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

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

## Why focus_window is rated High

This tool triggers an external window management operation on the Windows system — activating/focusing a specific application window. This is an execution action that interacts with the OS UI layer, not merely reading data. Misuse could allow an AI to bring specific windows to focus as part of a larger automated attack chain (e.g., focusing a credential dialog before automated input).

From the tool's own definition: "Focus on a specific window by title (partial match)"

## Use case

AI agents invoke focus_window to trigger actions in Mcp Windows. 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 Mcp Windows:

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