I built an MCP server that turns app screenshots into App Store-ready preview images
My first ever mcp server that lets you drop your raw screenshots in a folder and say "create App Store mockups for these." Claude analyzes your app's colors, proposes themes and captions, waits for your approval, then renders framed, captioned preview images (1284×2778) ready to upload to App Store Connect. Open source, installs with one uvx command.
I used claude code to build a tool in which Pillow draws the whole iPhone frame procedurally (no assets), a palette extractor picks brand-matched themes, and the official mcp SDK wraps it in three stdio tools.
