Screenshot / Scene View

Captures a screenshot from the Unity Editor Scene View and returns it as an image. Returns the image directly for visual inspection by the LLM.

Inputs

• width (default 1920) / height (default 1080) — output pixels. Must be > 0 and ≤ MaxDimension.

Behavior

Uses SceneView.lastActiveSceneView (falls back to the first window in SceneView.sceneViews). Allocates a temporary RenderTexture, swaps it onto the Scene View's camera, calls Render, reads back with Texture2D.ReadPixels, encodes PNG, and restores the camera's prior targetTexture. Throws/errors when no Scene View is open or the Scene View camera is null.

How to Call

unity-mcp-cli run-tool screenshot-scene-view --input '{
  "width": 0,
  "height": 0
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool screenshot-scene-view --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool screenshot-scene-view --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.
