Sourced

Gives your coding agent read, grep, and glob access to the actual source code of every package on PyPI and npm. Instead of guessing what's inside a dependency or hunting through docs, you can search across 800,000+ Python packages and 3 million+ npm packages directly from your editor. New releases get indexed within 5 minutes. Useful when you need to understand how a library actually implements something, trace through unfamiliar code paths, or verify behavior before adding a dependency. Works with Claude Desktop, Cursor, VS Code, Windsurf, and others through the Model Context Protocol.
