WHAT IT DOES

What create_round_phase_machine does on Sbox

AI agents use create_round_phase_machine 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 create_round_phase_machine is rated Medium

This tool creates new game state objects (a round/phase machine with synced properties and events) and can modify existing GameObjects by attaching to them via GUID. These are reversible operations typical of Write category.

From the tool's definition Tool generates and creates a new phase machine with CurrentPhase synchronization, event firing, and optional attachment to GameObjects. Keywords: 'Generate', 'creates', 'attached to an existing GameObject' indicate data structure creation and modification.

RECOMMENDED RULE

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

create_round_phase_machine Rate-limited

create_round_phase_machine 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.

FAQ

Questions about create_round_phase_machine

What does the create_round_phase_machine tool do? +

Generate a host-authoritative round/phase machine: a [Sync(SyncFlags.FromHost)] CurrentPhase cycled through your named phases on a per-phase timer (host-only), with a static OnPhaseChanged event that fires on every machine. Great for round/match flow, match phases, or a day/night cycle. Single-player safe. Optionally attached to an existing GameObject by GUID (after a hotload). Mined from the round-flow pattern across the 51 games. 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.

How do I enforce a policy on create_round_phase_machine? +

Register the Sbox MCP server in PolicyLayer and add a rule for create_round_phase_machine: 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.

What risk level is create_round_phase_machine? +

create_round_phase_machine is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_round_phase_machine? +

Yes. Add a rate_limit block to the create_round_phase_machine 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.

How do I block create_round_phase_machine completely? +

Set action: deny in the PolicyLayer policy for create_round_phase_machine. 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.

What MCP server provides create_round_phase_machine? +

create_round_phase_machine 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.
