feat: add n8n integration with MCP Client Tool support
- Add N8N_MODE environment variable for n8n-specific behavior - Implement HTTP Streamable transport with multiple session support - Add protocol version endpoint (GET /mcp) for n8n compatibility - Support multiple initialize requests for stateless n8n clients - Add Docker configuration for n8n deployment - Add test script with persistent volume support - Add comprehensive unit tests for n8n mode - Fix session management to handle per-request transport pattern BREAKING CHANGE: Server now creates new transport for each initialize request when running in n8n mode to support n8n's stateless client architecture 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# n8n MCP Client Tool Integration - Implementation Plan (Simplified)
|
||||
|
||||
## Overview
|
||||
|
||||
This document provides a **simplified** implementation plan for making n8n-mcp compatible with n8n's MCP Client Tool (v1.1). Based on expert review, we're taking a minimal approach that extends the existing single-session server rather than creating new architecture.
|
||||
|
||||
## Key Design Principles
|
||||
|
||||
1. **Minimal Changes**: Extend existing single-session server with n8n compatibility mode
|
||||
2. **No Overengineering**: No complex session management or multi-session architecture
|
||||
3. **Docker-Native**: Separate Docker image for n8n deployment
|
||||
4. **Remote Deployment**: Designed to run alongside n8n in production
|
||||
5. **Backward Compatible**: Existing functionality remains unchanged
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Docker and Docker Compose
|
||||
- n8n version 1.104.2 or higher (with MCP Client Tool v1.1)
|
||||
- Basic understanding of Docker networking
|
||||
|
||||
## Implementation Approach
|
||||
|
||||
Instead of creating new multi-session architecture, we'll extend the existing single-session server with an n8n compatibility mode. This approach was recommended by all three expert reviewers as simpler and more maintainable.
|
||||
|
||||
## Architecture Changes
|
||||
|
||||
```
|
||||
src/
|
||||
├── http-server-single-session.ts # MODIFY: Add n8n mode flag
|
||||
└── mcp/
|
||||
└── server.ts # NO CHANGES NEEDED
|
||||
|
||||
Docker/
|
||||
├── Dockerfile.n8n # NEW: n8n-specific image
|
||||
├── docker-compose.n8n.yml # NEW: Simplified stack
|
||||
└── .github/workflows/
|
||||
└── docker-build-n8n.yml # NEW: Build workflow
|
||||
```
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
### Step 1: Modify Existing Single-Session Server
|
||||
|
||||
#### 1.1 Update `src/http-server-single-session.ts`
|
||||
|
||||
Add n8n compatibility mode to the existing server with minimal changes:
|
||||
|
||||
```typescript
|
||||
// Add these constants at the top (after imports)
|
||||
const PROTOCOL_VERSION = "2024-11-05";
|
||||
const N8N_MODE = process.env.N8N_MODE === 'true';
|
||||
|
||||
// In the constructor or start method, add logging
|
||||
if (N8N_MODE) {
|
||||
logger.info('Running in n8n compatibility mode');
|
||||
}
|
||||
|
||||
// In setupRoutes method, add the protocol version endpoint
|
||||
if (N8N_MODE) {
|
||||
app.get('/mcp', (req, res) => {
|
||||
res.json({
|
||||
protocolVersion: PROTOCOL_VERSION,
|
||||
serverInfo: {
|
||||
name: "n8n-mcp",
|
||||
version: PROJECT_VERSION,
|
||||
capabilities: {
|
||||
tools: true,
|
||||
resources: false,
|
||||
prompts: false,
|
||||
},
|
||||
},
|
||||
});
|
||||
});
|
||||
}
|
||||
|
||||
// In handleMCPRequest method, add session header
|
||||
if (N8N_MODE && this.session) {
|
||||
res.setHeader('Mcp-Session-Id', this.session.sessionId);
|
||||
}
|
||||
|
||||
// Update error handling to use JSON-RPC format
|
||||
catch (error) {
|
||||
logger.error('MCP request error:', error);
|
||||
|
||||
if (N8N_MODE) {
|
||||
res.status(500).json({
|
||||
jsonrpc: '2.0',
|
||||
error: {
|
||||
code: -32603,
|
||||
message: 'Internal error',
|
||||
data: error instanceof Error ? error.message : 'Unknown error',
|
||||
},
|
||||
id: null,
|
||||
});
|
||||
} else {
|
||||
// Keep existing error handling for backward compatibility
|
||||
res.status(500).json({
|
||||
error: 'Internal server error',
|
||||
details: error instanceof Error ? error.message : 'Unknown error'
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
That's it! No new files, no complex session management. Just a few lines of code.
|
||||
|
||||
### Step 2: Update Package Scripts
|
||||
|
||||
#### 2.1 Update `package.json`
|
||||
|
||||
Add a simple script for n8n mode:
|
||||
|
||||
```json
|
||||
{
|
||||
"scripts": {
|
||||
"start:n8n": "N8N_MODE=true MCP_MODE=http node dist/mcp/index.js"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Step 3: Create Docker Infrastructure for n8n
|
||||
|
||||
#### 3.1 Create `Dockerfile.n8n`
|
||||
|
||||
```dockerfile
|
||||
# Dockerfile.n8n - Optimized for n8n integration
|
||||
FROM node:22-alpine AS builder
|
||||
|
||||
WORKDIR /app
|
||||
|
||||
# Install build dependencies
|
||||
RUN apk add --no-cache python3 make g++
|
||||
|
||||
# Copy package files
|
||||
COPY package*.json tsconfig*.json ./
|
||||
|
||||
# Install ALL dependencies
|
||||
RUN npm ci --no-audit --no-fund
|
||||
|
||||
# Copy source and build
|
||||
COPY src ./src
|
||||
RUN npm run build && npm run rebuild
|
||||
|
||||
# Runtime stage
|
||||
FROM node:22-alpine
|
||||
|
||||
WORKDIR /app
|
||||
|
||||
# Install runtime dependencies
|
||||
RUN apk add --no-cache curl dumb-init
|
||||
|
||||
# Create non-root user
|
||||
RUN addgroup -g 1001 -S nodejs && adduser -S nodejs -u 1001
|
||||
|
||||
# Copy application from builder
|
||||
COPY --from=builder --chown=nodejs:nodejs /app/dist ./dist
|
||||
COPY --from=builder --chown=nodejs:nodejs /app/data ./data
|
||||
COPY --from=builder --chown=nodejs:nodejs /app/node_modules ./node_modules
|
||||
COPY --chown=nodejs:nodejs package.json ./
|
||||
|
||||
USER nodejs
|
||||
|
||||
EXPOSE 3001
|
||||
|
||||
HEALTHCHECK CMD curl -f http://localhost:3001/health || exit 1
|
||||
|
||||
ENTRYPOINT ["dumb-init", "--"]
|
||||
CMD ["node", "dist/mcp/index.js"]
|
||||
```
|
||||
|
||||
#### 3.2 Create `docker-compose.n8n.yml`
|
||||
|
||||
```yaml
|
||||
# docker-compose.n8n.yml - Simple stack for n8n + n8n-mcp
|
||||

|
||||
- N8N_BASIC_AUTH_USER=${N8N_USER:-admin}
|
||||
- N8N_BASIC_AUTH_PASSWORD=${N8N_PASSWORD:-changeme}
|
||||
- N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=true
|
||||
volumes:

|
||||
depends_on:
|
||||
n8n-mcp:

|
||||
|
||||
n8n-mcp:
|
||||

|
||||
build:
|
||||
context: .
|
||||
dockerfile: Dockerfile.n8n
|
||||
container_name: n8n-mcp
|
||||
restart: unless-stopped
|
||||
environment:
|
||||
- MCP_MODE=http
|
||||
- N8N_MODE=true
|
||||
- AUTH_TOKEN=${MCP_AUTH_TOKEN}
|
||||
- NODE_ENV=production
|
||||
- HTTP_PORT=3001
|
||||
networks:
|
||||
- n8n-net
|
||||
healthcheck:
|
||||
test: ["CMD", "curl", "-f", "http://localhost:3001/health"]
|
||||
interval: 30s
|
||||

|
||||
retries: 3
|
||||
|
||||

||||
driver: bridge
|
||||
|
||||
volumes:
|
||||
n8n_data:
|
||||
```
|
||||
|
||||
#### 3.3 Create `.env.n8n.example`
|
||||
|
||||
```bash
|
||||
# .env.n8n.example - Copy to .env and configure
|
||||
|
||||
# n8n Configuration
|
||||
N8N_USER=admin
|
||||
N8N_PASSWORD=changeme
|
||||
N8N_BASIC_AUTH_ACTIVE=true
|
||||
|
||||
# MCP Configuration
|
||||
# Generate with: openssl rand -base64 32
|
||||
MCP_AUTH_TOKEN=your-secure-token-minimum-32-characters
|
||||
|
||||
# GitHub username for image registry
|
||||
GITHUB_USER=czlonkowski
|
||||
```
|
||||
|
||||
### Step 4: Create GitHub Actions Workflow
|
||||
|
||||
#### 4.1 Create `.github/workflows/docker-build-n8n.yml`
|
||||
|
||||
```yaml
|
||||

|
||||
|
||||

|
||||
push:

```
|
||||
|
||||
### Step 5: Testing
|
||||
|
||||
#### 5.1 Unit Tests for n8n Mode
|
||||
|
||||
Create `tests/unit/http-server-n8n-mode.test.ts`:
|
||||
|
||||
```typescript
|
||||
import { describe, it, expect, vi } from 'vitest';
|
||||
import request from 'supertest';
|
||||
|
||||
describe('n8n Mode', () => {
|
||||
it('should return protocol version on GET /mcp', async () => {
|
||||
process.env.N8N_MODE = 'true';
|
||||
const app = await createTestApp();
|
||||
|
||||
const response = await request(app)
|
||||
.get('/mcp')
|
||||
.expect(200);
|
||||
|
||||
expect(response.body.protocolVersion).toBe('2024-11-05');
|
||||
expect(response.body.serverInfo.capabilities.tools).toBe(true);
|
||||
});
|
||||
|
||||
it('should include session ID in response headers', async () => {
|
||||
process.env.N8N_MODE = 'true';
|
||||
const app = await createTestApp();
|
||||
|
||||
const response = await request(app)
|
||||
.post('/mcp')
|
||||
.set('Authorization', 'Bearer test-token')
|
||||
.send({ jsonrpc: '2.0', method: 'initialize', id: 1 });
|
||||
|
||||
expect(response.headers['mcp-session-id']).toBeDefined();
|
||||
});
|
||||
|
||||
it('should format errors as JSON-RPC', async () => {
|
||||
process.env.N8N_MODE = 'true';
|
||||
const app = await createTestApp();
|
||||
|
||||
const response = await request(app)
|
||||
.post('/mcp')
|
||||
.send({ invalid: 'request' })
|
||||
.expect(500);
|
||||
|
||||
expect(response.body.jsonrpc).toBe('2.0');
|
||||
expect(response.body.error.code).toBe(-32603);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
#### 5.2 Quick Deployment Script
|
||||
|
||||
Create `deploy/quick-deploy-n8n.sh`:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
|
||||
echo "🚀 Quick Deploy n8n + n8n-mcp"
|
||||
|
||||
# Check prerequisites
|
||||
command -v docker >/dev/null 2>&1 || { echo "Docker required"; exit 1; }
|
||||
command -v docker-compose >/dev/null 2>&1 || { echo "Docker Compose required"; exit 1; }
|
||||
|
||||
# Generate auth token if not exists
|
||||
if [ ! -f .env ]; then
|
||||
cp .env.n8n.example .env
|
||||
TOKEN=$(openssl rand -base64 32)
|
||||
sed -i "s/your-secure-token-minimum-32-characters/$TOKEN/" .env
|
||||
echo "Generated MCP_AUTH_TOKEN: $TOKEN"
|
||||
fi
|
||||
|
||||
# Deploy
|
||||
docker-compose -f docker-compose.n8n.yml up -d
|
||||
|
||||
echo ""
|
||||
echo "✅ Deployment complete!"
|
||||
echo ""
|
||||
echo "📋 Next steps:"
|
||||
echo "1. Access n8n at http://localhost:5678"
|
||||
echo " Username: admin (or check .env)"
|
||||
echo " Password: changeme (or check .env)"
|
||||
echo ""
|
||||
echo "2. Create a workflow with MCP Client Tool:"

## Implementation Checklist (Simplified)
|
||||
|
||||
### Code Changes
|
||||
- [ ] Add N8N_MODE flag to `http-server-single-session.ts`
|
||||
- [ ] Add protocol version endpoint (GET /mcp) when N8N_MODE=true
|
||||
- [ ] Add Mcp-Session-Id header to responses
|
||||
- [ ] Update error responses to JSON-RPC format when N8N_MODE=true
|
||||
- [ ] Add npm script `start:n8n` to package.json
|
||||
|
||||
### Docker Infrastructure
|
||||
- [ ] Create `Dockerfile.n8n` for n8n-specific image
|
||||
- [ ] Create `docker-compose.n8n.yml` for simple deployment
|
||||
- [ ] Create `.env.n8n.example` template
|
||||
- [ ] Create GitHub Actions workflow `docker-build-n8n.yml`
|
||||
- [ ] Create `deploy/quick-deploy-n8n.sh` script
|
||||
|
||||
### Testing
|
||||
- [ ] Write unit tests for n8n mode functionality
|
||||
- [ ] Test with actual n8n MCP Client Tool
|
||||
- [ ] Verify protocol version endpoint
|
||||
- [ ] Test authentication flow
|
||||
- [ ] Validate error formatting
|
||||
|
||||
### Documentation
|
||||
- [ ] Update README with n8n deployment section
|
||||
- [ ] Document N8N_MODE environment variable
|
||||
- [ ] Add troubleshooting guide for common issues
|
||||
|
||||
## Quick Start Guide
|
||||
|
||||
### 1. One-Command Deployment
|
||||
|
||||
```bash
|
||||
# Clone and deploy
|
||||
git clone https://github.com/czlonkowski/n8n-mcp.git
|
||||
cd n8n-mcp
|
||||
./deploy/quick-deploy-n8n.sh
|
||||
```
|
||||
|
||||
### 2. Manual Configuration in n8n
|
||||
|
||||
After deployment, configure the MCP Client Tool in n8n:
|
||||
|
||||
1. Open n8n at `http://localhost:5678`
|
||||
2. Create a new workflow
|
||||
3. Add "MCP Client Tool" node (under AI category)
|
||||
4. Configure:
|
||||
- **Server URL**: `http://n8n-mcp:3001/mcp`
|
||||
- **Authentication**: Bearer Token
|
||||
- **Token**: Check your `.env` file for MCP_AUTH_TOKEN
|
||||
5. Select a tool (e.g., `list_nodes`)
|
||||
6. Execute the workflow
|
||||
|
||||
### 3. Production Deployment
|
||||
|
||||
For production with SSL, use a reverse proxy:
|
||||
|
||||
```nginx
|
||||
# nginx configuration
|
||||
server {
|
||||
listen 443 ssl;
|
||||
server_name n8n.yourdomain.com;
|
||||
|
||||
location / {
|
||||
proxy_pass http://localhost:5678;
|
||||
proxy_http_version 1.1;
|
||||
proxy_set_header Upgrade $http_upgrade;
|
||||
proxy_set_header Connection "upgrade";
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The MCP server should remain internal only - n8n connects via Docker network.
|
||||
|
||||
## Success Criteria
|
||||
|
||||
The implementation is successful when:
|
||||
|
||||
1. **Minimal Code Changes**: Only ~20 lines added to existing server
|
||||
2. **Protocol Compliance**: GET /mcp returns correct protocol version
|
||||
3. **n8n Connection**: MCP Client Tool connects successfully
|
||||
4. **Tool Execution**: Tools work without modification
|
||||
5. **Backward Compatible**: Existing Claude Desktop usage unaffected
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **"Protocol version mismatch"**
|
||||
- Ensure N8N_MODE=true is set
|
||||
- Check GET /mcp returns "2024-11-05"
|
||||
|
||||
2. **"Authentication failed"**
|
||||
- Verify AUTH_TOKEN matches in .env and n8n
|
||||
- Token must be 32+ characters
|
||||
- Use "Bearer Token" auth type in n8n
|
||||
|
||||
3. **"Connection refused"**
|
||||
- Check containers are on same network
|
||||
- Use internal hostname: `http://n8n-mcp:3001/mcp`
|
||||
- Verify health check passes
|
||||
|
||||
4. **Testing the Setup**
|
||||
```bash
|
||||
# Check protocol version
|
||||
docker exec n8n-mcp curl http://localhost:3001/mcp
|
||||
|
||||
# View logs
|
||||
docker-compose -f docker-compose.n8n.yml logs -f n8n-mcp
|
||||
```
|
||||
|
||||
## Summary
|
||||
|
||||
This simplified approach:
|
||||
- **Extends existing code** rather than creating new architecture
|
||||
- **Adds n8n compatibility** with minimal changes
|
||||
- **Uses separate Docker image** for clean deployment
|
||||
- **Maintains backward compatibility** for existing users
|
||||
- **Avoids overengineering** with simple, practical solutions
|
||||
|
||||
Total implementation effort: ~2-3 hours (vs. 2-3 days for multi-session approach)
