Attacks that exploit this kind of access
The rule that runs add_audio_bus safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_audio_bus, this is the rule to start with:
add_audio_bus stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every add_audio_bus call is checked against it from then on.
