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

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

## Why stop_emba_scan is rated High

Stopping an active scan is an Execute action that triggers an external operation (halting the EMBA firmware analysis engine). While not destructive of data or financial in nature, it interrupts a system operation whose continuation state depends on the tool's invocation. This could disrupt analysis workflows and has blast radius potential if invoked by an AI agent without user intent.

From the tool's own definition: "Tool name 'stop_emba_scan' indicates termination of an active firmware analysis scan process."

## Use case

AI agents invoke stop_emba_scan to trigger actions in EMBA-MCP. 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 EMBA-MCP:

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