screenshot-camera	Capture a screenshot from a Unity `Camera` and return it as a PNG image for direct LLM inspection. Falls back to `Camera.main` (then any active camera) when `cameraRef` is null. Width and height are capped to keep response size manageable.	generated-by mcp-plugin-dotnet

Screenshot / Camera

Captures a screenshot from a camera and returns it as an image. If no camera is specified, uses the Main Camera. Returns the image directly for visual inspection by the LLM.

Inputs

• cameraRef (optional) — reference to a GameObject hosting a Camera. When null, Camera.main is used; if there is no main camera, the first entry of Camera.allCameras is used.
• width (default 1920) / height (default 1080) — output pixels. Must be > 0 and ≤ MaxDimension.

Behavior

Allocates a temporary RenderTexture, swaps it onto the chosen camera, calls Camera.Render, reads back via Texture2D.ReadPixels, encodes as PNG, and restores the camera's prior targetTexture. Returns a ResponseCallTool.Image with image/png MIME and a descriptive caption.

How to Call

unity-mcp-cli run-tool screenshot-camera --input '{
  "cameraRef": "string_value",
  "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-camera --input-file args.json

Or pipe via stdin (recommended):

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