faq

Should I install this MCP server?

Look it up first. You get healthy / issues / unknown from repo, package, and registry facts — not a pen-test. Try free →

Can my agent check automatically?

Yes. MCP tools census_search, census_lookup, and census_watch_* for per-server alerts. Docs →

What this is not

The MCP Census is a live registry health and identity check. It is not a full security audit, pen-test, compliance certification, or guarantee that a server is safe to run in production. Unknown means we lack evidence — not that the server is fine. Methodology →
