WHAT IT DOES

What unity_animation_add_layer does on Unity MCP Server

AI agents use unity_animation_add_layer 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_add_layer is rated Medium

This tool creates or adds a new layer to an Animator Controller, which is a reversible modification of project data. It does not execute arbitrary code, delete data irreversibly, or trigger external financial operations. The severity is medium because incorrect layer additions could disrupt animation workflows and require manual correction, but changes can be undone in the editor.

From the tool's definition Tool name contains 'add' and description states 'Add a new layer to an Animator Controller' — this creates a new structural element within a game animation system.
