THE RISK

Why console_start needs a policy

This tool captures/reads console messages from browser tabs. It is a monitoring/read operation that collects output but does not modify state, execute code, or cause destructive effects. The blast radius is low as it only observes console output.

From the tool's definition Start capturing console messages from all tabs

POLICY

How to control console_start

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 console_start:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "console_start": {}
  }
}

console_start is read-only, so it stays allowed — but 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.
