WHAT IT DOES

What load_scene does on Sbox

AI agents invoke load_scene 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 load_scene is rated High

This tool triggers an external operation in the s&box editor (opening/loading a scene), which is an active action with side effects in the game engine environment. It is not purely reading data — it changes the editor state by loading a scene. It falls under Execute as it triggers an external operation whose effect is determined by the path argument.

RECOMMENDED RULE

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

load_scene Rate-limited

load_scene 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 load_scene call is checked against it from then on.

FAQ

Questions about load_scene

What does the load_scene tool do? +

Open a scene in the s&box editor by its path. 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 load_scene? +

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

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

Can I rate-limit load_scene? +

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

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

load_scene 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.
