NPM Plus MCP Server

NPM Plus – Intelligent JavaScript Package Management for AI Assistants

NPM Plus is a production‑ready Model Context Protocol (MCP) server that gives AI assistants like Claude, Windsurf, Cursor, and VS Code direct, programmable access to the full lifecycle of JavaScript package management. Rather than relying on a developer’s local tooling, an AI can query the npm registry, inspect dependencies, and even modify a project’s with confidence that every operation will succeed or fail gracefully. This eliminates the friction of manual package troubleshooting and lets developers focus on higher‑level design while the AI handles routine, error‑prone tasks.

The server exposes a rich set of 16 fully operational tools. Search and metadata queries (, ) surface relevant libraries with intelligent relevance scoring, while analytics tools such as and provide insight into performance and popularity before a package is added. Management tools (, , ) support multiple registries (npm, Yarn, pnpm) and automatically detect the appropriate package manager. Robust retry logic and error handling mean that transient npm failures are retried, while clear messages guide the user when external APIs are unavailable. Security and compliance are baked in: , , and license utilities (, ) scan for known CVEs, suggest fixes, and ensure projects stay compliant with open‑source licenses.

Real‑world use cases abound. A developer can ask an AI to “add a state‑management library that supports TypeScript and has fewer than 10 k downloads,” and the assistant will search, evaluate bundle size, audit for vulnerabilities, and install the package with a single prompt. In continuous‑integration pipelines, an AI can automatically flag outdated or vulnerable dependencies and propose updates that preserve semantic versioning. For teams, the AI can generate dependency trees () and detect circular dependencies before code reviews, reducing merge conflicts.

Integration into AI workflows is seamless. Because NPM Plus adheres to MCP, any client that understands the protocol can invoke these tools via simple JSON payloads. The server’s tool lets developers confirm connectivity and version compatibility on the fly, while the utility keeps local registries lean. The result is a unified, AI‑driven experience that abstracts away the complexity of JavaScript package management while maintaining full control and transparency for developers.
