WHAT IT DOES

What add_network_helper does on Sbox

AI agents use add_network_helper 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_network_helper is rated Medium

This tool performs scene creation/modification operations (adding a component, setting up multiplayer infrastructure) that alter game state but are not irreversible. While it affects multiplayer behavior and player spawn logic, these changes can be undone or modified in the editor. It does not execute arbitrary code or permanently delete data, and it does not move money.

From the tool's definition Tool creates or modifies a game scene by adding a NetworkHelper component and handles 'lobby creation and player prefab spawning' — side effects that are reversible through scene editing.

add_network_helper Rate-limited

add_network_helper 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.
