RECOMMENDED RULE

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

set_window_foreground Rate-limited

set_window_foreground 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.
