A self-hosted alternative to the official GitHub MCP server, built for operators who switch between Claude Code, Cursor, Codex CLI, or other MCP clients and want the same personal access token to work everywhere. Exposes seven tools in v0.1: PR listing and merging, file read/write via the Contents API, Dependabot alert sweeps, and a health check that reports rate limit headroom. Written in Python on FastMCP with stdio transport. Ships with macOS Keychain integration so your PAT never touches process args or environment variables where ps aux or pgrep can leak it. Lighter tool surface than the official Go server but slots into the same install pattern as other community Python servers.
