click_image_if_found

THE RISK

High Risk

This tool performs a screen-based GUI automation action by locating an image and clicking it. Clicking UI elements can trigger arbitrary application behavior (buttons, links, dialogs, confirmations), making it an Execute-category tool. The blast radius is high because a misused click could confirm destructive dialogs, submit forms, or trigger unintended system operations.

From the tool's definition 'Find and click an image on the screen' — triggers a UI interaction (mouse click) on the Windows system based on visual matching

HOW TO CONTROL CLICK_IMAGE_IF_FOUND

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

policy.json

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

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