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: list_diagram_types List the 22 supported diagram/reference types with a one-line description and the local syntax reference URL for each | get_syntax_reference Get the syntax reference entry for one diagram type: description, a render-verified example, and the help page URL. No response-level citation benchmark has verified this claim yet. | 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/com.singsk/uml-plantuml · referral link https://mcpqueen.com/go/com.singsk/uml-plantuml (safe HTTPS redirect; GET does not write state).
Live operational-grade badge, re-probed continuously — not a security or data-quality certification. Copy the ready-made Markdown into your README:

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. Need recommendations and change review across several servers? Try the Scout + Guard pilot.
