WHAT IT DOES

What wait_for_element does on Aos

AI agents invoke wait_for_element to trigger actions in Aos. 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 wait_for_element is rated High

This tool triggers an external operation (browser state monitoring/waiting) whose effects depend on arguments (which element, timeout conditions). It falls under Execute rather than Read because it actively participates in browser automation workflows that can have side effects through subsequent actions.

From the tool's definition Tool name 'wait_for_element' combined with sibling tools like 'click_element', 'close_browser', and 'check_droplet_responsiveness' indicates this is part of a browser automation/interaction suite.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs wait_for_element safely

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

wait_for_element Rate-limited

wait_for_element 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Aos, apply this rule, and every wait_for_element call is checked against it from then on.
