## Facts

- Tool: `deleteRule`
- Server: Whistle (`7gugu/whistle-mcp`) — https://policylayer.com/tools/7gugu-whistle-mcp.md
- Homepage: https://github.com/7gugu/whistle-mcp
- Risk category: Destructive (Critical risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Hidden

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "deleteRule",
    "arguments": {}
  }
}
```

## Why deleteRule is rated Critical

Deleting rules from a Whistle proxy server removes configurations that may be critical to network request handling, filtering, or monitoring. This action is irreversible and could disrupt network traffic management if misused by an AI agent. The blast radius includes potential loss of important proxy configurations and inability to restore them without manual intervention.

From the tool's own definition: "Tool name 'deleteRule' and description '删除规则' (Chinese: 'delete rule') indicate irreversible deletion of proxy rules. Combined with sibling tools like deleteGroup, deleteValue, deleteValueGroup, this is clearly a destructive operation that cannot be undone."

## Use case

AI agents call deleteRule to permanently remove resources in Whistle, 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 Whistle:

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