What add_lipsync does on Sbox
AI agents use add_lipsync 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.
Why add_lipsync is rated Medium
This tool creates or wires new lipsync components into the game, which is a reversible modification operation (Write category). Severity is medium because misuse could corrupt game assets or create invalid component configurations, but changes can typically be undone in a game editor.
From the tool's definition Tool name 'add_lipsync' and description 'Add + wire s&box' indicate the tool creates or modifies game engine components (lipsync configuration wired into the s&box game).
Attacks that exploit this kind of access
The rule that runs add_lipsync 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_lipsync, this is the rule to start with:
add_lipsync 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Sbox, apply this rule, and every add_lipsync call is checked against it from then on.
