概覽

AI 產生的概覽

透過 Apify Actor 搜尋、比價並追蹤日本二手相機店的相機與鏡頭商品，需自備 Apify 權杖。

可以做什麼
  • 依關鍵字、品牌、品相等級與價格區間，搜尋 Fujiya、Sanpou、Naniwa 與 Hard Off 目前的二手相機與鏡頭商品
  • 依機型彙整目前上架價格，提供數量與最低、中位、最高價（日圓與美元），並依店家與統一品相等級細分
  • 從已儲存的快照讀取依機型、店家與品相劃分的每日價格歷史，可指定天數
  • 在 Apify 帳號中建立監控任務與排程，只回報新上架、降價、漲價或售完的商品，並可選擇推送到 webhook
適用情境
適合在日本二手市場挑選或比較相機與鏡頭、判斷某個價格是否合理，或追蹤某機型中位價隨時間的變化。也適合設定新上架或降價的定期提醒。
執行需求
需要 Node.js 20+ 與本機 stdio 用戶端（如 Claude Desktop、Claude Code、Cursor），也可選用本機連接埠的 HTTP 模式。需要 Apify API 權杖，透過 APIFY_TOKEN 環境變數提供（HTTP 模式下也可每次請求以 Bearer 權杖傳送），並能連線至 Apify 與各店家的公開頁面。
安裝前請注意
每次呼叫都會在你自己的 Apify 帳號上執行 Actor，依結果計費，搜尋與統計會消耗額度。start_monitor 會在你的 Apify 帳號中建立任務與排程並啟動一次執行，用完後需在 Apify 主控台刪除。你提供的 webhook 網址會收到提醒推送。價格為含稅標價而非成交價，且此服務與各店家並無關聯。

安裝

README

Japan Used Camera Market — MCP server

[CI] [npm]

An MCP server that lets Claude and other MCP clients search, price and watch Japan's used camera shops:

  • Fujiya Camera (Nakano): full used stock, ~3,500 listings
  • Sanpou Camera (Jiyugaoka): full used stock, ~1,300 listings
  • Naniwa / Lemon-sha / Takachiho: new arrivals only, ~200–300
  • Hard Off Off Mall (nationwide): cameras and lenses on sale, ~16,000

Condition grades are normalized across shops (NEW > A > AB+ > AB > AB- > B > ASIS > PARTS), and every shop's own label is kept as well. Prices come in JPY and USD.

It runs the Japan Used Camera Market Actor 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.

Install

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

Claude Desktop

Edit claude_desktop_config.json:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
json
{  "mcpServers": {    "japan-used-camera": {      "command": "npx",      "args": ["-y", "@keiya-dev/japan-used-camera-mcp"],      "env": { "APIFY_TOKEN": "apify_api_..." }    }  }}

Restart Claude Desktop. The four tools appear under the 🔨 icon.

Claude Code

bash
claude mcp add japan-used-camera -e APIFY_TOKEN=apify_api_... -- npx -y @keiya-dev/japan-used-camera-mcp

Cursor / other stdio clients

Command npx, args ["-y", "@keiya-dev/japan-used-camera-mcp"], env APIFY_TOKEN.

Streamable HTTP

bash
APIFY_TOKEN=apify_api_... npx -y @keiya-dev/japan-used-camera-mcp --http --port 3000
  • Endpoint http://localhost:3000/mcp; health check /health.
  • Each request may send its own token as Authorization: Bearer <APIFY_TOKEN>; otherwise the server's APIFY_TOKEN is used.
  • The server is stateless (POST only, JSON responses).

Tools

ToolWhat it doesTypical time
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. 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 daily snapshots (Fujiya, Sanpou, Naniwa; since 2026-11-05), so there is no crawling. Needs keywords, brands or models (model keys from price_stats).seconds
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 (all tools): fujiya, sanpou, naniwa, hardoff. All four by default.

Example prompts

  • "What's the cheapest AB-or-better Leica M6 in Japanese shops right now?"
  • "Compare Nikon Zf prices by shop and grade."
  • "How has the median Fujifilm X100VI price moved over the last 30 days?"
  • "Watch for new Voigtländer lenses under ¥80,000 and post them to my Slack webhook https://hooks.slack.com/services/…"

Develop

bash
npm installnpm test            # tsc build + end-to-end tests (stdio, HTTP, missing token) against a fake Apify APInpm run start       # stdionpm run start:http  # HTTP on :3000

APIFY_API_BASE_URL overrides the Apify API base URL (used by the tests).

Notes

  • Not affiliated with any of the shops. Prices are the shops' tax-included asking prices, not sold prices.
  • Data comes from the shops' public listing pages only. Product pages, serial numbers and condition notes are not read.
  • The Actor's README covers coverage, limits and pricing: https://apify.com/keiya_dev/japan-used-camera-market

price_history

Daily price history per model

Daily min / median / max / count per model, by shop and condition grade, from stored daily snapshots of the shops (Fujiya, Sanpou and Naniwa; collected since 2026-11-05, so the first month is short). No crawling — returns in seconds. Needs keywords, brands or models.

start_monitor

Start a change monitor (scheduled)

Creates, in the user's own Apify account, a saved Task running this 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.
