🎯 核心功能

• 真实 GUI 控制：通过 Stata Automation COM 在已打开的 Stata GUI 窗口中直接运行命令

• Session 会话管理：按 do 文件路径或自定义 session_id 维护独立的 Stata 窗口，同一任务复用同一窗口

• 多窗口支持：不同 do 文件/session_id 自动创建不同 Stata 窗口，方便同时监控多个分析任务

• 灵活命令执行：支持无路径命令自动发送到最近会话，也支持在指定 session 中执行

• 完整 Do 文件管理：写入、读取、追加、运行 do 文件，支持项目本地存储

• 结构化数据获取：读取数据描述、缺失摘要、样本预览、变量标签等，辅助 Claude 精准修改分析代码

• Log 读取与解析：支持读取 Stata text log，可选输出为完整文本、简洁格式或 JSON 命令-结果对

• 安全防护：内置危险命令黑名单，防止意外删除文件或执行 shell 命令

• 任务追踪：本地记录 session、do 文件和 log 的关系，支持任务级别的复现

🔧 环境要求

📥 安装步骤

1. 克隆或下载项目

推荐放在 Stata 安装目录下的 mcp 文件夹：

# 方式一：克隆到 Stata 目录
cd D:\Stata18
git clone https://github.com/shichengg/stata-mcp mcp

# 方式二：手动下载并解压
# 下载 ZIP 后解压到 D:\Stata18\mcp

高级用户也可放在任意稳定目录，但后续 Claude Code 配置需指向实际 stata_mcp.py 路径。

2. 安装 Python 依赖

推荐方案（使用虚拟环境）：

cd D:\Stata18\mcp
python -m venv .venv
.\.venv\Scripts\Activate.ps1
pip install mcp pywin32

快速方案（全局安装）：

pip install mcp pywin32

3. 注册 Stata Automation COM

必须以 管理员身份 运行 PowerShell，执行：

Start-Process -FilePath "D:\Stata18\StataMP-64.exe" -ArgumentList "/Register" -Wait

⚠️ 注意：

• 替换 D:\Stata18\StataMP-64.exe 为你的 Stata 安装路径

• 不要在 Git Bash 中运行此命令，因为 Git Bash 可能改写 /Register

• Windows 7/8 用户可能需要禁用 UAC 或使用 runas 命令

4. 验证 COM 接口可用

运行以下命令验证 Stata Automation 是否已正确注册：

python -c "import win32com.client; s = win32com.client.Dispatch('stata.StataOLEApp'); s.DoCommand('display 12345')"

预期结果：Stata GUI 打开或被连接，并在结果窗口显示 12345。

5. 配置 Claude Code

推荐方案（使用 claude mcp add 命令）：

claude mcp add stata -- python D:\Stata18\mcp\stata_mcp.py

💡 提示：如果 Stata 安装在其他路径，请相应调整为：

claude mcp add stata -- python "C:\Program Files\Stata18\mcp\stata_mcp.py"

配置后重启 Claude Code，确认工具列表中出现 stata MCP。

替代方案（手动编辑 Claude Code 配置）：

如果 claude mcp add 不可用，可手动编辑 Claude Code 的 MCP 配置文件，添加：

"stata": {
  "command": "python",
  "args": ["D:\\Stata18\\mcp\\stata_mcp.py"]
}

💡 配置文件位置：通常在 %APPDATA%\Code\User\settings.json 或通过 Claude Code 的设置界面配置

🌍 环境变量（可选）

通常用户无需设置。如果有特殊需求（如非标准安装路径），可在启动 MCP 前设置以下环境变量：

示例：

$env:STATA_DIR = "C:\Program Files\Stata18"
$env:STATA_COM_PROG_ID = "stata.StataOLEApp"
python D:\Stata18\mcp\stata_mcp.py

💡 最佳实践

快速数据探索

# 1. 加载数据
stata_run_dofile(path="D:/project/load_data.do", session_id="explore")

# 2. 查看数据结构
stata_get_data_schema(sample_rows=50)

# 3. 运行探索性分析
stata_run(commands="summarize\ncorrelation")

多步骤回归分析

# 1. 数据清洗
stata_run_dofile(path="D:/analysis/01_clean.do", session_id="proj_v1", role="source")

# 2. 主分析
stata_run_dofile(path="D:/analysis/02_model.do", session_id="proj_v1", role="entry")

# 3. 获取系数
stata_get_results(type="e")

调试和迭代

# 首次运行
stata_run_dofile(path="D:/project/analysis.do", session_id="debug_v1")

# 检查结果
stata_read_log(output_format="dict")

# 修改代码
stata_append_dofile(path="D:/project/analysis.do", content="* Fixed: ...")

# 重新运行（同一 session，append 模式）
stata_run_dofile(path="D:/project/analysis.do", session_id="debug_v1", log_mode="append")

🔍 故障排查

❌ pywin32 不可用

pip install --upgrade pywin32

❌ COM 无法创建 Stata 实例

以 管理员身份 重新注册 Stata Automation：

Start-Process -FilePath "D:\Stata18\StataMP-64.exe" -ArgumentList "/Register" -Wait

❌ stata_run 提示没有 do 文件会话

先运行一个 do 文件：

stata_run_dofile(path="D:/project/analysis.do")

之后无路径命令会发送到这个最近会话。

❌ Claude 不能看到 Stata GUI 结果

Claude 不能读取屏幕内容。使用以下方案之一：

1. 让 Stata 写 text log，然后通过 stata_read_log 读取

2. 使用 stata_get_data_schema() 读取当前数据结构快照

3. 使用 stata_get_results() 获取存储结果

💡 Best Practices

Quick Data Exploration

stata_run_dofile(path="D:/project/load_data.do", session_id="explore")
stata_get_data_schema(sample_rows=50)
stata_run(commands="summarize\ncorrelation")

Multi-Step Regression

stata_run_dofile(path="D:/analysis/01_clean.do", session_id="proj_v1", role="source")
stata_run_dofile(path="D:/analysis/02_model.do", session_id="proj_v1", role="entry")
stata_get_results(type="e")

Debug and Iterate

stata_run_dofile(path="D:/project/analysis.do", session_id="debug_v1")
stata_read_log(output_format="dict")
stata_append_dofile(path="D:/project/analysis.do", content="* Fixed: ...")
stata_run_dofile(path="D:/project/analysis.do", session_id="debug_v1", log_mode="append")

🔍 Troubleshooting

❌ pywin32 not available

pip install --upgrade pywin32

❌ Stata COM fails to initialize

Re-register Stata Automation as Administrator:

Start-Process -FilePath "D:\Stata18\StataMP-64.exe" -ArgumentList "/Register" -Wait

❌ "No do file session" error

Run a do file first:

stata_run_dofile(path="D:/project/analysis.do")

❌ Claude can't see Stata results

Use stata_read_log() or stata_get_data_schema():

stata_read_log(output_format="dict")
stata_get_data_schema()

🤝 Contributing

Contributions welcome! Please open issues and pull requests on GitHub.

Repository: github.com/shichengg/stata-mcp

Expected result: the Stata GUI opens or is connected, and displays 12345.

Add to Claude Code (recommended)

Use claude mcp add:

claude mcp add stata -- python D:\Stata18\mcp\stata_mcp.py

If you installed the project somewhere else, replace the path with your actual path. Example:

claude mcp add stata -- python "C:\Program Files\Stata18\mcp\stata_mcp.py"

Restart Claude Code after adding the MCP server, then confirm that the stata tools are available.

Manual Claude Code MCP configuration

If you do not use claude mcp add, you can configure MCP manually with JSON:

"stata": {
  "command": "python",
  "args": ["D:\\Stata18\\mcp\\stata_mcp.py"]
}

You can also point directly to the main server file:

"stata": {
  "command": "python",
  "args": ["D:\\Stata18\\mcp\\src\\stata_mcp\\server.py"]
}

The compatibility launcher stata_mcp.py is usually recommended because it keeps your Claude Code configuration stable if the internal project layout changes later.

Environment variables

Most users do not need these. If your installation path or COM ProgID is unusual, you can configure:

Tools

Do-file and session rules

• stata_run_dofile(path) uses the absolute do-file path as the session key.

• The same do-file path reuses the same Stata window.

• Different do-file paths create different Stata windows.

• stata_run, stata_get_results, stata_get_data_info, and stata_get_data_schema are sent to the most recent do-file session by default.

• If no do file has been run yet, pathless commands will ask you to run a do file first.

Reading current data structure and sample rows

stata_get_data_schema creates a text log snapshot in the most recent do-file session and returns it to Claude. By default, it includes:

• describe

• codebook, compact

• misstable summarize

• list in 1/20, abbreviate(20)

• notes

• label dir

Options:

This lets Claude see not only variable names, types, and labels, but also a small real-data sample, which helps it write better Stata code.

Log strategy

• stata_get_data_schema overwrites its own schema snapshot log because it represents the current data state.

• For other analysis output, ask Stata to write a text log, then use stata_read_log to read it.

• Recommended rule: append within the same Claude/MCP session; overwrite the first time the same do file is run in a new session, so logs do not grow forever.

Troubleshooting

pywin32 is unavailable

Run:

pip install pywin32

COM cannot create a Stata instance

Register Stata Automation again:

Start-Process -FilePath "D:\Stata18\StataMP-64.exe" -ArgumentList "/Register" -Wait

Do not run the /Register command directly in Git Bash, because Git Bash may rewrite /Register as a path.

stata_run says there is no do-file session

Run a do file first:

stata_run_dofile(path="D:/Stata18/mcp/examples/browse_test.do")

After that, pathless commands are sent to the most recent session.

Claude cannot directly see Stata GUI output

Claude cannot read screen contents directly. To let Claude analyze Stata output, write a Stata text log and read it with stata_read_log; or use stata_get_data_schema for a current data snapshot.
