Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "appscreen": {
      "command": "npx",
      "args": [
        "-y",
        "@appscreen/mcp"
      ],
      "env": {
        "APPSCREEN_API_KEY": "your-value",
        "APPSCREEN_BASE_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add appscreen --env APPSCREEN_API_KEY=your-value --env APPSCREEN_BASE_URL=your-value -- npx -y @appscreen/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "appscreen": {
      "command": "npx",
      "args": [
        "-y",
        "@appscreen/mcp"
      ],
      "env": {
        "APPSCREEN_API_KEY": "your-value",
        "APPSCREEN_BASE_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "appscreen": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@appscreen/mcp"
      ],
      "env": {
        "APPSCREEN_API_KEY": "your-value",
        "APPSCREEN_BASE_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is AppScreen safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: APPSCREEN_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.30.0) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@appscreen/mcp

MCP server for AppScreen — generate App Store / Play Store screenshots from any MCP-capable agent (Claude Desktop, Claude Code, Cursor, Codex, etc.).

Install

# Latest, no install — recommended for end users

npx -y @appscreen/mcp

Configure (Claude Desktop)

~/Library/Application Support/Claude/claude_desktop_config.json:

"mcpServers": { "appscreen": { "command": "npx", "args": ["-y", "@appscreen/mcp"], "env": { "APPSCREEN_API_KEY": "mcm_live_…" } } } }

Omit APPSCREEN_API_KEY for anonymous use (5 lifetime renders, then sign-up required).

Configure (other clients)

Claude Code: claude mcp add appscreen -- npx -y @appscreen/mcp
Cursor: .cursor/mcp.json — same JSON shape as above.
Codex: codex mcp add appscreen -- npx -y @appscreen/mcp, or add to ~/.codex/config.toml:

  [mcp_servers.appscreen]

command = "npx" args = ["-y", "@appscreen/mcp"] env = { APPSCREEN_API_KEY = "mcm_live_…" }

Tools

`render_screenshots` — Accepts screens (layout JSON) and image files. Returns a jobId (keyed/async) or a download link (anon/inline). Free anon use capped at 5 lifetime.
`get_render_status` — Polls a jobId. Returns status + signed download URL when done.

Pass images by path, not base64

The server runs locally, so give it a file path — it reads the bytes off disk. Do not base64-encode real screenshots into the call: an LLM emitting an 18k–90k-char base64 string drops a character partway down and the PNG renders black below it.

"files": [

{ "name": "1.png", "path": "~/app/screenshots/home.png" }, // ✅ preferred { "name": "2.png", "path": "/abs/path/settings.png" } ] // base64 is accepted only for tiny synthetic test images: // { "name": "x.png", "base64": "iVBORw0KG..." }

Bundle download URLs are signed and expire after ~1h. Re-poll to refresh.

Quota

Signed-in usage is metered in credits: 1 credit = 1 exported image (screens × sizes × languages). A failed export is refunded; auto-translate is free. An MCP key spends the credits of the workspace it was created in.

Plan	Credits / month	Notes
Free	50	Any one size per export, English, 10 screens per export. 3 renders / hour.
Starter — $4 / mo	400	All 5 sizes, any 3 languages per export, auto-translate. 3 renders / hour.
Pro — $8 / mo	2,500	All 15 languages, 200 screens per export. Full-rate MCP.
Team — $29 / mo	8,000 pooled	3 seats included. Full-rate MCP.

One-time credit packs work on every plan, including Free: 100 for $5, 400 for $15, 1,500 for $39, valid 12 months. Anonymous use (no key) is not metered in credits — it is capped at 5 renders, lifetime.

Every tool response includes _meta.quota = {used, cap, tier, resetAt}, plus balance (credits left) and, on a render submit, cost when the API reports them. For a signed-in caller used and cap count credits (cap − used = balance) and tier is the plan id; for an anonymous caller they count the 5 lifetime renders and tier is anon-mcp. When less than half is left the text content carries a short notice ("N credits left …"); below 20%, or at zero, the response also includes _meta.upgradeUrl.

An export the workspace can't cover fails with HTTP 402 insufficient_credits — the error text gives the cost and the balance. Full details: https://appscreen.co/pricing.

Environment

Var	Purpose
`APPSCREEN_API_KEY`	Optional. MCP key (`mcm_live_…`) from https://appscreen.co/account/keys. Works on every plan, Free included. Not the same as the programmatic `ask_live_…` API key.
`APPSCREEN_BASE_URL`	Override API URL. Defaults to `https://api.appscreen.co`.
`APPSCREEN_MCP_CLIENT`	Override client identifier (auto-detected from MCP initialize).
