Procurement MCP — federated search across Chinese + Australian marketplaces

Integration-only. Every source is a hosted API you call with a key — no scrapers are built here. Chinese sources via aggregators (TMAPI), Australian sources via official APIs where they exist (eBay AU) and hosted scraper-APIs where they don't (Gumtree, Facebook Marketplace).

Natural-language procurement: find me the cheapest / fastest shipped / best value <item> → normalised Offer[] ranked by landed cost, ETA and seller trust.

Identity for sign-ups: io+agent@jupiter.au (approved).

Quick start

uv sync
cp .env.example .env   # add keys
uv run mcp dev server.py          # Inspector at http://localhost:5173
uv run python server.py           # stdio — for Claude Desktop
uv run mcp install server.py      # install into Claude Desktop

Mock fallback means the server is demo-able with zero keys — search_offers returns synthetic offers and health reports mock_fallback: true.

Tools

All tools run concurrent asyncio fan-out with per-marketplace timeout (PROCUREMENT_TIMEOUT_S, default 8s) and never fail the whole search if one marketplace errors.

Deal-signal lanes (no marketplace required)

Beyond marketplaces, the federation carries deal-vetting signals:

• ozbargain / cheapies — the sites' own official RSS feeds (/deals/feed), parsed with stdlib xml.etree — no key, no ToS risk. Each offer carries community (votes ±, comments, clicks, expiry, brand, tags) parsed from the ozb:meta extension and <category> taxonomy, plus price-from-title and the affiliate goto link. The best_value trust term uses net community votes — a +5-voted deal outranks a heuristic 4.8-star seller.

• ozbargain_search — true keyword search over OzBargain via the hosted Apify actor parseforge/ozbargain-australia-scraper (reuses APIFY_TOKEN; costs Apify credits).

• ebay_sold — real eBay AU sold prices (what items actually sold for, not asking) via caffein.dev/ebay-sold-listings with ebaySite: ebay.com.au. Sold comps land in price_history — a ranking correction no official API offers.

• keepa price history — when KEEPA_API_KEY is set, amazon_au offers get a price_history block (90-day avg/min via Keepa's official API, domain 12 = amazon.com.au).

Grocery lanes — unit economics

woolworths, coles, aldi via the dromb Apify series ($0.30/1k): operation: search with unit pricing, specials and barcodes. Grocery offers carry unit_price_aud + unit + regular_price_aud — price_aud holds the effective price (special when present). The cheapest ranker sorts on unit price when available, because a $4.50 2L milk beats a $3.10 1L and item price cannot express that. Costco deliberately excluded — every store actor targets costco.com (US/USD); revisit if an AU actor appears.

search_offers gates grocery and Amazon results with a relevance filter (every query term must appear in title/brand/category) — ALDI's catalogue search fuzzes "milk" into oil and lollipops without it.

search_by_image(image_url, destination, max_results)

Sourcing by photo — reverse image search across 1688 (wholesale factories), alibaba (B2B), aliexpress (retail), global (Amazon/Walmart/eBay and thousands of retail sites). Hand it a photo from any listing and get matching supplier listings with price, MOQ, supplier name and location. Alibaba's own visual-search tech, $0.10/search.

API keys — where to sign up as io+agent@jupiter.au

Recommended primary (full Chinese width in one key)

• TMAPI — https://console.tmapi.io/user/signup → Account Center → apiToken. Covers taobao/tmall/1688/pdd/jd with item_search + item_detail. Free 200/mo, paid from ~$8/mo. Set TMAPI_TOKEN.

• AliExpress Affiliate (official, moderate barrier) — https://openservice.aliexpress.com → UAC account with io+agent@jupiter.au → join Affiliate Program → create app (1–2 day approval) → AppKey/AppSecret → set ALIEXPRESS_APP_KEY/ALIEXPRESS_APP_SECRET.

Australian

• eBay AU — https://developer.ebay.com → Create app with io+agent@jupiter.au → obtain AppID (Client ID) + CertID (Client Secret) → set EBAY_APP_ID/EBAY_CERT_ID. Server does client-credentials flow for https://api.ebay.com/identity/v1/oauth/token scope https://api.ebay.com/oauth/api_scope and calls buy/browse/v1/item_summary/search with X-EBAY-C-MARKETPLACE-ID: EBAY_AU.

• Amazon AU — Seller Central Professional + https://developer.amazonservices.com → SP-API Far East endpoint https://sellingpartnerapi-fe.amazon.com (for catalogue/pricing if you are a seller) or Product Advertising API PA-API 5.0 via AMAZON_PAAPI_* + PARTNER_TAG=jupiter-22.

Hosted scraper-APIs (you call, they run browsers)

• SociaVault — https://sociavault.com → Facebook Marketplace search + item (SOCIAVAULT_API_KEY). Supports AU lat/lng. Pay-per-request, real-time.

• Apify — https://console.apify.com/settings/integrations → APIFY_TOKEN → actor crawlerbros/gumtree-scraper for Gumtree AU (residential + Akamai bypass handled by Apify).

Optional: ELIM_API_TOKEN (https://elim.asia) and RAPIDAPI_KEY for Otcommerce JD fallback.

Behaviour and ranking

• Price normalisation — price_cny → price_aud via CNY_TO_AUD (default 0.215). Landed cost = price_aud * qty + shipping.intl_estimate_aud. qty < moq (1688) pushes to end and is flagged.

• ETA — shipping.eta_days [min, max].

• Trust — seller.rating / source_reliability (authoritative > aggregator > best_effort).

• Sorts — cheapest by landed cost, fastest by ETA, best_value composite 0.5 price + 0.25 speed + 0.25 trust.

Project layout

pyproject.toml
server.py          # FastMCP server + all integrations
.env.example
research/          # hyperresearch vault (light run procurement-mcp-51d4f3)

Database — Postgres on 10.1.1.3

When DATABASE_URL is set, the server caches federated results and logs searches in the fleet Postgres (10.1.1.3:5432, jupiter db, schema procurement per stack law). When unset it runs stateless.

# Example — set in .env
DATABASE_URL=postgresql://procurement:__SET_ME__@10.1.1.3:5432/jupiter
PROCUREMENT_PG_SCHEMA=procurement
# Apply once
psql "$DATABASE_URL" -f migrations/001_procurement_cache.sql

health() reports database.enabled / database.error without leaking secrets. Cache TTL is PROCUREMENT_CACHE_TTL_S (default 3600s). Tables: procurement.search_cache (keyed by query+marketplaces+sort+qty+ship_to) and procurement.search_log.
