Screenshot / Game View

Captures a screenshot from the Unity Editor Game View and returns it as an image. Reads the Game View's own render texture directly via the Unity Editor API. The image size matches the current Game View resolution. Returns the image directly for visual inspection by the LLM.

Behavior

Locates UnityEditor.GameView, repaints it, then reflects the m_RenderTexture field and reads back via Texture2D.ReadPixels. On graphics APIs whose UV origin is top-left (SystemInfo.graphicsUVStartsAtTop), the read-back pixels are vertically flipped before encoding so the orientation matches what the user sees. Returns a PNG image with the resolution baked into the caption.

How to Call

unity-mcp-cli run-tool screenshot-game-view --input '{
  "nothing": "string_value"
}'

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

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

Or pipe via stdin (recommended):

unity-mcp-cli run-tool screenshot-game-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.
