MCP Support: AI-Powered Screenshot Generation and Localization
ButterKit now speaks MCP. Generate full screenshot sets, localize into all 39 App Store languages, and upload to App Store Connect from any AI assistant or CI pipeline. Everything stays fully editable.
What's in this release
NEW New Features
- MCP server support (beta): connect ButterKit to Claude, Cursor, Codex, or any MCP-compatible AI assistant and control it with natural language prompts.
- Generate a full screenshot set from a description of your app. No design skills needed.
- Localize into all 39 App Store localizations in one prompt: screenshots, descriptions, and What's New text.
- CI pipeline integration: e.g. Fastlane or Xcode Cloud runs UI tests, ButterKit refreshes screenshots, translates, and uploads automatically.
- Swap to holiday branding across all languages, then revert with one prompt. Seasonal campaigns aren't just for big teams anymore.
- Change a headline and re-translate every language at once.
- Generate iPad and Mac screenshots from your existing iPhone set.
Full Release Notes
v1.8 introduces MCP support (beta), letting you drive ButterKit from any AI assistant or automation pipeline. Unlike AI image generators that output flat PNGs you can’t easily change, everything ButterKit creates stays fully editable: text, real 3D devices, backgrounds, layouts. The AI builds it, you own it.
Please note the Mac App Store build is still in development (additional entitlement testing). Feedback is welcome: let me know what works, what’s confusing, or what you’d like to see next.
