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 | $0.00584 | $0.00584 |
| Opus 5 | $0.00292 | $0.00292 |
| Sonnet 5 | $0.00117 | $0.00117 |
| Haiku 4.5 | $0.00058 | $0.00058 |
Grade A, and why
t-invest-mcp-server CLAUDE.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 10d 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 — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — T-Invest MCP Server
Принципы разработки
1. Безопасность — приоритет №1
- Торговые операции необратимы. Подтверждение сделок делегировано MCP-клиенту (Claude Desktop и др.).
- Никаких секретов в коде. Токен API и URL передаются только через переменные окружения. Никогда не логировать токен, accountId или финансовые данные в stderr/stdout вне MCP-ответов.
- Валидация входных данных. Все параметры инструментов валидируются через Zod до обращения к API. Никакой прямой передачи пользовательских строк в URL или заголовки без санитизации.
- Минимальные права. Инструмент запрашивает у API ровно то, что нужно для ответа — без избыточных данных.
- Ошибки API не раскрывают внутренние детали. Сообщения об ошибках возвращаются пользователю как есть из API, но не включают токен или другие credentials.
2. Качество кода
- TypeScript strict mode, никаких
any. - Каждый инструмент в отдельном файле
src/tools/*.ts. - Форматирование ответов — на русском языке.
- Обработка ошибок в каждом инструменте через try/catch с
isError: true.
3. API-клиент
- HTTP-клиент — нативный
fetch(Node 18+), без сторонних HTTP-библиотек. - Таймаут 10 секунд на все запросы.
- Все запросы к T-Invest API — POST с JSON-телом.

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.
