Security Notes

The server uses standard security middleware (helmet, cors, express-rate-limit) for common web vulnerabilities and rate limiting. It acts as an API gateway, proxying requests to an external API. There are no 'eval' or direct shell command executions observed. Sensitive URLs (`PLUTOCALC_API_BASE_URL`) are configurable via environment variables. Input validation against the `inputSchema` defined in `tools` metadata is not explicitly performed by the gateway before proxying requests; however, arguments are stringified as JSON to the backend API, which helps mitigate direct injection in the gateway itself. The ultimate security depends on the Plutocalc Designer API's own input handling.
