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: Returns answer with numbered citations | Returns paginated results with text, citation, court, relevance score, snippet, PDF | ast compact **Indian** legal case search returning top 3-5 results with just the essentials: title, citation, court, year, summary excerpt, and PDF link. 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 |
| citation_quality | identifier_resolvability:ask_legal_question | not_testable | No PMID or DOI was exposed, so citation validity could not be tested. Observed value: 0/0 Sample: n=3 | response_benchmark |
| citation_quality | citation_identifier_presence:ask_legal_question | concern | 0 of 3 benchmark queries exposed at least one machine-resolvable PMID or DOI; 0 identifiers observed. Observed value: 0/3 Sample: n=3 | response_benchmark |
| security | tool_access_boundary:ask_legal_question | observed | Observed HTTP status distribution across 3 actual tool calls: 200×3. Open initialize/tools-list does not imply open data-tool access. Observed value: {"200":3} Sample: n=3 | response_benchmark |
| data_integrity | response_success_rate:ask_legal_question | pass | 3 of 3 controlled read-only calls returned a non-error MCP tool result. Observed value: 3/3 Sample: n=3 | response_benchmark |
