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

```json
{
  "jsonrpc": "2.0",

    "name": "qt_trigger_action",
    "arguments": {}

## Why qt_trigger_action is rated High

This tool invokes UI actions on a desktop application, which can trigger application-defined behavior with unpredictable side effects. Without knowing which specific action is triggered, an AI agent could inadvertently perform destructive or financial operations (e.g., clicking 'Delete All' or 'Send Payment' buttons).

From the tool's own definition: "Tool name 'qt_trigger_action' indicates it performs action invocation on PySide6 UI elements. Sibling tools include 'qt_click', 'qt_key_press', and 'qt_invoke_slot', all of which execute user interactions."

## Use case

AI agents invoke qt_trigger_action to trigger actions in Qt. 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 Qt:

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