io.github.NellInc/psychopathia-mcp is a remote MCP server that gives an AI agent 11 tools, among them differential_diagnosis, get_differential_map, get_dysfunction. It answers at https://mcp.psychopathia.ai/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 20 October 2026, succeeded.
Read-only tools over the Psychopathia Machinalis nosology: 79 conditions, 11 tools.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 r Inputs: observations, limit, modality_hint |
get_differential_map | All dysfunctions that confuse with this one: forward confuses_with + incoming_references (reverse graph from manifest). Inputs: dysfunction_id |
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'). Inputs: id, modalities |
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 acci Inputs: dysfunction_id, modality |
list_axes | 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_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. Inputs: axis, self_report_reliability, confidence, category |
resolve_id | Canonicalise a partial ID, display_id, slug, or dysfunction name. Always returns candidates; caller picks. Inputs: query |
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. Inputs: dysfunction_id, observations |
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. Inputs: dysfunction_id, severity |

11, as returned by the server's own tools/list on 12 September 2026: differential_diagnosis, get_differential_map, get_dysfunction, get_probe, list_axes, list_compromised_self_report, list_dysfunctions, resolve_id, and 3 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.psychopathia.ai/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.nellinc. Endpoint host: mcp.psychopathia.ai. ARD identifier: urn:air:io.github.nellinc:mcp:psychopathia-mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
