Overview

AI-generated overview

Local MCP server giving assistants access to Japanese market data scrapers covering Mercari, Rakuten, Yahoo Auctions, real estate and more.

What you can do
  • Search and compare prices across Japanese marketplaces such as Mercari, Rakuten, Yahoo Auctions, Suumo and Kakaku
  • Retrieve listings, prices and sold data from Japanese resale, hobby, camera, watch, car and property sources
  • Look up Japanese reference data such as corporate numbers, laws, medical data, weather, fuel and electricity prices
  • Return structured JSON records with title, price, currency, URL, seller, condition, images and scrape timestamp
When to use it
Useful when an assistant needs Japanese marketplace or resale pricing, cross-shop price comparison, or Japanese public and economic reference data that English-language tools usually do not cover.
Requirements
Runs as a local process on the user's machine (desktop only, stdio transport); the README suggests installing the npm package globally. The underlying Apify actors are pay-per-use, so an Apify account and its credentials are likely needed, though none are declared in the manifest.
Before you install
The README states the actors are pay-per-use with pricing shown per run, so usage can incur charges. Data is collected by scraping third-party marketplaces, so results may be incomplete or subject to those sites' terms. No credentials are declared in the manifest, but the Apify-backed actors may require an account token.

Installation

In SourceWeft

  1. Open Japan Market Data in the dashboard and add it to a workspace.
  2. 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.

Japan Market Data — Apify Store Actor Directory

Production-grade Apify Store actors powering Japanese e-commerce and market data collection. Built with a production data-collection pipeline maintaining a 38-day daily streak.

Total actors: 55 | Lifetime runs: 4,894 | All free to run (PPE)

Why Japan Market Data?

Japan is the world's third-largest economy and home to unique markets that English-language tools ignore:

  • Mercari Japan — 231K monthly active users, 5M+ daily listings
  • Yahoo! Auctions Japan — 15M+ items, the largest auction platform in Japan
  • Rakuten Ichiba — Japan's Amazon equivalent, ¥2T+ annual GMV
  • DLsite — 1M+ doujin/indie titles, the world's largest Japanese indie content marketplace
  • Mandarake — 130+ physical stores, global anime collectibles leader
  • MLIT — Official government real estate transaction data (the only MLS-style source in Japan)

Most AI agents have zero access to these data sources. This project closes that gap.

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
