ShotLingo MCP: App Store screenshot generator for Claude, Cursor and VS Code

Tell your agent: "make my App Store screenshots in 12 languages and upload them."

It designs the set, writes the captions in 41 languages, ShotLingo renders the pixels,

the set goes straight to App Store Connect or Google Play , and it can start an App Store product page A/B test with it.

Connect in one line

Server URL: https://mcp.shotlingo.com/mcp (hosted, streamable HTTP, sign in with your ShotLingo account on the first tool call, no API key to copy).

claude mcp add --transport http shotlingo https://mcp.shotlingo.com/mcp

Then ask Claude Code something from the list below. For Claude web and desktop, Cursor, VS Code and stdio-only clients see Install.

The MCP connector needs a paid ShotLingo plan (Pro, Plus or Studio); store upload and A/B tests need Plus or Studio. Limits are on shotlingo.com/plans. The skills and the store page audit in this repo are free and need no account.

What you can ask for

1. Build a set from your own screens

"Make a 6.9-inch App Store set for my habit tracker from these five simulator screenshots, one benefit per screen."

Uses create_project, import_image, generate_page, apply_device_frame. Or start from list_templates, get_template and adapt_template.

2. Localize and render everything

"Translate the set into German, Japanese and Brazilian Portuguese and render all of it."

Uses set_translations (41 languages, right-to-left included), start_batch and get_batch_status.

3. Fix captions that do not fit

"Which captions overflow in German? Shorten them and re-render only those pages."

Uses fit_text_into_design and render_screenshot. Text is fitted by the same export pipeline the ShotLingo web editor uses, so a long German caption shrinks to fit instead of spilling off the frame.

4. Upload, then test it

"Upload the localized set to App Store Connect, then set up a product page A/B test with it."

Uses list_app_store_apps, export_to_app_store (and export_to_google_play for Android), then estimate_ab_test, create_ab_test, list_ab_tests, record_ab_result and stop_ab_test.

Undo is built in. save_version before a risky edit, restore_version to go back; deleted projects come back with restore_project.

Install

Claude Code plugin (MCP server + screenshot design skill + ShotLingo tool guide skill + /shotlingo:localize command)

claude plugin install shotlingo --marketplace AlperenGuntekin/shotlingo-mcp

Inside a Claude Code session, or on a Claude Code version older than 2.1.292:

/plugin marketplace add AlperenGuntekin/shotlingo-mcp

/plugin install shotlingo@shotlingo

Then run /mcp, pick plugin:shotlingo:shotlingo and sign in.

Claude (web and desktop): Settings, Connectors, Add custom connector, paste https://mcp.shotlingo.com/mcp.

Cursor: Add to Cursor, or put this in ~/.cursor/mcp.json:

{ "mcpServers": { "shotlingo": { "url": "https://mcp.shotlingo.com/mcp" } } }

VS Code:

code --add-mcp '{"name":"shotlingo","type":"http","url":"https://mcp.shotlingo.com/mcp"}'

Clients that only speak stdio:

{ "mcpServers": { "shotlingo": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.shotlingo.com/mcp"] } } }

The first tool call opens a browser window to sign in to ShotLingo (OAuth 2.1 with PKCE). Nothing is stored in this repo.

Tools by step

The full, current tool list is what the server returns from tools/list; some tools appear only for accounts that have the matching feature on.

Try it free: audit any App Store page

No account, no key. One GET, sourced from Apple's public data:

curl -s "https://mcp.shotlingo.com/audit?app=https://apps.apple.com/us/app/id6748750121&format=md"

Real output for one of our own apps (excerpt, read 2026-10-29):

# Store page audit: Breaker: Conversation Starters (US)

• [medium] 5 of 10 iPhone screenshot slots used. 5 slots are unused. The top 5 free apps in Entertainment (US) use a median of 6 iPhone screenshots.
• [info] 0 of 10 major storefronts show the same screenshot files as US. Every storefront checked has its own screenshot files.
• [info] 0 iPad screenshots. 4 of 5 top apps in your category have iPad screenshots.
• [info] 2 ratings in US, average 5.0. Median of the top 5 in your category: 99314 ratings.

It checks 10 major storefronts for untranslated screenshots and descriptions, flags languages your app speaks but its store page does not show, and compares you with the top free apps in your category. What the public data cannot show (caption text, App Previews) is listed as not measured.

Skills

npx skills add AlperenGuntekin/shotlingo-mcp

Installs three skills into Claude Code, Cursor, Codex and the other agents the skills CLI supports. They are free and need no account:

• `store-audit`: runs the free store page audit above and reads the result back without adding claims.
• `app-store-screenshots`: the screenshot design rules we use: what the first three screens must do, caption length, sizes, localization traps, App Review rules.
• `shotlingo`: how to drive the ShotLingo tools: which ones only read, which ones edit the design and which ones touch a live listing, how to undo with saved versions, render without hitting the rate limit, and set up an App Store product page test.

The Claude Code plugin also adds the /shotlingo:localize command: one command from "here is my English set" to a rendered, localized set.

How it works

your agent ──MCP over HTTPS──▶ mcp.shotlingo.com ──▶ ShotLingo renderer ──▶ PNGs / App Store Connect / Google Play

The server is hosted and closed source. This repo is the open part: client configs, the Claude Code plugin and the skills. Bugs and feature requests for the server are welcome here as issues. The ShotLingo web editor at shotlingo.com has a free plan.

Privacy

This repo collects nothing: it is configuration and Markdown. What the hosted service stores is described in shotlingo.com/privacy.

Contributing

Better screenshot rules, client configs for more editors, and clearer docs are all welcome. Open a pull request or an issue. Run npm test before you push.
