Why iphone_operate_app_launch needs a policy

This tool executes a command on a mobile device to launch applications. While not destructive or financial on its own, launching apps is an Execute-category action because it triggers system-level operations with side effects that depend entirely on the argument (which app to launch).

From the tool's definition Tool description states 'Launch app' and is part of a suite enabling 'control apps' and 'perform touch operations via natural language commands.' Launching an app is an executable action that triggers external operations on the iPhone device whose effects…

POLICY

How to control iphone_operate_app_launch

PolicyLayer is an MCP gateway — it sits between your AI agents and iPhone MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for iphone_operate_app_launch:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "iphone_operate_app_launch": {
      "limits": [
        {
          "counter": "iphone_operate_app_launch_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

iphone_operate_app_launch stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register iPhone MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
