PkgDiet MCP

PkgDiet is an MCP server and dependency policy tool for AI-assisted JavaScript and TypeScript development. It intercepts npm install, pnpm add, and yarn add commands generated by AI coding agents like Claude Code, Codex, Cursor, Windsurf, and Cline. By using native agent hook APIs, it blocks unapproved, deprecated, vulnerable, or typosquatted packages before they execute, ensuring safer dependency management.
