Gread

This gives AI agents direct access to source code from any public GitHub repository through either MCP or Skill integration. It clones repos server-side for fast git-based operations, includes tools for listing directory trees and searching code, and automatically pulls in documentation repos when available. Unlike API-based solutions, the local caching means quick responses after initial indexing. Reach for this when you need your coding agent to reference implementation details across multiple libraries simultaneously, or when you want Claude to read through a project's actual source instead of just documentation. The service is free and runs at api.gread.dev/mcp, so you can skip self-hosting entirely.
