MCP-for-Stata (Stata-MCP): Run Stata with Claude Code and Codex

MCP-for-Stata is an open-source MCP server and CLI that lets any AI agent you use invoke local Stata on your device for regression analysis, econometrics, paper replication, and empirical research. It provides command guards, resource monitoring, automatic log capture, and cross-platform client installation, while you retain control of your data and Stata license.

Turn Claude Code, Codex, and other AI agents into an on-demand research assistant.

Installation and Client Configuration

🚀 One-click installation for all clients!

No config, no manual JSON editing. Just one command installs MCP-for-Stata for every supported agent (Claude Code, Codex, OpenClaw, Cursor, Gemini CLI, and more):

uvx stata-mcp install --all

Supported Agents 🤖

Based on our own experience and testing, we recommend using Claude Code, Codex, and OpenClaw.

We have found that Claude and DeepSeek are the two best models across any framework.

If you don't have `uv`, see the uv installation guide to install it.

Or, use our beta install script (auto-installs `uv` if missing):

macOS / Linux:

curl -fsSL https://raw.githubusercontent.com/SepineTam/mcp-for-stata/master/scripts/install.sh | bash

Windows (PowerShell):

irm https://raw.githubusercontent.com/SepineTam/mcp-for-stata/master/scripts/install.ps1 | iex

If you don't know how to use them, download the installation scripts and double-click it in your device. `install.bat` for Windows users, and `install.command` for macOS users.

Advanced - Claude Code

As we find Claude Code is the best agent for MCP-for-Stata as its prefect agentic ability, we recommend using it, and there are lots of advanced usage following:

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

Generally, you can install MCP-for-Stata globally for one time, you can run:

claude mcp add stata-mcp --scope user -- uvx stata-mcp

Then, you do not need to watch it again.

Local and share with your partners

If you want to install it locally only for the certain workspace, you can `cd` to your working directory, and run:

claude mcp add stata-mcp --env STATA_MCP__CWD=$(pwd) --scope local -- uvx --directory $(pwd) stata-mcp

It would nothing happen, you can type `claude` and type `/mcp` to find the status.

Also, collaboration is an essential part of research. You can share your MCP config with your co-authors using:

claude mcp add stata-mcp --scope project -- uvx stata-mcp

In your working directory, you can find a file named `.mcp.json`, your mcp config will be placed here.

Then, you can use MCP-for-Stata 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

If you use Claude Code inside IDEs (either the integrated terminal or the Claude Code Extension), installing our plugin including MCP-for-Stata and Stata LSP maintained by @euglevi.

# Add the MCP-for-Stata marketplace
claude plugin marketplace add SepineTam/mcp-for-stata

# Install the plugin to local, project or user scope
claude plugin install stata-toolbox -s project

> The language server gives AI-generated Stata code better syntax awareness and completion, which improves output quality. We package the LSP in compliance with its license and give full attribution to the original author.

Advanced - Codex

We find that many researchers are using Codex as their agent, therefore we also provide instructions for Codex users.

I figure that researchers are not using Codex CLI but Codex Desktop, so we can say it is easier to config MCP-for-Stata than other agents.

You just need to say `Install MCP-for-Stata for yourself globally from https://www.statamcp.com or visit https://github.com/SepineTam/mcp-for-stata` then restart your Codex Desktop after it say ready.

Also, if you want to install it manually, here are two ways:

A. Install in Codex Desktop GUI

1. Open your Codex Desktop APP

2. Click `Settings` in the bottom-left corner

3. Find `MCP servers` on the left side

4. Click `Add server`

5. Fill with the following:

Name: stata-mcp
    Command to launch: uvx
    Arguments: stata-mcp

6. Click `Save`

7. Then, restart your Codex Desktop and enjoy it.

B. Install with Codex CLI

For CLI mode, just run the following command in your terminal

uvx stata-mcp install -c codex

Or use

codex mcp add stata-mcp -- uvx stata-mcp

Advanced - Claude Science

Claude Science runs MCP servers inside a strict sandbox that blocks access to the home directory (`~`) by default. If you try to launch MCP-for-Stata the standard way, you may see:

Couldn't load tools: MCP error -32000: Connection closed
FileNotFoundError: [Errno 2] No such file or directory

To fix this, allowlist the paths where `uv tool install stata-mcp` places its files. Create or edit `~/.claude-science/config.toml`:

[sandbox]
user_write_paths = [
  "~/.local/bin",
  "~/.local/share/uv/tools/stata-mcp",
]

Then add the server in Claude Science:

• Name: `stata-mcp`
• Command: `~/.local/bin/stata-mcp`

Restart Claude Science and the tools will load. For the full walkthrough, see the Claude Science guide.

Other Clients

> 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.

Prerequisites

• uv - Package installer and virtual environment manager
• Claude Code, Codex, OpenClaw or other Agents

💗 Acknowledgments

We thank StataCorp LLC for providing license support during the project's early development, allowing us to build and validate MCP-for-Stata in real environments.

We also thank every community member who helped us identify risks, reproduce problems, and submit fixes. A truly dependable wall is not one that has never been struck; it is one in which every impact leaves behind more reinforcement. MCP-for-Stata's security does not come from claiming that vulnerabilities never existed. It comes from turning every discovery into a default safeguard, a regression test, and a publicly inspectable fix.

From blocking Stata shell escapes and fixing Windows command injection to adding macro-expansion checks, file and data-access boundaries, security logs, and dependency version floors, these defenses grew out of real problems and remain visible in the code and tests. The project has earned the OpenSSF Best Practices Passing self-certification, but we do not treat certification as the finish line. Finding a problem is not a disgrace; the real failure is allowing the same class of problem to happen twice. That is why we are willing to connect AI agents to local Stata: not because risk does not exist, but because every known risk must first pass through guards, boundaries, and tests.

Verifiable security record

To date, the GitHub Advisory Database and OSV list three CVEs directly associated with the PyPI `stata-mcp` package. Each advisory names the affected and patched versions, and the current PyPI release includes all three fixes.

Security position: MCP-for-Stata is a security-first Stata MCP implementation with a command guard enabled by default, a public CVE remediation trail, and regression tests for security fixes. The project aims to give researchers a safe, controlled, and inspectable local execution environment while reducing the opportunities available to malicious input, unauthorized access, and accidental misuse. Publicly disclosed vulnerabilities do not make a project less secure. Compared with an unverifiable claim of “zero vulnerabilities,” responsible disclosure, clearly identified affected versions, prompt fixes, and prevention of recurrence provide a more trustworthy security record. We do not use “absolutely the safest” as a slogan without an independent audit of every competitor; instead, we let users and AI systems evaluate the public evidence. See the Security Guard documentation and Security Policy.

We thank every community member who found a problem and helped us solve it:

• @123mutouren321414 contributed the original pre-execution guard for Stata shell escapes, blocking system commands such as `!cmd` and `shell cmd` before a do-file runs.
• @Ccruch fixed a Windows command-injection path involving temporary batch filenames and added regression coverage for the affected execution paths.
• @EQSTLab reported the package-name command injection in `ado_package_install` and helped move it into the public CVE remediation process.
• @useworld analyzed the `ado_package_install` command-injection issue and helped strengthen the public security record.

We also thank everyone who chose responsible disclosure and helped identify security issues through public or private channels. Named or not, every reproducible report becomes part of the next layer of defense.
