💡 Quick Start

Use Stata-MCP in Claude Code

We can use Stata-MCP in Claude Code as its prefect agentic ability.

Before using it, please make sure you have ever install Claude Code, if you don't know how to install it, visit on GitHub

You can open your terminal and cd to your working directory, and run:

claude mcp add stata-mcp --env STATA_MCP_CWD=$(pwd) -- uvx stata-mcp

I am not sure whether it works on Windows, as I do not have a Windows device for test it.

Then, you can use Stata-MCP in Claude Code. Here are some scenarios for using it:

• Paper Replication: Replicate empirical studies from economics papers
• Quick Hypothesis Testing: Validate economic hypotheses through regression analysis
• Stata Learning Assistant: Learn econometrics with step-by-step Stata explanations
• Code Organization: Review and optimize existing Stata do-files
• Result Interpretation: Understand complex statistical outputs and regression results

Agent Mode

The details of agent mode find here.

git clone https://github.com/sepinetam/stata-mcp.git
cd stata-mcp

uv sync
uv pip install -e .

stata-mcp --version  # for test whether stata-mcp is installed successfully.
stata-mcp --agent  # now you have enjoy your stata-mcp agent mode.

or you can directly use it with uvx:

uvx stata-mcp --version  # for test whether it could be used on your computer.
uvx stata-mcp --agent

You can edit the task in agent_examples/openai/main.py for variable model_instructions and task_message, click me #L37 and #L68

Agent as Tool

If you want to use a Stata-Agent in another agent, here is a simple example:

import asyncio

from agents import Agent, Runner
from stata_mcp.agent_as_tool import StataAgent

# init stata agent and set as tool
stata_agent = StataAgent()
sa_tool = stata_agent.as_tool()

# Create main Agent
agent = Agent(
    name="Assistant",
    instructions="You are a helpful assistant", 
    tools=[sa_tool],
)

# Then run the agent as usual.
async def main(task: str, max_turns: int = 30):
    result = await Runner.run(agent, input=task, max_turns=max_turns)
    return result


if __name__ == "__main__":
    econ_task = "Use Stata default data to find out the relationship between mpg and price."
    asyncio.run(main(econ_task))

AI Chat-Bot Client Mode

Standard config requires: please make sure the stata is installed at the default path, and the stata cli (for macOS and Linux) exists.

The standard config json as follows, you can DIY your config via add envs.

{
  "mcpServers": {
    "stata-mcp": {
      "command": "uvx",
      "args": [
        "stata-mcp"
      ]
    }
  }
}

For more detailed usage information, visit the Usage guide.

And some advanced usage, visit the Advanced guide

Prerequisites

• uv - Package installer and virtual environment manager
• Claude, Cline, ChatWise, or other LLM service
• Stata License
• Your API-KEY from LLM

Notes:

1. If you are located in China, a short uv usage document you can find here.
2. Claude is the best choice for Stata-MCP, for Chinese, I recommend to use DeepSeek as your model provider as it is cheap and powerful, also the score is highest in China provider, if you are increased in it, visit the report How to use StataMCP improve your social science research.

Installation

For the new version, you don't need to install the stata-mcp package again, you can just use the following command to check whether your computer can use stata-mcp.

uvx stata-mcp --usable
uvx stata-mcp --version

If you want to use it locally, you can install it via pip or download the source code.

Download via pip

pip install stata-mcp

Download source code and compile

git clone https://github.com/sepinetam/stata-mcp.git
cd stata-mcp

uv build

Then you can find the compiled stata-mcp binary in the dist directory. You can use it directly or add it to your PATH.

For example:

uvx /path/to/your/whl/stata_mcp-1.11.1-py3-non-any.whl  # here is the wheel file name, you can change it to your version
