## Why delete_backup is rated Critical

This tool irreversibly deletes backup data, which cannot be undone. Deletion of backups is a destructive operation with significant blast radius—an AI agent misusing this could permanently lose recovery points for Valkey instances. This is more severe than Write (reversible modifications) and categorizes as Destructive.

From the tool's own definition: "Tool name is 'delete_backup' and description states 'Delete a Memorystore for Valkey backup.' The verb 'Delete' indicates irreversible removal of data."

## Use case

AI agents call delete_backup to permanently remove resources in Mcp, 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 Mcp:

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