What this server can do
21 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
analyze_clinical_case(papers_limit, diseases_limit, case_description)- Caso clínico → doenças candidatas + literatura relevante em 1 chamada. Apenas informativo, nunca diagnóstico. Required: case_description.
explain_relation(query, hpo_ids, max_hops)- Raciocínio fundamentado sobre o grafo: dada uma pergunta (ex.: "por que o gene X se associa à doença Y?", "como a droga Z se relaciona a esta doença?"), retorna caminhos de evidência multi-hop (doença↔gene↔via↔droga↔fenótipo) com proveniência citável. Se não houver caminho no grafo, recusa — nunca inventa. Required: query.
find_active_trials(limit, orphaCode, in_brazil_only)- Trials ativos com filtro Brazil. Required: orphaCode.
find_communities(limit, orphaCode)- Comunidades FEBRARARAS por doença. Required: orphaCode.
find_diseases_by_phenotypes(limit, hpo_ids)- Match por IDs HPO. Use para diagnóstico diferencial. Required: hpo_ids.
find_papers_for_disease(limit, min_score, orphaCode)- Literatura relacionada a uma doença via embeddings (:SEMANTIC_MATCH, fallback vetorial). Required: orphaCode.
find_phenotypically_similar(limit, orphaCode)- Doenças com perfil de fenótipos HPO semelhante (simGIC pré-computado, explicável: nº de fenótipos em comum). Complementa find_similar_diseases (semântico). Required: orphaCode.
find_reference_centers(limit, state, orphaCode)- Centros por doença e/ou UF, com CNES.
find_similar_diseases(limit, orphaCode)- Vector similarity via embeddings SOTA. Required: orphaCode.
get_disease_detail(orphaCode)- Fenótipos HPO, genes, SUS, trials, descrição clínica em PT. Required: orphaCode.
get_evidence(orphaCode)- Cross-references de autoridade (Orphanet, MONDO, OMIM, MeSH, GARD, UMLS), status de verificação e PMIDs de uma doença. A base da regra "nunca inventar". Required: orphaCode.
get_graph_stats- Contagens e métricas do dataset.
get_hypotheses(orphaCode)- Candidatos a reposicionamento de fármacos gerados por associação de genes (guilt-by-association): drogas que tratam outras doenças que compartilham genes com esta. HIPÓTESES para investigação, NUNCA recomendações clínicas — cada uma rastreável (via gene X, da doença Y). Required: orphaCode.
get_literature_relations(orphaCode, predicate)- Relações tipadas extraídas da literatura biomédica (associate/treat/cause/inhibit/stimulate/prevent) entre a doença e genes/fármacos, com nº de publicações como proveniência. Filtrável por predicado. Required: orphaCode.
get_recent_updates(days, limit)- Doenças cujo gêmeo digital ganhou evidência nova (autoria, PubTator3, Open Targets, verificação) nos últimos N dias. Faça polling para acompanhar mudanças (substituto stateless de subscriptions).
get_research_log(orphaCode)- Registro cronológico do que o agente autônomo fez por esta doença: autoria, mineração de literatura, evidência genética, verificação, prospecção de fontes, recomputação de relações. Prova de que o gêmeo digital estuda a doença continuamente. Required: orphaCode.
get_schema- Node labels, relationship types e property keys do grafo. Use antes de cypher_query.
get_sus_coverage(orphaCode)- CEAF, SIGTAP, PNTN, nível de integração. Required: orphaCode.
search_diseases(limit, query, filter_has_sus_coverage, filter_has_active_trials)- Full-text search em 10.468 doenças raras. Suporta filtros SUS/trials. Required: query.
search_papers_semantic(limit, query, min_score)- Busca vetorial sobre 424k papers do PubMed. Use caso clínico, pergunta ou conjunto de sintomas. Required: query.
search_phenotypes(limit, query)- Lookup HPO em PT ou EN. Retorna IDs HP:. Required: query.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
| Signal | Value | What it measures | Window | Observed | Source |
|---|---|---|---|---|---|
| Latest published version | 0.2.0 | Latest version string the maintainer published to the registry. | as of fetch | Model Context Protocol | |

| First listed in the MCP Registry | 2026-05-21 | Date this server was first published to the official MCP Registry. Not a usage or quality measure. | point in time | Model Context Protocol | |
| mcp tools declared | 21 tools | Number of functions the server itself declared when asked to list them. This is what the server offers an agent, not a measure of how well any of them work. | as of probe | raras.org | |
