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

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

## Why bazel_ios_stop_app is rated High

This tool executes a command with side effects on a running system (simulator). While termination is reversible (the app can be restarted), it is an active operation that changes system state and could disrupt development workflows or testing. It does not permanently delete data (Destructive) nor retrieve it (Read), nor does it create/modify versioned data (Write).

From the tool's own definition: "Tool performs 'Terminate a running app' — an action that triggers external operation (app termination on simulator) whose effects depend on the bundle identifier argument."

## Use case

AI agents invoke bazel_ios_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_stop_app": {
      "limits": [
        {
          "counter": "bazel_ios_stop_app_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
