Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 916 tokens (~114/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

batch_verify_citations Verify legal citations across multiple texts (batch) ~138
Runs the same 3-layer citation verification as verify_citation across multiple texts in a single call. Each item is billed against your CitationSafe usage exactly like an individual verify_citation call — batching never bypasses your plan's monthly limit. Max 10 items per batch, 64,000 characters per item. Requires a signed-in CitationSafe account (Authorization: Bearer <access_token>) — anonymous batch calls are not supported, use verify_citation for anonymous single-text checks.
| Name | Type | Req | Description |
|---|---|---|---|
| texts | array | yes | Array of texts to verify, each processed as a separate verification (max 10 items, 64,000 chars each) |
No output schema declared.
No examples provided.
get_verification Get a past CitationSafe verification report by ID ~61
Retrieves a previously run CitationSafe verification (by the verificationId returned from verify_citation/verify_document, or from a citationsafe.com/v/{id} share link) and returns its full per-citation results.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Verification ID |
No output schema declared.
No examples provided.
is_this_case_real Check whether a single case citation is real ~154
Deterministic existence check (Layer 1 only, no LLM) for one legal citation against CourtListener's primary-source database. Answers the single question "is this case real" for one citation — for multi-citation quote-checked verdicts across a whole brief, use verify_brief instead. Free tier: 5 checks/day per IP, no key required. For unlimited access, pass an API key as "Authorization: Bearer <key>" (contact [email protected] to request one).
| Name | Type | Req | Description |
|---|---|---|---|
| citation | string | yes | A single citation, e.g. "410 U.S. 113" or "Roe v. Wade, 410 U.S. 113 (1973)" |
No output schema declared.
No examples provided.
search_phantoms Search known AI-hallucinated (phantom) case citations ~98
Searches CitationSafe's phantom-citation registry — fabricated case names/citations that have shown up in real, sanctioned AI-hallucination incidents — by case name or the AI system that produced them. Read-only, public data. Returns an empty array (not an error) if nothing matches or the registry has no entries yet.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Free-text match against the phantom case name or the AI system that generated it |
No output schema declared.
No examples provided.
search_sanctions Search the AI-hallucination court sanctions database ~102
Searches CitationSafe's database of real court sanctions/orders arising from AI-hallucinated legal citations, by court name, party/case name keyword, or free-text keyword. Read-only, public data — same dataset backing citationsafe.com/sanctions-database.
| Name | Type | Req | Description |
|---|---|---|---|
| court | string | — | Filter by court name (partial match, e.g. "S.D.N.Y.") |
| query | string | — | Free-text keyword to match against the case name |
No output schema declared.
No examples provided.
verify_brief Verify every citation in a brief or excerpt ~153
Runs existence (Layer 1) and quote-match (Layer 2) checks — both deterministic, no LLM — on every citation found in the given text and returns one verdict per citation. The multi-citation counterpart to is_this_case_real. Proposition support (Layer 3) is not included on this free/API-key surface; sign in at citationsafe.com for full 3-layer verification via verify_citation. Free tier: 5 checks/day per IP (one verify_brief call = one check, regardless of how many citations the text contains); an API key bypasses the daily cap.
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | Raw text (brief excerpt, motion, memo) containing one or more legal citations |
No output schema declared.
No examples provided.
verify_citation Verify legal citations in text ~134
Checks every legal citation in the given text against primary sources: does the cited case exist (Layer 1, CourtListener database lookup — deterministic, no LLM), does a quoted passage appear in the source opinion (Layer 2), and — on paid CitationSafe tiers — does the case support the proposition it's cited for (Layer 3). Returns VERIFIED / UNCONFIRMED / UNCONFIRMED — OUTSIDE COVERAGE / SOURCE UNAVAILABLE per citation, never a bare true/false, with source links. Not legal advice.
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | Raw text containing one or more legal citations to verify |
No output schema declared.
No examples provided.
verify_document Verify legal citations in a document URL ~76
Fetches a document (PDF, DOCX, or plain text) from a URL and runs the same 3-layer citation verification as verify_citation. Use this when you have a link to a brief rather than pasted text.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | URL of the PDF, DOCX, or text document to fetch and verify |
No output schema declared.
No examples provided.
