WHAT IT DOES

What browser_attr_set does on Termux Browser Pilot

AI agents invoke browser_attr_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_attr_set is rated High

Setting an attribute on a DOM element modifies the live state of a webpage in a browser session. This is a write-like action that can trigger side effects (e.g., changing href, src, event handlers, or form actions), potentially enabling injection or manipulation of browser behavior. It goes beyond simple data writes because it directly manipulates browser/DOM state and can influence subsequent execution.

RECOMMENDED RULE

The rule that runs browser_attr_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_attr_set, this is the rule to start with:

browser_attr_set Rate-limited

browser_attr_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.
