Overview

This guide will help you connect your AI assistant to Danube and execute your first tool. We’ll use Cursor as an example, but the same approach works for any MCP client.
The Danube MCP Server: https://mcp.danubeai.com/mcp

Step 1: Get Your API Key

1

Sign Up or Log In

Go to danubeai.com and create an account or sign in.
2

Navigate to API Keys

Click on API Keys.
3

Create a New Key

Click Create API Key, give it a name like “My MCP Client”, and copy the key.

Step 2: Choose Your Integration

Step 3: Make Your First Tool Call

MCP Prompt: “What services are available on Danube?”SDK: client.services.list(limit=5)
MCP Prompt: “Search for tools related to news”SDK: client.tools.search("news")
MCP Prompt: “Get the top 5 stories from Hacker News”SDK: client.tools.execute(tool_name="Hacker News - Get Top Stories With Content")

Troubleshooting

  • Make sure you completely restarted your MCP client
  • Check that your API key is correct
  • Verify the JSON/TOML syntax in your config file
  • Your API key may be invalid or expired
  • For MCP clients, ensure the header is named exactly danube-api-key (lowercase)
  • Generate a new API key from the dashboard
  • Check your internet connection
  • Verify the server is reachable: curl https://mcp.danubeai.com/mcp/health
