
    pip install mcp-server mcp-client
    
    

    서버 및 클라이언트 실행

    서버 시작

    한 터미널 창에서 서버를 실행하세요:

    
    python server.py
    
    

    서버는 MCP CLI를 사용하여 개발 모드로도 실행할 수 있습니다:

    
    mcp dev server.py
    
    

    또는 Claude Desktop에 설치하여 실행할 수도 있습니다 (사용 가능한 경우):

    
    mcp install server.py
    
    

    클라이언트 실행

    다른 터미널 창에서 클라이언트를 실행하세요:

    
    python client.py
    
    

    이렇게 하면 서버에 연결되어 모든 기능을 시연합니다.

    클라이언트 사용법

    클라이언트(client.py)는 MCP의 모든 기능을 보여줍니다:

    
    python client.py
    
    

    서버에 연결하여 tools, resources, prompts를 포함한 모든 기능을 사용합니다. 출력 결과는 다음을 보여줍니다:

    1. 계산기 도구 결과 (5 + 7 = 12)

    2. "What is the meaning of life?"에 대한 completion 도구 응답

    3. 사용 가능한 AI 모델 목록

    4. "MCP Explorer"에 대한 맞춤 인사

    5. 코드 리뷰 프롬프트 템플릿

    구현 세부사항

    서버는 MCP 서비스를 정의하기 위한 고수준 추상화를 제공하는 FastMCP API를 사용하여 구현되었습니다. 다음은 도구가 정의되는 간단한 예시입니다:

    
    @mcp.tool()
    
    def add(a: int, b: int) -> int:
    
        """Add two numbers together
    
        
    
        Args:
    
            a: First number
    
            b: Second number
    
        
    
        Returns:
    
            The sum of the two numbers
    
        """
    
        logger.info(f"Adding {a} and {b}")
    
        return a + b
    
    

    클라이언트는 MCP 클라이언트 라이브러리를 사용하여 서버에 연결하고 호출합니다:

    
    async with stdio_client(server_params) as (reader, writer):
    
        async with ClientSession(reader, writer) as session:
    
            await session.initialize()
    
            result = await session.call_tool("add", arguments={"a": 5, "b": 7})

    다중 모달 통합

    다중 모달 애플리케이션은 AI에서 점점 더 중요해지고 있으며, 더 풍부한 상호작용과 복잡한 작업 수행을 가능하게 합니다. Model Context Protocol(MCP)은 텍스트, 이미지, 오디오 등 다양한 유형의 데이터를 처리할 수 있는 다중 모달 애플리케이션을 구축하기 위한 프레임워크를 제공합니다.

    MCP는 텍스트 기반 상호작용뿐만 아니라 이미지, 오디오 및 기타 데이터 유형을 다룰 수 있는 다중 모달 기능도 지원합니다.

    소개

    이번 수업에서는 다중 모달 애플리케이션을 만드는 방법을 배웁니다.

    학습 목표

    이 수업이 끝나면 다음을 할 수 있습니다:

  • 다중 모달 선택지를 이해하기
  • 다중 모달 앱 구현하기
  • 다중 모달 지원 아키텍처

    다중 모달 MCP 구현은 일반적으로 다음을 포함합니다:

  • 모달별 파서: 모델이 처리할 수 있는 형식으로 다양한 미디어 유형을 변환하는 구성 요소
  • 모달별 도구: 특정 모달리티(예: 이미지 분석, 오디오 처리)를 다루기 위한 특수 도구
  • 통합 컨텍스트 관리: 서로 다른 모달리티 간의 컨텍스트를 유지하는 시스템
  • 응답 생성: 여러 모달리티를 포함할 수 있는 응답을 생성하는 기능
  • 다중 모달 예제: 이미지 분석

    아래 예제에서는 이미지를 분석하고 정보를 추출합니다.

    위 예제에서는 다음을 수행했습니다:

  • 가상의 IImageAnalysisService를 사용하여 이미지를 분석할 수 있는 ImageAnalysisTool을 생성했습니다.
  • MCP 서버를 더 큰 요청을 처리하고 이미지 콘텐츠 유형을 지원하도록 구성했습니다.
  • 이미지 분석 도구를 서버에 등록했습니다.
  • URL에서 이미지를 다운로드하고 요청된 유형(객체, 텍스트, 얼굴 등)에 따라 분석하는 메서드를 구현했습니다.
  • MCP 사양에 맞는 형식으로 구조화된 결과를 반환했습니다.
  • 다중 모달 예제: 오디오 처리

    오디오 처리는 다중 모달 애플리케이션에서 또 다른 일반적인 모달리티입니다. 아래는 오디오 파일을 처리하고 전사를 반환하는 오디오 전사 도구를 구현하는 예제입니다.

    MCP 루트 컨텍스트

    루트 컨텍스트는 Model Context Protocol에서 기본 개념으로, 여러 요청과 세션에 걸쳐 대화 기록과 공유 상태를 지속적으로 유지할 수 있는 계층을 제공합니다.

    소개

    이번 강의에서는 MCP에서 루트 컨텍스트를 생성, 관리 및 활용하는 방법을 살펴봅니다.

    학습 목표

    이 강의를 마치면 다음을 할 수 있습니다:

  • 루트 컨텍스트의 목적과 구조 이해
  • MCP 클라이언트 라이브러리를 사용해 루트 컨텍스트 생성 및 관리
  • .NET, Java, JavaScript, Python 애플리케이션에서 루트 컨텍스트 구현
  • 다중 턴 대화 및 상태 관리를 위한 루트 컨텍스트 활용
  • 루트 컨텍스트 관리에 대한 모범 사례 적용
  • 루트 컨텍스트 이해하기

    루트 컨텍스트는 관련된 일련의 상호작용에 대한 기록과 상태를 담는 컨테이너 역할을 합니다. 이를 통해 다음이 가능합니다:

  • 대화 지속성: 일관된 다중 턴 대화 유지
  • 메모리 관리: 상호작용 간 정보 저장 및 조회
  • 상태 관리: 복잡한 워크플로우 진행 상황 추적
  • 컨텍스트 공유: 여러 클라이언트가 동일한 대화 상태에 접근 가능
  • MCP에서 루트 컨텍스트는 다음과 같은 주요 특징을 가집니다:

  • 각 루트 컨텍스트는 고유 식별자를 가집니다.
  • 대화 기록, 사용자 선호도, 기타 메타데이터를 포함할 수 있습니다.
  • 필요에 따라 생성, 접근, 보관할 수 있습니다.
  • 세밀한 접근 제어 및 권한을 지원합니다.
  • 루트 컨텍스트 수명 주기

    위 코드에서는:

    1. 고객 지원 세션을 위한 루트 컨텍스트를 생성했습니다.

    2. 해당 컨텍스트 내에서 여러 메시지를 보내 모델이 상태를 유지하도록 했습니다.

    3. 대화에 기반해 관련 메타데이터로 컨텍스트를 업데이트했습니다.

    4. 대화 기록을 이해하기 위해 컨텍스트 정보를 조회했습니다.

    5. 대화가 완료되면 컨텍스트를 보관했습니다.

    위 코드에서는:

    1. 금융 분석 세션을 위한 루트 컨텍스트를 생성했습니다.

    2. 해당 컨텍스트 내에서 여러 메시지를 보내 모델이 상태를 유지하도록 했습니다.

    3. 대화에 기반해 관련 메타데이터로 컨텍스트를 업데이트했습니다.

    4. 분석 세션 요약을 생성하여 컨텍스트 메타데이터에 저장했습니다.

    5. 대화가 완료되면 컨텍스트를 보관했습니다.

    예시: 루트 컨텍스트 관리

    루트 컨텍스트를 효과적으로 관리하는 것은 대화 기록과 상태 유지를 위해 매우 중요합니다. 아래는 루트 컨텍스트 관리를 구현하는 예시입니다.

        response2 = await assistant.send_message(
    
            context_id,
    
            "Yes, I've already checked the configuration settings you mentioned, but it's still not working."
    
        )
    
        print(f"Response 2: {response2.generated_text}")
    
        
    
        # 3. Get history
    
        history = await assistant.get_conversation_history(context_id)
    
        print(f"Session has {len(history['messages'])} messages")
    
        
    
        # 4. End session
    
        end_result = await assistant.end_session(context_id)
    
        print(f"Session ended with summary: {end_result['summary']}")

    위 코드에서는:

    1. create_session 함수를 사용해 이름과 기술 수준 같은 사용자 정보를 포함한 기술 지원 세션용 루트 컨텍스트를 생성했습니다.

    2. send_message 함수를 통해 자동 확장 기능 문제에 관한 여러 메시지를 보내 모델이 상태를 유지하도록 했습니다.

    3. get_conversation_history 함수를 사용해 대화 기록과 메시지 등 컨텍스트 정보를 조회했습니다.

    4. end_session 함수를 통해 컨텍스트를 보관하고 대화 요약을 생성해 주요 내용을 캡처하며 세션을 종료했습니다.

    루트 컨텍스트 모범 사례

    루트 컨텍스트를 효과적으로 관리하기 위한 모범 사례는 다음과 같습니다:

  • 목적에 맞는 컨텍스트 생성: 명확성을 위해 대화 목적이나 도메인별로 별도의 루트 컨텍스트를 만드세요.
  • 만료 정책 설정: 저장 공간 관리와 데이터 보존 정책 준수를 위해 오래된 컨텍스트를 보관하거나 삭제하는 정책을 구현하세요.
  • 관련 메타데이터 저장: 나중에 유용할 수 있는 중요한 대화 정보를 컨텍스트 메타데이터에 저장하세요.
  • 컨텍스트 ID 일관성 유지: 컨텍스트가 생성되면 관련 요청에 대해 해당 ID를 일관되게 사용해 연속성을 유지하세요.
  • 요약 생성: 컨텍스트가 커질 경우 핵심 정보를 담은 요약을 생성해 컨텍스트 크기를 관리하세요.
  • 접근 제어 구현: 다중 사용자 시스템에서는 대화 컨텍스트의 프라이버시와 보안을 위해 적절한 접근 제어를 적용하세요.
  • 컨텍스트 한계 관리: 컨텍스트 크기 제한을 인지하고 매우 긴 대화를 처리할 전략을 마련하세요.
  • 완료 시 보관: 대화가 끝나면 컨텍스트를 보관해 리소스를 확보하면서 대화 기록을 보존하세요.

    MCP의 샘플링 및 라우팅 아키텍처

    샘플링은 Model Context Protocol(MCP)의 핵심 요소로, 효율적인 요청 처리와 라우팅을 가능하게 합니다. 이는 들어오는 요청을 분석하여 콘텐츠 유형, 사용자 컨텍스트, 시스템 부하 등 다양한 기준에 따라 가장 적합한 모델이나 서비스로 처리하도록 결정하는 과정을 포함합니다.

    샘플링과 라우팅을 결합하면 자원 활용을 최적화하고 높은 가용성을 보장하는 견고한 아키텍처를 만들 수 있습니다. 샘플링 과정은 요청을 분류하는 데 사용되며, 라우팅은 이를 적절한 모델이나 서비스로 전달합니다.

    모델 컨텍스트 프로토콜에서의 샘플링

    샘플링은 서버가 클라이언트를 통해 LLM 완성을 요청할 수 있게 하는 강력한 MCP 기능으로, 보안과 프라이버시를 유지하면서 정교한 에이전트 행동을 가능하게 합니다. 적절한 샘플링 설정은 응답 품질과 성능을 크게 향상시킬 수 있습니다. MCP는 무작위성, 창의성, 일관성에 영향을 주는 특정 매개변수를 통해 모델이 텍스트를 생성하는 방식을 표준화된 방법으로 제어합니다.

    소개

    이번 강의에서는 MCP 요청에서 샘플링 매개변수를 설정하는 방법과 샘플링의 기본 프로토콜 메커니즘을 살펴봅니다.

    학습 목표

    이 강의를 마치면 다음을 할 수 있습니다:

  • MCP에서 제공하는 주요 샘플링 매개변수를 이해한다.
  • 다양한 사용 사례에 맞게 샘플링 매개변수를 구성한다.
  • 재현 가능한 결과를 위한 결정론적 샘플링을 구현한다.
  • 상황과 사용자 선호도에 따라 샘플링 매개변수를 동적으로 조정한다.
  • 다양한 시나리오에서 모델 성능 향상을 위한 샘플링 전략을 적용한다.
  • MCP의 클라이언트-서버 흐름에서 샘플링이 어떻게 작동하는지 이해한다.
  • MCP에서 샘플링 작동 방식

    MCP의 샘플링 흐름은 다음과 같습니다:

    1. 서버가 클라이언트에 sampling/createMessage 요청을 보냄

    2. 클라이언트가 요청을 검토하고 수정 가능

    3. 클라이언트가 LLM에서 샘플링 수행

    4. 클라이언트가 완성 결과를 검토

    5. 클라이언트가 결과를 서버에 반환

    이 인간 개입형 설계는 사용자가 LLM이 보는 내용과 생성하는 내용을 직접 제어할 수 있도록 보장합니다.

    샘플링 매개변수 개요

    MCP는 클라이언트 요청에서 설정할 수 있는 다음과 같은 샘플링 매개변수를 정의합니다:

    매개변수 설명 일반 범위 ----------- ------------- --------------- temperature 토큰 선택의 무작위성 제어 0.0 - 1.0 maxTokens 생성할 최대 토큰 수 정수 값 stopSequences 생성 중단을 유발하는 사용자 정의 시퀀스 문자열 배열 metadata 추가 제공자별 매개변수 JSON 객체

    많은 LLM 제공자는 metadata 필드를 통해 다음과 같은 추가 매개변수를 지원합니다:

    일반 확장 매개변수 설명 일반 범위 ----------- ------------- --------------- top_p 누클리어스 샘플링 - 누적 확률 상위 토큰으로 제한 0.0 - 1.0 top_k 토큰 선택을 상위 K개 옵션으로 제한 1 - 100 presence_penalty 이미 등장한 토큰에 대한 페널티 부여 -2.0 - 2.0 frequency_penalty 토큰 빈도에 따른 페널티 부여 -2.0 - 2.0 seed 재현 가능한 결과를 위한 고정 랜덤 시드 정수 값

    요청 예시 형식

    다음은 MCP에서 클라이언트에 샘플링을 요청하는 예시입니다:

    
    {
    
      "method": "sampling/createMessage",
    
      "params": {
    
        "messages": [
    
          {
    
            "role": "user",
    
            "content": {
    
              "type": "text",
    
              "text": "What files are in the current directory?"
    
            }
    
          }
    
        ],
    
        "systemPrompt": "You are a helpful file system assistant.",
    
        "includeContext": "thisServer",
    
        "maxTokens": 100,
    
        "temperature": 0.7
    
      }
    
    }
    
    

    응답 형식

    클라이언트는 완성 결과를 반환합니다:

    
    {
    
      "model": "string",  // Name of the model used
    
      "stopReason": "endTurn" | "stopSequence" | "maxTokens" | "string",
    
      "role": "assistant",
    
      "content": {
    
        "type": "text",
    
        "text": "string"
    
      }
    
    }
    
    

    인간 개입형 제어

    MCP 샘플링은 인간 감독을 염두에 두고 설계되었습니다:

  • 프롬프트에 대해:
  • - 클라이언트는 사용자에게 제안된 프롬프트를 보여야 합니다.

    - 사용자는 프롬프트를 수정하거나 거부할 수 있어야 합니다.

    - 시스템 프롬프트는 필터링하거나 수정할 수 있습니다.

    - 컨텍스트 포함 여부는 클라이언트가 제어합니다.

  • 완성에 대해:
  • - 클라이언트는 사용자에게 완성 결과를 보여야 합니다.

    - 사용자는 완성 결과를 수정하거나 거부할 수 있어야 합니다.

    - 클라이언트는 완성 결과를 필터링하거나 수정할 수 있습니다.

    - 사용자가 사용할 모델을 선택할 수 있습니다.

    이 원칙을 바탕으로, 다양한 프로그래밍 언어에서 공통적으로 지원되는 매개변수에 초점을 맞춰 샘플링 구현 방법을 살펴봅니다.

    보안 고려사항

    MCP에서 샘플링을 구현할 때 다음 보안 모범 사례를 고려하세요:

  • 클라이언트에 보내기 전 모든 메시지 내용을 검증합니다.
  • 프롬프트와 완성에서 민감한 정보를 정제합니다.
  • 남용 방지를 위한 속도 제한을 구현합니다.
  • 비정상적인 샘플링 사용 패턴을 모니터링합니다.
  • 안전한 프로토콜을 사용해 전송 중 데이터를 암호화합니다.
  • 관련 규정에 따라 사용자 데이터 프라이버시를 처리합니다.
  • 준수 및 보안을 위해 샘플링 요청을 감사합니다.
  • 적절한 제한으로 비용 노출을 통제합니다.
  • 샘플링 요청에 타임아웃을 설정합니다.
  • 모델 오류 발생 시 적절한 대체 방안을 마련합니다.
  • 샘플링 매개변수는 결정론적 출력과 창의적 출력을 적절히 조절할 수 있도록 모델 동작을 미세 조정할 수 있게 합니다.

    다음으로 다양한 프로그래밍 언어에서 이 매개변수를 설정하는 방법을 살펴보겠습니다.

    .NET

    
    // .NET Example: Configuring sampling parameters in MCP
    
    public class SamplingExample
    
    {
    
        public async Task RunWithSamplingAsync()
    
        {
    
            // Create MCP client with sampling configuration
    
            var client = new McpClient("https://mcp-server-url.com");
    
            
    
            // Create request with specific sampling parameters
    
            var request = new McpRequest
    
            {
    
                Prompt = "Generate creative ideas for a mobile app",
    
                SamplingParameters = new SamplingParameters
    
                {
    
                    Temperature = 0.8f,     // Higher temperature for more creative outputs
    
                    TopP = 0.95f,           // Nucleus sampling parameter
    
                    TopK = 40,              // Limit token selection to top K options
    
                    FrequencyPenalty = 0.5f, // Reduce repetition
    
                    PresencePenalty = 0.2f   // Encourage diversity
    
                },
    
                AllowedTools = new[] { "ideaGenerator", "marketAnalyzer" }
    
            };
    
            
    
            // Send request using specific sampling configuration
    
            var response = await client.SendRequestAsync(request);
    
            
    
            // Output results
    
            Console.WriteLine($"Generated with Temperature={request.SamplingParameters.Temperature}:");
    
            Console.WriteLine(response.GeneratedText);
    
        }
    
    }
    
    

    위 코드에서는:

  • 특정 서버 URL로 MCP 클라이언트를 생성했습니다.
  • temperature, top_p, top_k 같은 샘플링 매개변수를 포함한 요청을 구성했습니다.
  • 요청을 보내고 생성된 텍스트를 출력했습니다.
  • 다음을 사용했습니다:
  • - allowedTools로 모델이 생성 중 사용할 수 있는 도구를 지정했습니다.

    여기서는 ideaGeneratormarketAnalyzer 도구를 허용해 창의적인 앱 아이디어 생성에 도움을 주었습니다.

    - frequencyPenaltypresencePenalty로 출력의 반복성과 다양성을 제어했습니다.

    - temperature로 출력의 무작위성을 조절했으며, 값이 높을수록 더 창의적인 응답이 생성됩니다.

    - top_p로 누적 확률 상위 토큰만 선택하도록 제한해 생성 텍스트 품질을 향상시켰습니다.

    - top_k로 모델이 상위 K개의 가장 가능성 높은 토큰만 선택하도록 제한해 더 일관된 응답을 생성하도록 했습니다.

    - frequencyPenaltypresencePenalty를 사용해 반복을 줄이고 다양성을 촉진했습니다.

      // Configure request with different sampling parameters
    
      const creativeSampling = {
    
        temperature: 0.9,    // Higher temperature = more randomness/creativity

      }
    
    }
    
    
    
    demonstrateSampling();
    
    

    위 코드에서는:

  • 서버 URL과 API 키로 MCP 클라이언트를 초기화했습니다.
  • 창의적 작업과 사실적 작업을 위한 두 가지 샘플링 매개변수 세트를 구성했습니다.
  • 각 구성으로 요청을 보내고, 모델이 각 작업에 맞는 특정 도구를 사용하도록 허용했습니다.
  • 생성된 응답을 출력해 다양한 샘플링 매개변수의 효과를 보여주었습니다.
  • allowedTools로 모델이 생성 중 사용할 수 있는 도구를 지정했습니다. 창의적 작업에는 ideaGeneratorenvironmentalImpactTool을, 사실적 작업에는 factCheckerdataAnalysisTool을 허용했습니다.
  • temperature로 출력의 무작위성을 조절했으며, 값이 높을수록 더 창의적인 응답이 생성됩니다.
  • top_p로 누적 확률 상위 토큰만 선택하도록 제한해 생성 텍스트 품질을 향상시켰습니다.
  • frequencyPenaltypresencePenalty로 반복을 줄이고 다양성을 촉진했습니다.
  • top_k로 모델이 상위 K개의 가장 가능성 높은 토큰만 선택하도록 제한해 더 일관된 응답을 생성하도록 했습니다.

    결정론적 샘플링

    일관된 출력을 요구하는 애플리케이션에서는 결정론적 샘플링이 재현 가능한 결과를 보장합니다. 이는 고정된 랜덤 시드를 사용하고 온도를 0으로 설정함으로써 구현됩니다.

    다음은 다양한 프로그래밍 언어에서 결정론적 샘플링을 시연하는 예시입니다.

    Java

    
    // Java Example: Deterministic responses with fixed seed
    
    public class DeterministicSamplingExample {
    
        public void demonstrateDeterministicResponses() {
    
            McpClient client = new McpClient.Builder()
    
                .setServerUrl("https://mcp-server-example.com")
    
                .build();
    
                
    
            long fixedSeed = 12345; // Using a fixed seed for deterministic results
    
            
    
            // First request with fixed seed
    
            McpRequest request1 = new McpRequest.Builder()
    
                .setPrompt("Generate a random number between 1 and 100")

    위 코드에서는:

  • 지정된 서버 URL로 MCP 클라이언트를 생성했습니다.
  • 동일한 프롬프트, 고정 시드, 온도 0으로 두 개의 요청을 구성했습니다.
  • 두 요청을 보내고 생성된 텍스트를 출력했습니다.
  • 샘플링 설정(같은 시드와 온도) 덕분에 응답이 동일함을 보여주었습니다.
  • setSeed를 사용해 고정 랜덤 시드를 지정해 동일 입력에 대해 항상 같은 출력을 생성하도록 했습니다.
  • temperature를 0으로 설정해 최대한 결정론적으로, 즉 무작위성 없이 가장 가능성 높은 다음 토큰을 항상 선택하도록 했습니다.

    동적 샘플링 구성

    지능형 샘플링은 각 요청의 상황과 요구에 따라 매개변수를 조정합니다.

    즉, 작업 유형, 사용자 선호도, 과거 성과에 따라 temperature, top_p, 페널티 등을 동적으로 변경합니다.

    다음은 다양한 프로그래밍 언어에서 동적 샘플링을 구현하는 방법입니다.

    위 코드에서는:

  • 적응형 샘플링을 관리하는 DynamicSamplingService 클래스를 만들었습니다.
  • 창의적, 사실적, 코드, 분석 작업 유형별 샘플링 프리셋을 정의했습니다.
  • 작업 유형에 따라 기본 샘플링 프리셋을 선택했습니다.
  • 사용자 선호도(창의성 수준, 다양성 등)에 따라 샘플링 매개변수를 조정했습니다.
  • 동적으로 구성된 샘플링 매개변수로 요청을 보냈습니다.
  • 생성된 텍스트와 적용된 샘플링 매개변수, 작업 유형을 함께 반환했습니다.
  • temperature로 출력 무작위성을 조절해 값이 높을수록 더 창의적인 응답을 생성했습니다.
  • top_p로 누적 확률 상위 토큰만 선택하도록 제한해 생성 텍스트 품질을 향상시켰습니다.
  • frequency_penalty로 반복을 줄이고 다양성을 촉진했습니다.
  • user_preferences를 사용해 사용자 정의 창의성 및 다양성 수준에 따라 샘플링 매개변수를 맞춤 설정했습니다.
  • task_type을 사용해 요청에 적합한 샘플링 전략을 결정해 작업 특성에 맞는 응답을 가능하게 했습니다.
  • send_request 메서드로 구성된 샘플링 매개변수와 함께 프롬프트를 보내 모델이 요구사항에 맞게 텍스트를 생성하도록 했습니다.
  • generated_text로 모델 응답을 받아 샘플링 매개변수 및 작업 유형과 함께 반환해 투명성을 높였습니다.
  • minmax 함수를 사용해 사용자 선호도가 유효 범위 내에 있도록 제한했습니다.

    확장성 및 고성능 MCP

    기업 환경에서 MCP 구현은 종종 최소한의 지연 시간으로 대량의 요청을 처리해야 합니다.

    소개

    이번 강의에서는 대규모 작업 부하를 효율적으로 처리하기 위한 MCP 서버 확장 전략을 살펴봅니다. 수평 및 수직 확장, 자원 최적화, 분산 아키텍처에 대해 다룹니다.

    학습 목표

    이 강의를 마치면 다음을 수행할 수 있습니다:

  • 로드 밸런싱과 분산 캐싱을 활용한 수평 확장 구현.
  • 수직 확장 및 자원 관리를 위한 MCP 서버 최적화.
  • 고가용성과 장애 허용을 위한 분산 MCP 아키텍처 설계.
  • 성능 모니터링 및 최적화를 위한 고급 도구와 기법 활용.
  • 운영 환경에서 MCP 서버 확장을 위한 모범 사례 적용.
  • 확장 전략

    MCP 서버를 효과적으로 확장하기 위한 여러 전략이 있습니다:

  • 수평 확장: 로드 밸런서 뒤에 여러 MCP 서버 인스턴스를 배포하여 들어오는 요청을 고르게 분산합니다.
  • 수직 확장: 단일 MCP 서버 인스턴스의 자원(CPU, 메모리)을 늘리고 설정을 세밀하게 조정하여 더 많은 요청을 처리하도록 최적화합니다.
  • 자원 최적화: 효율적인 알고리즘, 캐싱, 비동기 처리를 사용해 자원 소비를 줄이고 응답 시간을 개선합니다.
  • 분산 아키텍처: 여러 MCP 노드가 함께 작동하며 부하를 분산하고 중복성을 제공하는 분산 시스템을 구현합니다.
  • 수평 확장

    수평 확장은 여러 MCP 서버 인스턴스를 배포하고 로드 밸런서를 사용해 들어오는 요청을 분산하는 방식입니다. 이를 통해 동시에 더 많은 요청을 처리할 수 있고 장애 허용성을 제공합니다.

    수평 확장과 MCP 구성 예제를 살펴보겠습니다.

    .NET

    
    // ASP.NET Core MCP load balancing configuration
    
    public class McpLoadBalancedStartup
    
    {
    
        public void ConfigureServices(IServiceCollection services)
    
        {
    
            // Configure distributed cache for session state
    
            services.AddStackExchangeRedisCache(options =>
    
            {
    
                options.Configuration = Configuration.GetConnectionString("RedisConnection");
    
                options.InstanceName = "MCP_";
    
            });
    
            
    
            // Configure MCP with distributed caching
    
            services.AddMcpServer(options =>
    
            {
    
                options.ServerName = "Scalable MCP Server";
    
                options.ServerVersion = "1.0.0";
    
                options.EnableDistributedCaching = true;
    
                options.CacheExpirationMinutes = 60;
    
            });
    
            
    
            // Register tools
    
            services.AddMcpTool<HighPerformanceTool>();
    
        }
    
    }
    
    

    위 코드에서는 다음을 수행했습니다:

  • Redis를 사용해 세션 상태와 도구 데이터를 저장하는 분산 캐시를 구성했습니다.
  • MCP 서버 설정에서 분산 캐싱을 활성화했습니다.
  • 여러 MCP 인스턴스에서 사용할 수 있는 고성능 도구를 등록했습니다.

    수직 확장 및 자원 최적화

    수직 확장은 단일 MCP 서버 인스턴스를 최적화해 더 많은 요청을 효율적으로 처리하는 데 중점을 둡니다. 설정을 세밀하게 조정하고, 효율적인 알고리즘을 사용하며, 자원을 효과적으로 관리하는 방식으로 달성할 수 있습니다. 예를 들어, 스레드 풀, 요청 타임아웃, 메모리 제한을 조정해 성능을 개선할 수 있습니다.

    수직 확장과 자원 관리를 위한 MCP 서버 최적화 예제를 살펴보겠습니다.

    Java

    
    // Java MCP server with resource optimization
    
    public class OptimizedMcpServer {
    
        public static McpServer createOptimizedServer() {
    
            // Configure thread pool for optimal performance
    
            int processors = Runtime.getRuntime().availableProcessors();
    
            int optimalThreads = processors * 2; // Common heuristic for I/O-bound tasks
    
            
    
            ExecutorService executorService = new ThreadPoolExecutor(
    
                processors,       // Core pool size
    
                optimalThreads,   // Maximum pool size 
    
                60L,              // Keep-alive time
    
                TimeUnit.SECONDS,
    
                new ArrayBlockingQueue<>(1000), // Request queue size
    
                new ThreadPoolExecutor.CallerRunsPolicy() // Backpressure strategy
    
            );
    
            
    
            // Configure and build MCP server with resource constraints
    
            return new McpServer.Builder()
    
                .setName("High-Performance MCP Server")
    
                .setVersion("1.0.0")
    
                .setPort(5000)
    
                .setExecutor(executorService)
    
                .setMaxRequestSize(1024 * 1024) // 1MB
    
                .setMaxConcurrentRequests(100)
    
                .setRequestTimeoutMs(5000) // 5 seconds
    
                .build();
    
        }
    
    }
    
    

    위 코드에서는 다음을 수행했습니다:

  • 사용 가능한 프로세서 수에 기반해 최적의 스레드 수로 스레드 풀을 구성했습니다.
  • 최대 요청 크기, 최대 동시 요청 수, 요청 타임아웃과 같은 자원 제한을 설정했습니다.
  • 과부하 상황을 우아하게 처리하기 위해 백프레셔 전략을 사용했습니다.

    분산 아키텍처

    분산 아키텍처는 여러 MCP 노드가 함께 작동해 요청을 처리하고 자원을 공유하며 중복성을 제공합니다. 이 방식은 노드 간 통신과 조정을 통해 확장성과 장애 허용성을 높입니다.

    MCP 보안 모범 사례 - 고급 구현 가이드

    > 현재 표준: 이 가이드는 MCP 사양 2025-06-18의 보안 요구사항과 공식 MCP 보안 모범 사례를 반영합니다.

    보안은 특히 기업 환경에서 MCP 구현에 있어 매우 중요합니다. 이 고급 가이드는 MCP를 프로덕션 환경에 배포할 때 필요한 포괄적인 보안 관행을 탐구하며, 전통적인 보안 문제와 Model Context Protocol에 특화된 AI 관련 위협을 모두 다룹니다.

    소개

    Model Context Protocol (MCP)은 기존 소프트웨어 보안을 넘어서는 독특한 보안 과제를 제시합니다. AI 시스템이 도구, 데이터, 외부 서비스에 접근함에 따라 프롬프트 인젝션, 도구 오염, 세션 하이재킹, 혼란스러운 대리 문제, 토큰 패스스루 취약점과 같은 새로운 공격 벡터가 등장합니다.

    이 강의에서는 최신 MCP 사양(2025-06-18), Microsoft 보안 솔루션, 그리고 확립된 기업 보안 패턴을 기반으로 한 고급 보안 구현을 탐구합니다.

    핵심 보안 원칙

    MCP 사양 (2025-06-18)에서 발췌:

  • 명시적 금지: MCP 서버는 발급되지 않은 토큰을 절대 허용해서는 안 되며, 세션을 인증에 사용해서는 안 됩니다.
  • 필수 검증: 모든 인바운드 요청은 반드시 검증되어야 하며, 프록시 작업에 대해 사용자 동의를 반드시 받아야 합니다.
  • 안전한 기본값: 심층 방어 접근법을 통해 안전한 기본 보안 제어를 구현합니다.
  • 사용자 제어: 사용자는 데이터 접근 또는 도구 실행 전에 명시적 동의를 제공해야 합니다.
  • 학습 목표

    이 고급 강의를 마치면 다음을 수행할 수 있습니다:

  • 고급 인증 구현: Microsoft Entra ID 및 OAuth 2.1 보안 패턴을 활용한 외부 ID 제공자 통합 배포
  • AI 관련 공격 방지: Microsoft Prompt Shields 및 Azure Content Safety를 사용하여 프롬프트 인젝션, 도구 오염, 세션 하이재킹 방지
  • 기업 보안 적용: 프로덕션 MCP 배포를 위한 포괄적인 로깅, 모니터링 및 사고 대응 구현
  • 도구 실행 보안: 적절한 격리 및 리소스 제어를 갖춘 샌드박스 실행 환경 설계
  • MCP 취약점 해결: 혼란스러운 대리 문제, 토큰 패스스루 취약점 및 공급망 위험 식별 및 완화
  • Microsoft 보안 통합: Azure 보안 서비스 및 GitHub Advanced Security를 활용한 포괄적 보호
  • 필수 보안 요구사항

    MCP 사양 (2025-06-18)의 주요 요구사항:

    
    Authentication & Authorization:
    
      token_validation: "MUST NOT accept tokens not issued for MCP server"
    
      session_authentication: "MUST NOT use sessions for authentication"
    
      request_verification: "MUST verify ALL inbound requests"
    
      
    
    Proxy Operations:  
    
      user_consent: "MUST obtain consent for dynamic client registration"
    
      oauth_security: "MUST implement OAuth 2.1 with PKCE"
    
      redirect_validation: "MUST validate redirect URIs strictly"
    
      
    
    Session Management:
    
      session_ids: "MUST use secure, non-deterministic generation" 
    
      user_binding: "SHOULD bind to user-specific information"
    
      transport_security: "MUST use HTTPS for all communications"
    
    

    고급 인증 및 권한 부여

    최신 MCP 구현은 외부 ID 제공자 위임으로의 사양 진화를 통해 맞춤형 인증 구현보다 보안 태세를 크게 개선합니다.

    Microsoft Entra ID 통합

    최신 MCP 사양(2025-06-18)은 Microsoft Entra ID와 같은 외부 ID 제공자에 대한 위임을 허용하여 기업 수준의 보안 기능을 제공합니다:

    보안 혜택:

  • 기업 수준의 다단계 인증(MFA)
  • 위험 평가 기반 조건부 액세스 정책
  • 중앙 집중식 ID 라이프사이클 관리
  • 고급 위협 보호 및 이상 탐지
  • 기업 보안 표준 준수
  • .NET과 Entra ID를 활용한 구현

    이 섹션에서는 웹 검색 MCP 서버의 아키텍처와 기능을 소개합니다. FastMCP와 SerpAPI를 함께 사용해 실시간 웹 데이터로 LLM 기능을 확장하는 방법을 살펴봅니다.

    개요

    이 구현은 MCP가 다양한 외부 API 기반 작업을 안전하고 효율적으로 처리할 수 있음을 보여주는 네 가지 도구를 포함합니다:

  • general_search: 광범위한 웹 검색용
  • news_search: 최신 뉴스 헤드라인용
  • product_search: 전자상거래 데이터용
  • qna: 질문과 답변 스니펫용
  • 특징

  • 코드 예제: Python용 언어별 코드 블록 포함 (다른 언어로도 쉽게 확장 가능), 명확한 이해를 위한 코드 피벗 사용
  • Python

    
    # Example usage of the general_search tool
    
    from mcp import ClientSession, StdioServerParameters
    
    from mcp.client.stdio import stdio_client
    
    
    
    async def run_search():
    
        server_params = StdioServerParameters(
    
            command="python",
    
            args=["server.py"],
    
        )
    
        async with stdio_client(server_params) as (reader, writer):
    
            async with ClientSession(reader, writer) as session:
    
                await session.initialize()
    
                result = await session.call_tool("general_search", arguments={"query": "open source LLMs"})
    
                print(result)
    
    

    ---

    클라이언트를 실행하기 전에 서버가 하는 일을 이해하는 것이 도움이 됩니다. server.py 파일은 MCP 서버를 구현하며, SerpAPI와 통합해 웹, 뉴스, 상품 검색, Q&A 도구를 제공합니다.

    들어오는 요청을 처리하고, API 호출을 관리하며, 응답을 파싱해 구조화된 결과를 클라이언트에 반환합니다.

    전체 구현은 server.py에서 확인할 수 있습니다.

    아래는 서버가 도구를 정의하고 등록하는 간단한 예시입니다:

    Python 서버

    
    # server.py (excerpt)
    
    from mcp.server import MCPServer, Tool
    
    
    
    async def general_search(query: str):
    
        # ...implementation...
    
    
    
    server = MCPServer()
    
    server.add_tool(Tool("general_search", general_search))
    
    
    
    if __name__ == "__main__":
    
        server.run()
    
    

    ---

  • 외부 API 통합: API 키와 외부 요청을 안전하게 처리하는 방법 시연
  • 구조화된 데이터 파싱: API 응답을 LLM 친화적인 형식으로 변환하는 방법
  • 오류 처리: 적절한 로깅과 함께 견고한 오류 처리 구현
  • 대화형 클라이언트: 자동화 테스트와 대화형 모드 모두 포함
  • 컨텍스트 관리: MCP Context를 활용해 로깅 및 요청 추적 수행
  • 사전 준비 사항

    시작하기 전에 환경이 올바르게 설정되었는지 확인하세요. 이 단계는 모든 의존성이 설치되고 API 키가 올바르게 구성되어 원활한 개발과 테스트가 가능하도록 합니다.

  • Python 3.8 이상
  • SerpAPI API 키 (가입은 SerpAPI에서 - 무료 플랜 제공)
  • 설치

    환경 설정을 위해 다음 단계를 따르세요:

    1. uv(권장) 또는 pip로 의존성 설치:

    
    # Using uv (recommended)
    
    uv pip install -r requirements.txt
    
    
    
    # Using pip
    
    pip install -r requirements.txt
    
    

    2. 프로젝트 루트에 .env 파일을 만들고 SerpAPI 키를 추가:

    
    SERPAPI_KEY=your_serpapi_key_here
    
    

    사용법

    웹 검색 MCP 서버는 SerpAPI와 통합해 웹, 뉴스, 상품 검색, Q&A 도구를 제공하는 핵심 컴포넌트입니다. 들어오는 요청을 처리하고, API 호출을 관리하며, 응답을 파싱해 구조화된 결과를 클라이언트에 반환합니다.

    전체 구현은 server.py에서 확인할 수 있습니다.

    서버 실행

    MCP 서버를 시작하려면 다음 명령어를 사용하세요:

    
    python server.py
    
    

    서버는 stdio 기반 MCP 서버로 실행되며, 클라이언트가 직접 연결할 수 있습니다.

    클라이언트 모드

    클라이언트(client.py)는 MCP 서버와 상호작용할 수 있는 두 가지 모드를 지원합니다:

  • 일반 모드: 모든 도구를 자동으로 테스트하고 응답을 검증합니다. 서버와 도구가 정상 작동하는지 빠르게 확인할 때 유용합니다.
  • 대화형 모드: 메뉴 기반 인터페이스를 시작해 도구를 수동으로 선택하고 호출하며, 직접 쿼리를 입력하고 실시간으로 결과를 확인할 수 있습니다. 서버 기능을 탐색하고 다양한 입력을 실험할 때 적합합니다.
  • 전체 구현은 client.py에서 확인할 수 있습니다.

    클라이언트 실행

    자동화 테스트 실행 (서버도 자동 시작됨):

    
    python client.py
    
    

    또는 대화형 모드 실행:

    
    python client.py --interactive
    
    

    다양한 방법으로 테스트하기

    필요와 작업 흐름에 따라 서버가 제공하는 도구를 테스트하고 상호작용하는 여러 방법이 있습니다.

    MCP Python SDK로 맞춤 테스트 스크립트 작성하기

    MCP Python SDK를 사용해 직접 테스트 스크립트를 만들 수도 있습니다:

    Python

    
    from mcp import ClientSession, StdioServerParameters
    
    from mcp.client.stdio import stdio_client
    
    
    
    async def test_custom_query():
    
        server_params = StdioServerParameters(
    
            command="python",
    
            args=["server.py"],
    
        )
    
        
    
        async with stdio_client(server_params) as (reader, writer):
    
            async with ClientSession(reader, writer) as session:
    
                await session.initialize()
    
                # Call tools with your custom parameters
    
                result = await session.call_tool("general_search", 
    
                                               arguments={"query": "your custom query"})
    
                # Process the result
    
    

    ---

    여기서 "테스트 스크립트"란 MCP 서버의 클라이언트 역할을 하는 맞춤 Python 프로그램을 의미합니다. 정식 단위 테스트가 아니라, 프로그래밍 방식으로 서버에 연결해 원하는 도구를 호출하고 결과를 확인할 수 있습니다. 이 방법은 다음에 유용합니다:

  • 도구 호출 프로토타입 제작 및 실험
  • 서버가 다양한 입력에 어떻게 반응하는지 검증
  • 반복적인 도구 호출 자동화
  • MCP 서버 위에 자신만의 워크플로우나 통합 구축
  • 테스트 스크립트를 사용해 새 쿼리를 빠르게 시도하거나 도구 동작을 디버깅할 수 있으며, 더 고급 자동화의 출발점으로도 활용할 수 있습니다. 아래는 MCP Python SDK를 사용해 스크립트를 만드는 예시입니다:

  • 이 섹션은 웹 검색 MCP 서버 작업 중 마주칠 수 있는 일반적인 문제를 진단하고 해결하는 데 도움을 줍니다. 오류나 예상치 못한 동작이 발생하면 이 문제 해결 섹션을 먼저 확인하세요. 대부분의 문제는 여기서 제시하는 팁으로 빠르게 해결할 수 있습니다.

    문제 해결

    웹 검색 MCP 서버를 사용하다 보면 가끔 문제가 발생할 수 있습니다. 외부 API와 새로운 도구를 다룰 때는 흔한 일입니다. 이 섹션에서는 가장 흔한 문제에 대한 실용적인 해결책을 제공합니다. 문제가 생기면 여기서부터 시작하세요. 아래 팁들은 대부분의 사용자가 겪는 문제를 다루며, 추가 도움 없이도 문제를 해결할 수 있는 경우가 많습니다.

    자주 발생하는 문제

    아래는 사용자들이 자주 겪는 문제와 그에 대한 명확한 설명 및 해결 방법입니다:

    1. .env 파일에 SERPAPI_KEY 누락

    - SERPAPI_KEY environment variable not found 오류가 나타나면, 애플리케이션이 SerpAPI 접근에 필요한 API 키를 찾지 못하는 것입니다.

    이를 해결하려면 프로젝트 루트에 .env 파일을 만들고 SERPAPI_KEY=your_serpapi_key_here 형식으로 키를 추가하세요. your_serpapi_key_here는 SerpAPI 웹사이트에서 받은 실제 키로 바꿔야 합니다.

    2. 모듈을 찾을 수 없다는 오류

    - ModuleNotFoundError: No module named 'httpx' 같은 오류는 필요한 Python 패키지가 설치되지 않았을 때 발생합니다.

    보통 의존성을 모두 설치하지 않았을 때 나타납니다.

    터미널에서 pip install -r requirements.txt를 실행해 프로젝트에 필요한 모든 패키지를 설치하세요.

    3. 연결 문제

    - Error during client execution 같은 오류는 클라이언트가 서버에 연결하지 못하거나 서버가 정상적으로 실행되지 않을 때 발생합니다.

    클라이언트와 서버가 호환되는 버전인지, server.py가 올바른 디렉터리에 있고 실행 중인지 확인하세요.

    서버와 클라이언트를 모두 재시작하는 것도 도움이 됩니다.

    4. SerpAPI 오류

    - Search API returned error status: 401 오류는 SerpAPI 키가 없거나 잘못되었거나 만료되었음을 의미합니다.

    SerpAPI 대시보드에서 키를 확인하고 .env 파일을 업데이트하세요.

    키가 올바른데도 오류가 계속되면 무료 플랜의 할당량이 소진되었는지 확인하세요.

    디버그 모드

    기본적으로 앱은 중요한 정보만 로깅합니다. 문제를 진단하거나 자세한 내부 동작을 보고 싶다면 DEBUG 모드를 활성화할 수 있습니다. 이 모드는 앱이 수행하는 각 단계에 대한 더 많은 정보를 보여줍니다.

    2025-06-01 10:15:23,456 - __main__ - INFO - Calling general_search with params: {'query': 'open source LLMs'}
    
    2025-06-01 10:15:24,123 - __main__ - INFO - Successfully called general_search
    
    
    
    GENERAL_SEARCH RESULTS:
    
    ... (search results here) ...
    
    

    예시: DEBUG 출력

    
    2025-06-01 10:15:23,456 - __main__ - INFO - Calling general_search with params: {'query': 'open source LLMs'}
    
    2025-06-01 10:15:23,457 - httpx - DEBUG - HTTP Request: GET https://serpapi.com/search ...
    
    2025-06-01 10:15:23,458 - httpx - DEBUG - HTTP Response: 200 OK ...
    
    2025-06-01 10:15:24,123 - __main__ - INFO - Successfully called general_search
    
    
    
    GENERAL_SEARCH RESULTS:
    
    ... (search results here) ...
    
    

    DEBUG 모드에서는 HTTP 요청, 응답 및 기타 내부 세부 정보가 추가로 출력됩니다. 문제 해결에 매우 유용합니다.

    DEBUG 모드를 활성화하려면 client.py 또는 server.py 상단에서 로깅 레벨을 DEBUG로 설정하세요:

    Python

    
    # At the top of your client.py or server.py
    
    import logging
    
    logging.basicConfig(
    
        level=logging.DEBUG,  # Change from INFO to DEBUG
    
        format="%(asctime)s - %(name)s - %(levelname)s - %(message)s"
    
    )

    이 모듈은 MCP가 AI 모델, 스트리밍 플랫폼, 애플리케이션 전반에 걸친 컨텍스트 관리를 표준화된 접근법으로 제공함으로써 실시간 데이터 스트리밍을 어떻게 혁신하는지 살펴봅니다.

    실시간 데이터 스트리밍 소개

    실시간 데이터 스트리밍은 데이터가 생성됨과 동시에 지속적으로 전송, 처리 및 분석할 수 있게 하는 기술적 패러다임으로, 시스템이 새로운 정보에 즉시 반응할 수 있도록 합니다. 정적 데이터셋을 대상으로 하는 전통적 배치 처리와 달리, 스트리밍은 이동 중인 데이터를 처리하여 지연 시간을 최소화하며 인사이트와 조치를 제공합니다.

    실시간 데이터 스트리밍의 핵심 개념:

  • 지속적인 데이터 흐름: 데이터가 계속해서 이벤트나 레코드의 끊임없는 스트림으로 처리됨
  • 저지연 처리: 데이터 생성과 처리 사이의 시간을 최소화
  • 확장성: 다양한 데이터 양과 속도를 처리할 수 있는 스트리밍 아키텍처
  • 내결함성: 데이터 흐름이 중단되지 않도록 장애에 강한 시스템
  • 상태 유지 처리: 의미 있는 분석을 위해 이벤트 간 컨텍스트 유지 중요
  • 모델 컨텍스트 프로토콜과 실시간 스트리밍

    모델 컨텍스트 프로토콜(MCP)은 실시간 스트리밍 환경의 여러 주요 문제를 해결합니다:

    1. 컨텍스트 연속성: MCP는 분산된 스트리밍 구성 요소 간 컨텍스트 유지 방식을 표준화하여 AI 모델과 처리 노드가 관련된 과거 및 환경적 컨텍스트에 접근하도록 보장합니다.

    MCP가 실시간 데이터 처리에서 개선하는 점

    MCP는 전통적 스트리밍 문제를 다음과 같이 해결합니다:

  • 컨텍스트 무결성: 데이터 포인트 간 관계를 파이프라인 전체에 걸쳐 유지
  • 최적화된 전송: 지능적 컨텍스트 관리를 통해 데이터 중복 감소
  • 표준화된 인터페이스: 스트리밍 구성 요소를 위한 일관된 API 제공
  • 지연 감소: 효율적 컨텍스트 처리로 오버헤드 최소화
  • 확장성 강화: 컨텍스트 유지와 함께 수평 확장 지원
  • 통합 및 구현

    실시간 데이터 스트리밍 시스템은 성능과 컨텍스트 무결성을 모두 유지하기 위해 신중한 아키텍처 설계와 구현이 필요합니다. 모델 컨텍스트 프로토콜은 AI 모델과 스트리밍 기술 통합을 위한 표준화된 접근 방식을 제공하여 더 정교하고 컨텍스트 인식이 가능한 처리 파이프라인을 구축할 수 있게 합니다.

    스트리밍 아키텍처에서 MCP 통합 개요

    실시간 스트리밍 환경에 MCP를 구현할 때 고려할 주요 사항:

    1. 컨텍스트 직렬화 및 전송: MCP는 스트리밍 데이터 패킷 내에 컨텍스트 정보를 효율적으로 인코딩하는 메커니즘을 제공하여 필수 컨텍스트가 데이터와 함께 전체 처리 파이프라인을 따라 이동하도록 보장합니다. 여기에는 스트리밍 전송에 최적화된 표준화된 직렬화 포맷이 포함됩니다.

    2. 상태 유지 스트림 처리: MCP는 처리 노드 전반에 걸쳐 일관된 컨텍스트 표현을 유지하며 더 지능적인 상태 유지 처리를 가능하게 합니다. 이는 전통적으로 상태 관리가 어려운 분산 스트리밍 아키텍처에서 특히 중요합니다.

    3. 이벤트 시간 대비 처리 시간: MCP 구현체는 이벤트 발생 시점과 처리 시점 간의 차이를 다루어야 하는 일반적 문제에 대응할 수 있습니다. 프로토콜은 이벤트 시간 의미를 보존하는 시간 컨텍스트를 포함할 수 있습니다.

    4. 백프레셔 관리: MCP는 컨텍스트 처리를 표준화함으로써 스트리밍 시스템 내 백프레셔를 관리할 수 있도록 돕고, 구성 요소들이 처리 능력을 소통하며 흐름을 조절할 수 있게 합니다.

    5. 컨텍스트 윈도잉 및 집계: MCP는 시간 및 관계적 컨텍스트의 구조화된 표현을 제공하여 이벤트 스트림 간 더 의미 있는 집계를 가능하게 하는 고급 윈도잉 작업을 지원합니다.

    6. 정확히 한 번 처리: 정확히 한 번 처리 의미론이 요구되는 스트리밍 시스템에서는 MCP가 처리 상태 추적 및 검증을 위한 메타데이터를 통합할 수 있습니다.

    다양한 스트리밍 기술에 MCP를 구현함으로써 컨텍스트 관리를 위한 통합된 접근법이 만들어지며 맞춤형 통합 코드를 줄이고 데이터가 파이프라인을 통과할 때 의미 있는 컨텍스트를 유지할 수 있는 시스템 능력을 강화합니다.

    다양한 데이터 스트리밍 프레임워크에서의 MCP

    다음 예시는 JSON-RPC 기반 프로토콜과 각기 다른 전송 메커니즘에 중점을 둔 현재 MCP 사양을 따릅니다. 코드는 MCP 프로토콜과 완벽하게 호환되면서 Kafka와 Pulsar 같은 스트리밍 플랫폼을 통합하는 맞춤 전송을 구현하는 방법을 보여줍니다.

    이 예시는 MCP 중심의 컨텍스트 인식 기능을 유지하면서 실시간 데이터 처리를 제공하는 스트리밍 플랫폼 통합 방법을 설명합니다. 이 접근법은 2025년 6월 현재 MCP 사양 상태를 정확히 반영합니다.

    핵심 개념

    Model Context Protocol (MCP) 프레임워크

    MCP는 AI 모델, 애플리케이션, 서비스 간에 컨텍스트를 교환하기 위한 표준화된 방식을 제공합니다. 실시간 웹 검색에서는 일관된 다중 턴 검색 경험을 만드는 데 필수적입니다. 주요 구성 요소는 다음과 같습니다:

    1. 클라이언트-서버 아키텍처: MCP는 검색 클라이언트(요청자)와 검색 서버(제공자)를 명확히 분리하여 유연한 배포 모델을 지원합니다.

    2. JSON-RPC 통신: 프로토콜은 JSON-RPC를 사용해 메시지를 교환하며, 웹 기술과 호환되고 다양한 플랫폼에서 쉽게 구현할 수 있습니다.

    3. 컨텍스트 관리: MCP는 여러 상호작용에 걸쳐 검색 컨텍스트를 유지, 업데이트, 활용하는 구조화된 방법을 정의합니다.

    4. 도구 정의: 검색 기능을 명확한 매개변수와 반환값을 가진 표준화된 도구로 노출합니다.

    5. 스트리밍 지원: 결과가 점진적으로 도착하는 실시간 검색에 필수적인 스트리밍 결과를 지원합니다.

    웹 검색 통합 패턴

    MCP를 웹 검색에 통합할 때 다음과 같은 패턴이 나타납니다:

    1. 직접 검색 제공자 통합
    
    graph LR
    
        Client[MCP Client] --> |MCP Request| Server[MCP Server]
    
        Server --> |API Call| SearchAPI[Search API]
    
        SearchAPI --> |Results| Server
    
        Server --> |MCP Response| Client
    
    

    이 패턴에서는 MCP 서버가 하나 이상의 검색 API와 직접 인터페이스하며, MCP 요청을 API별 호출로 변환하고 결과를 MCP 응답 형식으로 포맷합니다.

    2. 컨텍스트 보존을 통한 연합 검색
    
    graph LR
    
        Client[MCP Client] --> |MCP Request| Federation[MCP Federation Layer]
    
        Federation --> |MCP Request 1| Search1[Search Provider 1]
    
        Federation --> |MCP Request 2| Search2[Search Provider 2]
    
        Federation --> |MCP Request 3| Search3[Search Provider 3]
    
        Search1 --> |MCP Response 1| Federation
    
        Search2 --> |MCP Response 2| Federation
    
        Search3 --> |MCP Response 3| Federation
    
        Federation --> |Aggregated MCP Response| Client
    
    

    이 패턴은 여러 MCP 호환 검색 제공자에 검색 쿼리를 분산시키며, 각 제공자는 서로 다른 콘텐츠 유형이나 검색 기능에 특화될 수 있고, 통합된 컨텍스트를 유지합니다.

    3. 컨텍스트 강화 검색 체인
    
    graph LR
    
        Client[MCP Client] --> |Query + Context| Server[MCP Server]
    
        Server --> |1. Query Analysis| NLP[NLP Service]
    
        NLP --> |Enhanced Query| Server
    
        Server --> |2. Search Execution| Search[Search Engine]
    
        Search --> |Raw Results| Server
    
        Server --> |3. Result Processing| Enhancement[Result Enhancement]
    
        Enhancement --> |Enhanced Results| Server
    
        Server --> |Final Results + Updated Context| Client
    
    

    이 패턴은 검색 프로세스를 여러 단계로 나누고 각 단계에서 컨텍스트를 풍부하게 하여 점진적으로 더 관련성 높은 결과를 도출합니다.

    검색 컨텍스트 구성 요소

    AI 워크플로우 보안: 모델 컨텍스트 프로토콜 서버용 Entra ID 인증

    소개

    모델 컨텍스트 프로토콜(MCP) 서버를 보호하는 것은 집의 현관문을 잠그는 것만큼 중요합니다.

    MCP 서버를 열어두면 도구와 데이터가 무단 접근에 노출되어 보안 사고로 이어질 수 있습니다.

    Microsoft Entra ID는 강력한 클라우드 기반 아이덴티티 및 접근 관리 솔루션을 제공하여, 권한이 있는 사용자와 애플리케이션만 MCP 서버와 상호작용할 수 있도록 도와줍니다.

    이 섹션에서는 Entra ID 인증을 사용해 AI 워크플로우를 보호하는 방법을 배웁니다.

    학습 목표

    이 섹션을 마치면 다음을 할 수 있습니다:

  • MCP 서버 보안의 중요성을 이해한다.
  • Microsoft Entra ID와 OAuth 2.0 인증의 기본 개념을 설명한다.
  • 공개 클라이언트와 기밀 클라이언트의 차이를 인식한다.
  • 로컬(공개 클라이언트) 및 원격(기밀 클라이언트) MCP 서버 시나리오에서 Entra ID 인증을 구현한다.
  • AI 워크플로우 개발 시 보안 모범 사례를 적용한다.
  • 보안과 MCP

    집의 현관문을 잠그지 않고 두지 않는 것처럼, MCP 서버도 누구나 접근할 수 있도록 열어두면 안 됩니다. AI 워크플로우를 안전하게 보호하는 것은 견고하고 신뢰할 수 있으며 안전한 애플리케이션을 만드는 데 필수적입니다. 이 장에서는 Microsoft Entra ID를 사용해 MCP 서버를 보호하는 방법을 소개하며, 권한이 있는 사용자와 애플리케이션만 도구와 데이터에 접근할 수 있도록 합니다.

    MCP 서버 보안이 중요한 이유

    MCP 서버에 이메일을 보내거나 고객 데이터베이스에 접근할 수 있는 도구가 있다고 가정해 보세요. 보안이 취약한 서버라면 누구나 그 도구를 사용할 수 있어 무단 데이터 접근, 스팸 발송, 기타 악의적 행위가 발생할 수 있습니다.

    인증을 구현하면 서버에 대한 모든 요청이 검증되어 요청을 하는 사용자나 애플리케이션의 신원을 확인할 수 있습니다. 이는 AI 워크플로우 보안의 첫 번째이자 가장 중요한 단계입니다.

    Microsoft Entra ID 소개

    Entra ID를 사용하면 다음이 가능합니다:

  • 사용자에 대한 안전한 로그인 지원
  • API 및 서비스 보호
  • 중앙에서 접근 정책 관리
  • MCP 서버의 경우, Entra ID는 서버 기능에 접근할 수 있는 사용자를 관리하는 강력하고 신뢰받는 솔루션을 제공합니다.

    핵심 이해하기: Entra ID 인증 작동 원리

    Entra ID는 OAuth 2.0 같은 오픈 표준을 사용해 인증을 처리합니다. 세부 사항은 복잡할 수 있지만, 핵심 개념은 비유를 통해 쉽게 이해할 수 있습니다.

    OAuth 2.0 간단 소개: 발렛 키

    OAuth 2.0을 자동차 발렛 서비스에 비유해 보세요. 식당에 도착했을 때, 마스터 키를 발렛에게 주지 않고 제한된 권한만 가진 발렛 키를 줍니다. 이 키는 차를 시동 걸고 문을 잠글 수 있지만, 트렁크나 글러브 박스는 열 수 없습니다.

    이 비유에서:

  • 당신사용자입니다.
  • 당신의 차는 도구와 데이터가 있는 MCP 서버입니다.
  • 발렛Microsoft Entra ID입니다.
  • 주차 담당자는 서버에 접근하려는 MCP 클라이언트(애플리케이션)입니다.
  • 발렛 키액세스 토큰입니다.
  • 액세스 토큰은 사용자가 로그인한 후 MCP 클라이언트가 Entra ID로부터 받는 안전한 문자열입니다. 클라이언트는 이 토큰을 매 요청 시 MCP 서버에 제시하며, 서버는 토큰을 검증해 요청이 합법적이고 필요한 권한이 있는지 확인합니다. 이 과정에서 실제 사용자 자격 증명(예: 비밀번호)을 다룰 필요가 없습니다.

    인증 흐름

    실제 과정은 다음과 같습니다:

    
    sequenceDiagram
    
        actor User as 👤 User
    
        participant Client as 🖥️ MCP Client
    
        participant Entra as 🔐 Microsoft Entra ID
    
        participant Server as 🔧 MCP Server
    
    
    
        Client->>+User: Please sign in to continue.
    
        User->>+Entra: Enters credentials (username/password).
    
        Entra-->>Client: Here is your access token.
    
        User-->>-Client: (Returns to the application)
    
    
    
        Client->>+Server: I need to use a tool. Here is my access token.
    
        Server->>+Entra: Is this access token valid?
    
        Entra-->>-Server: Yes, it is.
    
        Server-->>-Client: Token is valid. Here is the result of the tool.
    
    

    Microsoft 인증 라이브러리(MSAL) 소개

    코드 예제를 살펴보기 전에 중요한 구성 요소인 Microsoft 인증 라이브러리(MSAL)를 소개합니다.

    MSAL은 개발자가 인증을 쉽게 처리할 수 있도록 Microsoft에서 만든 라이브러리입니다. 복잡한 보안 토큰 관리, 로그인 처리, 세션 갱신 코드를 직접 작성할 필요 없이 MSAL이 이를 대신 처리합니다.

    MSAL 사용을 권장하는 이유는:

  • 안전성: 업계 표준 프로토콜과 보안 모범 사례를 구현해 코드 취약점 위험을 줄입니다.
  • 개발 간소화: OAuth 2.0과 OpenID Connect의 복잡함을 추상화해 몇 줄의 코드로 강력한 인증 기능을 추가할 수 있습니다.
  • 지속적 유지보수: Microsoft가 적극적으로 관리하며 새로운 보안 위협과 플랫폼 변화에 대응합니다.
  • MSAL은 .NET, JavaScript/TypeScript, Python, Java, Go, iOS, Android 등 다양한 언어와 프레임워크를 지원해 전체 기술 스택에서 일관된 인증 패턴을 사용할 수 있습니다.

    MSAL에 대해 더 알고 싶다면 공식 MSAL 개요 문서를 참고하세요.

    Entra ID로 MCP 서버 보호하기: 단계별 가이드

    이제 Entra ID를 사용해 로컬 MCP 서버(stdio 통신)를 보호하는 방법을 살펴보겠습니다. 이 예제는 사용자의 컴퓨터에서 실행되는 데스크톱 앱이나 로컬 개발 서버에 적합한 공개 클라이언트를 사용합니다.

    시나리오 1: 로컬 MCP 서버 보호 (공개 클라이언트)

    이 시나리오에서는 로컬에서 실행되고 stdio로 통신하는 MCP 서버가 Entra ID로 사용자를 인증한 후 도구 접근을 허용하는 과정을 다룹니다. 서버에는 Microsoft Graph API에서 사용자 프로필 정보를 가져오는 단일 도구가 있습니다.

    1. Entra ID에서 애플리케이션 설정하기

    코드를 작성하기 전에 Microsoft Entra ID에 애플리케이션을 등록해야 합니다. 이는 Entra ID에 애플리케이션 정보를 알려 인증 서비스를 사용할 권한을 부여하는 과정입니다.

    1. Microsoft Entra 포털에 접속합니다.

    2. 앱 등록(App registrations)으로 이동해 새 등록(New registration)을 클릭합니다.

    3. 애플리케이션 이름(예: "My Local MCP Server")을 입력합니다.

    4. 지원되는 계정 유형(Supported account types)에서 이 조직 디렉터리의 계정만(Accounts in this organizational directory only)을 선택합니다.

    5. 이 예제에서는 리디렉션 URI(Redirect URI)를 비워둡니다.

    6. 등록(Register)을 클릭합니다.

    등록 후 애플리케이션(클라이언트) ID디렉터리(테넌트) ID를 기록해 두세요. 코드에서 필요합니다.

    2. 코드 주요 부분 설명

    인증을 처리하는 핵심 코드를 살펴보겠습니다.

    전체 코드는 mcp-auth-servers GitHub 저장소Entra ID - Local - WAM 폴더에서 확인할 수 있습니다.

    AuthenticationService.cs

    이 클래스는 Entra ID와의 상호작용을 담당합니다.

  • CreateAsync: MSAL의 PublicClientApplication을 초기화합니다. 애플리케이션의 clientIdtenantId로 구성됩니다.
  • WithBroker: Windows Web Account Manager 같은 브로커 사용을 활성화해 더 안전하고 원활한 싱글 사인온 경험을 제공합니다.
  • AcquireTokenAsync: 핵심 메서드로, 먼저 조용히 토큰을 얻으려 시도합니다(이미 유효한 세션이 있으면 로그인 과정 없이 토큰 획득). 실패하면 사용자에게 로그인 창을 띄워 인증을 진행합니다.
  • 
    // Simplified for clarity
    
    public static async Task<AuthenticationService> CreateAsync(ILogger<AuthenticationService> logger)
    
    {
    
        var msalClient = PublicClientApplicationBuilder
    
            .Create(_clientId) // Your Application (client) ID
    
            .WithAuthority(AadAuthorityAudience.AzureAdMyOrg)
    
            .WithTenantId(_tenantId) // Your Directory (tenant) ID
    
            .WithBroker(new BrokerOptions(BrokerOptions.OperatingSystems.Windows))
    
            .Build();
    
    
    
        // ... cache registration ...
    
    
    
        return new AuthenticationService(logger, msalClient);
    
    }
    
    
    
    public async Task<string> AcquireTokenAsync()
    
    {
    
        try
    
        {
    
            // Try silent authentication first
    
            var accounts = await _msalClient.GetAccountsAsync();
    
            var account = accounts.FirstOrDefault();
    
    
    
            AuthenticationResult? result = null;
    
    
    
            if (account != null)
    
            {
    
                result = await _msalClient.AcquireTokenSilent(_scopes, account).ExecuteAsync();
    
            }
    
            else
    
            {
    
                // If no account, or silent fails, go interactive
    
                result = await _msalClient.AcquireTokenInteractive(_scopes).ExecuteAsync();
    
            }
    
    
    
            return result.AccessToken;
    
        }
    
        catch (Exception ex)
    
        {
    
            _logger.LogError(ex, "An error occurred while acquiring the token.");
    
            throw; // Optionally rethrow the exception for higher-level handling
    
        }
    
    }
    
    

    Program.cs

    MCP 서버를 설정하고 인증 서비스를 통합하는 부분입니다.

  • AddSingleton: AuthenticationService를 의존성 주입 컨테이너에 등록해 다른 부분(예: 도구)에서 사용할 수 있게 합니다.
  • GetUserDetailsFromGraph 도구: 이 도구는 AuthenticationService 인스턴스를 필요로 합니다. 실행 전에 authService.AcquireTokenAsync()를 호출해 유효한 액세스 토큰을 얻습니다. 인증에 성공하면 토큰을 사용해 Microsoft Graph API를 호출해 사용자 정보를 가져옵니다.
  • 
    // Simplified for clarity
    
    [McpServerTool(Name = "GetUserDetailsFromGraph")]
    
    public static async Task<string> GetUserDetailsFromGraph(
    
        AuthenticationService authService)
    
    {
    
        try
    
        {
    
            // This will trigger the authentication flow
    
            var accessToken = await authService.AcquireTokenAsync();
    
    
    
            // Use the token to create a GraphServiceClient
    
            var graphClient = new GraphServiceClient(
    
                new BaseBearerTokenAuthenticationProvider(new TokenProvider(authService)));
    
    
    
            var user = await graphClient.Me.GetAsync();
    
    
    
            return System.Text.Json.JsonSerializer.Serialize(user);
    
        }
    
        catch (Exception ex)
    
        {
    
            return $"Error: {ex.Message}";
    
        }
    
    }
    
    
    3. 전체 동작 과정

    1.

    MCP 클라이언트가 GetUserDetailsFromGraph 도구를 사용하려 할 때, 도구는 먼저 AcquireTokenAsync를 호출합니다.

    2. AcquireTokenAsync는 MSAL 라이브러리를 통해 유효한 토큰이 있는지 확인합니다.

    3. 토큰이 없으면 MSAL이 브로커를 통해 사용자에게 Entra ID 계정으로 로그인하라는 창을 띄웁니다.

    4. 사용자가 로그인하면 Entra ID가 액세스 토큰을 발급합니다.

    5. 도구는 토큰을 받아 Microsoft Graph API에 안전하게 요청을 보냅니다.

    6. 사용자 정보가 MCP 클라이언트에 반환됩니다.

    이 과정으로 인증된 사용자만 도구를 사용할 수 있어 로컬 MCP 서버가 안전하게 보호됩니다.

    시나리오 2: 원격 MCP 서버 보호 (기밀 클라이언트)

    MCP 서버가 원격 머신(예: 클라우드 서버)에서 실행되고 HTTP 스트리밍 같은 프로토콜로 통신할 때는 보안 요구사항이 다릅니다. 이 경우 기밀 클라이언트Authorization Code Flow를 사용해야 합니다. 이 방법은 애플리케이션 비밀이 브라우저에 노출되지 않아 더 안전합니다.

    이 예제는 Express.js를 사용해 HTTP 요청을 처리하는 TypeScript 기반 MCP 서버를 다룹니다.

    1. Entra ID에서 애플리케이션 설정하기

    설정은 공개 클라이언트와 비슷하지만, 클라이언트 비밀(client secret)을 생성해야 한다는 점이 다릅니다.

    1. Microsoft Entra 포털에 접속합니다.

    2. 앱 등록에서 인증서 및 비밀(Certificates & secrets) 탭으로 이동합니다.

    3. 새 클라이언트 비밀(New client secret)을 클릭하고 설명을 입력한 후 추가(Add)를 클릭합니다.

    4. 중요: 생성된 비밀 값을 즉시 복사하세요. 다시 볼 수 없습니다.

    5. 리디렉션 URI도 설정해야 합니다. 인증(Authentication) 탭에서 플랫폼 추가(Add a platform)를 클릭하고 웹(Web)을 선택한 뒤 애플리케이션의 리디렉션 URI(예: http://localhost:3001/auth/callback)를 입력합니다.

    > ⚠️ 중요한 보안 참고: 운영 환경에서는 클라이언트 비밀 대신 Managed IdentityWorkload Identity Federation 같은 비밀 없는 인증 방식을 사용하는 것을 Microsoft가 강력히 권장합니다.

    클라이언트 비밀은 노출되거나 탈취될 위험이 있습니다.

    관리형 아이덴티티는 코드나 설정에 자격 증명을 저장할 필요가 없어 더 안전합니다.

    >

    > 관리형 아이덴티티에 대한 자세한 내용과 구현 방법은 Azure 리소스용 관리형 아이덴티티 개요를 참고하세요.

    2. 코드 주요 부분 설명

    이 예제는 세션 기반 방식을 사용합니다.

    사용자가 인증하면 서버가 액세스 토큰과 갱신 토큰을 세션에 저장하고, 사용자에게 세션 토큰을 제공합니다.

    이후 요청에 이 세션 토큰을 사용합니다.

    전체 코드는 mcp-auth-servers GitHub 저장소Entra ID - Confidential client 폴더에서 확인할 수 있습니다.

    Server.ts

    Express 서버와 MCP 전송 계층을 설정합니다.

  • requireBearerAuth: /sse/message 엔드포인트를 보호하는 미들웨어입니다. 요청의 Authorization 헤더에 유효한 베어러 토큰이 있는지 확인합니다.
  • EntraIdServerAuthProvider: McpServerAuthorizationProvider 인터페이스를 구현한 커스텀 클래스입니다. OAuth 2.0 흐름을 처리합니다.
  • /auth/callback: 사용자가 인증 후 Entra ID에서 리디렉션될 때 호출되는 엔드포인트입니다. 권한 코드를 액세스 토큰과 갱신 토큰으로 교환합니다.
  • 
    // Simplified for clarity
    
    const app = express();
    
    const { server } = createServer();
    
    const provider = new EntraIdServerAuthProvider();
    
    
    
    // Protect the SSE endpoint
    
    app.get("/sse", requireBearerAuth({
    
      provider,
    
      requiredScopes: ["User.Read"]
    
    }), async (req, res) => {
    
      // ... connect to the transport ...
    
    });
    
    
    
    // Protect the message endpoint
    
    app.post("/message", requireBearerAuth({
    
      provider,
    
      requiredScopes: ["User.Read"]
    
    }), async (req, res) => {
    
      // ... handle the message ...
    
    });
    
    
    
    // Handle the OAuth 2.0 callback
    
    app.get("/auth/callback", (req, res) => {
    
      provider.handleCallback(req.query.code, req.query.state)
    
        .then(result => {
    
          // ... handle success or failure ...
    
        });
    
    });
    
    

    Tools.ts

    MCP 서버가 제공하는 도구들을 정의합니다. getUserDetails 도구는 이전 예제와 비슷하지만, 액세스 토큰을 세션에서 가져옵니다.

    
    // Simplified for clarity
    
    server.setRequestHandler(CallToolRequestSchema, async (request) => {
    
      const { name } = request.params;
    
      const context = request.params?.context as { token?: string } | undefined;
    
      const sessionToken = context?.token;
    
    
    
      if (name === ToolName.GET_USER_DETAILS) {
    
        if (!sessionToken) {
    
          throw new AuthenticationError("Authentication token is missing or invalid. Ensure the token is provided in the request context.");
    
        }
    
    
    
        // Get the Entra ID token from the session store
    
        const tokenData = tokenStore.getToken(sessionToken);
    
        const entraIdToken = tokenData.accessToken;
    
    
    
        const graphClient = Client.init({
    
          authProvider: (done) => {
    
            done(null, entraIdToken);
    
          }
    
        });
    
    
    
        const user = await graphClient.api('/me').get();
    
    
    
        // ... return user details ...
    
      }
    
    });
    
    

    auth/EntraIdServerAuthProvider.ts

    이 클래스는 다음 로직을 처리합니다:

  • 사용자를 Entra ID 로그인 페이지로 리디렉션
  • 권한 코드를 액세스 토큰으로 교환
  • 토큰을 tokenStore에 저장
  • 액세스 토큰 만료 시 갱신
  • 3. 전체 동작 과정

    1. 사용자가 처음 MCP 서버에 연결하려 하면, requireBearerAuth 미들웨어가 유효한 세션이 없음을 감지하고 Entra ID 로그인 페이지로 리디렉션합니다.

    2. 사용자가 Entra ID 계정으로 로그인합니다.

    3. Entra ID가 권한 코드를 포함해 사용자를 /auth/callback 엔드포인트로 리디렉션합니다.

    4. 서버는 코드를 액세스 토큰과 리프레시 토큰으로 교환하여 저장하고, 세션 토큰을 생성하여 클라이언트에 전송합니다.

    5. 클라이언트는 이제 이 세션 토큰을 Authorization 헤더에 포함시켜 MCP 서버에 대한 모든 향후 요청에 사용할 수 있습니다.

    6. getUserDetails 도구가 호출되면 세션 토큰을 사용해 Entra ID 액세스 토큰을 조회하고, 이를 이용해 Microsoft Graph API를 호출합니다.

    이 흐름은 공개 클라이언트 흐름보다 복잡하지만, 인터넷에 노출된 엔드포인트에는 필수적입니다. 원격 MCP 서버는 공용 인터넷을 통해 접근 가능하므로, 무단 접근과 잠재적 공격으로부터 보호하기 위해 더 강력한 보안 조치가 필요합니다.

    보안 모범 사례

  • 항상 HTTPS 사용: 클라이언트와 서버 간 통신을 암호화하여 토큰이 가로채이지 않도록 보호하세요.
  • 역할 기반 접근 제어(RBAC) 구현: 사용자가 인증되었는지 여부뿐만 아니라, 어떤 권한이 있는지도 확인하세요. Entra ID에서 역할을 정의하고 MCP 서버에서 이를 검증할 수 있습니다.
  • 모니터링 및 감사: 모든 인증 이벤트를 기록하여 의심스러운 활동을 탐지하고 대응할 수 있도록 하세요.
  • 요청 제한 및 스로틀링 처리: Microsoft Graph 및 기타 API는 남용을 방지하기 위해 요청 제한을 적용합니다. MCP 서버에서 지수 백오프 및 재시도 로직을 구현하여 HTTP 429(요청 과다) 응답을 우아하게 처리하세요. 자주 조회하는 데이터를 캐싱하여 API 호출을 줄이는 것도 고려하세요.
  • 토큰 안전 저장: 액세스 토큰과 리프레시 토큰을 안전하게 저장하세요. 로컬 애플리케이션의 경우 시스템의 보안 저장소를 사용하고, 서버 애플리케이션은 암호화 저장소나 Azure Key Vault 같은 보안 키 관리 서비스를 활용하세요.
  • 토큰 만료 처리: 액세스 토큰은 유효 기간이 제한되어 있습니다. 리프레시 토큰을 사용해 자동으로 토큰을 갱신하여 재인증 없이 원활한 사용자 경험을 유지하세요.
  • Azure API Management 사용 고려: MCP 서버에 직접 보안을 구현하면 세밀한 제어가 가능하지만, Azure API Management 같은 API 게이트웨이는 인증, 권한 부여, 요청 제한, 모니터링 등 많은 보안 문제를 자동으로 처리해 줍니다. 클라이언트와 MCP 서버 사이에 중앙 집중식 보안 계층을 제공합니다. MCP와 API 게이트웨이 사용에 대한 자세한 내용은 Azure API Management Your Auth Gateway For MCP Servers를 참고하세요.

    컨텍스트 엔지니어링: MCP 생태계에서 떠오르는 개념

    개요

    컨텍스트 엔지니어링은 AI 분야에서 새롭게 떠오르는 개념으로, 클라이언트와 AI 서비스 간의 상호작용에서 정보가 어떻게 구조화되고 전달되며 유지되는지를 탐구합니다. 모델 컨텍스트 프로토콜(MCP) 생태계가 발전함에 따라, 컨텍스트를 효과적으로 관리하는 방법을 이해하는 것이 점점 더 중요해지고 있습니다. 이 모듈은 컨텍스트 엔지니어링의 개념을 소개하고 MCP 구현에서의 잠재적 응용을 탐구합니다.

    학습 목표

    이 모듈을 완료하면 다음을 수행할 수 있습니다:

  • 컨텍스트 엔지니어링의 개념과 MCP 응용에서의 잠재적 역할을 이해하기
  • MCP 프로토콜 설계가 해결하는 컨텍스트 관리의 주요 과제를 식별하기
  • 더 나은 컨텍스트 처리를 통해 모델 성능을 향상시키는 기술 탐구하기
  • 컨텍스트 효과성을 측정하고 평가하는 접근법 고려하기
  • MCP 프레임워크를 통해 AI 경험을 개선하기 위해 이러한 새로운 개념 적용하기
  • 컨텍스트 엔지니어링 소개

    컨텍스트 엔지니어링은 사용자, 애플리케이션, AI 모델 간의 정보 흐름을 의도적으로 설계하고 관리하는 데 초점을 맞춘 새로운 개념입니다. 프롬프트 엔지니어링과 같은 기존 분야와 달리, 컨텍스트 엔지니어링은 AI 모델에 적시에 적절한 정보를 제공하는 독특한 과제를 해결하려는 실무자들에 의해 아직 정의되고 있는 단계입니다.

    대규모 언어 모델(LLM)이 발전함에 따라 컨텍스트의 중요성이 점점 더 명확해지고 있습니다. 우리가 제공하는 컨텍스트의 품질, 관련성, 구조는 모델 출력에 직접적인 영향을 미칩니다. 컨텍스트 엔지니어링은 이 관계를 탐구하고 효과적인 컨텍스트 관리를 위한 원칙을 개발하려고 합니다.

    > "2025년에는 모델들이 매우 지능적입니다. 하지만 가장 똑똑한 사람이라도 자신이 해야 할 일을 이해하는 컨텍스트 없이는 효과적으로 일을 수행할 수 없습니다... '컨텍스트 엔지니어링'은 프롬프트 엔지니어링의 다음 단계입니다. 이는 동적 시스템에서 이를 자동으로 수행하는 것입니다." — Walden Yan, Cognition AI

    컨텍스트 엔지니어링은 다음을 포함할 수 있습니다:

    1. 컨텍스트 선택: 특정 작업에 적합한 정보를 결정하기

    2. 컨텍스트 구조화: 모델 이해를 극대화하기 위해 정보를 조직화하기

    3. 컨텍스트 전달: 정보가 모델에 전달되는 방식과 시점을 최적화하기

    4. 컨텍스트 유지: 시간에 따라 컨텍스트의 상태와 진화를 관리하기

    5. 컨텍스트 평가: 컨텍스트의 효과성을 측정하고 개선하기

    이러한 초점 영역은 특히 LLM에 컨텍스트를 제공하는 표준화된 방법을 제공하는 MCP 생태계와 관련이 있습니다.

    컨텍스트 여정 관점

    컨텍스트 엔지니어링을 시각화하는 한 가지 방법은 MCP 시스템을 통해 정보가 이동하는 여정을 추적하는 것입니다:

    컨텍스트 여정의 주요 단계:

    1. 사용자 입력: 사용자로부터의 원시 정보(텍스트, 이미지, 문서)

    2. 컨텍스트 조립: 사용자 입력을 시스템 컨텍스트, 대화 기록 및 기타 검색된 정보와 결합하기

    3. 모델 처리: AI 모델이 조립된 컨텍스트를 처리하기

    4. 응답 생성: 모델이 제공된 컨텍스트를 기반으로 출력 생성하기

    5. 상태 관리: 시스템이 상호작용을 기반으로 내부 상태를 업데이트하기

    이 관점은 AI 시스템에서 컨텍스트의 역동적인 특성을 강조하며 각 단계에서 정보를 최적으로 관리하는 방법에 대한 중요한 질문을 제기합니다.

    컨텍스트 엔지니어링의 떠오르는 원칙

    컨텍스트 엔지니어링 분야가 형성됨에 따라 실무자들로부터 몇 가지 초기 원칙이 나타나고 있습니다. 이러한 원칙은 MCP 구현 선택에 정보를 제공하는 데 도움이 될 수 있습니다.

    원칙 1: 컨텍스트를 완전히 공유하기

    컨텍스트는 시스템의 모든 구성 요소 간에 완전히 공유되어야 하며, 여러 에이전트나 프로세스에 분산되지 않아야 합니다. 컨텍스트가 분산되면 시스템의 한 부분에서 내린 결정이 다른 곳에서 내린 결정과 충돌할 수 있습니다.

    MCP 응용에서는 컨텍스트가 여러 부분으로 나뉘는 대신 전체 파이프라인을 통해 원활하게 흐르도록 설계하는 것이 좋습니다.

    원칙 2: 행동이 암묵적 결정을 포함한다는 점을 인식하기

    모델이 취하는 각 행동은 컨텍스트를 해석하는 방법에 대한 암묵적 결정을 포함합니다. 여러 구성 요소가 서로 다른 컨텍스트에서 작동하면 이러한 암묵적 결정이 충돌하여 일관되지 않은 결과를 초래할 수 있습니다.

    이 원칙은 MCP 응용에 중요한 영향을 미칩니다:

  • 복잡한 작업의 병렬 실행 대신 선형 처리를 선호하기
  • 모든 의사 결정 지점이 동일한 컨텍스트 정보를 사용할 수 있도록 보장하기
  • 후속 단계가 이전 결정의 전체 컨텍스트를 볼 수 있도록 시스템 설계하기
  • 원칙 3: 컨텍스트 깊이와 윈도우 제한 간의 균형 유지하기

    대화와 프로세스가 길어질수록 컨텍스트 윈도우가 결국 넘쳐납니다. 효과적인 컨텍스트 엔지니어링은 포괄적인 컨텍스트와 기술적 제한 간의 긴장을 관리하는 접근법을 탐구합니다.

    탐구 중인 잠재적 접근법은 다음을 포함합니다:

  • 토큰 사용을 줄이면서 필수 정보를 유지하는 컨텍스트 압축
  • 현재 필요에 따라 관련성을 기준으로 컨텍스트를 점진적으로 로드하기
  • 이전 상호작용을 요약하면서 주요 결정과 사실을 보존하기
  • 컨텍스트 과제와 MCP 프로토콜 설계

    모델 컨텍스트 프로토콜(MCP)은 컨텍스트 관리의 독특한 과제를 인식하여 설계되었습니다. 이러한 과제를 이해하면 MCP 프로토콜 설계의 주요 측면을 설명하는 데 도움이 됩니다:

    과제 1: 컨텍스트 윈도우 제한

    대부분의 AI 모델은 고정된 컨텍스트 윈도우 크기를 가지며, 한 번에 처리할 수 있는 정보의 양이 제한됩니다.

    MCP 설계 응답:

  • 프로토콜은 효율적으로 참조할 수 있는 구조화된 리소스 기반 컨텍스트를 지원합니다.
  • 리소스는 페이지로 나뉘어 점진적으로 로드될 수 있습니다.
  • 과제 2: 관련성 결정

    컨텍스트에 포함할 정보 중 가장 관련성이 높은 것을 결정하는 것은 어렵습니다.

    MCP 설계 응답:

  • 필요에 따라 정보를 동적으로 검색할 수 있는 유연한 도구 제공
  • 일관된 컨텍스트 조직을 가능하게 하는 구조화된 프롬프트 제공
  • 과제 3: 컨텍스트 지속성

    상호작용 간 상태를 관리하려면 컨텍스트를 신중하게 추적해야 합니다.

    MCP 설계 응답:

  • 표준화된 세션 관리
  • 컨텍스트 진화를 위한 명확히 정의된 상호작용 패턴
  • 과제 4: 멀티모달 컨텍스트

    텍스트, 이미지, 구조화된 데이터와 같은 다양한 유형의 데이터는 서로 다른 처리가 필요합니다.

    MCP 설계 응답:

  • 다양한 콘텐츠 유형을 수용하는 프로토콜 설계
  • 멀티모달 정보를 표준화된 방식으로 표현
  • 과제 5: 보안 및 개인정보 보호

    컨텍스트는 종종 보호해야 할 민감한 정보를 포함합니다.

    MCP 설계 응답:

  • 클라이언트와 서버 간 책임의 명확한 경계 설정
  • 데이터 노출을 최소화하기 위한 로컬 처리 옵션 제공
  • 이러한 과제를 이해하고 MCP가 이를 해결하는 방법을 알면 더 발전된 컨텍스트 엔지니어링 기술을 탐구할 수 있는 기반을 제공합니다.

    떠오르는 컨텍스트 엔지니어링 접근법

    컨텍스트 엔지니어링 분야가 발전함에 따라 몇 가지 유망한 접근법이 나타나고 있습니다. 이는 현재의 사고를 반영하며, 확립된 모범 사례가 아니라 MCP 구현 경험이 축적됨에 따라 진화할 가능성이 있습니다.

    1. 단일 스레드 선형 처리

    컨텍스트를 분산하는 멀티 에이전트 아키텍처와는 달리, 일부 실무자들은 단일 스레드 선형 처리가 더 일관된 결과를 생성한다고 보고 있습니다. 이는 통합된 컨텍스트를 유지하는 원칙과 일치합니다.

        B --> C[Process Step 2]
    
        C --> D[Process Step 3]
    
        D --> E[Result]
    
        
    
        style A fill:#A9CCE3,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style B fill:#A3E4D7,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style C fill:#F9E79F,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style D fill:#F5CBA7,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style E fill:#D2B4DE,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
    

    이 접근법은 병렬 처리보다 덜 효율적으로 보일 수 있지만, 각 단계가 이전 결정의 완전한 이해를 기반으로 구축되기 때문에 더 일관되고 신뢰할 수 있는 결과를 생성하는 경우가 많습니다.

    2. 컨텍스트 청킹 및 우선순위 설정

    큰 컨텍스트를 관리 가능한 조각으로 나누고 가장 중요한 부분에 우선순위를 부여하기.

    
    # Conceptual Example: Context Chunking and Prioritization
    
    def process_with_chunked_context(documents, query):
    
        # 1. Break documents into smaller chunks
    
        chunks = chunk_documents(documents)
    
        
    
        # 2. Calculate relevance scores for each chunk
    
        scored_chunks = [(chunk, calculate_relevance(chunk, query)) for chunk in chunks]
    
        
    
        # 3. Sort chunks by relevance score
    
        sorted_chunks = sorted(scored_chunks, key=lambda x: x[1], reverse=True)
    
        
    
        # 4. Use the most relevant chunks as context
    
        context = create_context_from_chunks([chunk for chunk, score in sorted_chunks[:5]])
    
        
    
        # 5. Process with the prioritized context
    
        return generate_response(context, query)
    
    

    위 개념은 큰 문서를 관리 가능한 조각으로 나누고 컨텍스트에 가장 관련성이 높은 부분만 선택하는 방법을 보여줍니다. 이 접근법은 컨텍스트 윈도우 제한 내에서 작업하면서도 대규모 지식 기반을 활용하는 데 도움이 될 수 있습니다.

    3. 점진적 컨텍스트 로딩

    컨텍스트를 한 번에 모두 로드하지 않고 필요에 따라 점진적으로 로드하기.

        end
    
        
    
        MCP Server->>App: Response
    
        App->>User: Answer
    
    

    점진적 컨텍스트 로딩은 최소한의 컨텍스트로 시작하여 필요할 때만 확장합니다. 이는 간단한 쿼리에 대해 토큰 사용을 크게 줄이면서 복잡한 질문을 처리할 수 있는 능력을 유지할 수 있습니다.

    4. 컨텍스트 압축 및 요약

    필수 정보를 보존하면서 컨텍스트 크기를 줄이기.

    
    graph TD
    
        A[Full Context] --> B[Compression Model]
    
        B --> C[Compressed Context]
    
        C --> D[Main Processing Model]
    
        D --> E[Response]
    
        
    
        style A fill:#A9CCE3,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style B fill:#A3E4D7,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style C fill:#F5CBA7,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style D fill:#D2B4DE,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
        style E fill:#F9E79F,stroke:#000000,stroke-width:2px,color:#000000,font-weight:bold
    
    

    컨텍스트 압축은 다음에 초점을 맞춥니다:

  • 중복 정보 제거
  • 긴 콘텐츠 요약
  • 주요 사실과 세부 사항 추출
  • 중요한 컨텍스트 요소 보존
  • 토큰 효율성을 최적화
  • 이 접근법은 긴 대화를 컨텍스트 윈도우 내에서 유지하거나 대규모 문서를 효율적으로 처리하는 데 특히 유용할 수 있습니다. 일부 실무자들은 대화 기록의 컨텍스트 압축 및 요약을 위해 전문화된 모델을 사용하고 있습니다.

    탐구적 컨텍스트 엔지니어링 고려사항

    MCP 구현에서 컨텍스트 엔지니어링의 새로운 분야를 탐구할 때, 특정 사용 사례에서 개선을 가져올 수 있는 몇 가지 고려사항을 염두에 두는 것이 좋습니다. 이는 규범적인 모범 사례가 아니라 탐구 영역으로, 개선 가능성을 제시합니다.

    컨텍스트 목표를 고려하기

    복잡한 컨텍스트 관리 솔루션을 구현하기 전에 달성하려는 목표를 명확히 표현하십시오:

  • 모델이 성공하기 위해 필요한 특정 정보는 무엇인가?
  • 필수 정보와 보조 정보는 무엇인가?
  • 성능 제약(지연 시간, 토큰 제한, 비용)은 무엇인가?
  • 계층화된 컨텍스트 접근법 탐구하기

    일부 실무자들은 개념적 계층으로 배열된 컨텍스트에서 성공을 찾고 있습니다:

  • 핵심 계층: 모델이 항상 필요로 하는 필수 정보
  • 상황 계층: 현재 상호작용에 특정한 컨텍스트
  • 지원 계층: 도움이 될 수 있는 추가 정보
  • 백업 계층: 필요할 때만 접근하는 정보
  • 검색 전략 조사하기

    컨텍스트의 효과는 정보를 검색하는 방법에 따라 달라질 수 있습니다:

  • 개념적으로 관련성이 높은 정보를 찾기 위한 의미적 검색 및 임베딩
  • 특정 사실적 세부 정보를 위한 키워드 기반 검색
  • 여러 검색 방법을 결합한 하이브리드 접근법
  • 범주, 날짜 또는 출처를 기준으로 범위를 좁히기 위한 메타데이터 필터링
  • 컨텍스트 일관성 실험하기

    컨텍스트의 구조와 흐름은 모델 이해에 영향을 미칠 수 있습니다:

  • 관련 정보를 함께 그룹화하기
  • 일관된 형식과 조직 사용하기
  • 적절한 경우 논리적 또는 연대기적 순서를 유지하기
  • 모순된 정보 피하기
  • 멀티 에이전트 아키텍처의 트레이드오프 평가하기

    멀티 에이전트 아키텍처는 많은 AI 프레임워크에서 인기가 있지만, 컨텍스트 관리에 상당한 과제를 수반합니다:

  • 컨텍스트 분산은 에이전트 간의 결정 불일치를 초래할 수 있습니다.
  • 병렬 처리는 조정하기 어려운 충돌을 초래할 수 있습니다.
  • 에이전트 간의 통신 오버헤드는 성능 이점을 상쇄할 수 있습니다.
  • 일관성을 유지하기 위해 복잡한 상태 관리가 필요합니다.
  • 많은 경우, 단일 에이전트 접근법과 포괄적인 컨텍스트 관리가 분산된 컨텍스트를 가진 여러 전문 에이전트보다 더 신뢰할 수 있는 결과를 생성할 수 있습니다.

    평가 방법 개발하기

    시간이 지남에 따라 컨텍스트 엔지니어링을 개선하려면 성공을 측정할 방법을 고려하십시오:

  • 다양한 컨텍스트 구조를 A/B 테스트하기
  • 토큰 사용 및 응답 시간 모니터링하기
  • 사용자 만족도 및 작업 완료율 추적하기
  • 컨텍스트 전략이 실패하는 시점과 이유 분석하기
  • 이러한 고려사항은 컨텍스트 엔지니어링 공간에서의 적극적인 탐구 영역을 나타냅니다. 분야가 성숙해지면 더 명확한 패턴과 관행이 나타날 가능성이 높습니다.

    컨텍스트 효과성 측정: 진화하는 프레임워크

    컨텍스트 엔지니어링이 개념으로 떠오르면서 실무자들은 효과성을 측정할 방법을 탐구하기 시작했습니다. 아직 확립된 프레임워크는 없지만, 미래 작업을 안내할 수 있는 다양한 지표가 고려되고 있습니다.

    잠재적 측정 차원

    1. 입력 효율성 고려사항
  • 컨텍스트 대 응답 비율: 응답 크기에 비해 얼마나 많은 컨텍스트가 필요한가?
  • 토큰 활용도: 제공된 컨텍스트 토큰 중 응답에 영향을 미치는 비율은 얼마인가?
  • 컨텍스트 축소: 원시 정보를 얼마나 효과적으로 압축할 수 있는가?
  • 2. 성능 고려사항
  • 지연 시간 영향: 컨텍스트 관리가 응답 시간에 어떤 영향을 미치는가?
  • 토큰 경제성: 토큰 사용을 효과적으로 최적화하고 있는가?
  • 검색 정확도: 검색된 정보의 관련성은 얼마나 높은가?
  • 자원 활용도: 필요한 계산 자원은 무엇인가?
  • 3. 품질 고려사항
  • 응답 관련성: 응답이 쿼리를 얼마나 잘 해결하는가?
  • 사실적 정확성: 컨텍스트 관리가 사실적 정확성을 개선하는가?
  • 일관성: 유사한 쿼리에서 응답이 일관적인가?
  • 환각률: 더 나은 컨텍스트가 모델 환각을 줄이는가?
  • 4. 사용자 경험 고려사항
  • 후속 요청 비율: 사용자가 얼마나 자주 명확성을 요구하는가?
  • 작업 완료율: 사용자가 목표를 성공적으로 달성하는가?
  • 만족도 지표: 사용자가 경험을 어떻게 평가하는가?
  • 측정에 대한 탐구적 접근법

    MCP 구현에서 컨텍스트 엔지니어링을 실험할 때, 다음 탐구적 접근법을 고려하십시오:

    1. 기준 비교: 간단한 컨텍스트 접근법으로 기준을 설정한 후 더 정교한 방법을 테스트하기

    2. 점진적 변화: 컨텍스트 관리의 한 측면만 변경하여 그 효과를 분리하기

    3. 사용자 중심 평가: 정량적 지표와 사용자 피드백을 결합하기

    4. 실패 분석: 컨텍스트 전략이 실패하는 사례를 조사하여 잠재적 개선 사항 이해하기

    5. 다차원 평가: 효율성, 품질, 사용자 경험 간의 트레이드오프 고려하기

    이 실험적이고 다각적인 측정 접근법은 컨텍스트 엔지니어링의 떠오르는 특성과 일치합니다.

    마무리 생각

    컨텍스트 엔지니어링은 MCP 응용을 효과적으로 구현하는 데 중심이 될 수 있는 새로운 탐구 영역입니다. 시스템을 통해 정보가 흐르는 방식을 신중히 고려함으로써 더 효율적이고 정확하며 사용자에게 가치 있는 AI 경험을 창출할 수 있습니다.

    이 모듈에서 설명한 기술과 접근법은 이 공간에서 초기 사고를 나타내며, 확립된 관행이 아닙니다. 컨텍스트 엔지니어링은 AI 능력이 발전하고 우리의 이해가 깊어짐에 따라 더 정의된 학문으로 발전할 수 있습니다. 현재로서는 신중한 측정과 실험이 가장 생산적인 접근법으로 보입니다.

    엔터프라이즈 통합 시나리오

    시나리오 1: 분산 MCP 처리

    Azure Event Grid를 사용하여 여러 처리 노드에 MCP 요청 분산:

    
    Architecture:
    
      - MCP Client sends requests to Event Grid topic
    
      - Multiple Azure Functions subscribe to process different tool types
    
      - Results aggregated and returned via separate response topic
    
      
    
    Benefits:
    
      - Horizontal scaling based on message volume
    
      - Fault tolerance through redundant processors
    
      - Cost optimization with serverless compute
    
    

    시나리오 2: 실시간 MCP 스트리밍

    Azure Event Hubs를 사용한 고빈도 MCP 상호작용:

    
    Architecture:
    
      - MCP Client streams continuous requests via Event Hubs
    
      - Stream Analytics processes and routes messages
    
      - Multiple consumers handle different aspect of processing
    
      
    
    Benefits:
    
      - Low latency for real-time scenarios
    
      - High throughput for batch processing
    
      - Built-in partitioning for parallel processing
    
    

    시나리오 3: 하이브리드 전송 아키텍처

    다양한 사용 사례를 위한 여러 전송 결합:

    
    public class HybridMcpTransport : IMcpTransport
    
    {
    
        private readonly IMcpTransport _realtimeTransport; // Event Hubs
    
        private readonly IMcpTransport _batchTransport;    // Event Grid
    
        private readonly IMcpTransport _fallbackTransport; // HTTP Streaming
    
        
    
        public async Task SendMessageAsync(McpMessage message)
    
        {
    
            // Route based on message characteristics
    
            var transport = message.Method switch
    
            {
    
                "tools/call" when IsRealtime(message) => _realtimeTransport,
    
                "resources/read" when IsBatch(message) => _batchTransport,
    
                _ => _fallbackTransport
    
            };

    MCP를 이용한 적대적 다중 에이전트 추론

    다중 에이전트 토론 패턴은 서로 반대 입장을 가진 두 명 이상의 에이전트를 사용하여 단일 에이전트가 단독으로 달성할 수 있는 것보다 더 신뢰할 수 있고 잘 보정된 출력을 생성합니다.

    소개

    이 강의에서는 적대적 다중 에이전트 패턴을 살펴봅니다 — 이는 두 AI 에이전트가 특정 주제에 대해 상반된 입장을 할당받아 추론하고 MCP 도구를 호출하며 서로의 결론에 도전하는 기법입니다. 세 번째 에이전트(또는 인간 리뷰어)가 그 논거를 평가하여 최선의 결과를 결정합니다.

    이 패턴은 특히 다음에 유용합니다:

  • 환각 감지: 두 번째 에이전트가 첫 번째 에이전트가 제시한 근거 없는 주장에 도전합니다.
  • 위협 모델링 및 보안 리뷰: 한 에이전트는 시스템이 안전하다고 주장하고, 다른 에이전트는 취약점을 찾습니다.
  • API 또는 요구사항 설계: 한 에이전트는 제안된 설계를 방어하고, 다른 에이전트는 반론을 제기합니다.
  • 사실 검증: 두 에이전트 모두 독립적으로 동일한 MCP 도구를 조회하고 서로의 결론을 상호 검증합니다.
  • 동일한 MCP 도구 집합을 공유함으로써 두 에이전트는 동일한 정보 환경에서 작동합니다 — 이는 어떠한 의견 차이도 정보 비대칭이 아닌 진정한 추론 차이를 반영함을 의미합니다.

    학습 목표

    이 강의가 끝나면 다음을 할 수 있습니다:

  • 적대적 다중 에이전트 패턴이 단일 에이전트 파이프라인이 놓치는 오류를 포착하는 이유 설명하기
  • 두 에이전트가 공통 MCP 도구 집합을 공유하는 토론 아키텍처 설계하기
  • 각 에이전트가 할당된 입장을 주장하도록 안내하는 "찬성" 및 "반대" 시스템 프롬프트 구현하기
  • 토론을 최종 평결로 종합하는 판사 에이전트(또는 인간 리뷰 단계) 추가하기
  • 동시 에이전트 간 MCP 도구 공유 작동 방식 이해하기
  • 아키텍처 개요

    적대적 패턴은 다음과 같은 상위 흐름을 따릅니다:

    4단계 — 에이전트에 MCP 도구 연동

    위 Python 주관자 코드는 이미 완전한 MCP 연동 구현을 보여줍니다. 주요 패턴은 다음과 같습니다:

  • 하나의 공유 세션: run_debate가 단일 ClientSession을 열고 이를 각 run_agent_turn 호출에 전달하여 두 에이전트와 판사가 동일한 도구 환경에서 작동하게 함
  • 턴별 도구 목록 호출: run_agent_turnsession.list_tools()를 호출해 현재 도구 정의를 가져와 LLM에 tools 매개변수로 전달
  • 도구 사용 루프: 모델이 tool_use 블록을 반환하면 run_agent_turn이 각 도구에 대해 session.call_tool() 호출 후 결과를 모델에 다시 공급, 최종 텍스트 응답이 나올 때까지 반복
  • 각 언어별 전체 MCP 클라이언트 예제는 03-GettingStarted/02-client를 참고하세요.

    보안 고려사항

    운영 환경에서 적대적 에이전트를 실행할 때 다음을 유의하세요:

  • 샌드박스 코드 실행: run_python 도구는 격리된 환경(예: 네트워크 비접속 및 자원 제한이 있는 컨테이너)에서 실행되어야 합니다. 신뢰할 수 없는 LLM 생성 코드를 호스트에서 직접 실행하지 마세요.
  • 도구 호출 검증: 실행 전에 모든 도구 입력을 검증하세요. 두 에이전트가 동일한 도구 서버를 공유하므로 토론 중 악의적 프롬프트가 도구를 악용할 수 있습니다.
  • 속도 제한: 제어 불가능한 호출 루프를 막기 위해 에이전트별 도구 호출 횟수 제한을 적용하세요.
  • 감사 로깅: 각 도구 호출 및 결과를 로그에 남겨 각 에이전트가 어떤 증거로 결론에 도달했는지 추적 가능하도록 하세요.
  • 인간 참여: 중요한 결정의 경우, 판사의 평결을 인간 리뷰어에게 경유시킨 뒤 실행하세요.
  • MCP 보안 모범 사례에 관한 전체 안내는 02-Security를 참고하세요.

    연습 문제

    다음 시나리오 중 하나에 대해 적대적 MCP 파이프라인을 설계하세요:

    1. 코드 리뷰: 에이전트 A는 풀 리퀘스트를 방어하고, 에이전트 B는 버그, 보안 문제, 스타일 문제를 찾습니다. 판사는 주요 문제를 요약합니다.

    2. 아키텍처 결정: 에이전트 A는 마이크로서비스를 제안하고, 에이전트 B는 모놀리스를 옹호합니다. 판사는 결정 매트릭스를 작성합니다.

    3. 콘텐츠 검열: 에이전트 A는 게시할 콘텐츠가 안전하다고 주장하고, 에이전트 B는 정책 위반을 찾습니다. 판사는 위험 점수를 부여합니다.

    각 시나리오에 대해:

  • 두 에이전트와 판사의 시스템 프롬프트를 정의하세요.
  • 각 에이전트가 필요로 하는 MCP 도구를 식별하세요.
  • 메시지 흐름(초기 주장 → 반박 → 재반박 → 평결)을 구상하세요.
  • 평결을 실행하기 전에 어떻게 검증할지 설명하세요.
  • ---

    핵심 요약

  • 적대적 다중 에이전트 패턴은 상반된 시스템 프롬프트를 사용해 에이전트들이 서로의 추론을 철저히 검증하도록 만듭니다.
  • 하나의 MCP 도구 서버를 공유해 두 에이전트가 동일 정보를 기반으로 작업하므로 의견 차이는 데이터 접근이 아닌 추론 차이에 관한 것입니다.
  • 판사 에이전트가 토론을 실행 가능한 평결로 종합해 모든 결정마다 인간 병목 현상이 발생하지 않도록 합니다.
  • 이 패턴은 특히 환각 감지, 위협 모델링, 사실 검증, 설계 검토에 강력합니다.
  • 운영 환경에서 적대적 에이전트를 실행하려면 도구 실행 보안과 견고한 로깅이 필수입니다.
