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

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

## Why qt_batch is rated High

The 'batch' suffix strongly implies executing multiple operations together. Given the server context (interacting with PySide6 desktop apps, sibling tools that click, type, invoke slots, press keys), a batch tool likely executes a sequence of such actions. This places it in the Execute category with potentially high blast radius since batching can chain many UI interactions.

From the tool's own definition: "Tool name 'qt_batch' on a server designed to 'perform actions like clicking buttons or typing text'; description is empty and uninformative."

## Use case

AI agents invoke qt_batch 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_batch": {
      "limits": [
        {
          "counter": "qt_batch_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`
