Npm Plus

Npm Plus is an MCP server that enables AI assistants or MCP-compatible clients to research npm packages programmatically and conversationally. It offers features like package search, bundle size lookup, vulnerability scans, download comparisons, and dependency tree visualization—all with no API keys required. Designed for developers and users of AI code assistants, it streamlines npm research inside tools like Claude Desktop, Cursor, and VS Code Copilot.
