💡 Why GitHub MCP?

Have you ever faced these challenges?

• ❌ Repetitive Work: Manually checking, creating, and updating Issues and Pull Requests every day
• ❌ Low Efficiency: Constantly switching between command line and browser
• ❌ Collaboration Difficulties: Team members need a unified way to operate GitHub

GitHub MCP solves all of this!

✅ Let Claude, ChatGPT and other AI assistants directly operate GitHub
✅ No need to leave the conversation interface, complete tasks with one sentence
✅ Based on Model Context Protocol, secure and reliable
✅ Fully open source, easily extensible with new features

⚡️ Quick Start (3 Steps)

Step 1: Install

npm install github-mcp

Or install globally:

npm install -g github-mcp

Step 2: Get GitHub Token

1. Visit GitHub Settings > Personal Access Tokens
2. Click "Generate new token (classic)"
3. Check repo permission (for accessing repository information)
4. Copy the generated Token

Step 3: Start the Server

# Set environment variable
export GITHUB_ACCESS_TOKEN="your_github_token_here"

# Start the server
npx github-mcp

🎉 Done! Now your AI assistant can operate GitHub!

Alternative Transport: Streamable HTTP (Hono)

Need an HTTP/SSE endpoint instead of STDIO? Start the Hono-powered Streamable HTTP server:

npx github-mcp streamableHttp

Or enable it via environment variables:

MCP_TRANSPORT=streamableHttp STREAMABLE_HTTP_PORT=3001 npx github-mcp

The Hono server exposes /mcp for POST/GET/DELETE requests, automatically handles CORS, and keeps SSE streams open for real-time messaging. It still reuses the same GitHubMCPServer logic from STDIO, so your tools and configuration behave identically.

Tip: You can start the server even without a Token, authentication is only required when calling GitHub APIs.

🎯 Use Cases

Scenario 1: Quickly View Issue List

Traditional Way:

1. Open browser
2. Log in to GitHub
3. Find the repository
4. Click Issues tab
5. Manually filter and view

With GitHub MCP:

You: Help me check what unresolved Issues are in Seey215/github-mcp repository
AI:  Querying... Found 3 unresolved Issues:
     1. #12 - Add Pull Request management feature
     2. #10 - Support GitHub Actions trigger
     3. #8 - Optimize error messages

Scenario 2: Batch Process Issues

You: Mark all Issues with "bug" in the title as high priority
AI:  Added high priority label to 5 Issues

Scenario 3: Automated Workflows

You: Summarize new Issues from yesterday every morning at 9 AM
AI:  Scheduled task created, will send daily report via email

📚 Detailed Usage Guide

Running as MCP Server (Recommended)

This is the most common usage, suitable for integration with AI tools like Claude Desktop, Continue, etc.

Configure Claude Desktop:

Edit the configuration file ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y", "github-mcp"],
      "env": {
        "GITHUB_ACCESS_TOKEN": "your_token_here"
      }
    }
  }
}

Restart Claude Desktop, and you can use GitHub features in conversations!

Using as Node.js Library

If you want to use it in your own project:

import { GitHubMCPServer } from 'github-mcp';
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";

// Create server instance
const server = new GitHubMCPServer({
  token: 'your_github_token',
  serverName: 'my-custom-server',
  serverVersion: '1.0.0'
});

// Connect transport layer
const transport = new StdioServerTransport();
await server.connect(transport);

console.log('GitHub MCP Server started!');

Configuration Options

GitHubMCPServer supports the following configuration:

interface GitHubConfig {
  token?: string;           // GitHub Personal Access Token
  apiBase?: string;         // API base URL (default: https://api.github.com)
  apiVersion?: string;      // API version (default: 2022-11-28)
  serverName?: string;      // Server name (default: github-mcp-server)
  serverVersion?: string;   // Server version (default: 1.0.0)
}

Configuration Priority: Constructor parameters > Environment variables > Default values

Design Principles

• Single Responsibility: GitHubMCPServer focuses on GitHub API integration
• Encapsulation: Private methods hide implementation details
• Configurability: Flexible constructor supports multiple configuration methods
• Extensibility: Clear structure makes it easy to add new tools
• Lazy Validation: Token is only validated when using API, improving user experience

❓ FAQ

Q: Why not validate Token at startup?

A: For better user experience! Even without a Token, you can:

• View all available tools
• Understand each tool's functionality
• Use them when Token is ready

Q: Is the Token secure?

A: Yes! The Token is only stored in local environment variables and is never uploaded or shared. Recommendations:

• Use Fine-grained tokens to limit permission scope
• Rotate Token regularly
• Never hardcode Token in public code

Q: Does it support GitHub Enterprise?

A: Yes! Just configure a custom API address:

const server = new GitHubMCPServer({
  apiBase: 'https://github.your-company.com/api/v3',
  token: 'your_token'
});

Q: How to debug?

A: Use the demo file for testing:

# Set Token
export GITHUB_ACCESS_TOKEN="your_token"

# Run test
npx tsx demo.ts

Q: What about API rate limiting?

A: GitHub API has rate limits:

• Unauthenticated: 60 requests/hour
• Authenticated: 5000 requests/hour

Recommended to use Token for higher quota.
