WHAT IT DOES

What focus_object does on Sbox

AI agents invoke focus_object to trigger actions in Sbox. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why focus_object is rated High

Triggers an editor UI action (selection), a side effect beyond mere data retrieval.

From the tool's definition selecting it in the editor

RECOMMENDED RULE

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

focus_object Rate-limited

focus_object stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 focus_object call is checked against it from then on.

FAQ

Questions about focus_object

What does the focus_object tool do? +

Highlight a GameObject by selecting it in the editor. NOTE: s&box exposes no dedicated focus API, so this only sets the selection — it does NOT move any camera (returns { focused, id, note } saying so). To actually point the viewport at an object use frame_camera; to aim a screenshot use screenshot_from. It is categorised as a Execute tool in the Sbox MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on focus_object? +

Register the Sbox MCP server in PolicyLayer and add a rule for focus_object: 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 focus_object? +

focus_object is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit focus_object? +

Yes. Add a rate_limit block to the focus_object 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 focus_object completely? +

Set action: deny in the PolicyLayer policy for focus_object. 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 focus_object? +

focus_object 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.
