jCodemunch MCP

The most token-efficient MCP server for precise source code retrieval via tree-sitter AST parsing. Cut AI token costs 86-99% on code exploration (96% average, benchmarked at 27.9x fewer tokens than a grep-and-read agent) and stop burning your context window reading entire files. It runs locally over stdio via the published package.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package jcodemunch-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.jgravelle is GitHub-verified and matches the repo owner
