Documentation

npm-search-mcp

MCP server that searches npm packages and returns live registry data. No API key needed.

Tools

search_packages — Search npm for packages by keyword. Returns names, descriptions, download counts, and links.
get_package — Get detailed info about a specific package: version, dependencies, size, weekly downloads.
compare_packages — Compare 2-10 packages side by side with download stats, size, and quality scores.

Why?

AI coding assistants have stale knowledge about npm packages. This MCP server gives them live access to the npm registry — current versions, download trends, and package details updated in real-time.
