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

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

## Why destroy_vm is rated Critical

This tool irreversibly removes a VM instance, which cannot be undone without restoration from backups. The action has significant blast radius in a cyber range environment—a compromised AI agent could destroy critical test infrastructure, disrupt research sessions, and cause loss of experimental data. While not financial, this is more severe than Execute or Write operations.

From the tool's own definition: "The tool name 'destroy_vm' and description 'Destroy a specific VM' use explicit destructive terminology. The verb 'destroy' indicates irreversible deletion or termination of a virtual machine."

## Use case

AI agents call destroy_vm to permanently remove resources in Ludus FastMCP, 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 Ludus FastMCP:

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