An MCP initialize handshake against https://anansi-haven.anansidata.workers.dev/mcp completed on 2026-11-03 and listed 89 tools. One unpaid request to https://anansi-haven.anansidata.workers.dev/v1/paid/council_grade answered HTTP 402 with a payment payload we could parse (network eip155:8453, asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). No payment was sent: a 402 says the endpoint asked for money in a readable shape, not that paying works or that the seller delivers. The host serves an x402 capability manifest at /.well-known/x402. Listed from a maintainer submission; every field is self-reported except the checks above, which Sato Hub ran itself on 2026-11-03.

Answers a call

yes — list_rooms returned in 114 ms

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.
