description: "Rolls up caller-supplied yes/partial/no answers across six MCP ship-readiness sections (tool definitions, server.json/registry, OAuth 2.1, transport security, tool-poisoning hygiene, spec-revision compliance) into an overall 0-100 score and a prioritized gap list. Stage 4 (terminal) of the Agentic Policy Chain. Self-reported rollup; validate each weak section with its own deep-dive tool. Deterministic, zero PII."
