Token cost

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.

Security

Grade A, and why

marketplaces-mcp 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 today.

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.

Маркетплейсы через MCP

Ставит сервер marketplaces-mcp-ru: 1022 метода официальных Seller API в одном каталоге.

маркетплейс методов префикс инструментов
Ozon Seller 441 ozon_
Wildberries 307 wb_
Яндекс Маркет 165 ym_
Авито 64 avito_
Ozon Performance (реклама) 45 ozon_perf_

Каталог лежит в YAML и исполняется сервером, поэтому агент получает несколько универсальных инструментов на маркетплейс, а не по отдельной функции на каждый метод.

Установка

uvx marketplaces-mcp-ru

Конфигурация клиента (Claude Desktop, Cursor, Claude Code):

{
  "mcpServers": {
    "marketplaces-ru": {
      "command": "uvx",
      "args": ["marketplaces-mcp-ru"],
      "env": {
        "WB_API_TOKEN": "<токен Wildberries, необязательно>",
        "OZON_CLIENT_ID": "<client id Ozon, необязательно>",
        "OZON_API_KEY": "<api key Ozon, необязательно>",
        "YANDEX_MARKET_API_KEY": "<ключ Яндекс Маркета, необязательно>",
        "AVITO_CLIENT_ID": "<client id Авито, необязательно>",
        "AVITO_CLIENT_SECRET": "<client secret Авито, необязательно>"
      }
    }
  }
}

Переменные тех маркетплейсов, на которых человек не торгует, просто не указываются: сервер поднимется и будет работать с остальными.

Где взять ключи

  • Wildberries: seller.wildberries.ru, Настройки → Доступ к API.
  • Ozon: seller.ozon.ru, Настройки → API-ключи, нужны обе половины пары.
  • Яндекс Маркет: partner.market.yandex.ru, Настройки → API.
  • Авито: Для бизнеса → Интеграции → API, пара меняется на токен по OAuth2.

Второй путь, без переменных окружения: поднять сервер и вызвать <префикс>_add_cabinet. Ключи лягут в ~/.marketplace-mcp/cabinets.json с правами 600 и с машины не уходят. Так же подключается второй магазин.

Что спрашивать у сервера

  • wb_search_methods("остатки по складам"): поиск метода словами.
  • ozon_describe_method(...): параметры, пагинация, класс доступа.
  • ym_call_method(...): вызов. Чтение идёт сразу, запись просит подтверждения, необратимое просит дважды.
  • avito_check_auth: проверить, что ключи дошли.

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.
