createParticles · Maige 3d MCP: Risk & Policy

WHAT IT DOES

What createParticles does on Maige 3d

AI agents use createParticles 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 createParticles needs a policy

This tool creates a new particle system in the 3D scene. It adds new data/objects to the scene reversibly (particles can be deleted via deleteParticles sibling tool), making it a Write operation. Severity is medium as misuse could clutter or disrupt the 3D scene but has no broader system impact.

From the tool's definition Create a particle system (stars, dust, sparks, snow, fire embers, laser trails)

Verdict

createParticles Rate-limited

createParticles 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 createParticles

What does the createParticles tool do? +

Create a particle system (stars, dust, sparks, snow, fire embers, laser trails). 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 createParticles? +

Register the Maige 3d MCP server in PolicyLayer and add a rule for createParticles: 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 createParticles? +

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

Can I rate-limit createParticles? +

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

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

createParticles 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.
