What is bcs-mcp AGENTS.md?

A repository instruction file for AI agents working on a TypeScript MCP server for the BCS Trade API, a Russian investment-broker service.

Use it to guide dependency installation, strict TypeScript builds, development runs, JSON-RPC smoke tests, tool registration, and read-only versus trading-enabled configuration.

It records the project’s build checks, file structure, smoke tests, and safety rules so agents can work consistently without weakening 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.

Model	Per session	Once invoked
Fable 5.1	$0.03571	$0.03571
Opus 5.5	$0.01428	$0.01428
Sonnet 5.5	$0.00714	$0.00714
Haiku 4.5	$0.00357	$0.00357

Security

Grade A, and why

bcs-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 2mo 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 BCS Trade API (БКС Мир инвестиций). 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)

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) \
  | BCS_REFRESH_TOKEN=fake node dist/index.js

Ожидаемо: 15 tools без флагов (14 read из read.ts + get_server_info); с BCS_ALLOW_TRADING=true +3 (place/edit/cancel_order). Prompts: 10. Реальные проверки — только с живым read-only токеном.

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.
