Japan E-Commerce & Secondary Market Search MCP
io.github.atushi1841v0.1.0Updated Oct 6, 2026
Japanese e-commerce search MCP for AI agents. Search Mercari, Yahoo Auctions, Suruga-ya.
Overview
Lets an assistant search Japanese marketplaces such as Mercari, Yahoo Auctions and Suruga-ya for prices and stock, and get resale sourcing guidance.
- What it does
- The server exposes two tools. search_japan_marketplace takes a keyword and an optional platform (mercari, yahoo, surugaya or all) plus a result limit, and returns a query summary, the platforms searched, and results with platform, search URL, notes and a recommended actor. get_japan_resale_guidance takes a category (tcg, camera, luxury, figure or watch) and keywords, and returns market characteristics, recommended sourcing channels and pointers to related Apify actors.
- When to use it
- Useful when an assistant needs Japanese marketplace or secondary-market pricing and availability context, or resale sourcing guidance for collectibles, cameras, watches and luxury goods. It is a desktop-only local server, so it suits Claude Desktop, Cursor or VS Code style clients rather than web deployment.
- Requirements
- Runs as a local process over stdio (or optionally HTTP mode on a chosen port). Needs Python and the fastmcp package installed; the README shows pip install fastmcp and running server.py. No authentication, environment variables or headers are declared. The README notes HTTP mode is planned for 2026-10.
Installation
In SourceWeft
- Open Japan E-Commerce & Secondary Market Search MCP in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
