long_click

THE RISK

High Risk

This tool triggers UI interactions on an Android device, executing touch/press actions that can open context menus, initiate drags, or trigger long-press behaviors. The effects depend entirely on the target element and could cause unintended actions (e.g., deleting items via context menu, rearranging UI elements).

From the tool's definition 'Perform a long click (press and hold) on a UI element. Useful for context menus, drag operations, or long press actions.'

HOW TO CONTROL LONG_CLICK

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

policy.json

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

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