## Why file_delete is rated Critical

This tool destroys data irreversibly by permanently deleting files. Even though it operates on a single file (limiting blast radius compared to bulk deletion), the permanent nature and inability to recover the deleted file places it in the Destructive category, which ranks higher than Write, Execute, or Read.

From the tool's own definition: "Tool name is 'file_delete' with description 'Permanently delete one file an app has stored.' The use of 'Permanently delete' indicates an irreversible action that cannot be undone."

## Use case

AI agents call file_delete to permanently remove resources in Open Mcp Apps, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Open Mcp Apps:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "file_delete"
  ]
}
```
