Tools & capabilities

Medical Terminologies MCP tools 33

  • icd11_searchSearch for medical conditions, diseases, and health problems in ICD-11 (International Classification of Diseases, 11th Revision). Use this tool to: - Find ICD-11 codes for diagnoses - Search for diseases by name or keyword - Look up conditions in multiple languages Set `language` for WHO's official translations — e.g. `language: "pt"` searches and returns the official Portuguese (pt-BR) ICD-11 labels. Never machine-translated. Returns matching entities with codes, titles, and relevance scores.
  • icd11_lookupGet detailed information about a specific ICD-11 entity by code or URI. Use this tool to: - Get the full definition of a disease - Retrieve coding notes and exclusions - Get the official title and synonyms Provide either an ICD-11 code (e.g., "BA00") or a full foundation URI. Set `language` for WHO's official translations (e.g. `language: "pt"` for official Portuguese).
  • icd11_hierarchyNavigate the ICD-11 hierarchy to find parent or child entities. Use this tool to: - Find broader categories (parents) of a condition - Find specific subtypes (children) of a condition - Understand the classification structure Name the entity by `code` (a leaf code like "5A11", or a block range like "5A10-5A2Y" — blocks come back from 'parents' with an empty code and a code_range) or by `uri` (the URI any previous answer returned). Direction 'parents' returns ancestor categories, 'children' returns subcategories. ICD-10 codes (like "E11") are not ICD-11 codes: convert them first with map_icd10_to_icd11.
  • icd11_chaptersList all ICD-11 chapters (top-level categories). Use this tool to: - Get an overview of ICD-11 structure - Find which chapter covers a body system or condition type - Navigate to specific disease categories ICD-11 has 28 chapters covering all areas of medicine.
  • icd11_postcoordinationGet postcoordination information for an ICD-11 code. Use this tool to: - Find available axes for building composite codes - Check required vs optional postcoordination - Understand code extension possibilities Postcoordination allows adding severity, laterality, anatomy, etc.
  • loinc_searchSearch for laboratory tests, clinical observations, and measurements in LOINC (Logical Observation Identifiers Names and Codes). Use this tool to: - Find LOINC codes for lab tests (e.g., "glucose", "hemoglobin") - Search for clinical measurements and vital signs - Look up diagnostic observations Returns matching LOINC codes with names, components, and properties.
  • loinc_detailsGet detailed information about a specific LOINC code. Use this tool to: - Get the full name and description of a LOINC code - Find the component, property, timing, and system - Check the scale type and method Provide a LOINC number in format "XXXXX-X" (e.g., "2339-0" for Glucose).
  • loinc_answersGet the list of valid answers for a LOINC questionnaire item. Use this tool to: - Find valid response options for survey questions - Get answer codes for data entry validation - Look up standardized answer lists Only applicable to LOINC codes that represent questions with defined answer sets.
  • loinc_panelsGet the structure of a LOINC panel or form. Use this tool to: - See all tests included in a panel (e.g., CBC, metabolic panel) - Get the structure of assessment forms - Find related observations grouped together Returns the list of LOINC codes that make up the panel.
  • rxnorm_searchSearch for drugs in RxNorm (Normalized names for clinical drugs). Use this tool to: - Find drug concepts by brand or generic name - Look up medications for prescribing - Search for drug formulations Returns matching drugs with RxCUI identifiers, names, and term types.
  • rxnorm_conceptGet detailed information about a specific RxNorm concept by RxCUI. Use this tool to: - Get the full name and synonyms for a drug - Check the concept status (active, remapped, etc.) - View related concepts (ingredients, brands, forms) Provide an RxCUI (RxNorm Concept Unique Identifier) like "161".
  • rxnorm_ingredientsGet active ingredients for a drug by RxCUI. Use this tool to: - Find the active ingredients in a medication - Check for single vs. multiple ingredient products - Identify the generic components of brand drugs Returns ingredient RxCUIs and names.
