WHAT IT DOES

What add_world_panel does on Sbox

AI agents use add_world_panel 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 add_world_panel is rated Medium

This tool creates new game objects within the s&box engine, which is a reversible modification of game state. It does not execute arbitrary code, delete data, or cause financial impact. The blast radius is medium because an agent could spam panel creation to degrade performance or clutter the game world, but the effect is easily undone by removing objects.

From the tool's definition Tool name 'add_world_panel' and description states it will 'Create a new GameObject' — this is a creation operation that modifies the game state by adding a new entity.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_world_panel Rate-limited

add_world_panel 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.
