WHAT IT DOES

What unity_animation_assign_controller does on Unity MCP Server

AI agents use unity_animation_assign_controller 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_animation_assign_controller is rated Medium

This tool creates or modifies data (adds an Animator component and assigns a controller) within the Unity scene. It does not execute arbitrary code, delete data, or cause financial harm. The modification is reversible—the component can be removed or the controller reassigned. While it affects scene structure, this is a standard Write operation.

From the tool's definition Tool description states it 'Assign[s] an Animator Controller to a GameObject (adds Animator component if needed)'. This modifies scene state by adding or updating components on GameObjects, which is a reversible change to the Unity project.

RECOMMENDED RULE

The rule that runs unity_animation_assign_controller 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_animation_assign_controller, this is the rule to start with:

unity_animation_assign_controller Rate-limited

unity_animation_assign_controller 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.

Questions about unity_animation_assign_controller

What does the unity_animation_assign_controller tool do? +

Assign an Animator Controller to a GameObject (adds Animator component if needed). 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_animation_assign_controller? +

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

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

Can I rate-limit unity_animation_assign_controller? +

Yes. Add a rate_limit block to the unity_animation_assign_controller 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_animation_assign_controller completely? +

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

unity_animation_assign_controller 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.
