Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00098 | $0.00869 |
| Opus 5 | $0.00049 | $0.00434 |
| Sonnet 5 | $0.00020 | $0.00174 |
| Haiku 4.5 | $0.00010 | $0.00087 |
Grade A, and why
ozon-connector scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
When to use
- Product detail: price, rating, seller, characteristics
- Search Ozon catalog
- Cross-check Ozon vs WB prices
Tools available
ozon_card(sku_or_path)— fetch full product card via composer-api.bxozon_search(query, page)— search Ozon catalog;pageis 1..10, one page per callozon_reviews(sku_or_path, limit, sort)— product reviews
Not an MCP tool: ozon_selfcheck() is a drift canary: success means both
tiers answered, inconclusive means Chrome was unreachable, drift_detected
means the payload shape moved. It is CLI-only — marketplace-mcp doctor runs
every connector's canary at once.
Workflow
ozon_search("query")→ get list of SKUsozon_card(sku)→ drill into chosen product- If a call comes back blocked, the tier-1 request was challenged — start Chrome
for the fallback (
scripts/start_chrome_cdp.ps1), log into ozon.ru in the scraping profile, and retry. Confirm the port withTest-NetConnection 127.0.0.1 -Port 9222.
Gotchas
- Ozon sometimes shows captcha challenge. Library waits 5s but cannot solve captcha.
If
status=error type=parse, open ozon.ru manually, solve captcha, retry. - ETOZ TLS fingerprint check is why we use CDP. Do NOT try curl/httpx directly.
- Composer-api widget keys vary (webPrice-XXXX). Library scans all webPrice-* keys.
- A missing price is
null, never0:price: null(andcard_price: null) means Ozon served no usable price — treat it as no data, never as a free item.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
