Login-free handshake (initialize → tools/list; unpaid tools/call only on priced tools, to read the payment request; never paid, no credentials): automatic unauthenticated MCP handshake (initialize + tools/list), aiming for about once a day per listed server while we are still working through the registry; priority tier (host looked up via BotsRated preflight/check/report, or also a covered x402 seller, in the last 7 days) about every 6 hours; servers with no MCP answer for 7 days about every 4 days. States are factual: ok (initialize and tools/list answered), auth_required (HTTP 401/403: the server wants a login), handshake_failed (HTTP answer without a valid MCP result), unreachable (no HTTP answer), blocked (not contacted: the URL, a redirect or its DNS points to a private, local or otherwise non-public address, or to another host, which our rules don't allow). Names and descriptions are the registry's text; we don't check it.
