## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-24.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 75/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1146 tokens (~71/item across 16 items; 16 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 57/100
  - Stability observed for 17 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 72/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 15% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 16 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 16 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## MCP tools (16)

### `list_modules` (~26 tokens)

List every clinician teaching module and patient chapter: title, canonical URL, evidence-review date.

### `search_teaching` (~49 tokens)

Search clinician teaching modules AND patient chapters by free-text query (title, description, and body text); returns matching modules with snippets.

Input parameters:

- `limit` (number)
- `query` (string, required)

### `read_module` (~35 tokens)

Read ONE module's full teaching text (markdown) with required citation. Not for bulk corpus assembly.

Input parameters:

- `slug` (string, required)

### `get_claims` (~33 tokens)

Get the claim ledger (claim → evidence rows) for a module, when published.

Input parameters:

- `slug` (string, required)

### `get_evidence_log` (~19 tokens)

Dated evidence-review log for all modules.

### `get_corpus_state` (~46 tokens)

The current GASTROLOGER_CLINICAL_STATE: version, corpus/section/module Merkle roots, counts and hash scheme — pin an answer to an exact knowledge state.

### `verify_claim_hash` (~67 tokens)

Verify one clinical claim against the published corpus root via its Merkle inclusion proof (optionally against a bundle_hash you hold). Returns the claim content only when it is physician-activated or clinician-adjudicated.

Input parameters:

- `bundle_hash` (string)
- `claim_id` (string, required)

### `check_gi_claim` (~63 tokens)

Fact-check pasted text (a social post, caption, or sentence): canonical wording or its full explicit negation can receive a scoped governed verdict; other matches return unresolved reviewed candidates with evidence. No video retrieval or individual medical advice.

Input parameters:

- `text` (string, required)

### `resolve_gi_claim` (~52 tokens)

Resolve one supplied proposition against governed claims. Only preserved canonical wording or its full explicit negation is certified; lexical candidates and changed qualifiers remain unresolved. Does not search external evidence.

Input parameters:

- `claim` (string, required)

### `search_gi_verifications` (~47 tokens)

Search canonical GI fact-check verifications by free text; returns matching governed claims with canonical /verify/ URLs.

Input parameters:

- `limit` (number)
- `query` (string, required)

### `get_gi_verification` (~44 tokens)

Get one canonical verification record (statement, verdict, review date, evidence module, machine URLs) by its slug or claim id.

Input parameters:

- `slug` (string, required)

### `get_evidence_bundle` (~114 tokens)

Resolve up to 10 claims (by claim_ids or free-text query) into an evidence bundle: statements, verdicts, review dates, evidence pointers, canonical URLs, clinical-state pin. Optional locale (BCP-47) reports human-localized module availability; canonical identifiers are language-independent. Bulk export beyond 10 claims is the paid tier (x402) at /api/premium/evidence-pack.

Input parameters:

- `claim_ids` (array)
- `locale` (string)
- `query` (string)

### `classify_hrm_metrics` (~85 tokens)

Legacy HRM operation quarantined after rule discrepancies were reproduced against reviewed teaching. Returns needs_review without classification. Do not invoke to obtain a diagnosis; this compatibility name is omitted from new plugin products.

Input parameters:

- `manufacturer` (string)
- `metrics` (object, required)
- `position` (string)
- `provocative` (object)
- `secondary_testing` (object)

### `score_clinical_instrument` (~157 tokens)

Score a governed clinical instrument from structured responses: IBS-SSS (ibs-sss, 5 slider items 0-100 + days×10, total 0-500) and GERD-Q (gerd-q, 6 choice items, total 0-18, ≥8 consistent with GERD). Returns total, percent of max, band label + interpretation, and the instrument citation. Every item is required; invalid/missing responses are rejected without defaulting or clamping. Educational scoring — not a diagnosis. Also POST /api/tools/score-instrument.

Input parameters:

- `instrument` (string, required)
- `responses` (object, required): item_id → numeric value (see instrument spec at /tools/instruments.json)

### `query_relations` (~188 tokens)

Query the evidence-backed clinical relationship graph (subject–predicate–object triples over diseases, medications, tests, findings, guidelines). Every relation cites governed claim IDs and/or evidence registry IDs. Filter by node text (subject/object), predicate (treated_by, evaluated_by, contraindicated_by, increases_risk_of, reduces_risk_of, causes, associated_with, suggests, argues_against, complicated_by, recommended_by, supported_by, conflicts_with, supersedes, requires_context_of), kind, or a claim_id. Also GET /api/tools/relations.

Input parameters:

- `claim_id` (string)
- `kind` (string): filter subject_kind or object_kind (disease, medication, test, finding, guideline, risk_factor, mechanism, intervention)
- `limit` (number)
- `node` (string): substring match against subject_id/object_id
- `predicate` (string)

### `resolve_ask` (~121 tokens)

Route a free-text GI ask to the Gastrologer object that owns it: a governed claim, teaching module, instrument (IBS-SSS/GERD-Q), atlas region, prep-timeline workflow, or relationship. Returns a confidence-ordered routing decision (resolved | ambiguous | needs_review) with canonical URLs — it routes, it does not answer. Unmatched asks are recorded as coverage-gap signals that drive what the corpus builds next.

Input parameters:

- `ask` (string, required): free-text information need, e.g. "current guidance for Barrett's surveillance"
