stats-compass-mcp

MCP server that exposes stats-compass-core tools to LLMs like ChatGPT, Claude, and Gemini.

What is this?

This package turns the stats-compass-core toolkit into an MCP (Model Context Protocol) server. Once running, any MCP-compatible client (ChatGPT, Claude, Cursor, VS Code, etc.) can use your data analysis tools directly.

Installation

pip install stats-compass-mcp

Quick Start

Start the server

stats-compass-mcp serve

Configure your MCP client

For Claude Desktop (Recommended)

The easiest way to run this server is using uvx (part of the uv toolkit), which downloads and runs the server in an isolated environment without installation.

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "stats-compass": {
      "command": "uvx",
      "args": ["stats-compass-mcp", "serve"]
    }
  }
}

Manual Installation

If you prefer to install it globally:

pip install stats-compass-mcp

Then configure your client:

{
  "mcpServers": {
    "stats-compass": {
      "command": "stats-compass-mcp",
      "args": ["serve"]
    }
  }
}
