Rakuten Japan MCP — 楽天市場商品検索

What This Does

This actor wraps the official Rakuten Ichiba Item Search API and makes it available as:

1. A traditional Apify actor — run from the Apify Console, API, or schedule
2. An MCP server — connect AI agents (Claude, Cursor, ChatGPT) to search Rakuten in real-time

Why use this? Rakuten is Japan's largest e-commerce platform with millions of products. This gives you programmatic access to product data without scraping HTML or managing proxies. 100% legal — uses the official API.

FAQ

Do I need a Rakuten API key? No. The actor uses the creator's API credentials internally. You just search.

Is this legal? Yes. This uses the official Rakuten Web Service API with proper attribution.

Can I use this from an AI agent like Claude? Yes. Connect via MCP endpoint. The server speaks Streamable HTTP at /mcp.

How many results can I get per search? Up to 100 items per query (Rakuten API limit).

Limitations

• Results are limited to what the Rakuten Ichiba Item Search API returns
