mcp-package-health

An MCP (Model Context Protocol) server that gives AI agents real-time package health data, vulnerability reports, and dependency graphs — directly inside Claude, Cursor, and any MCP-compatible client.

Why this exists

Every developer has asked Claude something like "is this package still maintained?" or "does this version have any CVEs?" — and Claude has to say "I don't have real-time data."

mcp-package-health fixes that. It exposes three tools that any MCP-compatible AI agent can call live:

Related MCP server: @lpm-registry/mcp-server

Install

pip install mcp-package-health

Or from source:

git clone https://github.com/fse08877-netizen/mcp-package-health.git
cd mcp-package-health
pip install -e ".[dev]"

Usage with Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "package-health": {
      "command": "mcp-package-health"
    }
  }
}

Then ask Claude:

• "Is numpy safe to use at version 1.24.0?"

• "What are the dependencies of fastapi?"

• "When was the last release of httpx?"
