Npm Plus

Npm Plus is an open-source MCP (Model Context Protocol) server that enables AI assistants and developer tools to research npm packages directly within their workflow. It provides powerful commands to search for npm packages, compare download counts, check bundle sizes, scan for known vulnerabilities, and inspect dependency trees—aggregating data typically found across multiple tools like npmjs, Bundlephobia, Snyk, and npm trends. Designed for developers and teams using editors like VS Code, Cursor, and Claude Desktop, it requires no API keys or signups and leverages only public npm registry APIs.
