App Store Scraper MCP Server

This is an MCP (Model Context Protocol) server that provides tools for searching and analyzing apps from both the Google Play Store and Apple App Store.

Perfect for ASO (App Store Search Optimization).

Built by AppReply.co. For more information, see our MCP documentation.

Installation

# Clone the repository
git clone https://github.com/appreply-co/mcp-appstore.git
cd mcp-appstore

# Install dependencies
npm install

Running the Server

npm start

This will start the server in studio mode, which is compatible with MCP clients.

Claude Code: Add to .mcp.json or your MCP config (path must be absolute; on Windows you can use forward slashes):

  "mcpServers": {
    "mcp-appstore": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-appstore/server.js"]
    }
  }
}

Or: claude mcp add --transport stdio mcp-appstore -- node /absolute/path/to/mcp-appstore/server.js

Claude Desktop: Same mcpServers entry in claude_desktop_config.json (see Claude’s docs for the file path on your OS).

Each score has a human-readable interpretation to help understand its significance.

Note: The current implementation simulates ASO scores based on keyword length and other heuristics rather than using real-time data. This approach was chosen due to compatibility issues between the aso package and current versions of the Google Play and App Store scrapers. The scores follow the same structure and interpretation guidelines as actual ASO metrics but should be considered approximations.

Connecting with MCP Clients

You can connect to this server using any MCP client. Here's an example using the MCP TypeScript SDK:

import { Client } from "@modelcontextprotocol/sdk/dist/esm/client/index.js";
import { StdioClientTransport } from "@modelcontextprotocol/sdk/dist/esm/client/stdio.js";

const transport = new StdioClientTransport({
  command: "node",
  args: ["server.js"]
});

const client = new Client(
  {
    name: "app-store-client",
    version: "1.0.0"
  },
  {
    capabilities: {
      tools: {}
    }
  }
);

await client.connect(transport);

// Call a tool
const result = await client.callTool({
  name: "search_app",
  arguments: {
    term: "spotify",
    platform: "android",
    num: 5
  }
});

console.log(JSON.parse(result.content[0].text));

Performance Considerations

• The server uses memoization to cache API responses for 10 minutes to reduce external API calls
• For large numbers of reviews or extensive keyword analysis, expect longer response times
• The server includes rate limiting protection to avoid triggering API restrictions

Dependencies

This server uses the following libraries:

• google-play-scraper
• app-store-scraper
• @modelcontextprotocol/sdk
