# How to Create Marketing Banners with Claude

Claude turns banner creation into a conversational workflow right in your terminal. Describe your campaign concept, iterate on colors and layout through back-and-forth dialogue, and generate multiple A/B test variations without leaving your development environment. The multi-step creative process feels natural because Claude remembers your brand guidelines throughout the session.

## Setup

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

1. Connect ToolRouter to Claude: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Describe your banner: "Generate a 1200x628 marketing banner for a summer sale with bold typography and warm colors"
3. Claude calls text_to_image and returns the generated banner image
4. Iterate on the design: "Make the text larger and add a 20% off badge in the corner"
5. Ask Claude to generate multiple variations for A/B testing

## Example Prompt

```
