What can the App Store Connect MCP server do?
MCP is an open protocol that lets AI agents call tools in other apps.1 ButterKit exposes its entire screenshot pipeline as 42 tools your agent can drive.
Design from a prompt
Create artboards, apply templates, set marketing copy, and pose 3D devices with the design tools. Preview renders without leaving your editor.
Translate everything
Add languages and auto-translate every artboard plus your App Store metadata: description, promotional text, and What's New, in up to 50 languages.
Upload to App Store Connect
Create versions, then push screenshots and metadata per locale with the asc tools, through Apple's official App Store Connect API.2
Automate the whole pipeline
Pair it with fastlane or Simulator captures: new screenshots flow in, get framed and translated, and ship in a single agent session.
How do I set up the MCP server?
ButterKit v1.8 or later, with MCP enabled in Settings > MCP. No extra installs: the MCP bridge ships inside the app, and you point your agent at it.
Full setup options are in the MCP docs, and your agent can learn all 42 tools from the tool reference.

What does an end-to-end run look like?
One agent session takes raw captures to a live store listing. Describe the outcome; the agent sequences the tools.
- Capture
Link your fastlane or Simulator screenshot folder; new captures auto-map to the right devices.
design_link_screenshot_folder - Design
Apply a template, set the copy, pose the 3D devices, and preview the render.
design_apply_template · design_upsert_text_block - Translate
Add target languages; artboards and App Store metadata auto-translate.
localization_add_language · localization_translate_metadata - Ship
Upload screenshots and metadata for every locale to your App Store version.
asc_upload_screenshots · asc_upload_metadata - Keep your work
Unlike AI image generators, the agent produces real, editable design files that live on your Mac. Open them in ButterKit anytime to tweak, re-render, or export again, no credits or tokens holding your work hostage.

What is an App Store Connect MCP server?
MCP (Model Context Protocol) is an open standard that lets AI agents call tools in other applications. An App Store Connect MCP server exposes App Store actions, like uploading screenshots and metadata or managing versions, as tools an agent can call. ButterKit’s server pairs 7 App Store Connect tools with 35 design and localization tools, so your agent can produce the assets and ship them in the same session.
Is there an MCP server for App Store screenshots?
Yes. ButterKit’s MCP server is built specifically for App Store screenshots: agents can create artboards, apply templates, frame captures in 3D devices, translate every artboard, and upload the results to App Store Connect. It works with Claude Code, Claude Desktop, Cursor, OpenAI Codex and more.
Is there an ASC MCP for uploading screenshots and metadata?
Yes. The asc tools cover the App Store Connect side: check credentials, list your apps and versions, create a new version, and upload screenshots and metadata per locale through Apple’s official App Store Connect API.
Which AI agents work with ButterKit's MCP server?
Claude Code, Claude Desktop, Cursor, and OpenAI Codex all have step-by-step setup guides and 2-minute video tutorials. Because MCP is an open protocol, any MCP-compatible client can connect the same way.
Does the agent need ButterKit open?
ButterKit v1.8 or later must be running with a document open, since artboards render with ButterKit’s RealityKit engine. Add the –auto-launch flag to your MCP config and the bridge starts ButterKit automatically whenever your agent needs it. Uploading also requires your App Store Connect API key in ButterKit Settings.
Is the MCP server included in my license?
Yes. The MCP server is included in every ButterKit license at no extra cost, including all 42 tools and future additions.
