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

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

## Why deleteValueGroup is rated Critical

This tool permanently removes a values group without the ability to undo the operation. While not financial data, the deletion of proxy configuration groups could disrupt network monitoring and management workflows. Classified as Destructive rather than Write because the action is irreversible; users cannot recover deleted groups without manual reconfiguration.

From the tool's own definition: "Tool name 'deleteValueGroup' combined with description '删除值分组' (Chinese: 'delete values group') indicates irreversible deletion of a grouped collection of values in the Whistle proxy configuration."

## Use case

AI agents call deleteValueGroup 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
{
