WHAT IT DOES

What create_gameobject does on Sbox

AI agents use create_gameobject 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.

RISK

Why create_gameobject is rated Medium

This tool creates new game objects within an active scene, which is a write operation that modifies the game world state. However, since game object creation is reversible (objects can be deleted), it does not rise to Destructive. It does not execute arbitrary code or trigger external operations beyond object instantiation, so it is not Execute.

From the tool's definition Tool description states 'Create a new GameObject in the active scene.' The verb 'Create' and the context of instantiating new game objects in a scene represent reversible data modification within the game engine.

RECOMMENDED RULE

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

create_gameobject Rate-limited

create_gameobject 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Sbox, apply this rule, and every create_gameobject call is checked against it from then on.
