MCP Tool Turns Screenshots into App Store Previews

The creator built an MCP server that takes app screenshots from a folder and uses Claude to generate App Store-ready preview images.
Key Workflow
- Claude analyzes the app's color scheme to propose themes and copy
- It waits for user confirmation before rendering the final assets
- Outputs 1284×2778 preview images with device frames and titles, ready for direct upload to App Store Connect
Implementation Details
- Developed using Claude Code
- Uses Pillow to programmatically draw the iPhone bezel, eliminating the need for static image assets
- A palette extractor automatically generates brand-matching themes
- Wrapped into 3 stdio tools using the official mcp SDK
- Installed effortlessly via a single uvx command
