What create_objective_system does on Sbox
AI agents use create_objective_system 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 create_objective_system is rated Medium
This tool creates/generates a new C# component (ObjectiveManager) and optionally places it as a scene singleton. It is a write/create operation — producing new code and modifying the game scene. No irreversible deletion, financial transaction, or arbitrary code execution is implied; it is a structured asset/component creation action within the s&box game engine editor context.
From the tool's definition Generate an ObjectiveManager component — Self-contained C#; Optionally placed as a scene singleton
Attacks that exploit this kind of access
The rule that runs create_objective_system 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 create_objective_system, this is the rule to start with:
create_objective_system 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 create_objective_system call is checked against it from then on.
Questions about create_objective_system
Generate an ObjectiveManager component — the win/lose brain of a game. Tracks an objective (collect_all / reach_goal / survive_time / eliminate_all), fires a win, and handles a lose condition (fall below kill-Z / timer / out of lives). Self-contained C#; other systems call ObjectiveManager.Instance. Optionally placed as a scene singleton. It is categorised as a Write tool in the Sbox MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sbox MCP server in PolicyLayer and add a rule for create_objective_system: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Sbox. Nothing to install.
create_objective_system is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_objective_system rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_objective_system. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
create_objective_system is provided by the Sbox MCP server (sbox-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
