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.

Test it!

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