Environment / auth

WHO_CLIENT_ID
WHO ICD-11 API Client ID. Required only for ICD-11 tools (5 tools); the server starts without it and other terminologies (LOINC, RxNorm, MeSH, ATC, CID-10) work unauthenticated. Get credentials at https://icd.who.int/icdapi.
WHO_CLIENT_SECRET
secret
WHO ICD-11 API Client Secret. Required only for ICD-11 tools.
WHO_ICD11_RELEASE_ID
ICD-11 release to query (e.g. 2024-01, 2025-01). Optional; defaults to 2024-01.
ENABLE_SNOMED_TOOLS
Set to 'true' to register the 6 SNOMED-dependent tools (snomed_search, snomed_concept, snomed_hierarchy, snomed_descriptions, snomed_ecl, plus map_snomed_to_icd10). Disabled by default because the historical public IHTSDO Snowstorm endpoint was retired (HTTP 410 Gone). Requires SNOMED_BASE_URL pointing at a working self-hosted Snowstorm.
SNOMED_BASE_URL
Base URL of a self-hosted Snowstorm instance (e.g. https://my-snowstorm.example.com/snowstorm/snomed-ct). Required only when ENABLE_SNOMED_TOOLS is true.
SNOMED_LANGUAGE
Accept-Language tag(s) for SNOMED responses (e.g. pt, pt-BR, es). Optional; defaults to 'en'. Composite values with q-weights depend on the upstream Snowstorm instance.
LOG_LEVEL
pino log level (debug, info, warn, error, fatal). Optional; defaults to 'info'. Logs go to stderr only — never stdout (which is the MCP stdio transport).
