WHAT IT DOES

What browser_form_fill does on Termux Browser Pilot

AI agents invoke browser_form_fill 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_form_fill is rated High

The tool name 'browser_form_fill' strongly implies it fills in form fields in a browser, which constitutes a browser action/execution (interacting with web page elements). This could trigger form submissions, input credentials, or interact with financial/destructive web forms. The description is empty, lowering confidence.

From the tool's definition Tool name: browser_form_fill; server description mentions real browser automation with Firefox or Chromium

browser_form_fill 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.
