createLight · Maige 3d MCP: Risk & Policy

WHAT IT DOES

What createLight does on Maige 3d

AI agents use createLight to create or update resources in Maige 3d — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Maige 3d environment.

WHY IT NEEDS A POLICY

Why createLight needs a policy

Creating a light in a 3D scene is a Write operation—it modifies the scene state by adding an object, but the change is reversible and has no destructive, financial, or code-execution implications. The blast radius is minimal; a mistakenly added light causes only visual/rendering changes within the 3D viewport.

From the tool's definition Tool name 'createLight' and description 'Add a light to the scene' indicate creation of a 3D scene object. This is a reversible modification (the light can be deleted via 'deleteLight').

Verdict

createLight Rate-limited

createLight 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Maige 3d, so you can run agents against it safely.

FAQ

Questions about createLight

What does the createLight tool do? +

Add a light to the scene. It is categorised as a Write tool in the Maige 3d MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on createLight? +

Register the Maige 3d MCP server in PolicyLayer and add a rule for createLight: 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 Maige 3d. Nothing to install.

What risk level is createLight? +

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

Can I rate-limit createLight? +

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

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

createLight is provided by the Maige 3d MCP server (m-ai-gexr/mcp-webgpu). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
