The server's default Access-Control-Allow-Origin: * is overly permissive for production; it should be configured to specific allowed origins. The multi-tenant example explicitly uses *simulated* token validation; a real deployment requires robust external authentication. Error messages from tool execution could potentially leak verbose internal details depending on the underlying error, which is a minor concern. Hardcoded default API key in the OpenAI example is acceptable for development but requires proper environment variable configuration in production. The core library otherwise uses standard secure Go practices.
