GitHub MCP Server

🚀 GitHub MCP Server

A production-ready Model Context Protocol (MCP) Server built with Python that enables AI assistants and MCP clients to interact with GitHub repositories through the GitHub REST API.

This project demonstrates how to build a custom MCP server capable of performing GitHub operations such as listing repositories, retrieving repository information, managing issues, and extending to pull requests, workflows, and code management.

⚙️ Prerequisites

• Python 3.10+
• UV Package Manager
• GitHub Account
• GitHub Personal Access Token (PAT)
• Node.js (for MCP Inspector)

---

🔑 GitHub Token Setup

Generate a Personal Access Token from:

https://github.com/settings/tokens

Recommended permissions:

Repository Access
Issues: Read & Write
Contents: Read
Pull Requests: Read & Write

Create a .env file:

GITHUB_TOKEN=your_github_token_here

---

📦 Installation

Clone the repository:

git clone <repository-url>
cd github-mcp

Initialize project:

uv init

Install dependencies:

uv add mcp requests python-dotenv

---

▶️ Running the Server

Start the MCP server:

uv run server.py

The server will wait for MCP client connections.

---

🔍 Using MCP Inspector

Start MCP Inspector:

npx @modelcontextprotocol/inspector

Open:

http://localhost:6274

Connection Settings:

Transport : STDIO

Command:
uv

Arguments:
run server.py

Click Connect.
