Environment variables

Defined in the server's official registry manifest. Required secrets are shown as <YOUR_…> placeholders in the configs above.

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/icd
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 2026-01.
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).
