Rtfmbro is a Model Context Protocol (MCP) server designed to bridge the gap between AI agents and accurate package documentation. By fetching documentation directly from GitHub repositories at the exact version used in a project, it ensures AI models have access to the most relevant and up-to-date information, preventing errors caused by stale or mismatched documentation. It supports multiple ecosystems including Python (PyPI), Node.js (npm), and Swift (SPM), intelligently caching documentation to optimize performance and seamlessly integrates with AI coding assistants.
