StoreShots

StoreShots MCP

Turn raw app screenshots into polished App Store and Google Play marketing screenshots from Cursor, Claude, or any other MCP client.

This is a small stdio MCP server that talks to the hosted StoreShots API. Rendering happens on the server, so you don't need Chrome, Puppeteer, or a design tool on your machine. Give your agent a few screenshots and some headlines, and it saves store-ready PNGs (or a ZIP) into your project.

• 1–5 screenshots per set, from local files or URLs
• 5 curated styles: glow, midnight, sunset, mint, trailing, plus custom colours
• Device frames: iphone, iphone-duo, android, ipad
• Every required store size in one call: ios-6.9 (1320×2868), ios-6.5 (1242×2688), android-phone (1080×1920), ipad-13 (2064×2752)
• Headlines and captions for each slide
• Downloads a ZIP and/or PNGs straight into your project

Quick start

1. Get a free API key

Sign up with your email at https://storeshots.qaimos.co.uk/account.html. The key (ss_...) is only shown once, so copy it somewhere safe.

2. Add the server to your MCP client

Cursor: add this to ~/.cursor/mcp.json (or to .cursor/mcp.json in a project). You can also use the "Install in Cursor" button above.

{
  "mcpServers": {
    "storeshots": {
      "command": "npx",
      "args": ["-y", "storeshots-api-mcp"],
      "env": { "STORESHOTS_API_KEY": "ss_your_key_here" }
    }
  }
}

Claude Desktop: open Settings → Developer → Edit Config, then add the same block to claude_desktop_config.json:

{
  "mcpServers": {
    "storeshots": {
      "command": "npx",
      "args": ["-y", "storeshots-api-mcp"],
      "env": { "STORESHOTS_API_KEY": "ss_your_key_here" }
    }
  }
}

Claude Code:

claude mcp add storeshots --env STORESHOTS_API_KEY=ss_your_key_here -- npx -y storeshots-api-mcp

VS Code, Windsurf, and other clients: run npx -y storeshots-api-mcp over stdio with STORESHOTS_API_KEY set in the environment.

Requires Node.js 18.17 or newer.

3. Ask your agent

Make App Store screenshots from ./shots/home.png and ./shots/stats.png in the midnight style with the headlines "Build habits that stick" and "See your progress", and save them to ./store-assets.
