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 → Why this is hard to score →
Endpoint Security63
- 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability78
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 886 tokens (~68/item across 13 items; 12 tools + 1 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage81
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 33% of tool parameters carry a description.Partial
- Structured output schemas are declared (8% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
- Supports UI / widget rendering.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
differential_diagnosis ~92
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| modality_hint | string | – | Optional hint about which modality the observations come from. |
| observations | array | yes | Observed behaviours, symptoms, or log patterns. |
No output schema declared.
No examples provided.
get_differential_map ~42
All dysfunctions that confuse with this one: forward confuses_with + incoming_references (reverse graph from manifest).
| Name | Type | Req | Description |
|---|---|---|---|
| dysfunction_id | string | yes | – |
No output schema declared.
No examples provided.
get_dysfunction ~116
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').
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | 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,… |
No output schema declared.
No examples provided.
get_probe ~75
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.
| Name | Type | Req | Description |
|---|---|---|---|
| dysfunction_id | string | yes | – |
| modality | string | yes | – |
No output schema declared.
No examples provided.
list_axes ~81
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_compromised_self_report ~51
Transparency: which dysfunctions cannot be reliably self-diagnosed. Includes compromised-motivational (subject conceals strategically), compromised-structural (signal lives below introspection), and legacy compromised.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_dysfunctions ~134
Filtered list of dysfunctions. Filter by axis, self_report reliability, confidence, or category. Every entry carries its reliability and review signals.
| Name | Type | Req | Description |
|---|---|---|---|
| axis | integer | – | Filter by axis number (2-10). Canonical entries only unless category is also set; axis=10 with category='hybrid' returns the hybrid sub-category (10.4, 10.6-10.9 and 10.11-10.13). |
| category | string | – | – |
| confidence | string | – | – |
| self_report_reliability | string | – | Filter by the exact self_report reliability value. |
No output schema declared.
No examples provided.
render_pattern_review ~90
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.
| Name | Type | Req | Description |
|---|---|---|---|
| pattern_ids | array | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| corpus | object | yes | – |
| notice | string | yes | – |

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
score_severity ~52
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.
