github-mcp

GitHub MCP server for Claude Code, Cursor, Cline, Windsurf, and any MCP-compatible client.

Exposes GitHub tools (issues, pull requests, code search, file content) to your LLM via the Model Context Protocol.

Features

• 🔁 Connection pooling & retry — single HTTP client per process, exponential backoff on 429/5xx, honors Retry-After.
• 🛡️ Typed errors — GitHubError carries HTTP status, parsed message, and endpoint.
• ✅ Input validation — catches bad inputs before the network round-trip.
• 📄 Text files decoded — get_file_content returns UTF-8 text under decoded_content for text files.
• 🧪 Fully tested — 75 mock-based tests, plus opt-in live integration tests.
• 🪶 Tiny — three runtime deps (mcp, httpx, pydantic); no PyGithub.
