WHAT IT DOES

What add_envmap_probe does on Sbox

AI agents use add_envmap_probe 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 add_envmap_probe is rated Medium

Creates new game engine objects that modify scene state reversibly; requires follow-up baking to take effect.

From the tool's definition Add environment reflection probe, captures reflections and indirect light

RECOMMENDED RULE

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

add_envmap_probe Rate-limited

add_envmap_probe 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 add_envmap_probe

What does the add_envmap_probe tool do? +

Add an environment reflection/ambient probe (EnvmapProbe) at a position with a cubic influence volume — captures local reflections and indirect light for nearby surfaces. IMPORTANT: a placed probe captures NOTHING until baked — follow with bake_reflections. Returns { created, gameObject } — gameObject.id is the probe object. 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 add_envmap_probe? +

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

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

Can I rate-limit add_envmap_probe? +

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

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

add_envmap_probe 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.
