Ozon Connector

Two-tier connector. Tier 1 is curl_cffi with TLS impersonation and handles most queries — no browser involved. Only when Cloudflare serves a JS challenge does the fetch fall back to tier 2, inside the operator's logged-in Chrome over the DevTools Protocol. Plain curl/httpx fails outright (307 loop on the TLS fingerprint), which is why tier 1 impersonates and tier 2 exists at all.

Prerequisite

Nothing to set up for tier 1. For the tier-2 fallback, Chrome is started on first use by mcp_core.transport.chrome_cdp if the CDP port is not already listening, into a dedicated %LOCALAPPDATA%\Chrome-Scraping profile. From a Russian residential IP tier 1 usually answers and Chrome is never touched.
