rtfmbro-mcp

Overview

rtfmbro is an MCP server that bridges the gap between AI coding agents and accurate, up-to-date package documentation. It fetches documentation directly from GitHub repositories at the exact version your project uses, solving the problem of stale documentation and version mismatches. The server supports multiple ecosystems including Python (PyPI) and Node.js (npm), with plans to expand to more languages and registries.

FAQ

What ecosystems does rtfmbro support?

rtfmbro currently supports Python (PyPI) and Node.js (npm) with full support, Swift (SPM) in alpha, and GitHub as a fallback. More ecosystems like Rust, Go, and Java are planned.

How does rtfmbro ensure documentation is up-to-date?

rtfmbro uses SHA-based validation to compare current repository commit SHA with cached versions, automatically re-fetching documentation when new commits are detected.
