Safety Assessment

This server is relatively safe for read-only operations and simple recipe execution. However, caution should be exercised when using batch processing or exposing the CyberChef API URL to untrusted environments. Ensure the CyberChef API itself is properly secured.

Recipe execution is sandboxed within CyberChef's environment.
No direct filesystem access.
Access is controlled via the CyberChef API URL.
Read-only operations available for exploring CyberChef capabilities.

Maliciously crafted recipes could potentially cause resource exhaustion.
Exposure of the CyberChef API URL could lead to unauthorized access.
Batch processing could amplify the impact of a flawed recipe.
Lack of built-in RBAC within the MCP server itself.
