What audio_set_bus_layout does on Godot Breakpoint
AI agents use audio_set_bus_layout to create or update resources in Godot Breakpoint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot Breakpoint environment.
Why audio_set_bus_layout is rated Medium
This tool modifies (or creates) a file on disk, which is a Write operation. Although the description uses the word 'DESTRUCTIVE', the actual capability is file writing/overwriting of a resource file, not irreversible deletion. The confirmation gate further reduces severity from what an unconfirmed destructive operation would carry.
From the tool's definition Tool description explicitly states it 'Save[s] the current AudioServer bus layout... to a .tres resource on disk' via 'ResourceSaver.save'. The description labels it 'DESTRUCTIVE (writes a file)' but clarifies it is 'gated by confirmation'.
Attacks that exploit this kind of access
The rule that runs audio_set_bus_layout safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For audio_set_bus_layout, this is the rule to start with:
audio_set_bus_layout 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 Breakpoint, apply this rule, and every audio_set_bus_layout call is checked against it from then on.
