Which integrations are available for this server?

Enables token-efficient exploration and indexing of GitHub repositories, allowing for symbol searching, file structure retrieval, and extraction of specific code definitions like functions and classes.

How do I use github-codemunch-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@github-codemunch-mcp search for the 'authenticate' function in the 'pallets/flask' repository" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

github-codemunch-mcp

Token-efficient MCP server for GitHub source code exploration via tree-sitter AST parsing.

Overview

github-codemunch-mcp pre-indexes repository source code using tree-sitter AST parsing, extracting a structured catalog of every symbol (function, class, method, constant, type). Each symbol stores only its signature + one-line summary, with the ability to retrieve full source on demand.
