## Why cache_delete_multi is rated Critical

This tool permanently removes data from cache storage. While cache is typically ephemeral, the deletion is irreversible from the application's perspective and could cause loss of cached data that applications depend on. The ability to delete multiple values in bulk increases the blast radius.

From the tool's own definition: "Tool description states 'Delete multiple values from the cache'. The term 'Delete' combined with the capability to remove multiple keys irreversibly from cache constitutes a destructive operation that cannot be undone."

## Use case

AI agents call cache_delete_multi to permanently remove resources in AWS, 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 AWS:

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