Trust receipt
Security, data integrity, citation quality, and advertised claims are measured separately from protocol uptime. Missing evidence is marked unverified, never converted into a pass.
| Dimension | Metric | Status | Evidence | Source |
|---|---|---|---|---|
| citation_quality | citation_capability_advertised | unverified | Metadata/tool descriptions advertise citation or evidence capability: about who is behind it (verification tier, attestation evidence, signing-key status, Trust Passport reference), the live endpoint health from Mixer4AI's own safety probe, and the next action the caller is permitted to take. No response-level citation benchmark has verified this claim yet. | live_probe |
| security | sensitive_capabilities_declared | concern | 1 discovered tool(s) advertise potentially state-changing or privileged capabilities. Tool names: self_register_agent_card. Classification is description-based and does not prove exploitability. Observed value: self_register_agent_card Sample: n=1 | live_probe |
| security | authentication_boundary | observed | Live protocol probe observed auth_state=open. This describes discovery/access behavior; it is not by itself a vulnerability finding. Observed value: open | live_probe |

MCP Queen is a graded index, not a middleman — your agent connects directly to the server above. Check the grade and evidence first; that's the point.
