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

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

## Why bazel_ios_device_stop_app is rated High

This tool executes an external command that terminates an application process on a physical device. While it is not destructive (the app continues to exist and can be relaunched) and not permanent data deletion, it is an Execute action because it actively triggers an operation whose side effects depend on the device state and app identifier.

From the tool's own definition: "Tool name includes 'stop_app' and description states 'Terminate a running app on a connected physical iOS device' — this is a direct action that affects running processes on a device."

## Use case

AI agents invoke bazel_ios_device_stop_app to trigger actions in XcodeBazelMCP. 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 XcodeBazelMCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "bazel_ios_device_stop_app": {
      "limits": [
        {

          "window": "minute",
          "max": 10,
