GitHub MCP Server

A lightweight Model Context Protocol (MCP) server that provides structured access to GitHub repository data for AI agents.

This project enables AI systems to work with real GitHub data instead of relying on assumptions or hallucinated information.

📌 What Problem Does This Solve?

Manually analyzing GitHub repositories is:

• Time-consuming
• Inconsistent
• Error-prone

AI systems often hallucinate repository details such as structure or documentation.

This MCP server solves that problem by exposing GitHub as reliable, AI-callable tools.

🧠 What is MCP?

Model Context Protocol (MCP) standardizes how AI models interact with external tools and data sources.

• MCP ensures correctness
• AI agents handle reasoning and decision-making

🚀 Features

This GitHub MCP Server allows AI agents to:

• List public repositories of a GitHub user
• Fetch README documentation of a repository
• Access real-time GitHub data in a structured format
• Avoid hallucinated or outdated repository information

🛠️ Available Tools

🔹 github-mcp:list_repositories

Description:
Lists all public repositories of a given GitHub user.

Input:

{
  "username": "torvalds"
}

Output:

[
  {
    "name": "linux",
    "url": "https://github.com/torvalds/linux"
  }
]

🔹 github-mcp:get_readme

Description: Fetches and returns the README content of a repository.

Input:

{
  "owner": "torvalds",
  "repo": "linux"
}

Output: Decoded README markdown text.

⚙️ Setup Instructions

1️⃣ Install dependencies

npm install

2️⃣ (Optional) Set GitHub Token

For higher rate limits or private repositories:

export GITHUB_TOKEN=your_token_here

3️⃣ Run MCP Server

node index.js

The server runs via STDIO and waits for MCP client requests.

🔌 Supported MCP Clients

• Claude Desktop
• Cursor IDE
• Continue.dev
• Any MCP-compatible client

🔐 Authentication Notes

• Public repositories: No authentication required
• Private repositories: GitHub Personal Access Token required

🚧 Limitations

• Does not perform deep code analysis
• Does not modify repositories
• Provides repository data access only

🌱 Future Enhancements
