CLAUDE.md

shioaji-mcp CLAUDE.md is an instructions file for Claude Code from offbeat-studio/shioaji-mcp. It costs 1,617 tokens per session, scanned A, original, MIT.

A project instruction file for Claude Code, describing a Shioaji MCP server that connects to Taiwan’s SinoPac Securities trading API and market data. It also records the project’s tools, setup, testing, security rules, and task process.

In plain words
What is it for?
Use it when developing, testing, packaging, or deploying this Python trading MCP server. It covers task tracking, code checks, type checks, tests, Docker, GitHub Actions, commit format, and mock-based trading API tests.
Why use it?
It gives the coding agent the project context and working rules it needs, so development choices remain consistent with the repository. It also documents safeguards such as keeping trading disabled by default and storing secrets in environment variables.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: names the TodoWrite tool; mentions Claude Code.

This is offbeat-studio/shioaji-mcp's own configuration. It tells Claude Code how to work on shioaji-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything shioaji-mcp configures →

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

shioaji-mcp 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 6d 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.

Shioaji MCP Server - Claude Code 專案配置

專案概述

Shioaji MCP Server 是一個提供永豐金證券交易 API 功能的模型上下文協議 (MCP) 伺服器。專案已達到生產就緒狀態,支援完整的交易操作和市場資料存取功能。

任務管理系統

配置狀態: 使用本地 markdown 檔案進行任務管理

  • 系統類型: Claude Code 內建 TodoWrite 工具
  • 任務追蹤: 透過對話中的 todo list 進行即時追蹤
  • 狀態同步: 任務狀態會在每次更新時同步顯示

技術棧和工具

開發環境

  • Python: 3.10-3.12
  • 套件管理: uv (優先選擇)
  • MCP 框架: mcp>=1.0.0
  • 交易 API: shioaji==1.2.5

程式碼品質工具

  • 代碼檢查: ruff (取代 black, isort, flake8)
  • 型別檢查: mypy
  • 測試框架: pytest with pytest-asyncio

部署和分發

  • 容器化: Docker with multi-platform support
  • 容器註冊表: GitHub Container Registry (ghcr.io)
  • CI/CD: GitHub Actions

開發工作流程

代碼提交規範

  • 使用 conventional commits 格式: <type>[optional scope]: <description>
  • 例如: feat(trading): add order cancellation functionality
  • 例如: fix(auth): resolve connection timeout issues

測試要求

  • 所有新功能必須包含對應的單元測試
  • 測試覆蓋率應保持在合理水平
  • 使用 mock 進行 API 相關測試以避免真實交易

安全考量

  • 交易安全: 交易功能預設關閉,需要明確啟用 SHIOAJI_TRADING_ENABLED=true
  • 憑證管理: 所有敏感資訊透過環境變數管理
  • 權限控制: 實施分層權限管理系統

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.
