NPMJS MCP Server

What is NPMJS Model Context Protocol (MCP) Server?

A lightweight, TypeScript-based MCP server that provides structured information about npmjs packages—such as version details, download statistics, publish dates, descriptions, and licenses—in a standardized JSON format for consumption by LLMs and AI-driven development tools. It abstracts away direct interactions with multiple npmjs API endpoints.

How to use NPMJS Model Context Protocol (MCP) Server?

Clone the repository, run npm install, then start the server in development with npm run dev or in production with npm start after building with npm run build. The server listens for MCP requests via standard input/output and exposes tools that can be called using any MCP client. Each tool requires a JSON object with a packageName argument (e.g., { "packageName": "express" }).
