Why open_notification_center needs a policy

This tool triggers a UI gesture (swipe) on the virtual iOS device to open the Notification Center. It executes an input/navigation action on an external system (the virtual machine), consistent with the Execute category. Blast radius is low as it only opens a system panel and doesn't modify or delete data.

POLICY

How to control open_notification_center

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

policy.json

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

open_notification_center 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 Vphone — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
