HTTP Deployment Guide for n8n-MCP

Deploy n8n-MCP as a remote HTTP server to provide n8n knowledge to compatible MCP Client from anywhere.

🎯 Overview

n8n-MCP HTTP mode enables:

• ☁️ Cloud deployment (VPS, Docker, Kubernetes)
• 🌐 Remote access from any Claude Desktop /Windsurf / other MCP Client
• 🔒 Token-based authentication
• ⚡ Production-ready performance (~12ms response time)
• 🚀 Optional n8n management tools (16 additional tools when configured)
• ❌ Does not work with n8n MCP Tool

📐 Deployment Scenarios

1. Local Development (Simplest)

Use stdio mode - Claude Desktop connects directly to the Node.js process:

Claude Desktop → n8n-mcp (stdio mode)

• ✅ No HTTP server needed
• ✅ No authentication required
• ✅ Fastest performance
• ❌ Only works locally

2. Local HTTP Server

Run HTTP server locally for testing remote features:

Claude Desktop → http-bridge.js → localhost:3000

• ✅ Test HTTP features locally
• ✅ Multiple Claude instances can connect
• ✅ Good for development
• ❌ Still only local access

3. Remote Server

Deploy to cloud for access from anywhere:

Claude Desktop → mcp-remote → https://your-server.com

• ✅ Access from anywhere
• ✅ Team collaboration
• ✅ Production-ready
• ❌ Requires server setup
• Deploy to your VPS - if you just want remote acces, consider deploying to Railway -> Railway Deployment Guide

📋 Prerequisites

Server Requirements:

• Node.js 16+ or Docker
• 512MB RAM minimum
• Public IP or domain name
• (Recommended) SSL certificate for HTTPS

Client Requirements:

• Claude Desktop
• Node.js 18+ (for mcp-remote)
• Or Claude Pro/Team (for native remote MCP)

🚀 Quick Start

Option 1: Docker Deployment (Recommended for Production)

# 1. Create environment file
cat > .env << EOF
AUTH_TOKEN=$(openssl rand -base64 32)
MCP_MODE=http
PORT=3000
# Optional: Enable n8n management tools
# N8N_API_URL=https://your-n8n-instance.com
# N8N_API_KEY=your-api-key-here
# Security Configuration (v2.16.3+)
# Rate limiting (default: 20 attempts per 15 minutes)
AUTH_RATE_LIMIT_WINDOW=900000
AUTH_RATE_LIMIT_MAX=20
# SSRF protection mode (default: strict)
# Use 'moderate' for local n8n, 'strict' for production
WEBHOOK_SECURITY_MODE=strict
EOF

# 2. Deploy with Docker
docker run -d \
  --name n8n-mcp \
  --restart unless-stopped \
  --env-file .env \
  -p 3000:3000 \
  ghcr.io/czlonkowski/n8n-mcp:latest

# 3. Verify deployment
curl http://localhost:3000/health

Option 2: Local Development (Without Docker)

# 1. Clone and setup
git clone https://github.com/czlonkowski/n8n-mcp.git
cd n8n-mcp
npm install
npm run build
npm run rebuild

# 2. Configure environment
export MCP_MODE=http
export AUTH_TOKEN=$(openssl rand -base64 32)
export PORT=3000

# 3. Start server
npm run start:http

Option 3: Direct stdio Mode (Simplest for Local)

Skip HTTP entirely and use stdio mode directly:

{
  "mcpServers": {
    "n8n-local": {
      "command": "node",
      "args": [
        "/path/to/n8n-mcp/dist/mcp/index.js"
      ],
      "env": {
        "N8N_API_URL": "https://your-n8n-instance.com",
        "N8N_API_KEY": "your-api-key-here"
      }
    }
  }
}

💡 Save your AUTH_TOKEN - clients will need it to connect!

⚠️ Security Note: Store API keys securely and never commit them to version control.

🏗️ Architecture

How HTTP Mode Works

┌─────────────────┐        ┌─────────────┐        ┌──────────────┐
│ Claude Desktop  │ stdio  │ mcp-remote  │  HTTP  │  n8n-MCP     │
│ (stdio only)    ├───────►│ (bridge)    ├───────►│  HTTP Server │
└─────────────────┘        └─────────────┘        └──────────────┘
                                                           │
                                                           ▼
                                                   ┌──────────────┐
                                                   │ Your n8n     │
                                                   │ Instance     │
                                                   └──────────────┘

Key Points:

• Claude Desktop only supports stdio communication
• mcp-remote acts as a bridge, converting stdio ↔ HTTP
• n8n-MCP server connects to one n8n instance (configured server-side)
• All clients share the same n8n instance (single-tenant design)

🌐 Reverse Proxy Configuration

URL Configuration (v2.7.14+)

n8n-MCP intelligently detects your public URL:

Priority Order:

1. Explicit Configuration (highest priority):

   BASE_URL=https://n8n-mcp.example.com  # Full public URL
   # or
   PUBLIC_URL=https://api.company.com:8443/mcp
   

2. Auto-Detection (when TRUST_PROXY is enabled):

   TRUST_PROXY=1  # Required for proxy header detection
   # Server reads X-Forwarded-Proto and X-Forwarded-Host
   

3. Fallback (local binding):

   # No configuration needed
   # Shows: http://localhost:3000 (or configured HOST:PORT)
   

What You'll See in Logs:

[INFO] Starting n8n-MCP HTTP Server v2.7.17...
[INFO] Server running at https://n8n-mcp.example.com
[INFO] Endpoints:
[INFO]   Health: https://n8n-mcp.example.com/health
[INFO]   MCP:    https://n8n-mcp.example.com/mcp

Trust Proxy for Correct IP Logging

When running n8n-MCP behind a reverse proxy (Nginx, Traefik, etc.), enable trust proxy to log real client IPs instead of proxy IPs:

# Enable trust proxy in your environment
TRUST_PROXY=1  # Trust 1 proxy hop (standard setup)
# or
TRUST_PROXY=2  # Trust 2 proxy hops (CDN → Load Balancer → n8n-mcp)

Without TRUST_PROXY:

[INFO] GET /health { ip: '172.19.0.2' }  # Docker internal IP

With TRUST_PROXY=1:

[INFO] GET /health { ip: '203.0.113.1' }  # Real client IP

This is especially important when:

• Running in Docker/Kubernetes
• Using load balancers
• Debugging client issues
• Implementing rate limiting

🔐 Security Setup

Authentication

All requests require Bearer token authentication:

# Test authentication
curl -H "Authorization: Bearer $AUTH_TOKEN" \
     https://your-server.com/health

SSL/HTTPS (Strongly Recommended)

Use a reverse proxy for SSL termination:

Nginx example:

server {
    listen 443 ssl;
    server_name your-domain.com;
    
    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;
    
    location /mcp {
        proxy_pass http://localhost:3000;
        proxy_set_header Authorization $http_authorization;
        # Important: Forward client IP headers
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

Caddy example (automatic HTTPS):

your-domain.com {
    reverse_proxy /mcp localhost:3000
}

💻 Client Configuration

⚠️ Requirements: Node.js 18+ must be installed on the client machine for mcp-remote

Method 1: Using mcp-remote (Recommended)

{
  "mcpServers": {
    "n8n-remote": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://your-server.com/mcp",
        "--header",
        "Authorization: Bearer YOUR_AUTH_TOKEN_HERE"
      ]
    }
  }
}

Note: Replace YOUR_AUTH_TOKEN_HERE with your actual token. Do NOT use ${AUTH_TOKEN} syntax - Claude Desktop doesn't support environment variable substitution in args.

Method 2: Using Custom Bridge Script

For local testing or when mcp-remote isn't available:

{
  "mcpServers": {
    "n8n-local-http": {
      "command": "node",
      "args": [
        "/path/to/n8n-mcp/scripts/http-bridge.js"
      ],
      "env": {
        "MCP_URL": "http://localhost:3000/mcp",
        "AUTH_TOKEN": "your-auth-token-here"
      }
    }
  }
}

Local Development with Docker

When testing locally with Docker:

{
  "mcpServers": {
    "n8n-docker-http": {
      "command": "node",
      "args": [
        "/path/to/n8n-mcp/scripts/http-bridge.js"
      ],
      "env": {
        "MCP_URL": "http://localhost:3001/mcp",
        "AUTH_TOKEN": "docker-test-token"
      }
    }
  }
}

🔒 Security Features (v2.16.3+)

Rate Limiting

Built-in rate limiting protects authentication endpoints from brute force attacks:

Configuration:

# Defaults (15 minutes window, 20 attempts per IP)
AUTH_RATE_LIMIT_WINDOW=900000  # milliseconds
AUTH_RATE_LIMIT_MAX=20

Features:

• Per-IP rate limiting with configurable window and max attempts
• Standard rate limit headers (RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset)
• JSON-RPC formatted error responses
• Automatic IP tracking behind reverse proxies (requires TRUST_PROXY=1)

Behavior:

• First 20 attempts: Return 401 Unauthorized for invalid credentials
• Attempts 21+: Return 429 Too Many Requests with Retry-After header
• Counter resets after 15 minutes (configurable)

SSRF Protection

Prevents Server-Side Request Forgery attacks. The same gate applies to webhook trigger URLs (chat, form, generic webhook), the n8n API client base URL (N8N_API_URL), and per-request URLs supplied via the x-n8n-url header in multi-tenant mode.

Three Security Modes:

1. Strict Mode (default) - Production deployments

   WEBHOOK_SECURITY_MODE=strict
   

   • ✅ Block localhost (127.0.0.1, ::1)
   • ✅ Block private IPs (10.x, 192.168.x, 172.16-31.x)
   • ✅ Block cloud metadata (169.254.169.254, metadata.google.internal)
   • ✅ DNS rebinding prevention
   • 🎯 Use for: Cloud deployments, production environments

2. Moderate Mode - Local development with local n8n

   WEBHOOK_SECURITY_MODE=moderate
   

   • ✅ Allow localhost (for local n8n instances)
   • ✅ Block private IPs
   • ✅ Block cloud metadata
   • ✅ DNS rebinding prevention
   • 🎯 Use for: Development with n8n on localhost:5678

3. Permissive Mode - Internal networks only

   WEBHOOK_SECURITY_MODE=permissive
   

   • ✅ Allow localhost and private IPs
   • ✅ Block cloud metadata (always blocked)
   • ✅ DNS rebinding prevention
   • 🎯 Use for: Internal testing (NOT for production)

Important: Cloud metadata endpoints are ALWAYS blocked in all modes for security.

🔒 Security Best Practices

1. Token Management

DO:

• ✅ Use tokens with 32+ characters
• ✅ Store tokens in secure files or secrets management
• ✅ Rotate tokens regularly (monthly minimum)
• ✅ Use different tokens for each environment
• ✅ Monitor logs for authentication failures

DON'T:

• ❌ Use default or example tokens
• ❌ Commit tokens to version control
• ❌ Share tokens between environments
• ❌ Log tokens in plain text

# Generate strong token
openssl rand -base64 32

# Secure storage options:
# 1. Docker secrets (recommended)
echo $(openssl rand -base64 32) | docker secret create auth_token -

# 2. Kubernetes secrets
kubectl create secret generic n8n-mcp-auth \
  --from-literal=token=$(openssl rand -base64 32)

# 3. HashiCorp Vault
vault kv put secret/n8n-mcp token=$(openssl rand -base64 32)

2. Network Security

• ✅ Always use HTTPS in production
• ✅ Firewall rules to limit access
• ✅ VPN for internal deployments
• ✅ Rate limiting at proxy level

3. Container Security

# Run as non-root user (already configured)
# Read-only filesystem
docker run --read-only \
  --tmpfs /tmp \
  -v n8n-mcp-data:/app/data \
  n8n-mcp

# Security scanning
docker scan ghcr.io/czlonkowski/n8n-mcp:latest

🔍 Troubleshooting

Common Issues & Solutions

Authentication Issues

"Unauthorized" error:

# Check token is set correctly
docker exec n8n-mcp env | grep AUTH

# Test with curl
curl -v -H "Authorization: Bearer YOUR_TOKEN" \
     https://your-server.com/health

# Common causes:
# - Extra spaces in token
# - Missing "Bearer " prefix
# - Token file has newline at end
# - Wrong quotes in JSON config

Default token warning:

⚠️ SECURITY WARNING: Using default AUTH_TOKEN

• Change token immediately via environment variable
• Server shows this warning every 5 minutes

Connection Issues

"TransformStream is not defined":

# Check Node.js version on CLIENT machine
node --version  # Must be 18+

# Update Node.js
# macOS: brew upgrade node
# Linux: Use NodeSource repository
# Windows: Download from nodejs.org

"Cannot connect to server":

# 1. Check server is running
docker ps | grep n8n-mcp

# 2. Check logs for errors
docker logs n8n-mcp --tail 50

# 3. Test locally first
curl http://localhost:3000/health

# 4. Check firewall
sudo ufw status  # Linux

"Stream is not readable":

• This issue was fixed in v2.3.2+ with the SingleSessionHTTPServer
• No additional configuration needed

Bridge script not working:

# Test the bridge manually
export MCP_URL=http://localhost:3000/mcp
export AUTH_TOKEN=your-token
echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | node /path/to/http-bridge.js

Connection refused:

# Check server is running
curl http://localhost:3000/health

# Check Docker status
docker ps
docker logs n8n-mcp

# Check firewall
sudo ufw status

Authentication failed:

• Verify AUTH_TOKEN matches exactly
• Check for extra spaces or quotes
• Test with curl first

Bridge Configuration Issues

"Why use 'node' instead of 'docker' in Claude config?"

Claude Desktop only supports stdio. The architecture is:

Claude → stdio → mcp-remote → HTTP → Docker container

The node command runs mcp-remote (the bridge), not the server directly.

"Command not found: npx":

# Install Node.js 18+ which includes npx
# Or use full path:
which npx  # Find npx location
# Use that path in Claude config

Debug Mode

# 1. Enable debug logging
docker run -e LOG_LEVEL=debug ...

# 2. Test MCP endpoint
curl -X POST https://your-server.com/mcp \
  -H "Authorization: Bearer $AUTH_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/list",
    "id": 1
  }'

# 3. Test with mcp-remote directly
MCP_URL=https://your-server.com/mcp \
AUTH_TOKEN=your-token \
echo '{"jsonrpc":"2.0","method":"tools/list","id":1}' | \
  npx mcp-remote $MCP_URL --header "Authorization: Bearer $AUTH_TOKEN"

🔧 Using n8n Management Tools

When n8n API is configured, Claude can manage workflows directly:

Example: Create a Workflow via Claude

# Test n8n connectivity first
curl -X POST https://your-server.com/mcp \
  -H "Authorization: Bearer $AUTH_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "n8n_health_check",
    "params": {},
    "id": 1
  }'

Common Use Cases

1. Workflow Automation: Claude can create, update, and manage workflows
2. CI/CD Integration: Deploy workflows from version control
3. Workflow Templates: Claude can apply templates to new workflows
4. Monitoring: Track execution status and debug failures
5. Incremental Updates: Use diff-based updates for efficient changes

Security Best Practices for n8n API

• 🔐 Use separate API keys for different environments
• 🔄 Rotate API keys regularly
• 📝 Audit workflow changes via n8n's audit log
• 🚫 Never expose n8n API directly to the internet
• ✅ Use MCP server as a security layer

Read-Only Deployment Recipe

For governance-sensitive environments where the AI agent should be able to read workflow and execution data but must not modify or delete anything, combine two layers of control:

Layer 1 — MCP layer:

Some tools are write/destructive or handle sensitive data and should be removed entirely via DISABLED_TOOLS (n8n_manage_credentials and n8n_manage_datatable also offer read operations, but even their reads expose sensitive material):

DISABLED_TOOLS=n8n_create_workflow,n8n_update_full_workflow,n8n_update_partial_workflow,n8n_delete_workflow,n8n_autofix_workflow,n8n_deploy_template,n8n_test_workflow,n8n_manage_credentials,n8n_manage_datatable

Two tools bundle read and write operations under a single name. Use DISABLED_TOOL_OPERATIONS to block only their destructive branches while keeping list and get:

DISABLED_TOOL_OPERATIONS=n8n_workflow_versions:delete,rollback,prune;n8n_executions:delete

The operation parameter enum in the tool schema is updated to exclude disabled values, reducing the likelihood the model attempts them. Any attempt that does reach the server is rejected at dispatch before the handler runs.

Layer 2 — n8n API key RBAC:

Scope the N8N_API_KEY to read-only permissions in your n8n instance (Settings → API → create a key with read-only scope). This ensures that even if the MCP layer is misconfigured, the n8n API itself will reject destructive requests.

Both layers together provide defence in depth. The MCP layer is a convenience knob; the n8n API RBAC is the authoritative enforcement boundary.
