The server correctly uses a whitelist (`tools` object) to dispatch tool calls, preventing arbitrary code execution. It handles JSON parsing and stringifying, which are standard and generally safe. There are no obvious hardcoded secrets or direct 'eval' usage. Data is stored in-memory, which is not a security risk but means data persistence is not handled. Text input for todos is stored directly, but the React frontend automatically escapes content, mitigating client-side XSS if it were used in a UI. For a demo, the security practices are robust.
