N8N with Claude Code

Introduction to n8n and AI Terminal Integration

• The video highlights a significant change in how n8n is used by integrating it with AI terminal tools like Claude Code.
• This combination allows n8n to execute Claude agents, workflows, and skills, greatly enhancing its automation capabilities.

Requirements for the Setup

• n8n Instance: An active n8n instance is required. The creator strongly recommends self-hosting on a Hostinger VPS due to current sales and a quick 5-minute setup process.
• AI Terminal Tool: Options include:
  • Claude Code: Recommended by the creator. Requires a Pro subscription.
  • Gemini CLI: Free with certain usage limits.
  • Codex: Mentioned as a potential but "janky" alternative.
• Installation Location: AI terminal tools can be installed on any Linux-based machine, including macOS, Windows (via WSL), Raspberry Pi, or a Hostinger VPS. The creator prefers an Ubuntu server in his local server room for "easy access."

The Core Connection: SSH Node

• The primary method for n8n to interact with the AI terminal tool is through its SSH node.
• This node allows n8n to log into a remote server and execute shell commands.
• Setting up SSH: Users need to create SSH credentials within n8n, providing the host IP address, port (default 22), username, and password/private key.

Demonstrations of Functionality

1. Basic Execution

• A simple hostname command is executed via SSH to verify server connectivity.
• The claude --version command is used to confirm Claude Code is installed and accessible.

2. Basic Execution with Headless Mode

• The command claude -p "Why do pugs look so weird?" demonstrates Claude Code in "headless mode" (-p for print).
• Claude provides a detailed textual response, showcasing its ability to answer queries without direct terminal interaction.

3. Leveraging Context and Local Files

• The creator changes directory (cd) to a local project folder before running a Claude command.
• Claude is asked: "Hey, is this video going to be any good?" The AI analyzes local files (scripts, notes) related to the video and provides a contextual review.
• Key Insight: Giving n8n access to Claude Code effectively grants n8n access to a "super powerful context-filled agent" capable of understanding local files and project context.

4. Advanced Skills and Multi-Agent Deployment

• A custom "Unifi skill" (a Python script) is used to interact with a Unifi network environment.
• Claude is prompted: "Use your Unifi skill to do 3 things: First, rate the wifi. Second, rate the overall network performance. Third, rate security config. Deploy three agents, one for each task."
• The demonstration uses a custom Claude Code Monitor dashboard (built with Twingate) to visualize Claude deploying and managing three agents simultaneously.
• These agents execute Python scripts, perform network checks, and provide a comprehensive analysis of the Unifi setup, even identifying memory usage issues on network devices.
• Architectural Shift: n8n acts as the orchestrator, simplifying complex tasks. The detailed logic and execution of AI agents and skills reside within Claude Code, which can be seen as the "actual IT department."

5. Conversational Sessions

• The video introduces the concept of maintaining conversational sessions with AI agents using --session-id <UUID> and -r (resume) flags in Claude commands.
• A JavaScript node in n8n is used to generate a unique session ID (UUID).
• Subsequent SSH commands utilize this session ID and the -r flag to maintain context across multiple interactions, allowing for a flowing conversation with the AI.

6. External Interfaces (Slack Integration)

• An n8n workflow is built to integrate Slack with Claude Code, enabling mobile interaction.
• Users can tag the n8n bot in Slack and ask questions, receiving responses from Claude Code via n8n.
• The workflow manages the session ID and a "done?" true/false dropdown in Slack to continue or end the conversation.
• Demonstrations:
  • Comparing "nano vs. neovim" text editors.
  • Generating YouTube video ideas related to hacking and n8n.
  • Checking the health of a NAS (Network-Attached Storage) server and diagnosing Ceph storage issues. Claude identifies critical issues and suggests actions.

Conclusion: Overpowered Automation

• The combination of n8n and AI terminal tools like Claude Code creates an "overpowered" automation system.
• n8n acts as the orchestrator, managing workflows and external interfaces, while Claude Code provides the advanced AI capabilities, context management, and multi-agent deployment.
• This approach allows for local control over files and processes, appealing to those who prefer on-premises solutions.
• The creator encourages viewers to experiment with this setup and share their ideas.
