open-notifications

THE RISK

High Risk

This tool triggers an external operation on a device (opening the notifications panel), which is a UI/system action with side effects. It doesn't read, write, or delete data, but it executes a device-level action that could expose sensitive notification content or enable further interactions. Classified as Execute due to triggering an external operation on the device.

From the tool's definition Open the notifications panel (Android only)

HOW TO CONTROL OPEN-NOTIFICATIONS

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "open-notifications": {
      "limits": [
        {
          "counter": "open-notifications_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

open-notifications 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 MCP Appium Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
