Connects Claude to the npm registry, Bundlephobia, and Snyk APIs to answer package questions without opening browser tabs. Exposes eight tools: search packages, compare download counts across multiple packages, check bundle sizes, scan for vulnerabilities, inspect dependency trees, and view download trends with sparklines. Useful when you're evaluating libraries and want to ask "compare zustand vs jotai" or "are there vulnerabilities in express" directly in your editor. No API keys required since it uses public endpoints. Works with Claude Desktop, Cursor, and any MCP client over stdio transport.
