+## Technical notes
+
+### Metro
+- GraphQL API: `https://online.metro-cc.ru/api/graphql`
+- No auth needed for search
+- Fields: `search(storeId: 10, text: $q) { products(size: $n) { products { id name url prices { price } } } }`
+
+### Магнит
+- REST API: `POST https://magnit.ru/webgate/v2/goods/search`
+- Prices in kopecks — divide by 100 for rubles
+- Hardcoded `storeCode: 992301` (Moscow dostavka warehouse)
+- No auth for search; cart needs VNC login (Yandex Captcha blocks anon)
+
+### ВкусВилл
+- Search: Playwright renders `https://vkusvill.ru/search/?search_text={query}`, extracts `.js-datalayer-catalog-list` items
+- Product pages use microdata (`itemprop="price"`, `itemprop="name"`) — no JSON-LD
+- Search results mix popular items with query matches; first 6 results may not be query-specific
+- Cart/order: VNC login at `https://vkusvill.ru/personal/`
+
+### Amazon
+- Uses `amazon.de` (EU) — `amazon.com` returns 503 via this proxy
+- Playwright browser context uses system proxy `http://127.0.0.1:56928`
+- Login: VNC at `https://www.amazon.de/ap/signin`
+
+## VNC login flow
+
+```
+marketplace_open_vnc("store")    # opens browser tab at store login page
+# user connects via VNC and logs in
+marketplace_save_session("store")  # saves cookies/session to /sessions/{store}.json
+```
+
+Sessions persist across restarts (stored in container volume).
+
+## Start / stop
+
+```bash
+cd ~/agap_git/marketplace-mcp
+docker compose up -d
+docker compose restart marketplace-mcp
+docker logs marketplace-mcp-marketplace-mcp-1 -f
+```
