Japan Used Market — MCP server (cameras, watches, guitars, model trains)

[CI] [npm]

An MCP server that lets Claude and other MCP clients search, price and watch Japan's used camera, watch, musical-instrument and model-train shops. Every tool takes a market: "camera" (default), "watch", "instrument" or "model-train".

Grades are normalized across shops, and every shop's own label is kept as well. Prices come in JPY and USD. Watches also carry the reference number (e.g. SBGA211, 16233). Instruments carry the model code (ST57-70TX, JB62-58), country of manufacture (madeIn; Fender is split into Fender Japan / USA / Mexico), production year / era, case and the Reverb condition name. Model trains carry the maker's product code (KATO 10-1332, TOMIX 98313, MicroAce A-6590), scale (N / HO / Z), set type (set / add-on / single), whether a powered car is included, case / manual / sleeve and the lot year.

It runs the Japan Used Camera Market and Japan Used Watch Market, Japan Used Guitar & Instrument Market and Japan Used Model Train Market Actors on Apify with your own Apify token, so runs are billed to your Apify account. That is pay per result, and the free plan's monthly credit covers light use.

Renamed from @keiya-dev/japan-used-camera-mcp. The old package still works (it now just starts this one), and calls without market behave exactly as in 0.2.0. Switch the package name in your config when convenient.

Install

You need Node.js 20+ and an Apify API token: Apify Console → Settings → API & Integrations.

search_listingsCurrent listings matching keywords / brands / grades / minPriceJpy / maxPriceJpy from the selected sources. Returns shop, title, brand, model key, normalized + raw grade, JPY, USD, stock flag and URL; watches add ref, gender and accessories (e.g. box + warranty card; WATCHNIAN, GINZA RASIN and Jackroad); instruments add ref, type, madeIn, year, era, case, reverbCondition and store; model trains add productCode, scale, setType, motorized, accessories, lotYear and store. maxItems 1–200 (default 20).15–60 s
price_statsPer-model summary of in-stock listings right now: count, min / median / max (JPY and USD) by shop and by grade, cheapest listing. maxItems = listings read first (default 300; 0 = everything, ~25 min with all shops).1–4 min
price_historyDaily min / median / max / count per model, by shop, grade and shop × grade, for the last days (default 90). Reads stored snapshots (since 2026-11-05: daily for Fujiya, Sanpou, Naniwa, WATCHNIAN, GINZA RASIN, Jackroad, Shimokura, Ishibashi, Shimamura, Ikebe and Hobbyland Pochi; weekly on Sundays for J-Guitar and Hard Off), so there is no crawling.

start_monitorCreates, in your Apify account, a saved Task in monitor mode plus a Schedule (default hourly, cron, timezone) and starts the first run (baseline). Later runs emit only NEW / PRICE_DROP / PRICE_UP / SOLD_OUT, optionally POSTed to alertWebhookUrl (Slack, Discord, n8n…). Your client should confirm with you first; delete the Task/Schedule in Apify Console when done.~1 min to set up

sources and grades must belong to the chosen market (default: all of its shops). A mismatch, e.g. market: "watch" with sources: ["fujiya"], returns an error naming the valid values without starting a run. Monitors are named jucm-monitor-<name> (camera), juwm-monitor-<name> (watch), juim-monitor-<name> (instrument) or jutm-monitor-<name> (model-train) in your Apify account.

start_monitor

Start a change monitor (scheduled)

Creates, in the user's own Apify account, a saved Task running the market's Actor in monitor mode and a Schedule for it (hourly by default), then starts the first run to record the baseline. Later runs emit only changes (NEW / PRICE_DROP / PRICE_UP / SOLD_OUT) and can POST them to a Slack / Discord / n8n webhook. This creates resources and recurring runs that use the user's Apify credit — confirm with the user first.
