Dep Tools MCP Server

mcp-dep-tools

MCP server providing dependency and package management tools for AI agents. Analyze licenses, find outdated packages, visualize dependency trees, estimate bundle sizes, and audit security vulnerabilities — all from your AI assistant.

Tools

dep_check_licenses

Analyze licenses of all dependencies in a project. Lists each dependency's license type, flags copyleft (GPL) and unknown licenses, and checks for compatibility issues.

dep_find_outdated

Check which dependencies are outdated. Compares installed or specified versions against the latest on npm, categorizes updates as major/minor/patch, and shows how many days since the latest version was published.

dep_analyze_tree

Build and display the dependency tree. Shows direct dependencies and their transitive sub-dependencies, calculates maximum depth, detects circular dependencies, and counts total transitive packages.

dep_analyze_size

Estimate total bundle size from package.json without installing node_modules. Queries the Bundlephobia API for each production dependency to get minified and gzipped sizes.

dep_security_audit

Check dependencies for known security vulnerabilities. Runs npm audit when a lockfile is present, otherwise queries the npm registry advisory API directly. Reports severity levels, affected version ranges, and fix recommendations.

Setup

npm install
npm run build
