Troubleshooting

​
”Connection refused” or timeout

  • Check your internet connection
  • Verify the URL is exactly https://api.bananasplit.net/mcp
  • Restart your AI client

​
Browser doesn’t open for auth

  • Some clients need manual URL opening — check the client’s output for a login URL
  • Ensure your default browser is set correctly

​
”Unauthorized” after approving

  • The consent may have expired — try reconnecting
  • Check if you denied permissions accidentally
