Why browser_mock_clear needs a policy

This tool irreversibly removes/deletes browser response mocks. Deletion of mocks cannot be undone and falls under the Destructive category. Severity is medium since the blast radius is limited to browser mock configurations rather than persistent user data.

POLICY

How to control browser_mock_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_mock_clear:

policy.json

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

browser_mock_clear 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.
