Why click_and_snapshot needs a policy

The tool performs a browser click action on an arbitrary UI element, which triggers real-world side effects (navigation, dialog submission, form submission, etc.) whose consequences depend entirely on what element is clicked. This is an Execute-category action — it drives external browser operations.

From the tool's definition 'Click element by ref + wait + return snapshot. Perfect for buttons that trigger navigation/dialog.'

POLICY

How to control click_and_snapshot

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_and_snapshot:

policy.json

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

click_and_snapshot 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.
