Why click_turnstile needs a policy

This tool executes a browser action (clicking a Cloudflare Turnstile CAPTCHA) to bypass bot-detection systems. It is an active browser interaction that triggers external effects (completing a challenge, gaining access to protected resources). The bypass of security controls raises the severity, as misuse could enable unauthorized access to protected sites at scale.

From the tool's definition "Auto-find and click Cloudflare Turnstile checkbox" — triggers an automated browser action to interact with and bypass a bot-detection challenge

POLICY

How to control click_turnstile

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

policy.json

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

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