WHAT IT DOES

What add_light does on Sbox

AI agents use add_light 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_light is rated Medium

This tool creates a new light object in the game scene, which is a reversible modification of scene state. It does not execute arbitrary code, delete data, or cause financial impact. The severity is medium because misuse could clutter or degrade a game scene visually, but changes can be undone by removing the light.

From the tool's definition Tool name 'add_light' and description 'Add a light to the active scene' indicate creation of a new scene element. The note about intensity and colour magnitude confirms this creates/modifies scene state.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_light Rate-limited

add_light 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 add_light call is checked against it from then on.

FAQ

Questions about add_light

What does the add_light tool do? +

Add a light to the active scene. NOTE: s&box lights have no separate brightness field — intensity is the colour magnitude, so. 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_light? +

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

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

Can I rate-limit add_light? +

Yes. Add a rate_limit block to the add_light 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_light completely? +

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

add_light 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.
