Steam Scout MCP

Steam market research for AI assistants — regional prices, reviews, player counts, charts and news. No API key required.

An MCP server that lets Claude, Cursor, VS Code and other MCP clients answer questions like:

• "How much does Hades II cost in the US, Germany, Japan, Korea and China — which region is cheapest in USD?"

• "Compare Stardew Valley and Terraria: price, review score and how many people are playing right now."

• "What's in the Japanese Steam top sellers today?"

• "Summarize the latest patch notes and recent Korean reviews for this game."

日本語: Steam の地域別価格・レビュー・同時接続数・ランキングを AI アシスタントから調べられる MCP サーバー（API キー不要）。 한국어: Steam 지역별 가격, 리뷰, 동시 접속자 수, 차트를 AI 어시스턴트에서 조회하는 MCP 서버 (API 키 불필요). 中文：让 AI 助手查询 Steam 各地区价格、评测、在线人数和排行榜的 MCP 服务器（无需 API 密钥）。

Features

• Zero setup: only public Steam endpoints — no Steam account or API key.

• Currency conversion with European Central Bank reference rates.

• Polite by design: responses cached for 5 minutes, limited concurrency, retries with back-off.

• All tools are read-only.

Installation

Requires Python 3.10+. The easiest way is uv:

uvx --from git+https://github.com/<your-github-username>/steam-scout-mcp steam-scout-mcp --version

Or with pip:

pip install git+https://github.com/<your-github-username>/steam-scout-mcp

Usage

Claude Desktop

Add to claude_desktop_config.json (Settings → Developer → Edit Config):

{
  "mcpServers": {
    "steam-scout": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/<your-github-username>/steam-scout-mcp", "steam-scout-mcp"]
    }
  }
}

A ready-to-copy file is in examples/claude_desktop_config.json.

Tests never touch the network: Steam and the exchange-rate service are replaced by httpx.MockTransport.

Notes

• Prices come from the Steam store for each region and may differ from checkout prices (taxes, local promotions).

• Some regions have no ECB exchange rate (e.g. TWD); those prices are listed without conversion.
