WHAT IT DOES

What audio_set_stream does on Godot Breakpoint

AI agents use audio_set_stream 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.

RISK

Why audio_set_stream is rated Medium

This tool modifies scene data (assigns an audio stream to a player node) in a reversible manner. While it changes the edited scene, the modification is not permanent—it can be undone. This places it firmly in the Write category. The medium severity reflects that misuse could alter audio design or create unintended audio playback, but the blast radius is limited to a single scene property and reversible via undo.

From the tool's definition The description explicitly states the tool 'Load[s] an AudioStream from a res:// path and assign[s] it as stream on an AudioStreamPlayer', which modifies scene state.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

audio_set_stream Rate-limited

audio_set_stream 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.

How do I enforce a policy on audio_set_stream? +

Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for audio_set_stream: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot Breakpoint. Nothing to install.

What risk level is audio_set_stream? +

Can I rate-limit audio_set_stream? +

Yes. Add a rate_limit block to the audio_set_stream rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block audio_set_stream completely? +

Set action: deny in the PolicyLayer policy for audio_set_stream. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
