node-modules-inspector
Interactive UI for local node modules inspection
Node Modules Inspector is an MCP server and interactive developer tool that visualizes and analyzes node_modules dependencies in JavaScript projects. It provides both a web UI for exploring installed packages and an MCP server that exposes three dependency report tools (duplicates, sizes, maintainers) to AI coding agents over stdio. The tool supports pnpm, npm, and bun projects, offering developers insights into package versions, bundle sizes, and upgrade opportunities through both human-readable tables and machine-parseable JSON output.
