One MCP handshake with the listed endpoint (server/discover at 2026-07-28, then initialize for a server on the older revision), with no credential and no retry, identifying itself as agentwares-mcp-liveness/0.1 (+https://agentwares-agentcheck.vercel.app/bot). It runs when this page is requested and the result is reused for 10 minutes, so the time above is when it was taken.
Live status every few hours: Wellknown
Email me when this server changes
That was one look. To hear when it stops answering or its tools change, leave an address.
Free, no password or GitHub: one confirmation email first, then a check every hour and an email when it stops answering or its tools change. Every email has a link to stop. More about it.
