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:
- โ n8n-MCP Modern server
- โ 6 specialized Claude Code agents
- โ Required MCP dependencies (sequential-thinking, memory, filesystem, context7)

Manual Setup (if needed):
# Clone and setup
git clone https://github.com/eekfonky/n8n-mcp-modern.git
cd n8n-mcp-modern

npm run build
node scripts/setup-agents.js
Configuration:
Update your .mcp.json
with your n8n instance:
{
"mcpServers": {
"n8n-mcp-modern": {

๐๏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
