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

YooKassa-MCP AGENTS.md 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 8d 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.

Назначение проекта

Этот репозиторий предназначен для разработки российского аналога официального Stripe-плагина для ИИ-агентов на базе ЮKassa.

Целевой продукт должен позволять агентным средам, включая ChatGPT, Codex и другие MCP-совместимые клиенты:

  • находить актуальную информацию в документации ЮKassa;
  • подбирать безопасный сценарий интеграции;
  • читать разрешенные данные магазина и платежных объектов;
  • выполнять явно разрешенные операции через API ЮKassa;
  • создавать и использовать специализированные skills;
  • соблюдать требования безопасности платежных интеграций и применимые требования 54-ФЗ.

Stripe используется как архитектурный и продуктовый ориентир. Нельзя переносить из Stripe платежную семантику, параметры API, налоговые правила или юридические выводы, если они не подтверждены документацией ЮKassa и российскими нормативными источниками.

Текущий MVP для Codex

Текущая версия — устанавливаемый локальный Codex-плагин для технической интеграции, а не агент управления деньгами.

  • Пять skills: integration-planner, implementation, receipts-54fz, diagnostics, integration-review.
  • MCP работает только через stdio.
  • MCP предоставляет документацию, каталог API, офлайн-валидацию, объяснение ошибок и read-only диагностику тестового магазина.
  • В MCP запрещены POST, PUT, PATCH и DELETE. Платежи, capture, cancel, refunds, receipts и webhook-настройки он не изменяет.
  • Код write-интеграции создается в проекте пользователя и выполняется самим приложением с тестовыми реквизитами.
  • Живая диагностика разрешена только после подтверждения payment.test === true.
  • При payment.test === false производственные данные не возвращаются, а MCP блокируется до перезапуска.
  • Расширение на боевые или финансовые операции требует отдельной версии, policy-слоя, human confirmation, аудита и новой модели угроз.

Эти ограничения текущего MVP имеют приоритет над более общей целевой архитектурой ниже.

Язык работы

  • Общение с пользователем, проектная документация и пояснения должны быть на русском языке.
  • Имена программных сущностей, MCP-инструментов, функций, классов и файлов могут быть на английском, если это соответствует принятому стеку.
  • Тексты ошибок для пользователя должны быть понятными на русском; внутренние коды ошибок должны быть стабильными и машиночитаемыми.

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.
