Summary
Wraps the npm registry API to let Claude search packages, inspect dependencies, and pull download stats without leaving your editor. You get six tools: search by keyword, fetch package metadata (license, maintainers, versions), compare two packages side by side, list dependencies, check download counts across different time windows, and enumerate recent version history. No authentication required. Useful when you're evaluating libraries, checking bundle sizes before adding a dependency, or need current download trends to gauge package health. Works through stdio, so it runs via npx in Claude Desktop or Cursor without additional setup.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
