WHAT IT DOES

What browser_check does on Termux Browser Pilot

AI agents invoke browser_check 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_check is rated High

This tool performs an interactive browser action (checking/unchecking form controls) in a real browser. It's not merely reading data, nor is it creating/modifying persistent data in a reversible write sense — it executes a UI interaction that can trigger form submissions, enable/disable features, or change application state depending on the target element.

From the tool's definition 'Check, uncheck, or toggle a checkbox or radio button' — triggers browser UI interaction/action on a live browser automation session

RECOMMENDED RULE

The rule that runs browser_check 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_check, this is the rule to start with:

browser_check Rate-limited

browser_check 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.
