🌀 Zero-Cost n8n Setup with Docker & Community Proxy (MCP)

This guide walks through setting up a free, self-hosted instance of n8n with the n8n Community Proxy (MCP), entirely using Docker.

✅ Prerequisites

• 🐳 Docker & Docker Compose installed
• ✅ Free domain (optional, for HTTPS)
• ✅ Git + text editor (VSCode, etc.)
• ⛅ Optional: Cloudflare Tunnel for remote access

📁 Step 1: Create a Project Folder

mkdir n8n-zerocost && cd n8n-zerocost

🧾 Step 2: Create .env File

# .env

N8N_BASIC_AUTH_USER=admin
N8N_BASIC_AUTH_PASSWORD=strongpassword

N8N_HOST=localhost
N8N_PORT=5678

N8N_EDITOR_BASE_URL=https://n8n.community
N8N_PROTOCOL=http
WEBHOOK_TUNNEL_URL=https://n8n.community

N8N_PERSONALIZATION_ENABLED=false
N8N_DIAGNOSTICS_ENABLED=false

⚙️ Step 3: Create docker-compose.yml

# docker-compose.yml

version: "3.7"
services:
  n8n:
    image: n8nio/n8n:latest
    restart: always
    ports:
      - "5678:5678"
    env_file:
      - .env
    volumes:
      - ./n8n_data:/home/node/.n8n
    environment:
      - N8N_COMMUNITY_PACKAGES_ALLOWED=true
      - N8N_TUNNEL_SUBDOMAIN=your-subdomain  # Optional

🌍 Step 4: Launch n8n

docker compose up -d

Check logs:

docker logs -f n8n

🔐 Step 5: Access Your n8n Editor

• Locally: http://localhost:5678
• Remotely (if using a tunnel): via n8n.community (MCP handles public tunnel)

☁️ Optional: Use Cloudflare Tunnel (Zero Trust)

cloudflared tunnel --url http://localhost:5678

🧪 Step 6: First Workflow

1. Go to your n8n instance.
2. Create a simple trigger like HTTP Request ➝ Respond with Message.
3. Test it with the tunnel or MCP URL.

📦 Step 7: (Optional) Install Community Nodes

You can now install any free community package under Settings ➝ Community Nodes.

📁 Volumes

Your workflows and data will be stored in:

./n8n_data/

✅ Tips for Zero Cost Hosting

🚨 Security

• Always use strong username/password in .env
• For production, use HTTPS (Cloudflare tunnel or NGINX)

✅ Done!

Your zero-cost n8n is now live and running with Docker and MCP!
