What This Skill Does

Danube is an essential connectivity layer for your OpenClaw AI agent, acting as a gateway to the modern web services ecosystem. By leveraging the Model Context Protocol (MCP), Danube enables your agent to search, authenticate, and execute tools across a vast array of popular platforms—including Gmail, Slack, GitHub, Notion, and Google Calendar—all managed through a unified API key architecture. Instead of hard-coding every individual integration, Danube provides a standardized bridge for your agent to interact with external APIs, significantly expanding its functional capabilities.

Installation

To install this skill, run the following command in your terminal: clawhub install openclaw/skills/skills/preston-thiele/danube-tools

After installation, follow the two-stage setup process. First, initialize your device authorization flow by executing the provided cURL command to the Danube API to receive your credentials. Once you have your API key, update your OpenClaw MCP configuration by adding the 'danube' server block with your unique API key in the headers. This ensures your agent is authorized to communicate securely with the Danube platform.

Use Cases

Danube excels in scenarios requiring cross-platform orchestration. You can use it to automate email correspondence via Gmail or SendGrid, streamline project management by creating GitHub issues or updating Notion databases, and manage personal productivity through Google Calendar scheduling. Furthermore, it allows for sophisticated data gathering by enabling web searches through services like Exa or Serper and content scraping via Firecrawl. Whether you are managing complex development workflows or simple personal reminders, Danube provides the tools to get the job done efficiently.

Example Prompts

1. "Search for the latest GitHub issue created by the team today and draft a summary in a new Notion page."
2. "Find any free slots in my Google Calendar for next Tuesday and send a meeting invite to the project lead via Gmail."
3. "Use Firecrawl to extract the main content from the provided documentation URL and summarize the key technical requirements."

Tips & Limitations

Always check if a specific tool requires dedicated credentials. If you receive an auth_required error from execute_tool, use the store_credential function to securely input your specific service keys. Keep in mind that external API limits are dictated by the service providers themselves. Ensure your agent is operating within the rate limits of the services you interact with to avoid temporary service interruptions.
