WHAT IT DOES

What unity_particle_create does on Unity MCP Server

AI agents use unity_particle_create to create or update resources in Unity MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Unity MCP Server environment.

RISK

Why unity_particle_create is rated Medium

This tool creates a new Particle System asset, which is a reversible modification to a Unity project. It does not execute arbitrary code, delete data, or trigger financial transactions. While it modifies project state, the creation can be undone (undo/delete the created system), making it Write rather than Destructive.

From the tool's definition Tool name 'unity_particle_create' and description 'Create a new Particle System with optional initial settings' indicate creation of a new game object/asset within a Unity scene.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs unity_particle_create safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Unity MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unity_particle_create, this is the rule to start with:

unity_particle_create Rate-limited

unity_particle_create 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 unity_particle_create

What does the unity_particle_create tool do? +

How do I enforce a policy on unity_particle_create? +

Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_particle_create: 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 Unity MCP Server. Nothing to install.

What risk level is unity_particle_create? +

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

Can I rate-limit unity_particle_create? +

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

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