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 signed attestation: composite A-F ship-readiness grade + per-domain scores + ordered remediation. Dogfooding: the AINumbers server can attest itself."
