Rakuten MCP server

rakuten-mcp

A Model Context Protocol server for the Rakuten Web Service API. 28 read-only tools across six Rakuten product families: Ichiba (marketplace), Books, Travel, Recipe, Kobo, and GORA (golf).

Every tool description ships in English and Japanese. Every endpoint was verified against the live Rakuten API on 2026-06-04 before release.

Install

npm install -g rakuten-mcp

Or npx rakuten-mcp on demand.

Configuration

1. Register at Rakuten Web Service.
2. Create an application. You get a UUID Application ID and a pk_-prefixed Access Key.
3. Optional: register an Affiliate ID to monetize product links. Item URLs in tool responses will carry it.
