What audio_player_create does on Breakpoint
AI agents use audio_player_create 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 |
|---|---|---|---|
bus | string | — | Target audio bus name (default "Master") |
dim | string | — | Player kind: "none" (default, AudioStreamPlayer), "2d" (AudioStreamPlayer2D), or "3d" (AudioStreamPlayer3D) |
name | string | — | Node name (default matches the player class) A taken name gets a number appended (`SFX`->`SFX2`), reported as `coerced` + `requested`. |
autoplay | boolean | — | Whether the player starts automatically on scene load |
volume_db | number | — | Player volume in dB |
parent_path | string | Yes | Parent node path relative to the scene root; "." for the root |
stream_path | string | — | res:// path to an AudioStream to assign to the new player |
Parameters from the server's own tool schema.
Why audio_player_create is rated Medium
An AI agent can call audio_player_create faster than any human can review: one bad instruction and it creates or modifies resources in Breakpoint by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs audio_player_create 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_player_create, this is the rule to start with:
audio_player_create 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 Breakpoint, apply this rule, and every audio_player_create call is checked against it from then on.
Questions about audio_player_create
Add an AudioStreamPlayer / AudioStreamPlayer2D / AudioStreamPlayer3D node under a parent in the edited scene (undoable). dim selects "none" (default, non-positional AudioStreamPlayer), "2d", or "3d". Optional initial stream_path (res:// AudioStream), autoplay, volume_db, bus. In-scene and undoable — not gated. It is categorised as a Write tool in the Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
audio_player_create accepts 7 parameters: bus, dim, name, autoplay, volume_db, parent_path, stream_path. Required: parent_path. The full parameter table on this page comes from the server's own tool schema.
Register the Breakpoint MCP server in PolicyLayer and add a rule for audio_player_create: 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 Breakpoint. Nothing to install.
audio_player_create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the audio_player_create 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.
Set action: deny in the PolicyLayer policy for audio_player_create. 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.
audio_player_create is provided by the Breakpoint MCP server (breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
