WHAT IT DOES

What doubleClick does on Chrome MCP Server

AI agents invoke doubleClick to trigger actions in Chrome MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

Why doubleClick needs a policy

This tool triggers browser interactions (double-click) at arbitrary coordinates, which can activate UI elements, open files, submit forms, or trigger application-specific behaviors depending on what's on the page. As part of a browser automation suite that controls Chrome, misuse could activate unintended actions across any web application the browser is navigating.

From the tool's definition Double click at specific x,y coordinates in the browser window... Useful for text selection or other double-click specific actions.

POLICY

How to control doubleClick

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

policy.json

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

doubleClick 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 Chrome 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.
