WHAT IT DOES

What audio_set_bus_layout does on Breakpoint

AI agents use audio_set_bus_layout to create or update resources in Breakpoint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Breakpoint environment.

Parameter	Type	Required	Description
`confirm`	boolean	—	Auto-approve this destructive action (skip the confirmation prompt)
`to_path`	string	—	Destination res:// path (default res://default_bus_layout.tres)

Parameters from the server's own tool schema.

RISK

Why audio_set_bus_layout is rated Medium

This tool writes/overwrites a file on disk (a .tres resource). While the description labels it 'DESTRUCTIVE', it writes/saves data rather than deleting or irreversibly destroying it — the file can be restored or overwritten again. The most accurate category is Write (creates or modifies data on disk).

From the tool's definition Save the current AudioServer bus layout (buses, effects, volumes) to a .tres resource on disk via generate_bus_layout + ResourceSaver.save. DESTRUCTIVE (writes a file) — gated by confirmation.

RECOMMENDED RULE

The rule that runs audio_set_bus_layout safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 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 Rate-limited

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.
