How It Works

Claude Desktop connects directly to Danube’s remote MCP server using OAuth 2.0:
  1. Claude Desktop discovers Danube’s OAuth configuration automatically
  2. You authorize once with your API key on Danube’s auth page
  3. Claude Desktop receives a token and connects via HTTP/SSE
  4. Danube tools become available in your conversations

​
Troubleshooting

  • Ensure you’re on a Claude Pro, Max, Team, or Enterprise plan (custom connectors require a paid plan)
  • Verify the URL is exactly https://mcp.danubeai.com/mcp
  • Try removing and re-adding the connector
  • Check your internet connection
  • Verify the server is reachable: visit https://mcp.danubeai.com/mcp/health in your browser
  • Try again after a few moments
  • Verify your Danube API key is correct
  • Try generating a new API key from the dashboard
  • Ensure your Danube account is active
  • Click the + button in the chat input and ensure Danube is toggled on under Connectors
  • Try starting a new conversation
  • Completely quit and relaunch Claude Desktop
