WHAT IT DOES

What browser_mock_set does on Termux Browser Pilot

AI agents invoke browser_mock_set 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.

RISK

Why browser_mock_set is rated High

This tool intercepts and overrides network requests in the browser, injecting fake responses for fetch/XHR calls. This constitutes an active browser-level operation that manipulates the browser's network behavior — it's not merely reading data or writing persistent data, but executing a runtime interception that can alter application behavior, potentially deceive the user or application, and affect security controls.

RECOMMENDED RULE

The rule that runs browser_mock_set safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Termux Browser Pilot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For browser_mock_set, this is the rule to start with:

browser_mock_set Rate-limited

browser_mock_set 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.
