WHAT IT DOES

What window_fullscreen does on Omarchy-MCP

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs window_fullscreen safely

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

window_fullscreen Rate-limited

window_fullscreen 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.
