WHAT IT DOES

What set_audio_bus_volume does on Godot

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

Parameter	Type	Required	Description
`bus`	string	Yes	Bus name (e.g. 'Master', 'Music', 'SFX')
`volume_db`	number	Yes	Volume in decibels (0 = normal, negative = quieter)

Parameters from the server's own tool schema.

RISK

Why set_audio_bus_volume is rated Medium

This tool modifies audio bus properties (volume level) within the Godot engine, which is a reversible configuration change. It does not execute arbitrary code, delete data, or move money. While it affects audio output, the change is non-destructive and can be undone by setting a different volume value.

From the tool's definition Tool name 'set_audio_bus_volume' and description 'Set the volume of a specific audio bus' indicate modification of audio configuration state.

RECOMMENDED RULE

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

set_audio_bus_volume Rate-limited

set_audio_bus_volume 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.
