Description

This MCP server exposes tools to search and fetch detailed metadata from major package registries (NPM, crates.io, NuGet, PyPI, and Go modules). It provides search, package details, and version listing endpoints so agents can obtain real-time dependency, license, maintainer, and repository information. The server is designed to integrate with MCP-capable clients (Cursor, Claude, etc.), simplifying automated dependency lookup, package discovery, and verification tasks for agents.
