    • Log in to your account (or sign up if you don’t have one)
    • Copy your API key from the dashboard
  3. Edit the config file to add the TabPFN server:
{
    "mcpServers": {
      "tabpfn": {
        "url": "https://api.priorlabs.ai/mcp/server",
        "headers": {
          "Authorization": "Bearer YOUR_API_KEY_HERE"
        }
      }
    }
  }
  1. Replace YOUR_API_KEY_HERE with your actual API key from step 2
  2. Save the config file and restart Claude Desktop for the changes to take effect
