mcp_server

The server implements robust local filesystem sandboxing and command allowlisting (using `shell: false` with `spawn` for commands), which is critical for preventing directory traversal and arbitrary code execution locally. However, the `cloud_storage` and `image_process` tools contain 'placeholder' or 'simplified' implementations that lack proper SDKs and secure authentication mechanisms (e.g., using basic auth for cloud storage instead of proper Signature V4 signing), potentially exposing credentials or leading to insecure interactions with external services if used without installing recommended libraries or implementing robust security. The claim of 'military-grade sandboxing' for cloud storage is not met by the current simplified code. The `send_notification` tool's webhook functionality also relies on basic HTTP requests without inherent advanced security features. Therefore, while local operations are well-secured, interactions with external services require careful user configuration and potentially additional secure library installations.
