description: "Combines the five MCP-dev checks: tool-definition lint (JSON Schema 2020-12), server.json validation (2025-12-11 schema), OAuth 2.1 audit (RFC 9728 PRM, RFC 8707 audience), tool-poisoning scan, and ops/readiness, into one self-reported conformance lint: composite A-F ship-readiness grade plus per-domain scores and ordered remediation. This is an unsigned lint result, not a signed attestation. audit_signature.signatures is empty by design, as it is on every unsigned OpenChainGraph node. Dogfooding: the AINumbers server can lint itself. Formerly named attest_mcp_server; that name remains accepted permanently."
