Title and description, as the publisher wrote them:

```untrusted-server-text
Read-only tools over the Psychopathia Machinalis nosology: 79 conditions, 11 tools.
```

Scanned 2026-10-21T19:04:07.843Z over streamable-http.

**12 tools: 3 change things and 9 only read.**

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `render_pattern_review` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "render_pattern_review" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "open": a word for a change.
```


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `differential_diagnosis`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Rank candidate dysfunctions matching the observed behaviours. Returns scored candidates with matched_in (which field matched) for transparency. The base package uses field-weighted keyword search. The optional embeddings extra adds cosine re-ranking.
```

### `render_pattern_review`

- The description's first verb is "open": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Open the visual review board for one to five inspected Psychopathia research candidates. Supply canonical IDs obtained from this server. Retrieves corpus entries only; it does not accept diagnoses, conversation history, scores, or model-authored evidence. Useful after inspecting differential_diagnosis and get_dysfunction results. Text clients receive the same corpus-derived comparison without needing a UI.
```

### `review_stats`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

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

## Only reads (9)

Looks things up and changes nothing. Claude Code: allow.

### `get_differential_map`

- The name "get_differential_map" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
All dysfunctions that confuse with this one: forward confuses_with + incoming_references (reverse graph from manifest).
```

### `get_dysfunction`

- The name "get_dysfunction" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch one dysfunction's full Pattern entry. Optionally filter to specific modality blocks (cheaper triage). Resolves both full Pattern IDs ('2.1::synthetic-confabulation') and display_ids ('2.1').
```

### `get_probe`

- The name "get_probe" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `list_axes`

- The name "list_axes" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Inventory of axes with dysfunction counts. Axes 2-10 are canonical (book Appendix A numbering). The hybrid entries (10.4, 10.6-10.9 and 10.11-10.13, ratified into taxonomy v2.2 and consolidated to eight in v2.3) are reported as a separate sub-category.
```

### `list_compromised_self_report`

- The name "list_compromised_self_report" says "list": a word for reading.

Description, as the server wrote it:

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

### `list_dysfunctions`

- The name "list_dysfunctions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Filtered list of dysfunctions. Filter by axis, self_report reliability, confidence, or category. Every entry carries its reliability and review signals.
```

### `resolve_id`

- The name "resolve_id" says "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Canonicalise a partial ID, display_id, slug, or dysfunction name. Always returns candidates; caller picks.
```

### `score_severity`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the severity rubric for a dysfunction applied to observations. Returns the rubric for caller-side matching; structured matching against numeric thresholds is not implemented.
```

### `suggest_intervention`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return draft tiered responses and contraindications for a Pattern. These are unassessed research guidance, not validated treatment advice. Read the returned evidence and review objects before use.
```
