Claude MCP Data Explorer for Windows

A TypeScript implementation of a Model Context Protocol (MCP) server for data exploration with Claude. This server integrates with Claude Desktop and enables advanced data analysis by providing tools to load CSV files and execute JavaScript data analysis scripts.

Prerequisites

Installation (Updated for Windows)

  1. Clone this repository

    git clone https://github.com/tofunori/claude-mcp-data-explorer.git

cd claude-mcp-data-explorer

  1. Install dependencies

    npm install

  2. Build and run setup script

    npm run setup

This will:

* Build the TypeScript code to JavaScript
* Configure Claude Desktop to use the compiled JavaScript
* Create necessary directories
  1. Restart Claude Desktop and enable Developer Mode
* Close Claude Desktop completely
* Start Claude Desktop
* Go to Help → Enable Developer Mode

Manual Testing

You can test the server directly by running:

npm run build
npm run start

The server should start without errors. If you can run this successfully, Claude Desktop should be able to use the server as well.

How It Works

This MCP server provides two main tools for Claude:

  1. load-csv - Loads CSV data into memory for analysis
  2. run-script - Executes JavaScript code for data processing and analysis

It also includes a prompt template that guides Claude through a structured data exploration process.

Usage

  1. Start Claude Desktop

  2. Select the "Explore Data" prompt template

* This prompt will appear in Claude Desktop after setup
  1. Enter CSV file path and exploration topic
* Example file path: `C:/Users/YourName/Documents/data.csv`
* Example topic: "Sales trends by region"
  1. Let Claude analyze your data
* Claude will load the CSV file and generate insights automatically
* The server handles large files efficiently using chunking

Troubleshooting

  1. Claude doesn't show the MCP server
* Check the configuration file at `%APPDATA%\Claude\claude_desktop_config.json`
* It should point to the compiled JavaScript file in the dist directory
* Try rebuilding the project with `npm run build`
* Enable Developer Mode and check the MCP Log File (Developer → Open MCP Log File)
* Use Developer → Reload All MCP Servers to force refresh
  1. Permission errors reading files
* Make sure Claude has access to the CSV file location
* Try using absolute paths with forward slashes (`/`) or escaped backslashes (`\\`)
  1. JavaScript errors in scripts
* Check that your script is compatible with the allowed modules
* Review any error messages in Claude's response
