WHAT IT DOES

What patch_fixture does on Aos

AI agents invoke patch_fixture 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 patch_fixture is rated High

Executes a command-line operation on grandMA3 lighting console, affecting fixture configuration.

RECOMMENDED RULE

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

patch_fixture Rate-limited

patch_fixture 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 Aos, apply this rule, and every patch_fixture call is checked against it from then on.
