What this server does
This MCP server proxies requests to a SNOMED CT terminology server (Snowstorm or Snowstorm Lite). It translates MCP tool calls into FHIR and Snowstorm API requests, returns the results, and does not store any data between requests.
Data collection
This server does not:
- Collect, store, or process personal data
- Use cookies or local storage
- Log query content to persistent storage
- Send data to any third party beyond the configured SNOMED CT backend
All requests are forwarded to the configured Snowstorm backend and responses are returned directly to the caller. No request or response content is retained after the response is delivered.
Per-session rate limiting
When per-session rate limiting is enabled in the server configuration, the server maintains an in-memory record of call timestamps per MCP session for the sole purpose of enforcing rate limits. This state contains no personally identifiable information, no query content, and no response data. It is held only in process memory and is automatically discarded when the session ends (via weak references) or the server process stops. No session state is persisted to disk or transmitted externally.
Backend data
Responses contain SNOMED CT terminology content (concept codes, descriptions, relationships) provided by the connected Snowstorm instance. SNOMED CT content is subject to the SNOMED International licensing terms.
Hosting
When deployed as a hosted connector, standard web server access logs (IP address, timestamp, request path) may be retained by the hosting infrastructure for operational purposes. These logs do not contain query parameters or request bodies.
