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.

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 | $0.00088 | $0.01058 |
| Opus 5 | $0.00044 | $0.00529 |
| Sonnet 5 | $0.00018 | $0.00212 |
| Haiku 4.5 | $0.00009 | $0.00106 |
Grade A, and why
yandex-connector scanned grade A with 0 findings 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 12d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
91% identical to yandex-connector — 35 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Yandex Market Connector
Read Yandex Market via yandex_* tools. No credentials, no browser: the data comes
from the server-rendered page state.
Yandex Market aggregates many sellers per product, which makes it the best single source for "what does this actually cost right now" — and it lists categories (appliances, electronics, groceries) that Wildberries and Ozon cover unevenly.
When to use
- Price check across competing sellers for one product
- Rating analysis, especially the star distribution — a 4.8 average with a 1-star cluster tells a very different story than a clean 4.8
- Reading buyer reviews with pros/cons separated
- Finding products outside WB/Ozon's strong categories
Tools
yandex_search(query, page=1, limit=12)— text search. Returns products with both prices, ratings, sellers and stock.yandex_card(product_id, include_reviews=True)— full detail: prices, offer count, star breakdown, and the reviews.yandex_selfcheck()— drift canary. Run it after install and whenever results look wrong.
The price field that matters most
Every price appears twice, and the difference is not cosmetic:
price_rub— what anyone pays. Quote this one.price_with_plus— requires a paid Yandex Plus subscription, typically 25-30% lower.
Yandex's own UI leads with the subscriber price, so it is easy to quote a number
the operator cannot actually get. On a card there is also
price_before_discount_rub (the pre-discount reference) and discount_percent.
Workflow patterns
Price check:
yandex_search(query="стиральная машина узкая", limit=10)- Report
price_rub; noteprice_with_plusonly as a footnote. total_availabletells you how much else exists beyond the page.
Rating analysis (the connector's strongest use):
yandex_search(query="...")→ takeproduct_idof the candidateyandex_card(product_id=...)- Read
rating_stars—{1: 10, 2: 3, 3: 10, 4: 19, 5: 502}means 4.8 is genuinely earned; a fat 1-star bucket means the average is hiding something. - Read

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.
