Set the transform (position, rotation, scale) of a GameObject.
AI agents use unity_gameobject_set_transform to create or update resources in Unity MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Unity MCP Server environment.
This tool modifies the spatial properties of a GameObject in the Unity scene. It creates a reversible change to transform data (position, rotation, scale), which is a Write operation. While it modifies scene state, the change can be undone, so it doesn't qualify as Destructive. Misuse could displace or hide objects in a scene but is generally recoverable.

Documented attack patterns abuse exactly the kind of access unity_gameobject_set_transform gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Unity MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for unity_gameobject_set_transform:
{
"version": "1",
"default": "deny",
"tools": {
"unity_gameobject_set_transform": {
"limits": [
{
"counter": "unity_gameobject_set_transform_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}unity_gameobject_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.

Set the transform (position, rotation, scale) of a GameObject. It is categorised as a Write tool in the Unity MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_gameobject_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 Unity MCP Server. Nothing to install.
unity_gameobject_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 unity_gameobject_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 unity_gameobject_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.
unity_gameobject_set_transform is provided by the Unity MCP Server MCP server (anklebreaker-studio/unity-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
