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 | $0.00092 | $0.00958 |
| Opus 5 | $0.00046 | $0.00479 |
| Sonnet 5 | $0.00018 | $0.00192 |
| Haiku 4.5 | $0.00009 | $0.00096 |
Grade A, and why
avito-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 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.
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.

How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Avito Connector
Reads Avito via the internal js/items JSON API. Two tiers: impersonated HTTPS
(curl_cffi) works from a residential Russian IP; from a datacenter the firewall
answers 403 + captcha, so the fetch falls back to the operator's logged-in
Chrome over CDP — same pattern as Ozon.
When to use
- Search classifieds by text, with optional category/location filters
- One listing's price, description, views
- Seller reputation — Avito is classifieds: no per-item reviews, the seller's rating and active-listing count ARE the review signal
Tools available
avito_search(query, page, location_id, category_id)— listings via js/items. price_rub is None for ads with no price (free/exchange) — never 0.avito_card(item_id_or_url)— one listing: price, description, views, selleravito_seller(seller_id_or_url)— seller rating, review count, active listings
Not an MCP tool: avito_selfcheck() is a tri-state drift canary. It is
CLI-only — marketplace-mcp doctor runs every connector's canary at once.
What a search row does and does not carry
Confirmed against a real js/items response captured 2026-07-28 from a
residential session:
locationis an object upstream, not a string:{"id": 637640, "name": "Москва", ...}. The connector reduces it to the place name. When Avito itself has no place name for an ad, the field isNone— the numericlocationIdis deliberately NOT resolved to a city, because that would need a lookup table this connector does not have and the result would be a guess that reads like data.pricedoes not exist as a top-level key. The amount lives inpriceDetailed.value; the connector reads it and leavesNonefor priceless ads.posted_atis ISO-8601 UTC, converted from Avito'ssortTimeStamp(epoch milliseconds). There is no date string in the payload to pass through.seller_nameisNoneon search rows. The payload has no seller object at all — only a logo link. Useavito_cardoravito_sellerwhen you need the seller; do not infer a name from the search row.
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.
