🐙 Module 4: Practical MCP Development - Custom GitHub Clone Server

> ⚡ Quick Start: Build a production-ready MCP server that automates GitHub repository cloning and VS Code integration in just 30 minutes!

🎯 Learning Objectives

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

📋 Prerequisites

🏗️ Project Overview

Real-World Development Challenge

As developers, we frequently use GitHub to clone repositories and open them in VS Code or VS Code Insiders. This manual process involves:

1. Opening terminal/command prompt

2. Navigating to the desired directory

3. Running git clone command

4. Opening VS Code in the cloned directory

Our MCP solution streamlines this into a single intelligent command!

What You'll Build

A GitHub Clone MCP Server (git_mcp_server) that provides:

| Feature | Description | Benefit |

|---------|-------------|---------|

| 🔄 Smart Repository Cloning | Clone GitHub repos with validation | Automated error checking |

| 📁 Intelligent Directory Management | Check and create directories safely | Prevents overwriting |

| 🚀 Cross-Platform VS Code Integration | Open projects in VS Code/Insiders | Seamless workflow transition |

| 🛡️ Robust Error Handling | Handle network, permission, and path issues | Production-ready reliability |

📖 Step-by-Step Implementation

Step 1: Create GitHub Agent in Agent Builder

1. Launch Agent Builder through the AI Toolkit extension

2. Create a new agent with the following configuration:

```

Agent Name: GitHubAgent

```

3. Initialize custom MCP server:

- Navigate to Tools → Add Tool → MCP Server

- Select "Create A new MCP Server"

- Choose Python template for maximum flexibility

- Server Name: git_mcp_server

Step 2: Configure GitHub Copilot Agent Mode

1. Open GitHub Copilot in VS Code (Ctrl/Cmd + Shift + P → "GitHub Copilot: Open")

2. Select Agent Model in the Copilot interface

3. Choose Claude 3.7 model for enhanced reasoning capabilities

4. Enable MCP integration for tool access

> 💡 Pro Tip: Claude 3.7 provides superior understanding of development workflows and error handling patterns.

Step 3: Implement Core MCP Server Functionality

Use the following detailed prompt with GitHub Copilot Agent Mode:

Create two MCP tools with the following comprehensive requirements:



🔧 TOOL A: clone_repository

Requirements:

- Clone any GitHub repository to a specified local folder

- Return the absolute path of the successfully cloned project

- Implement comprehensive validation:

  ✓ Check if target directory already exists (return error if exists)

  ✓ Validate GitHub URL format (https://github.com/user/repo)

  ✓ Verify git command availability (prompt installation if missing)

  ✓ Handle network connectivity issues

  ✓ Provide clear error messages for all failure scenarios



🚀 TOOL B: open_in_vscode

Requirements:

- Open specified folder in VS Code or VS Code Insiders

- Cross-platform compatibility (Windows/Linux/macOS)

- Use direct application launch (not terminal commands)

- Auto-detect available VS Code installations

- Handle cases where VS Code is not installed

- Provide user-friendly error messages



Additional Requirements:

- Follow MCP 1.9.3 best practices

- Include proper type hints and documentation

- Implement logging for debugging purposes

- Add input validation for all parameters

- Include comprehensive error handling

Step 4: Test Your MCP Server

4a. Test in Agent Builder

1. Launch the debug configuration for Agent Builder

2. Configure your agent with this system prompt:

SYSTEM_PROMPT:

You are my intelligent coding repository assistant. You help developers efficiently clone GitHub repositories and set up their development environment. Always provide clear feedback about operations and handle errors gracefully.

3. Test with realistic user scenarios:

USER_PROMPT EXAMPLES:



Scenario : Basic Clone and Open

"Clone {Your GitHub Repo link such as https://github.com/kinfey/GHCAgentWorkshop

 } and save to {The global path you specify}, then open it with VS Code Insiders"

Expected Results:

4b. Test in MCP Inspector
