What is Danube?
Danube is a comprehensive integration layer designed to give AI agents autonomous access to the modern web. By consolidating over 100 services and 21 specialized tools into a single API and MCP server, it removes the friction of managing disparate authentications and complex API documentation. This is a vital resource for developers using Openclaw Skills who want to build agents capable of interacting with real-world applications like Notion, GitHub, Stripe, and Google Workspace without writing custom connectors for every platform.
The skill provides a standardized way for agents to discover tools via semantic search, manage user credentials securely, and even handle financial transactions through an integrated agent wallet. Whether you are building a simple automation bot or a complex autonomous agent, Danube provides the plumbing necessary for high-level digital agency.
Danube Use Cases
- Send automated emails and messages through Gmail, Slack, or Resend based on agent triggers.
- Manage software development projects by creating GitHub issues, pull requests, and tracking Linear tickets.
- Automate data entry and retrieval from Google Sheets and Notion databases for research or reporting.
- Generate and process media assets using AI models from Replicate, Stability AI, and AssemblyAI.
- Execute complex infrastructure commands across AWS, DigitalOcean, and Supabase directly from an agent conversation.
How Danube Works
- The agent initiates a device authorization flow to obtain a unique API key for the user.
- The Danube MCP server is integrated into the agent's environment, exposing a standardized set of tools.
- The agent performs a semantic search to find the specific tool or service needed for a user's request.
- For services requiring authentication, the agent prompts the user or stores provided credentials via the secure storage tool.
- The agent executes single, batch, or workflow-based tool calls to perform actions across external APIs.
- Real-time feedback and execution results are returned to the agent to inform the next step of the conversation.
Danube Setup
To get started with this skill in your Openclaw Skills environment, follow these steps:
- Initiate the device authorization flow:
curl -s -X POST https://api.danubeai.com/v1/auth/device/code -H "Content-Type: application/json" -d '{"client_name": "My Agent"}'
- Have the user authorize the agent at the provided URL.
- Poll for your persistent API key:
curl -s -X POST https://api.danubeai.com/v1/auth/device/token -H "Content-Type: application/json" -d '{"device_code": "YOUR_DEVICE_CODE"}'
- Add the Danube server to your MCP configuration:
{
"mcpServers": {
"danube": {
"url": "https://mcp.danubeai.com/mcp",
"headers": {
"danube-api-key": "YOUR_API_KEY"
}
}
}
}
