WHAT IT DOES

What unity_particle_set_shape does on Unity MCP Server

AI agents use unity_particle_set_shape 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_set_shape is rated Medium

This tool creates or modifies particle system parameters (emission shape settings) within a Unity project, which is characteristic of Write operations. While it affects scene state, the changes are fully reversible by reconfiguring the shape again. The severity is medium because misconfiguration could affect game behavior or visual fidelity, but poses no data loss or external risk.

From the tool's definition Tool name 'unity_particle_set_shape' and description 'Configure the emission shape' indicate modifying particle system properties in an active Unity scene. This changes scene state (particle emitter configuration) but is reversible through reconfiguration.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs unity_particle_set_shape 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_set_shape, this is the rule to start with:

unity_particle_set_shape Rate-limited

unity_particle_set_shape 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 Unity MCP Server, apply this rule, and every unity_particle_set_shape call is checked against it from then on.

FAQ

Questions about unity_particle_set_shape

What does the unity_particle_set_shape tool do? +

Configure the emission shape: Sphere, Hemisphere, Cone, Box, Circle, Edge, etc. It is categorised as a Write tool in the Unity MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on unity_particle_set_shape? +

Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_particle_set_shape: 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_set_shape? +

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

Can I rate-limit unity_particle_set_shape? +

Yes. Add a rate_limit block to the unity_particle_set_shape 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_set_shape completely? +

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

unity_particle_set_shape is provided by the Unity MCP Server MCP server (anklebreaker-studio/unity-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
