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

​
Step 1: Install NodeJS

  1. Open your web browser
  2. Go to: 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 2: Get Your Statista API Key

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

​
Step 3: 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 4: 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 5: 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" 
      } 
    } 
  } 
}

​
Step 6: 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

​
Step 7: Save the file

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

​
Step 8: Restart Claude Desktop

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

​
Step 9: 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, and then ask a Statista related question!
If it works, Claude will fetch live data from Statista for you!

​
Troubleshooting

If you get an error about Node.js
  • Make sure you installed Node.js from Step 1
  • Make sure you restarted your computer after installing Node.js
  • Try opening Claude again
If nothing happens
  • Make sure you completely closed and reopened Claude
  • Check that your API key is correct (no extra spaces)
  • Make sure the quotes are in the right places
If you see “invalid JSON”
  • Check that you have all the curly braces { and }
  • Check that every line except the last one in each section has a comma ,
  • Try copying the code again from this document
