The rule that runs capture_region_clipboard 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 capture_region_clipboard, this is the rule to start with:
capture_region_clipboard 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 Omarchy-MCP, apply this rule, and every capture_region_clipboard call is checked against it from then on.
