Why browser_network_stop needs a policy

This tool executes a command that modifies the runtime state of the browser (toggling network request logging off). While not destructive or financially risky, it performs an action with side effects on the browser's operational state rather than simply retrieving data.

From the tool's definition Tool named 'browser_network_stop' with description 'Stop logging network requests.' belongs to a browser automation server that controls Firefox/Chromium instances.

POLICY

How to control browser_network_stop

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

policy.json

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

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