# How to Add Watermarks with Claude

Claude makes watermarking an iterative terminal workflow. Describe your watermark requirements -- logo placement, opacity, style -- and Claude asks clarifying questions about the intended use case before applying. Preview the result on a test image first, adjust positioning and transparency with conversational feedback, then batch-apply the finalized settings across your library.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Add a watermark to this image using image-ops -- use our company logo in the bottom right"
3. Claude applies the watermark using transform_image
4. Review the watermarked image and adjust opacity or position as needed
5. Ask Claude to apply the same watermark to your entire image batch

## Example Prompt

```
Add our logo watermark to all product images. Place it in the bottom right at 30% opacity.
```

## Tips

- Ask Claude to test different watermark positions and opacities before batch processing
- Request watermark styles appropriate for different use cases -- preview vs distribution
- Claude can apply different watermarks based on image content or destination
