n8n Workflow: AI-Powered Cloudflare DNS Management Chat Assistant

This n8n workflow provides an intelligent chat assistant that allows users to manage Cloudflare DNS records through natural language commands. By integrating an AI agent with a custom n8n workflow tool, it simplifies complex DNS operations, making them accessible via a conversational interface.

What it does

This workflow acts as a central hub for an AI chat assistant, enabling it to understand and execute Cloudflare DNS management tasks. Here's a step-by-step breakdown:

1. Listens for Chat Messages: The workflow is triggered whenever a new chat message is received, initiating a conversation with the AI assistant.
2. Manages Chat History: It utilizes a Postgres Chat Memory to store and retrieve conversation history, allowing the AI to maintain context throughout the interaction.
3. Processes with AI Agent: The received chat message and conversation history are fed into an AI Agent (powered by OpenAI Chat Model). This agent is configured with a custom tool to interact with n8n workflows.
4. Executes Cloudflare DNS Operations (via Tool): The AI Agent, based on the user's request, decides whether to call the "Call n8n Workflow Tool". This tool is designed to trigger another n8n workflow (presumably the one handling the actual Cloudflare API calls).
5. Handles Workflow Tool Output: The output from the "Call n8n Workflow Tool" is processed.
6. Splits and Processes Results: The workflow uses a "Split Out" node to handle multiple results from the tool, if any, ensuring each item is processed individually.
7. Responds to User: Although not explicitly shown in the provided JSON (which is a sub-workflow, likely called by the tool), the ultimate goal is for the AI agent to formulate a response back to the user based on the success or failure of the DNS operation.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance.
• OpenAI API Key: For the OpenAI Chat Model used by the AI Agent.
• PostgreSQL Database: For the Postgres Chat Memory to store conversation history.
• Cloudflare Account and API Token: The actual Cloudflare DNS management workflow (which this workflow calls as a tool) will require Cloudflare API credentials.
• Another n8n Workflow for Cloudflare API Calls: This workflow acts as the AI interface. You will need a separate n8n workflow that contains the actual HTTP Request nodes to interact with the Cloudflare API for managing DNS records (e.g., listing, creating, updating, deleting records). This separate workflow will be configured as the "Call n8n Workflow Tool."

Setup/Usage

1. Import the Workflow: Import the provided JSON into your n8n instance.
2. Configure Credentials:
   • OpenAI Chat Model: Configure your OpenAI API credentials.
   • Postgres Chat Memory: Set up your PostgreSQL database credentials for chat memory.
3. Configure the "Call n8n Workflow Tool":
   • You will need to create a separate n8n workflow that performs the actual Cloudflare DNS operations (e.g., using HTTP Request nodes to interact with the Cloudflare API).
   • In the "Call n8n Workflow Tool" node (node ID 1205), configure it to call your Cloudflare DNS management workflow. Ensure the Cloudflare workflow is set up with an "Execute Workflow Trigger" (node ID 837 in the example, which is likely a placeholder for the target workflow's trigger) to receive commands from this AI agent workflow.
4. Activate the Workflow: Once configured, activate the workflow.
5. Interact via Chat: The "When chat message received" trigger will listen for incoming messages. You can then interact with the AI assistant through the n8n chat interface or any integrated chat platform.

This workflow provides a powerful foundation for building conversational interfaces for managing external services like Cloudflare, leveraging the capabilities of AI agents and n8n's workflow automation.
