## How to install or connect

Run it with npx over stdio; the package coordinate is available through the API.

## What the checks mean

`alive` combines the applicable repository, package, and endpoint checks. A null result is not verifiable, not a failure. The MCP handshake is a separate structural probe and is not a security audit. Methodology: https://labs.lubbee.net/methodology/
