SNOMED CT Terminology
Claude connectorSearch, validate, and expand SNOMED CT concepts, directly from SNOMED International
SNOMED CT is the world's most comprehensive clinical terminology, used in electronic health records across more than 80 countries. This connector gives Claude direct access to it through SNOMED International's terminology server.
Use it to look up concepts by code or name, validate that a code exists and is active, test subsumption between concepts, navigate the hierarchy (ancestors, children, descendants), and expand value sets using Expression Constraint Language (ECL). It works across all SNOMED CT editions available on the connected backend, including the International, US and Australian editions.
Every tool is read-only, the connector never modifies terminology data. It runs as a stateless proxy to the configured Snowstorm instance, holding no query content or personal data between requests.
Built and maintained by SNOMED International, the owners of SNOMED CT.
