概要

What is Package Registry Mcp Server?

A Model Context Protocol (MCP) server that enables AI assistants (Claude, Cursor, Copilot, etc.) to search package registries and retrieve up-to-date package information. It supports npm, crates.io, NuGet, PyPI, Go modules, and GitHub Security Advisories.

How to use Package Registry Mcp Server?

Install globally with npm install -g package-registry-mcp or run directly with npx package-registry-mcp. Configure as an MCP server in Cursor Settings, Claude Code via claude mcp add, or add to claude_desktop_config.json with command npx and args ["package-registry-mcp"].

Key features of Package Registry Mcp Server

  • Search and get details for multiple package registries.
  • Retrieve latest version and version history for any package.
  • Search GitHub Security Advisories for known vulnerabilities.
  • Get advisory details and per-package vulnerability reports.
  • Real-time data fetched directly from official registries.

よくある質問

1

What runtime is required?

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

2

Can I use it without installing?

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

3

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.

4

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.

5

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.
