## Trust

- hygiene: 100
- liveness: 99
- freshness: 85
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-97% ~updated-46d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 89/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 12 of 12 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,864 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 12 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: 83 (weight 15)

- pass `deps.known_vulns`: no known advisory in 30 resolved packages
- warn `deps.mcp_sdk_version`: mcp 2.1.1 has 1 known advisory of lower severity or without a fix (GHSA-84m7-p3x7-pcfv)
- pass `deps.resolvable`: psychopathia-mcp@0.1.0a7 resolved: 30 packages

- tools: 12, about 1,864 tokens to load them all
- tool set hash: 1cd309a440c423a7096d066ff048c6fb
- tools last changed: 2026-09-30T15:23:54.541Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.NellInc/psychopathia-mcp.svg)](https://protogrid.dev/servers/io.github.NellInc/psychopathia-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-30 `render_pattern_review` added
  - 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.
- 2026-09-30 `review_stats` changed (annotations)
- 2026-09-30 `resolve_id` changed (inputSchema, annotations)
- 2026-09-30 `list_compromised_self_report` changed (annotations)
- 2026-09-30 `get_differential_map` changed (inputSchema, annotations)
- 2026-09-30 `suggest_intervention` changed (inputSchema, annotations)
- 2026-09-30 `score_severity` changed (inputSchema, annotations)

## Packages

- pypi psychopathia-mcp@0.1.0a7

## Tools (12)

- `differential_diagnosis`: 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.
- `get_differential_map`: All dysfunctions that confuse with this one: forward confuses_with + incoming_references (reverse graph from manifest).
- `get_dysfunction`: 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`: 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`: 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`: 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`: Filtered list of dysfunctions. Filter by axis, self_report reliability, confidence, or category. Every entry carries its reliability and review signals.
- `render_pattern_review`: 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.
- `resolve_id`: Canonicalise a partial ID, display_id, slug, or dysfunction name. Always returns candidates; caller picks.
- `review_stats`: Coverage statistics: total entries; per-axis, per-confidence, per-self-report counts; pre-canonical count; unreviewed count; manifest/schema/pattern-layer versions.
- `score_severity`: 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`: 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.
