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

Tools

render_screenshots — Accepts screens (layout JSON) and PNG files (base64). Returns a jobId and queues the render. Free anon use capped at 5 lifetime.
get_render_status — Polls a jobId. Returns status + signed download URL when done.

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

Quota

Every tool response includes _meta.quota = {used, cap, tier, resetAt}. When quota drops below 20% or hits zero, the response also includes _meta.upgradeUrl and a nudge message in the text content.

Environment

Var	Purpose
`APPSCREEN_API_KEY`	Optional. MCP key (`mcm_live_…`) from https://appscreen.co/account/mcp-keys. Free tier OK. 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).
