Overview

Description from the maker (original English)

Live App Store and Google Play data: app details, reviews, search, top charts for 175+ storefronts.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Search & AI memory
  • You need to fill in: RAPIDAPI_KEY, X-RapidAPI-Key

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: RAPIDAPI_KEY, X-RapidAPI-Key

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

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

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

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

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

Run this in your terminal

claude mcp add --transport http appstore-data https://appstore-mcp-623314400722.us-central1.run.app/mcp --header 'X-RapidAPI-Key: your-value'

Or run it on your computer

claude mcp add appstore-data --env RAPIDAPI_KEY=your-value -- npx -y appstore-data-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": {
    "appstore-data": {
      "url": "https://appstore-mcp-623314400722.us-central1.run.app/mcp",
      "headers": {
        "X-RapidAPI-Key": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "appstore-data": {
      "command": "npx",
      "args": [
        "-y",
        "appstore-data-mcp"
      ],
      "env": {
        "RAPIDAPI_KEY": "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": {
    "appstore-data": {
      "type": "http",
      "url": "https://appstore-mcp-623314400722.us-central1.run.app/mcp",
      "headers": {
        "X-RapidAPI-Key": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "appstore-data": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "appstore-data-mcp"
      ],
      "env": {
        "RAPIDAPI_KEY": "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 address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • RAPIDAPI_KEY secret required env
    RapidAPI key from https://rapidapi.com/TheValkDokk/api/app-store-google-play-data-api
  • X-RapidAPI-Key secret required HTTP header
    RapidAPI key from https://rapidapi.com/TheValkDokk/api/app-store-google-play-data-api

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is App Store + Google Play Data 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: RAPIDAPI_KEY, X-RapidAPI-Key

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 14 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

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

ToolWhat it does
search_appsKeyword search using the store's own relevance ranking; returns ids for the other tools
get_appFull metadata for one app — name, developer, rating, price, version, size, screenshots, store URL
get_app_reviewsPaginated reviews, newest or most-helpful first, with developer replies
top_chartsFree / paid / grossing / new charts, per country and category
list_categoriesStore category ids and names, for filters and resolving top_charts categories

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

VariableRequiredPurpose
RAPIDAPI_KEYyes (unless self-hosting)Marketplace auth: sent as X-RapidAPI-Key + X-RapidAPI-Host
APPSTORE_API_BASE_URLnoPoint at your own deployment instead of the marketplace
APPSTORE_API_HOSTnoOverride the X-RapidAPI-Host value
APPSTORE_PROXY_SECRETnoSelf-hosted origin auth (X-RapidAPI-Proxy-Secret)

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.
