ASO MCP Server

A Model Context Protocol (MCP) server for App Store Optimization (ASO) research in Google Play Store.

Please note: This MCP is a very early feature-limited prototype and is not yet ready for production use.

Built on top of google-play-scraper - a Python library for scraping Google Play Store data.

Features

  • App Search - Search for apps by keyword with price filtering
  • App Details - Get comprehensive information about any app
  • App Reviews - Fetch user reviews with sorting, filtering, and pagination
  • Collections & Categories - Browse top free, top paid, and grossing apps by category
  • Keywords Research - Get keyword suggestions from Google Play Store autocomplete
  • Metadata Validation - Validate titles, short descriptions, and full descriptions against Google Play limits
  • Country & Language Support - Access all Google Play supported countries and languages
  • Proxy Rotation - Optional proxy support with automatic rotation and retry on failure

Proxy Configuration

The server supports optional proxy rotation for requests to Google Play. This is useful for:

  • Avoiding rate limiting
  • Geographic distribution of requests
  • IP rotation

Setup

Set the ASO_MCP_PROXIES environment variable with a comma-separated list of proxy URLs:

export ASO_MCP_PROXIES="http://proxy1:8080,http://proxy2:8080,http://user:pass@proxy3:8080"

With Claude Code

{
  "mcpServers": {
    "aso": {
      "command": "uv",
      "args": [
        "run",
        "python",
        "server.py"
      ],
      "cwd": "/path/to/aso-mcp-python",
      "env": {
        "ASO_MCP_PROXIES": "http://proxy1:8080,http://proxy2:8080"
      }
    }
  }
}

With Gemini CLI

{
  "mcpServers": {
    "aso": {
      "command": "uv",
      "args": [
        "run",
        "python",
        "server.py"
      ],
      "cwd": "/path/to/aso-mcp-python",
      "env": {
        "ASO_MCP_PROXIES": "http://proxy1:8080,http://proxy2:8080"
      }
    }
  }
}

How Proxy Rotation Works

  1. On each request, a random proxy is selected from the pool
  2. If a request fails, the proxy is marked as failed and a different proxy is tried
  3. Failed proxies are avoided until all proxies have failed
  4. When all proxies fail, the failed list resets and rotation starts over
  5. Credentials in proxy URLs are masked in logs for security

Supported Proxy Formats

http://host:port
http://username:password@host:port
https://host:port
https://username:password@host:port

Google Play Metadata Limits

| Field | Character Limit | |-------------------|-----------------| | Title | 30 | | Short Description | 80 | | Full Description | 4000 |
