Package Health MCP server

pkg-health-mcp

Is this dependency still maintained? Find out before you install it.

pkg-health-mcp scores npm packages, PyPI packages and GitHub repositories from 0 to 100 for maintenance health. It combines release and commit activity, active maintainers, issue response times, download trends, OpenSSF Scorecard and license into an A–F grade and a plain-language list of risks.

Use it three ways, all built on the same engine:

• MCP server for Claude Code, Claude Desktop, Cursor, VS Code and any other MCP client, so your AI agent checks a package before it suggests one.
• CLI to audit a manifest or lock file, including transitive dependencies.
• GitHub Action to add a health report to every pull request and fail the build below a threshold.

Why

A typical project pulls in hundreds of open-source packages. Some of them are quietly abandoned: no releases for years, one maintainer who moved on, issues piling up unanswered. When a vulnerability shows up in one of those, nobody fixes it.

Checking this by hand means opening each package's GitHub page and reading commit dates, issue lists and contributor graphs. Nobody does that for every dependency, and AI coding assistants never do it: they happily suggest whatever library was popular in their training data, including ones deprecated years ago.

pkg-health-mcp makes that check a single tool call, so:

Shortened. The full README is on GitHub.
