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.

Monthly census, 6 October 2026
The census sends the same request to every remote listing in the official registry once a month. On 6 October 2026 this one answered a stock client with no credential. Every listing’s result: index.ndjson (what the files hold: index.meta.json).
