Provides a single powerful interface to GitHub's GraphQL API, enabling comprehensive interaction with repositories, issues, pull requests, and other GitHub resources with smart abstractions for authentication and data handling.
Exposes GitHub's GraphQL API as the primary interface, allowing flexible querying and manipulation of GitHub data through GraphQL queries and mutations.
Refined MCP server for GitHub
If you haven't read the articleThe second wave of MCP: Building for LLMs, not developers by Vercel, I highly recommend checking it out to understand why we're building this project.
GitHub's official MCP Server exposes dozens of low-level tools that bloat token usage and are mostly impractical for LLMs. gh-mcp achieves the best of both worlds by providing powerful interfaces: GitHub GraphQL and Code Search, wrapped with smart abstractions.
This project does 3 things differently:
Powerful interfaces — exposes GraphQL and Code Search instead of atomized endpoints. LLMs already understand these APIs.
YAML output — makes nested data and file content readable without escaping.
Clean abstractions —
ghhandles authentication and low-level details. And LLMs know how to use its--jqoption to filter.
Swapping in gh-mcp delivers better performance at lower cost for any GitHub interactions.
Installation

If you prefer serving it via streamable-http:
This project requiresgh CLI to be installed and authenticated. Please follow the instructions at cli.github.com to set it up. And then you can login via gh auth login. Check that gh auth status works before using this MCP server.
