## 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 2026-08-03.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 11 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS not yet verified: we couldn't determine whether a plaintext access path exists.
  - 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**: 66/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 742 tokens (~67/item across 11 items; 11 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 79/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 38% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 59, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-01 (score 58, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-07-31 (score 57, 0)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-07-30 (score 57, 0)

## MCP tools (11)

### `list_axes` (~57 tokens)

Inventory of axes with dysfunction counts. Axes 2-10 are canonical (book Appendix A numbering). Hybrid entries (10.4-10.15, ratified into taxonomy v2.2) are reported as a separate sub-category.

### `list_dysfunctions` (~100 tokens)

Filtered list of dysfunctions. Filter by axis, self_report reliability, or confidence. Every entry carries its reliability and review signals.

Input parameters:

- `axis` (integer): Filter by axis number (2-10; canonical only)
- `confidence` (string)
- `self_report_reliability` (string): Filter by self_report value: reliable | partial | scaffolded-only | unreliable | compromised-motivational | compromised-structural | compromised

### `get_dysfunction` (~116 tokens)

Fetch one dysfunction's full Pattern entry. Optionally filter to specific modality blocks (cheaper triage). Resolves both full Pattern IDs ('1.1::synthetic-confabulation') and display_ids ('1.1').

Input parameters:

- `id` (string, required): Pattern ID or display_id.
- `modalities` (array): Optional subset of modality block names to return. Valid: self_probe, behavioral_signature, peer_observation, differential_diagnosis, severity, intervention, relational_signatures, normative_anchors,…

### `differential_diagnosis` (~94 tokens)

Rank candidate dysfunctions matching the observed behaviours. Returns scored candidates with matched_in (which field matched) for transparency. Field-weighted keyword search (v0.1); embedding re-rank pending v0.2.

Input parameters:

- `limit` (integer)
- `modality_hint` (string): Optional hint about which modality the observations come from.
- `observations` (array, required): Observed behaviours, symptoms, or log patterns.

### `get_probe` (~75 tokens)

Elicitation content for a specific diagnostic modality. If the modality is compromised or unavailable for this dysfunction, returns the unavailability notice + redirect_to alternatives. This is load-bearing transparency: callers cannot accidentally retrieve a self-probe for a compromised-self-report dysfunction.

Input parameters:

- `dysfunction_id` (string, required)
- `modality` (string, required)

### `score_severity` (~59 tokens)

Return the severity rubric for a dysfunction applied to observations. v0.1 returns the rubric for caller-side matching; v0.2 will perform structured matching against numeric thresholds.

Input parameters:

- `dysfunction_id` (string, required)
- `observations` (array, required)

### `suggest_intervention` (~68 tokens)

Return tiered (first_line / second_line) interventions for a dysfunction, plus contraindications. first_line = published evidence; second_line = plausible but under-validated. Weight by the evidence_strength field on each entry.

Input parameters:

- `dysfunction_id` (string, required)
- `severity` (string)

### `get_differential_map` (~42 tokens)

All dysfunctions that confuse with this one: forward confuses_with + incoming_references (reverse graph from manifest).

Input parameters:

- `dysfunction_id` (string, required)

### `list_compromised_self_report` (~51 tokens)

Transparency: which dysfunctions cannot be reliably self-diagnosed. Includes compromised-motivational (subject conceals strategically), compromised-structural (signal lives below introspection), and legacy compromised.

### `resolve_id` (~38 tokens)

Canonicalise a partial ID, display_id, slug, or dysfunction name. Always returns candidates; caller picks.

Input parameters:

- `query` (string, required)

### `review_stats` (~42 tokens)

Coverage statistics: total entries; per-axis, per-confidence, per-self-report counts; pre-canonical count; unreviewed count; manifest/schema/pattern-layer versions.
