Security Notes
The server is explicitly designed to be 'authless' for demonstration purposes. While the arithmetic tools themselves use Zod for input validation (mitigating input injection for numeric inputs), the absence of any authentication mechanism means anyone with the URL can access and invoke the calculator functions. This is a critical security vulnerability for any non-public facing or sensitive application. No hardcoded secrets were found in the provided code snippets. Use with caution and only for its intended demo purpose.
