WHAT IT DOES

What equip_model does on Sbox

AI agents use equip_model 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 equip_model is rated Medium

The tool creates or modifies entity properties within the game engine by attaching props to citizens. This is a reversible state change (props can be unequipped) with moderate blast radius — an AI agent could inappropriately equip props, cluttering or confusing gameplay. It does not execute arbitrary code, delete data irreversibly, or move money, so Write is the appropriate category.

From the tool's definition Tool description states 'Attach a prop model...to a Citizen' — this modifies game state by attaching visual/interactive objects to player entities. It is a create/modify operation that changes game world configuration.

RECOMMENDED RULE

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

equip_model Rate-limited

equip_model 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.
