What This Skill Does

Danube is a powerful integration layer designed to connect your OpenClaw AI agent to an expansive ecosystem of internet services. By abstracting away the complexities of authentication and tool-specific API integration, Danube provides a unified gateway to platforms like Gmail, Slack, GitHub, Notion, and Google Calendar. Instead of manually configuring dozens of individual SDKs, you simply authenticate your agent once with a single API key. Danube utilizes the Model Context Protocol (MCP) to bridge these external services, allowing your agent to discover, authenticate, and execute tasks across the web seamlessly.

Installation

To begin, ensure you have the OpenClaw environment ready. Install the skill using the command: clawhub install openclaw/skills/skills/preston-thiele/tools-marketplace. Once installed, perform the device authorization flow via your terminal: use a POST request to https://api.danubeai.com/v1/auth/device/code to receive your credentials. After visiting the verification URL provided, poll the /device/token endpoint to receive your api_key. Finally, add the configuration details provided in the documentation to your MCP settings file, ensuring the danube-api-key is correctly set. This establishes the persistent bridge needed for your agent to function autonomously.

Use Cases

Danube excels at automating workflows that bridge different SaaS platforms. Common use cases include syncing project management tasks by pulling GitHub issues into Notion, managing team communication by sending automated Slack updates based on calendar events, and executing complex data retrieval tasks using web search or scraping tools like Firecrawl. It is particularly effective for agents that need to cross-reference data from multiple sources, such as checking a Google Sheet for leads and then sending personalized emails via Gmail.

Example Prompts

1. "Danube, search for the GitHub issue tracker for our current project and create a new ticket for the bug I just reported in the logs."
2. "Check my Google Calendar for today's meetings, then send a Slack message to the #engineering channel informing the team that I will be 10 minutes late to the daily standup."
3. "Using Google Sheets, read the latest entries from the 'Monthly Sales' document and summarize the performance trends, then draft an email report to my manager."

Tips & Limitations

Always ensure you handle credentials securely. When a tool returns an auth_required error, use the store_credential command to inject the necessary API keys, which are then saved securely for future use. Keep in mind that while Danube supports a wide range of tools, some specific private API endpoints might require advanced configuration or specific scopes during the credential storage process. Always verify your agent's tool access permissions after adding a new service to maintain organizational security standards.
