The server correctly loads API credentials from environment variables and logs sanitized versions. Input validation for tool arguments is performed using Zod schemas. All external API communication is via HTTPS. The `update_workout` tool performs a delete followed by a create, with a critical error path if the creation fails after deletion. Extensive logging to a debug file is implemented, which includes a preview of API responses. While credentials are sanitized, small full API response bodies might be logged for debugging, potentially exposing user data if the log file is not properly secured, although this is a common debug practice and not a direct vulnerability in data handling or authentication.
