Why browser_geo_clear needs a policy

This tool removes a previously set geolocation override and restores default browser behavior. It modifies browser state (removes a configuration), which is a reversible write-like action. It does not delete persistent data, execute code, or have financial implications. Severity is low as it only affects browser geolocation settings.

How to control browser_geo_clear

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_geo_clear:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_geo_clear": {
      "limits": [
        {
          "counter": "browser_geo_clear_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

browser_geo_clear stays usable, but capped — an agent stuck in a loop can't make hundreds of changes 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.
