What assign_sound does on Sbox
AI agents use assign_sound to create or update resources in Sbox, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sbox environment.
Why assign_sound is rated Medium
This tool modifies game state by adding or updating a component (SoundPointComponent) on a GameObject. While it creates or modifies data structures, these changes are reversible—a user can remove or reassign the sound later.
From the tool's definition The tool 'assign_sound' performs a reversible modification: it attaches a sound event to a GameObject and 'Creates the component if needed'. This is a create/modify operation within the game engine's object model.
Attacks that exploit this kind of access
The rule that runs assign_sound safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Sbox, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For assign_sound, this is the rule to start with:
assign_sound 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 Sbox, apply this rule, and every assign_sound call is checked against it from then on.
Questions about assign_sound
Attach a sound event to a GameObject via SoundPointComponent. Creates the component if needed. It is categorised as a Write tool in the Sbox MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sbox MCP server in PolicyLayer and add a rule for assign_sound: 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 Sbox. Nothing to install.
assign_sound 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 assign_sound 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 assign_sound. 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.
assign_sound is provided by the Sbox MCP server (sbox-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
