RECOMMENDED RULE

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

theme_bg_next Rate-limited

theme_bg_next 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.

          "max": 10,

        }
      ]
    }
  }
}

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