  "about": "MCP health receipts are the liveness record of the MCP servers listed on Rightshold: a background probe re-checks each listed server on a fixed cadence (at most three servers per pass, stalest first), and every probe is published as one append-only, hash-chained receipt — the time, the outcome, the latency, the tool count and the tool-definition fingerprint the server answered with. An outcome is a probe fact: up means the server's MCP handshake (initialize + tools/list) answered from this deployment at that time; down means it did not answer; redirected means the registered URL now redirects elsewhere, so the answer was not recorded as this server's; changed means it answered with tool definitions whose fingerprint differs from the recorded one. None of these is a finding that a server or its tools are safe. State transitions are also sealed into the public ledger as change observations; the full receipt history lives on this surface.",
  "note": "Probes run on the deployment's cadence, not on read: reading this surface never probes a server. A server with no receipts yet has not been probed since this record began — that is stated as an empty history, never filled in or back-dated.",
