Connect to Claude Desktop (Windows)

What you’ll need

Your Statista API Key
Claude Desktop installed on your PC
Node.js installed (we’ll help you install this)

Step-by-step instructions

Install Node.js

Open your web browser
Go to: https://nodejs.org/
Click the big green button that says “LTS” (Recommended for Most Users)
Find the downloaded file in your Downloads folder and double-click it
Click “Next” on everything until it finishes installing
Restart your computer

Get your Statista API Key

Keep this somewhere safe — you’ll need it in a moment!

Open Claude's configuration folder

Press Windows Key + R on your keyboard (this opens the “Run” box)
Type exactly: %APPDATA%\Claude
Press Enter — a folder will open

Create or edit the configuration file

Look for a file called claude_desktop_config.json.If the file EXISTS: Right-click it → Open with → NotepadIf the file DOESN’T exist:

Right-click in the empty space → New → Text Document
Name it: claude_desktop_config.json
Open it with Notepad

Add your configuration

Delete everything in the file (if there’s anything there), then paste this:

{
  "mcpServers": {
    "statista": {
      "command": "C:\\PROGRA~1\\nodejs\\npx.cmd",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.statista.ai/v1/mcp",
        "--transport",
        "http-only",
        "--header",
        "x-api-key: ${API_KEY}"
      ],
      "env": {
        "API_KEY": "INSERT KEY HERE"
      }
    }
  }
}

Add your API key

Find this line near the bottom:"API_KEY": "INSERT KEY HERE"Replace INSERT KEY HERE with your actual Statista API key from Step 2. For example, if your key is sk_1234abcd5678efgh, it should look like:

  "API_KEY": "sk_1234abcd5678efgh"

Important: Keep the quotes ("") around your key.

Save the file

In Notepad, click File → Save as .js
Close Notepad

Restart Claude Desktop

Completely close Claude Desktop (hard exit under “Files”)
Open Claude Desktop again

Test it!

Look for the Statista icon or tools indicator in Claude — this means it’s connected!

Make sure Statista is toggled on as a connector and then ask a Statista-related question. If the connection has been properly enabled, Claude will fetch live data from Statista for you!
