FAQ from Package Registry Mcp Server

What runtime is required?

Node.js 18+ or Bun runtime, plus an internet connection for registry access.

Can I use it without installing?

Yes. Run with npx package-registry-mcp — no global installation needed.

Does it support searching all registries?

No. PyPI and Go module search are not supported because those registries lack a JSON search API; only detail and version listing are available.

How do I configure it with Claude Desktop?

Add the server to claude_desktop_config.json with "command": "npx" and "args": ["package-registry-mcp"]. The config file location depends on your OS.

What data does it return?

Package metadata (name, description, version, license), dependencies, download statistics, maintainer info, and last 50 versions. Advisories include GHSA ID, CVE ID, severity, CVSS score, affected ranges, and patched versions.
