WHAT IT DOES

What unity_ui_set_text does on Unity MCP Server

AI agents use unity_ui_set_text 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_ui_set_text is rated Medium

This tool modifies UI text properties reversibly. Setting text content, font size, color, or alignment are write operations that change visual properties of a game UI component but do not execute code, delete data irreversibly, or cause side effects outside the intended scope. The changes can be undone by setting different values.

From the tool's definition Tool name 'unity_ui_set_text' and description explicitly states it 'Set properties on a UI Text component' including text content, fontSize, color, and alignment. These are modifications to UI component properties.
