WHAT IT DOES

What set_fog does on Sbox

AI agents use set_fog 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 set_fog is rated Medium

This tool modifies the game scene by adding or updating fog properties, which is a creative/design operation. It does not execute arbitrary code, delete data irreversibly, or cause external side effects beyond the game environment. The reversibility and non-destructive nature places it in Write rather than Execute or Destructive.

From the tool's definition set_fog adds or updates fog in the active scene, modifying scene state with an operation that is reversible (fog can be removed or changed to different parameters).

RECOMMENDED RULE

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

set_fog Rate-limited

set_fog 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.
