    "headline": "An MCP discovery and evidence layer with real corpus scale and — rarest of all in this category — an explicit statement of what its grades do NOT mean.",
    "body": "MCP Queen indexes the MCP server ecosystem and attaches dated operational evidence to what it finds: 18,849 servers indexed, 9,326 graded live, plus separate Trust Receipts, field reports, and a published State of the MCP Ecosystem report whose lead finding (1 in 6 remote servers is dead) is the kind of unflattering number that suggests the measurement is real rather than promotional. The scoping discipline is what stands out. The site states plainly that \"an operational grade is not a security certification\", separates discovery from evidence from receipts rather than collapsing them into one number, and frames itself as \"an experiment by Health AI\" instead of overclaiming institutional authority. That is the correct posture for a rating layer, and we say so as a party with an obvious interest in the same discipline. What is missing is the layer beneath the claim: the grading methodology is not visible on the surface we captured, so a reader cannot yet tell what a grade measures or how it could be gamed; there is no independent validation of the index; and the self-description as an experiment leaves continuity genuinely uncertain for anyone who would depend on it. STEADY on scope, honesty and corpus size — with the caveat that a grading system is only as good as the method it will not show you.",

  "tier_rationale": "STEADY (76) for corpus scale (18,849 indexed / 9,326 graded), a published ecosystem report with a falsifiable headline finding, and unusually disciplined scoping — it states outright that an operational grade is not a security certification and keeps discovery, evidence and receipts as separate layers. Held below VITAL because the grading methodology is not exposed on the public surface, there is no third-party validation of the index, and the project describes itself as an experiment, which makes continuity uncertain.",
