## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## 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 own 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."

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Sbox:
