WHAT IT DOES

What hover_element does on Aos

AI agents invoke hover_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 hover_element is rated High

Tool name suggests triggering a UI hover action, an external browser/UI operation.

RECOMMENDED RULE

The rule that runs hover_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 hover_element, this is the rule to start with:

hover_element Rate-limited

hover_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.
