Quick Data for Windows MCP

Windows-optimized fork of disler/quick-data-mcp for Claude Desktop

Universal data analytics capabilities for JSON/CSV files - now working seamlessly on Windows!

Python 3.9+ Windows Claude Desktop Original Project

🚀 What This Does

This is a Windows-optimized fork of the excellent quick-data-mcp project by @disler.

The original project provides powerful MCP server capabilities for data analytics, and this fork specifically addresses Windows compatibility issues and Claude Desktop integration challenges.

**This is my first ever try at this. Please feel free to give suggestions and or criticisms. I loved the quick data mcp for claude code. There was nothing available like it for claude desktop so with the help of claude code we now have it.

Key Improvements Over Original:

  • ✅ Windows Path Handling - Proper Windows file path support
  • ✅ Claude Desktop Ready - Pre-configured batch launchers and setup
  • ✅ Dependency Management - Automated installation scripts
  • ✅ Troubleshooting - Complete guides for common Windows issues

✨ Key Features

  • Universal Data Support - Works with any CSV/JSON file structure
  • Windows Path Optimization - Handles Windows file paths correctly
  • Claude Desktop Integration - Pre-configured for seamless setup
  • Automatic Schema Discovery - Analyzes your data and suggests analyses
  • 32+ Analytics Tools - From basic stats to advanced ML features
  • Interactive Visualizations - Create charts with Plotly
  • Memory Management - Optimized for large datasets

🏁 Quick Start for Windows

Prerequisites

Installation

  1. Download or clone this repository:

    git clone https://github.com/Beaulewis1977/quick-data-for-windows-mcp.git
cd quick-data-for-windows-mcp

  2. Install dependencies:

    install_dependencies.bat

  3. Test the server:

    test_server.bat

  4. Configure Claude Desktop:

    Copy the fixed configuration to Claude Desktop:

🛠️ Configuration

Manual Configuration

If the automatic setup doesn't work, manually edit your Claude Desktop config:

Location: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "quick-data-windows": {
      "command": "python",
      "args": [
        "C:\\path\\to\\your\\quick-data-for-windows-mcp\\main.py"
      ],
      "cwd": "C:\\path\\to\\your\\quick-data-for-windows-mcp",
      "env": {
        "LOG_LEVEL": "INFO",
        "PYTHONPATH": "C:\\path\\to\\your\\quick-data-for-windows-mcp\\src"
      }
    }
  }
}

Alternative: Using UV Package Manager

If you prefer UV (recommended for Python dependency management):

{
  "mcpServers": {
    "quick-data-windows": {
      "command": "uv",
      "args": [
        "--directory",
        "C:\\path\\to\\your\\quick-data-for-windows-mcp",
        "run",
        "python",
        "main.py"
      ]
    }
  }
}

🧪 Testing the Server

Test the server standalone (before Claude Desktop integration):

python main.py

Expected output:

Quick Data for Windows MCP v1.0.0
Server running on stdio...

📊 Example Workflows

Sales Data Analysis

1. Load sales_data.csv as "sales"
2. Show correlations in sales dataset
3. Create bar chart of sales by product_category 
4. Detect outliers in revenue column
5. Generate dashboard with top products and regional trends

Data Quality Assessment

1. Load customer_data.csv as "customers"
2. Validate data quality for customers dataset
3. Analyze distributions for age column
4. Segment by customer_type column

🔍 Troubleshooting

Common Issues

"Module not found" errors:

  • Ensure Python is in your PATH
  • Run pip install -r requirements.txt manually
  • Check that PYTHONPATH is set correctly in config

"File not found" errors:

  • Use full Windows paths: C:\Users\...
  • Avoid relative paths like .\data\file.csv
  • Check file permissions

Claude Desktop not finding server:

  • Restart Claude Desktop after config changes
  • Check config file syntax with JSON validator
  • Verify file paths are correct (no typos)

Getting Help

  1. Check that Python 3.9+ is installed: python --version
  2. Verify dependencies: pip list | findstr pandas
  3. Test server manually: python main.py
  4. Check Claude Desktop logs for errors
