Connects Claude to the npm registry for package intelligence without leaving your editor. Exposes search, security audits, bundle size analysis, peer dependency validation, and package comparison. The standout feature is automatic security checking: Claude scans packages for vulnerabilities before suggesting installation, no prompting needed. You also get ESM/CJS compatibility detection, TypeScript support checks, and side-by-side comparisons of alternatives. Useful when evaluating dependencies, troubleshooting version conflicts, or vetting unfamiliar packages. Ships as an npx command, so no global install required. Just wire it into your Cursor or Claude Desktop config and start asking about packages.
