Remote MCP server host. 1 server URL from the Official MCP Registry. Each is checked with a login-free MCP handshake (initialize, then tools/list; unpaid tools/call only on tools that state a price, to read the payment request; nothing is paid, no credentials are sent): 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 unsafe address, or to another host, which our safety rules don't allow). Server names and descriptions are copied from the registry (untrusted text). Friendlier view: /s/stock-signal-us.airblock2026.workers.dev.

From our unpaid check: the tool list, plus at most 2 unpaid calls to tools that state a price, only to read the payment request. We never pay and never call tools that don't state a price. Stated prices are the server's own text or metadata. Full details: free quick check (JSON).
