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

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

## Why scale_virtual_machine is rated High

Scaling VM CPU/memory is an Execute action because it triggers infrastructure operations whose effects depend on the scaling parameters provided. While not permanently destructive (reversible via scaling down), it directly modifies running systems and can cause service disruptions, performance impacts, or cascading failures.

From the tool's own definition: "Tool performs 'scale virtual machine CPU/memory' - this is a real-time operational change to running infrastructure that modifies compute resources and triggers external effects on the virtual machine."

## Use case

AI agents invoke scale_virtual_machine to trigger actions in CloudStack MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches CloudStack MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "scale_virtual_machine": {
      "limits": [
        {
          "counter": "scale_virtual_machine_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
