App Store + Google Play Data

appstore-data-mcp

MCP server that gives Claude, Cursor, VS Code, Codex and any other MCP client live data from the Apple App Store and Google Play — app details, reviews, keyword search, top charts and category taxonomies, for 175+ country storefronts.

Powered by the App Store Google Play Data API (free tier: 500 calls/month).

Tools

Both stores are normalized to the same field names (id, name, developer, rating, …) so the model does not have to learn two schemas.

Setup

1. Get a free RapidAPI key: https://rapidapi.com/TheValkDokk/api/app-store-google-play-data-api → subscribe to BASIC → copy X-RapidAPI-Key from the code snippet.
2. Add the server to your client with RAPIDAPI_KEY in the environment.

Claude Code

# key already exported in your shell

claude mcp add appstore-data --scope user -e RAPIDAPI_KEY=$RAPIDAPI_KEY -- npx -y appstore-data-mcp

or inline the key

claude mcp add appstore-data --scope user -e RAPIDAPI_KEY= -- npx -y appstore-data-mcp

Then claude mcp list should report appstore-data: npx -y appstore-data-mcp - ✔ Connected.

A -e value written as ${SOMETHING} is resolved against Claude Code's own environment when it spawns the server, so -e 'RAPIDAPI_KEY=${RAPIDAPI_KEY}' only works if RAPIDAPI_KEY is exported in the shell that starts Claude Code. If it is not, claude mcp list warns Missing environment variables: RAPIDAPI_KEY and tool calls come back as MISSING_CREDENTIALS. The server itself starts either way — the key is only read at tool-call time.

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{

"mcpServers": { "appstore-data": { "command": "npx", "args": ["-y", "appstore-data-mcp"], "env": { "RAPIDAPI_KEY": "your-rapidapi-key" } } } }

Cursor

~/.cursor/mcp.json (global) or .cursor/mcp.json (per project) — same mcpServers block as above.

VS Code (Copilot agent mode)

.vscode/mcp.json:

{

"servers": { "appstore-data": { "command": "npx", "args": ["-y", "appstore-data-mcp"], "env": { "RAPIDAPI_KEY": "your-rapidapi-key" } } } }

Example prompts

• "Find the top 5 meditation apps in the US and compare their ratings and review counts."
• "What changed in Instagram's iOS reviews over the last 200 entries — any 1-star complaints about the new update?"
• "Which photography apps are top-grossing in Japan right now?"
• "Pull the 25 most recent reviews for com.spotify.music in the UK and summarise the complaints."

Hosted endpoint (no install)

A remote copy runs at https://appstore-mcp-623314400722.us-central1.run.app/mcp (streamable HTTP, stateless). Send your own RapidAPI key as a header — nothing is shared or stored server-side:

{

"mcpServers": { "appstore-data": { "type": "http", "url": "https://appstore-mcp-623314400722.us-central1.run.app/mcp", "headers": { "X-RapidAPI-Key": "your-rapidapi-key" } } } }

Authorization: Bearer and ?key= work too. Tools list without a key, so directory crawlers can index the server; a tool call without one returns MISSING_CREDENTIALS with the signup link.

Configuration

Quotas and cost

Calls count against your RapidAPI plan: BASIC is free (500 calls/month), paid tiers from $9.99. Each tool call is one request. limit is capped at 50 per call on purpose — a larger page can exceed an MCP client's response size limit and get truncated.

Develop

npm install

npm run build RAPIDAPI_KEY=xxx npm run smoke # 26 end-to-end checks against the live API
