What is Mcp Npm_docs Server?

An MCP server that provides a tool to fetch metadata and documentation (including README content) for NPM packages. It uses the npms.io API and caches results locally with SQLite to improve performance. It is intended for developers using MCP clients (like Cline) who need programmatic access to package documentation.

How to use Mcp Npm_docs Server?

Install dependencies with npm install, build with npm run build, then run the compiled server with node dist/server.js. Configure caching via environment variables NPM_CACHE_TTL and NPM_CACHE_DB_PATH. Integrate with an MCP client by adding the server entry (using the absolute path to dist/server.js) to the client’s MCP settings file. The server exposes a single tool getNpmPackageDocs.
