What set_transform does on Sbox
AI agents use set_transform 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 set_transform is rated Medium
This tool modifies game object properties (position, rotation, scale) but does not delete or irreversibly destroy data. Changes are reversible by calling the tool again with different values. It does not execute arbitrary code or trigger external operations beyond the game engine's transform system.
From the tool's definition Tool description states it 'Set[s] position, rotation, and/or scale on a GameObject' — modifying object properties in the game engine. The qualifier 'Only provided values are changed' indicates selective, reversible updates.
Attacks that exploit this kind of access
The rule that runs set_transform 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 set_transform, this is the rule to start with:
set_transform 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 set_transform call is checked against it from then on.
Questions about set_transform
Set position, rotation, and/or scale on a GameObject. Only provided values are changed. 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 set_transform: 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.
set_transform 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 set_transform 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 set_transform. 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.
set_transform 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.
