Using Danube Tools

Access 100+ API tools for Gmail, GitHub, Notion, Google Calendar, and more through Danube's MCP integration.

Setup: If not configured yet, run bash scripts/setup.sh to add Danube MCP to OpenClaw.

When to Use

Use Danube when users want to:

• Send emails, create issues, manage calendars
• Interact with cloud services (GitHub, Notion, Google Drive)
• Execute any external API action

Don't use for: Local file operations, calculations, or non-API tasks.

Core Workflow

Every tool interaction follows this pattern:

1. Search for Tools

Use search_tools() with natural language:

search_tools("send email")        # → Gmail, Outlook
search_tools("create github issue") # → GitHub - Create Issue
search_tools("calendar events")   # → Google Calendar

2. Check Authentication

If tool requires credentials, guide user to connect:

"To use Gmail, you need to connect your account first.

Visit: https://danubeai.com/dashboard
1. Go to Tools section
2. Find Gmail and click 'Connect'
3. Follow the OAuth flow

Let me know when you're ready!"

Always check auth BEFORE attempting execution.

3. Gather Parameters

Ask for missing required parameters:

User: "Send an email"
You: "I can help! I need:
     - Who should I send it to?
     - What's the subject?
     - What should the message say?"

4. Execute Tool

execute_tool(
  tool_id="gmail-send-email-uuid",
  parameters={
    "to": "[e-mail]",
    "subject": "Meeting",
    "body": "Confirming our 2pm meeting."
  }
)

5. Handle Response

Success:

"✅ Email sent successfully to [e-mail]!"

Auth Error:

"🔐 Authentication failed. Reconnect Gmail at:
https://danubeai.com/dashboard → Tools → Gmail"

Other Error:

"⚠️ Failed: [error]. Let me help troubleshoot..."

Common Patterns

Email Tools

User: "Email [e-mail] about the project"

1. search_tools("send email") → Find Gmail
2. Check Gmail authentication
3. Extract: to="[e-mail]", subject="Project"
4. Ask: "What should the message say?"
5. Confirm: "I'll send email to [e-mail]. Proceed?"
6. execute_tool()
7. Report: "✅ Email sent!"

GitHub Tools

User: "Create issue about the login bug"

1. search_tools("github create issue")
2. Check GitHub authentication
3. Ask: "Which repository?"
4. Ask: "Describe the bug?"
5. execute_tool()
6. Report: "✅ Issue created: [link]"

Calendar Tools

User: "What's on my calendar today?"

1. search_tools("calendar events")
2. Check authentication
3. execute_tool(date=today)
4. Format results:
   "Here's your schedule:
   • 9:00 AM - Team standup
   • 2:00 PM - Client meeting"

Best Practices

✅ Do:

• Search first - Always use search_tools(), don't assume tool IDs
• Check auth - Verify credentials before execution
• Confirm actions - Get user approval for emails, issues, etc.
• Be specific - "Email sent to [e-mail]" not just "Done"
• Handle errors - Provide solutions, not just error messages

❌ Don't:

• Assume tool IDs without searching
• Auto-execute without confirmation
• Give vague responses like "Error" or "Done"
• Skip authentication checks

Available Tools

Tool	Purpose
list_services	Browse available services
search_tools	Find tools by query
get_service_tools	List tools for a service
execute_tool	Run tool with parameters
search_contacts	Find user's contacts

Error Handling

Authentication (401):

"🔐 [Service] requires authentication.
Visit https://danubeai.com/dashboard → Tools → [Service] → Connect"

Missing Parameters:

"I need:
• [param1]: [description]
• [param2]: [description]"

Rate Limit:

"⚠️ Hit rate limit for [Service].
• Try again in a few minutes
• Use alternative service
• Break into smaller batches"

Multi-Step Workflows

Some tasks need multiple tools:

User: "Email me a summary of today's GitHub commits"

1. search_tools("github commits") → Get tool
2. execute_tool() → Fetch commits
3. Format into summary
4. search_tools("send email") → Get Gmail
5. execute_tool() → Send email
6. Report: "✅ Sent summary of 5 commits!"

Communication Templates

Request Auth:

"To use [Service], connect your account:
1. Visit https://danubeai.com/dashboard
2. Tools → [Service] → Connect
3. Come back when ready!"

Confirm Execution:

"I'll [action] using [Tool].
Parameters: [list]
Proceed?"

Report Success:

"✅ Done!
[Specific result]
[Link if applicable]"
