๐Ÿš€ Quick Start

Simple Installation

# Install globally from npmjs.org
npm install -g @eekfonky/n8n-mcp-modern

# Start using immediately
n8n-mcp

Claude Code Integration

One-Command Setup:

# Install globally with auto-setup
npm install -g @eekfonky/n8n-mcp-modern

# Or via Claude Code (recommended)
claude mcp add @eekfonky/n8n-mcp-modern

This automatically installs:

  • โœ… n8n-MCP Modern server
  • โœ… 6 specialized Claude Code agents
  • โœ… Required MCP dependencies (sequential-thinking, memory, filesystem, context7)
  • โœ… Dynamic node discovery system
  • โœ… Enhanced database schema

Manual Setup (if needed):

# Clone and setup
git clone https://github.com/eekfonky/n8n-mcp-modern.git
cd n8n-mcp-modern
npm install
npm run build
node scripts/setup-agents.js

Configuration: Update your .mcp.json with your n8n instance:

{
  "mcpServers": {
    "n8n-mcp-modern": {
      "command": "npx",
      "args": ["-y", "@eekfonky/n8n-mcp-modern"],
      "env": {
        "N8N_API_URL": "https://your-n8n-instance.com",
        "N8N_API_KEY": "your-api-key"
      }
    }
  }
}

That's it! Start building workflows with AI agents:

"Create a workflow that sends a Slack message when a new GitHub issue is opened"

๐Ÿ—๏ธ Hybrid Architecture

Claude Code Sub-Agents (6 Specialists)

Master Orchestrator:

  • n8n-control (Opus) - Strategic planning & agent coordination

Core Specialists:

  • n8n-architect (Opus) - Workflow architecture & design patterns
  • n8n-node (Sonnet) - Node selection & configuration expert
  • n8n-connector (Sonnet) - Authentication & API connectivity
  • n8n-scriptguard (Sonnet) - JavaScript validation & security
  • n8n-guide (Haiku) - Documentation & user guidance

Dynamic Node Discovery

Real-Time Intelligence:

  • Connects to your n8n instance via REST API
  • Discovers 675+ nodes (built-in + community) automatically
  • Stores schemas and capabilities in SQLite database
  • Updates when you install new community nodes

Agent Delegation Examples:

# Complex workflows
"n8n-control, create a data processing pipeline with error handling"

# Node expertise
"n8n-node, find the best way to connect to PostgreSQL"

# Authentication help
"n8n-connector, set up OAuth for Google Sheets integration"

# Code validation
"n8n-scriptguard, review this JavaScript for security issues"

# Documentation
"n8n-guide, explain how webhook triggers work"

Intelligent Learning System

Pattern Recognition:

  • Learns from successful workflow patterns
  • Stores node configurations that work well together
  • Suggests optimizations based on usage history
  • Builds knowledge graph of effective connections

Zero Static Dependencies:

  • No hardcoded node lists or schemas
  • Everything discovered dynamically from your instance
  • Adapts automatically to your specific n8n setup

๐Ÿ”„ Maintenance & Updates

Smart Updater

# Check for updates and optionally apply them
npm run update

# Options:
npm run update --force          # Force update regardless of version
