Raras tools (20)

write = sends, deletes, buys or posts
  • analyze_clinical_caseFree

    Caso clínico → doenças candidatas + literatura relevante em 1 chamada. Apenas informativo, nunca diagnóstico.

  • explain_relationFree

    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.

  • find_active_trialsFree

    Trials ativos com filtro Brazil.

  • find_diseases_by_phenotypesFree

    Match por IDs HPO. Use para diagnóstico diferencial.

  • find_papers_for_diseaseFree

    Literatura relacionada a uma doença via embeddings (:SEMANTIC_MATCH, fallback vetorial).

  • find_phenotypically_similarFree

    Doenças com perfil de fenótipos HPO semelhante (simGIC pré-computado, explicável: nº de fenótipos em comum). Complementa find_similar_diseases (semântico).

  • find_reference_centersFree

    Centros por doença e/ou UF, com CNES.

  • find_similar_diseasesFree

    Vector similarity via embeddings SOTA.

  • get_disease_detailFree

    Fenótipos HPO, genes, SUS, trials, descrição clínica em PT.

  • get_evidenceFree

    Cross-references de autoridade (Orphanet, MONDO, OMIM, MeSH, GARD, UMLS), status de verificação e PMIDs de uma doença. A base da regra "nunca inventar".

  • get_graph_statsFree

    Contagens e métricas do dataset.

  • get_hypothesesFree

    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).

  • get_literature_relationsFree

    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.

  • get_recent_updatesFree

    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_logFree

    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.

  • get_schemaFree

    Node labels, relationship types e property keys do grafo. Use antes de cypher_query.

  • get_sus_coverageFree

    CEAF, SIGTAP, PNTN, nível de integração.

  • search_diseasesFree

    Full-text search em 10.468 doenças raras. Suporta filtros SUS/trials.

  • search_papers_semanticFree

    Busca vetorial sobre 424k papers do PubMed. Use caso clínico, pergunta ou conjunto de sintomas.

  • search_phenotypesFree

    Lookup HPO em PT-BR (encoder Araras-HPO-Brasil + léxico leigo) ou EN (vocabulário HPO). Retorna IDs HP: com estado de asserção: termo NEGADO ("nunca desmaiei") NÃO vira fenótipo. Outros idiomas não são cobertos. Limite de taxa: use poucas chamadas por minuto (429 = espere).

Raras Disease Twin — MCP Server

Brazilian rare-disease knowledge graph (10,468 diseases) exposed via the Model Context Protocol (MCP). Each disease is an addressable Disease Twin (disease://{orphaCode}): genes, HPO phenotypes, SUS coverage, clinical trials, literature-mined treatments, repurposing hypotheses, and grounded multi-hop reasoning — PT-BR first, source-grounded, never diagnoses.
