The ultimate AI assistant integration for n8n workflow automation - Connect Claude Desktop, ChatGPT, and other AI assistants directly to your n8n instance for seamless workflow management, creation, and execution through the Model Context Protocol (MCP).

🚀 Installation & Usage

Method 2: Manual Installation

For development or customization:

```bash

Build the project

npm run build

🔧 MCP Client Setup

💡 Usage Examples

⚙️ Configuration

Environment Variables

Configure the following environment variables to connect to your n8n instance:

Setting Environment Variables

```bash

Getting Your n8n API Key

1. Open your n8n instance
2. Go to Settings → API Keys
3. Click Create API Key
4. Copy the generated key

How is this different from using n8n's web interface?

This MCP server enables AI-powered workflow management: - Natural language commands instead of clicking through UI - Automated workflow creation based on descriptions - Bulk operations across multiple workflows - Integration with AI assistant workflows and automation - Voice commands through AI assistants - Contextual help and suggestions from AI

Core Workflow Operations

Workflow Lifecycle Management

Creating Workflows

// Create a simple workflow
await callTool("create_workflow", {
  workflow: {
    name: "My Automation Workflow",
    nodes: [
      {
        id: "trigger",
        name: "Schedule Trigger",
        type: "n8n-nodes-base.scheduleTrigger",
        typeVersion: 1,
        position: [240, 300],
        parameters: {
          interval: [{ field: "unit", value: "hours" }]
        }
      },
      {
        id: "action",
        name: "HTTP Request",
        type: "n8n-nodes-base.httpRequest",
        typeVersion: 4,
        position: [460, 300],
        parameters: {
          url: "https://api.example.com/webhook",
          method: "POST"
        }
      }
    ],
    connections: {
      "Schedule Trigger": {
        "main": [[{ "node": "HTTP Request", "type": "main", "index": 0 }]]
      }
    }
  }
});

Workflow Management

// Activate a workflow
await callTool("activate_workflow", { id: "workflow-123" });

// Update a workflow
await callTool("update_workflow", {
  id: "workflow-123",
  workflow: { name: "Updated Workflow Name" }
});

// Deactivate a workflow
await callTool("deactivate_workflow", { id: "workflow-123" });

// Create and immediately activate
await callTool("create_workflow_and_activate", {
  workflow: { /* workflow configuration */ }
});

How do I connect AI assistants to n8n workflows?

This MCP server acts as a bridge between AI assistants (like Claude Desktop, Cline, or ChatGPT) and your n8n instance. Simply: 1. Install the MCP server: npx @makafeli/n8n-workflow-builder 2. Configure your AI assistant's MCP settings with your n8n credentials 3. Start using natural language to manage your n8n workflows

What can AI assistants do with my n8n workflows?

AI assistants can perform complete workflow management including: - List and browse existing workflows - Create new workflows with complex node configurations - Execute workflows manually or on-demand - Activate/deactivate workflows - Update and modify existing workflows - Monitor execution status and retrieve detailed logs - Manage workflow tags and organization - Generate security audits and compliance reports

Can I automate workflow creation with AI?

Yes! This is one of the key features. You can: - Describe workflows in natural language and have AI create them - Generate workflows from requirements or use cases - Modify existing workflows through conversational commands - Create workflow templates and variations automatically - Batch create similar workflows with different parameters

💼 Real Examples: Check out our Use Cases Guide for specific automation examples across different industries.

Cline (VS Code Extension)

Add this to your Cline MCP settings:

{
  "mcpServers": {
    "n8n-workflow-builder": {
      "command": "npx",
      "args": ["@makafeli/n8n-workflow-builder"],
      "env": {
        "N8N_HOST": "http://localhost:5678",
        "N8N_API_KEY": "your-api-key-here"
      }
    }
  }
}
