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 | The template must reference each declared parameter as $name (binding, not interpolation). No response-level citation benchmark has verified this claim yet. | live_probe |
| security | sensitive_capabilities_declared | concern | 13 discovered tool(s) advertise potentially state-changing or privileged capabilities. Tool names: cypher_get_operator_onboarding_status, cypher_get_patron_onboarding_status, cypher_request_credential_channel, cypher_receive_credentials, cypher_forget_credentials, cypher_update_patron_credential, cypher_delete_patron_credential, cypher_get_patron_credential_fields, cypher_request_npub_proof, cypher_receive_npub_proof, cypher_delete_coupon, cypher_execute_query_by_key, cypher_delete_query. Classification is description-based and does not prove exploitability. Observed value: cypher_get_operator_onboarding_status, cypher_get_patron_onboarding_status, cypher_request_credential_channel, cypher_receive_credentials, cypher_forget_credentials, cypher_update_patron_credential, cypher_delete_patron_credential, cypher_get_patron_credential_fields, cypher_request_npub_proof, cypher_receive_npub_proof, cypher_delete_coupon, cypher_execute_query_by_key, cypher_delete_query Sample: n=13 | 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.
Share this server: permalink https://mcpqueen.com/s/io.github.lonniev/cypher-mcp · referral link https://mcpqueen.com/go/io.github.lonniev/cypher-mcp (counts as “routed via the queen”).
Live operational-grade badge, re-probed continuously — not a security or data-quality certification. Put it in your README and link to the complete receipt:

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.
Email alerts when the grade changes or the endpoint stops answering. Double-opt-in, one-click unwatch, free while in beta.
