Security Notes

The server is explicitly designed to operate "Without Auth" as stated in the README, making it publicly accessible. While intentional for a demo/playground integration, this means the endpoint should only expose non-sensitive functionality. The provided tools (add, calculate) perform simple arithmetic and use Zod for robust input validation, mitigating common injection risks for these specific operations. No malicious patterns or 'eval' usage are observed in the source code. The primary security consideration is to avoid deploying this 'authless' setup for any sensitive production use cases.
