Icd Mcp

stayce/icd-mcp-cloudflare

Connects directly to the WHO ICD API to give your assistant full access to both ICD-10 and ICD-11 classification systems. The twelve exposed actions cover everything from simple code lookups and validation to autocode, which converts free-text clinical descriptions into diagnosis codes using WHO's own matching engine. You can browse the hierarchy, search by keyword, trace code lineage, and pull coding rules without leaving the conversation. Defaults to ICD-11 but switches to ICD-10 with a version flag. Runs on Cloudflare Workers for global low-latency responses. Useful when building clinical tooling, assisting medical coders, or working with health data that needs proper diagnosis code mapping.
