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: pon_id becomes a no-op (the constraint returns neutral on unknown ids) — the Studio surfaces orphan references as warnings. No response-level citation benchmark has verified this claim yet. | live_probe |
| security | sensitive_capabilities_declared | concern | 11 discovered tool(s) advertise potentially state-changing or privileged capabilities. Tool names: schwab_get_operator_onboarding_status, schwab_get_patron_onboarding_status, schwab_request_credential_channel, schwab_receive_credentials, schwab_forget_credentials, schwab_update_patron_credential, schwab_delete_patron_credential, schwab_get_patron_credential_fields, schwab_request_npub_proof, schwab_receive_npub_proof, schwab_delete_coupon. Classification is description-based and does not prove exploitability. Observed value: schwab_get_operator_onboarding_status, schwab_get_patron_onboarding_status, schwab_request_credential_channel, schwab_receive_credentials, schwab_forget_credentials, schwab_update_patron_credential, schwab_delete_patron_credential, schwab_get_patron_credential_fields, schwab_request_npub_proof, schwab_receive_npub_proof, schwab_delete_coupon Sample: n=11 | 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.

Think the grade is wrong? Fix the finding the evidence shows, then the next probe cycle picks it up automatically (full cycle ≈ 3 days) — or open a dispute via the MCP endpoint.
