THE RISK

Why browser_profile_delete needs a policy

Deleting a browser profile is an irreversible action that destroys saved settings, cookies, history, passwords, and other persistent user data. This falls into the Destructive category (not merely Write) because the effect cannot be undone. The severity is high because an agent misusing this tool could permanently erase critical authentication credentials or user configurations.

From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete a saved browser profile' — irreversible removal of stored data.

POLICY

How to control browser_profile_delete

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_profile_delete:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "browser_profile_delete"
  ]
}

browser_profile_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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.
