What browser_tab_goto does on Termux Browser Pilot

AI agents invoke browser_tab_goto to trigger actions in Termux Browser Pilot. 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.

High Risk

Why browser_tab_goto needs a policy

This tool triggers a browser action (switching tabs) in an automated browser environment. It causes an external operation in the browser session whose effects depend on the argument (tab index). While switching tabs is not inherently destructive or financial, it constitutes a browser automation action that could expose sensitive content in other tabs or facilitate further actions, placing it in the Execute category.

How to control browser_tab_goto

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_tab_goto:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_tab_goto": {
      "limits": [
        {
          "counter": "browser_tab_goto_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

browser_tab_goto 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.

  1. Create a free account and register Termux Browser Pilot — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
