# Connect to Claude Desktop (Windows)

> Connect the Statista MCP Server to Claude Desktop on 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

<Steps>
  <Step title="Install Node.js" icon="node-js">
    1. Open your web browser
    2. Go to: [https://nodejs.org/](https://nodejs.org/)
    3. Click the big green button that says "LTS" (Recommended for Most Users)
    4. Find the downloaded file in your Downloads folder and double-click it
    5. Click "Next" on everything until it finishes installing
    6. Restart your computer
  </Step>

  <Step title="Get your Statista API Key" icon="key">
    Keep this somewhere safe — you'll need it in a moment!
  </Step>

  <Step title="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
  </Step>

  <Step title="Create or edit the configuration file">
    Look for a file called `claude_desktop_config.json`.

    **If the file EXISTS:**
    Right-click it → Open with → Notepad

    **If the file DOESN'T exist:**

    * Right-click in the empty space → New → Text Document
    * Name it: `claude_desktop_config.json`
    * Open it with Notepad
  </Step>

  <Step title="Add your configuration">
    **Delete everything** in the file (if there's anything there), then paste this:

    ```json theme={null}
    {
      "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"
          }
        }
      }
    }
    ```
  </Step>

  <Step title="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:

    ```json theme={null}
      "API_KEY": "sk_1234abcd5678efgh"
    ```

    <Info>
      Important: Keep the quotes ("") around your key.
    </Info>
  </Step>

  <Step title="Save the file">
    * In Notepad, click File → Save as .js
    * Close Notepad
  </Step>

  <Step title="Restart Claude Desktop">
    * Completely close Claude Desktop (hard exit under "Files")
    * Open Claude Desktop again
  </Step>

  <Step title="Test it!">
    Look for the Statista icon or tools indicator in Claude — this means it's connected!

    <Info>
      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!
