Your First Prompt

After installing the package and connecting a client, try a concrete Unity task.

Prerequisites​

  • Install is complete
  • MCP for Unity reports Connected
  • A scene is open in Unity Editor

The prompt​

Create a red, blue, and yellow cube in the current scene, spaced one unit apart on the X axis.

The assistant should inspect the scene, create three cubes, create or assign colored materials, and attach the materials to the MeshRenderers.

What you should see​

Three cubes appear in the Hierarchy and Scene view. If a URP/HDRP project shows gray materials, explicitly ask the assistant to use the correct shader.

Next prompts​

Add a directional light and a perspective camera looking at the cubes.

Write a C# script that makes the red cube oscillate and enter Play mode.

Run all EditMode tests and report failures.

When something goes wrong​

  • I couldn't find any Unity instance — check the MCP for Unity status panel.
  • Multiple Unity instances detected — see Multi-Instance Routing.
  • Tool calls succeed but nothing happens — inspect tool-group visibility with manage_tools action list_groups.
