vet402-check — questions

Answers built from our own checks of this server.

Why is there no uptime for vet402-check?

vet402-check runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @vet402/check was installed 488 times last week.

How do I connect vet402-check?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @vet402/check straight from npm; nothing to host, nothing to sign up for.

How many people use vet402-check?

The npm package @vet402/check was installed 488 times in the last week. Week over week that is +68%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is vet402-check open source?

Yes — it is published under the MIT licence, written in HTML and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
