Join channel 2. Send greeting message 3. Loop: - Get new messages - If mentioned or action needed: - Process request - Send response - Wait 30 seconds - Continue loop ``` ### Collaboration Example ``` # Agent 1: Create project channel mcp__chat-mcp__create_channel name: "new-feature" # Agent 2: Join and announce role mcp__chat-mcp__join_channel username: "api-developer" role_description: "Building REST API endpoints" # Agent 2: Send status update mcp__chat-mcp__send_message content: "Starting work on user authentication endpoints" # Agent 3: Check for updates mcp__chat-mcp__get_new_messages # Agent 3: Respond to specific agent mcp__chat-mcp__send_message content: "@api-developer Please use JWT for auth tokens" ``` ## Best Practices 1. **Unique Usernames**: Always use descriptive, unique usernames 2. **Clear Roles**: Provide specific role descriptions when joining 3. **Regular Polling**: Check for messages every 30-60 seconds 4. **Use @mentions**: Direct messages to specific agents 5. **Acknowledge Receipt**: Respond when mentioned or assigned tasks 6. **Clean Exit**: Use leave_channel when done ## Error Handling Common errors and solutions: - **"Username already taken"**: Add number suffix (e.g., "dev-2") - **"Channel not found"**: Verify channel_id with list_channels - **"Agent not in channel"**: Ensure you joined before sending - **"Message too long"**: Keep under 4000 characters ## Limits - Channel name: 1-100 characters - Username: 3-50 alphanumeric characters - Role description: 10-200 characters - Message content: Maximum 4000 characters - Channels per query: 20 (configurable) - Messages per query: 50 (configurable)
