t-invest-mcp: Instructions file for Codex

AGENTS.md

t-invest-mcp AGENTS.md is an instructions file for Codex, OpenCode from human-turn/t-invest-mcp. It costs 1,857 tokens per session, scanned A, original, Apache-2.0.

AGENTS.md instructions for developing and checking a TypeScript MCP server connected to T-Invest, the Tinkoff Investments API. They document the project structure, safety rules, build commands, and available modes.

In plain words
What is it for?
Building the server, running its development version, performing a JSON-RPC smoke test, and understanding which tools appear in read-only, trading, or sandbox modes.
Why use it?
They give coding agents the repository rules and testing steps needed to change the server without weakening its trading safeguards.

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

t-invest-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 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.

AGENTS.md — инструкции для AI-агентов

MCP-сервер (TypeScript, stdio) для T-Invest API (Т-Инвестиции). Агент, работающий с этим репо, обязан соблюдать инварианты безопасности — они важнее любых фич.

Сборка и проверка

npm install
npm run build        # tsc, strict mode — должен проходить без ошибок
npm run dev          # запуск из исходников (tsx)

Unit-тестов пока нет. Смоук-тест — JSON-RPC по stdio (без реального токена сервер стартует и отдаёт списки):

(printf '%s\n' \
  '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"smoke","version":"0"}}}' \
  '{"jsonrpc":"2.0","method":"notifications/initialized"}' \
  '{"jsonrpc":"2.0","id":2,"method":"tools/list"}'; sleep 2) \
  | TINKOFF_API_TOKEN=fake node dist/index.js

Ожидаемо: 20 tools без флагов (16 read из read.ts + 3 архивных из bulk.ts + get_server_info); с TINKOFF_ALLOW_TRADING=true +2, с TINKOFF_SANDBOX=true +3. Prompts: 15. Реальные проверки — только с sandbox-токеном.

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.
