#### Transform your N8N workflows into MCP servers instantly
A comprehensive platform that converts N8N workflows into Model Context Protocol (MCP) servers, enabling seamless integration with AI assistants like Claude, Cursor, and other MCP-compatible platforms. Build powerful automation tools using N8N's visual workflow editor and deploy them as callable AI functions.
## ✨ How to use
1. Copy the N8N template link/JSON from any workflow
2. Map your credentials through our intuitive interface
3. Deploy with one click!
**Your N8N workflow gets deployed and creates a local hosted MCP server. Just paste the server URL into Claude, Cursor, Super Chain, or any MCP-compatible platform!**
## 🎯 Key Features
### 🤖 **MCP Server Creation**
Convert your N8N workflows into MCP servers that AI assistants can use as custom tools
### 🔄 **Dual Architecture**
- **Agent Marketplace**: Web-based workflow management and deployment platform
- **MCP Router**: High-performance MCP server creation and routing system
### 🛠️ **Comprehensive Workflow Management**
- Browse and deploy pre-built workflow templates
- Upload and manage your custom N8N workflows

2. **Import Template**: Enter an N8N template URL from n8n.io
3. **Configure Credentials**: Fill in required API keys and service credentials
4. **Deploy Workflow**: Click deploy to create the workflow in your N8N instance
5. **MCP Server Created**: Automatically generates an MCP server endpoint
#### Method 2: Upload Custom Workflows
1. **Upload JSON**: Upload your N8N workflow JSON file / Copy and paste your JSON workflow
2. **Review Analysis**: Check detected nodes and required credentials
3. **Configure & Deploy**: Fill credentials and deploy to N8N
4. **Access MCP Server**: Use the generated MCP endpoint in AI tools
#### Using MCP Servers
```bash
# Example MCP server URL format:
http://localhost:6545/mcp/{workflow_id}/{api_key}
# Test MCP server:
curl http://localhost:6545/list # List all registered MCP servers
```

### Database Setup
The system uses **2 main tables** in Supabase:
#### Setup
1. **Create Supabase Project**: Set up a new project at [supabase.com](https://supabase.com)
2. **Run SQL in Supabase SQL Editor**:
```sql
-- Main workflow storage table
CREATE TABLE IF NOT EXISTS public.user_workflows (
id UUID DEFAULT gen_random_uuid() PRIMARY KEY,
user_id TEXT NOT NULL,
template_id TEXT NOT NULL,
template_url TEXT NOT NULL,
workflow_name TEXT NOT NULL,
workflow_json JSONB NOT NULL,
workflow_description TEXT,
n8n_workflow_id TEXT,
source TEXT DEFAULT 'user_upload',
credentials_required JSONB DEFAULT '[]'::jsonb,
mcp_link TEXT,
status TEXT DEFAULT 'pending',
created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
);
-- MCP server configurations
CREATE TABLE IF NOT EXISTS public.mcp_configs (
id UUID DEFAULT gen_random_uuid() PRIMARY KEY,
workflow_id TEXT NOT NULL,
user_apikey TEXT NOT NULL,
code TEXT NOT NULL,
created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
UNIQUE(workflow_id, user_apikey)
);
-- Enable Row Level Security (recommended)
ALTER TABLE user_workflows ENABLE ROW LEVEL SECURITY;
ALTER TABLE mcp_configs ENABLE ROW LEVEL SECURITY;
```
## 🚀 Running the System
### Unified Startup (Recommended)
```bash
python main.py
```
This automatically starts both services with:
- ✅ Environment validation
- ✅ Database setup verification
- ✅ Graceful shutdown handling
- ✅ Centralized logging
### Individual Services
#### Agent Marketplace (Port 5000)
```bash
cd agent_marketplace
python app.py
```
#### MCP Router (Port 6545)
```bash
cd mcp_router
python mcp_router.py
```
### Verification
```bash
# Test Agent Marketplace
curl http://localhost:5000/api/health
# Test MCP Router
curl http://localhost:6545/list
# View all endpoints
curl http://localhost:5000/api/health | grep endpoints
```
## 🔧 Troubleshooting
### Common Issues
#### Port Already in Use
```bash
# Kill processes on ports 5000 and 6545
fuser -k 5000/tcp 6545/tcp
# Or restart with main.py which handles this automatically
python main.py
```
#### Database Connection Issues
```bash
# Verify Supabase configuration
python -c "from agent_marketplace.database import db_manager; print('✅ Database OK' if db_manager.supabase else '❌ Database connection failed')"
# Reset database tables
python agent_marketplace/setup_supabase.py
```
#### MCP Router Not Responding
```bash
# Check if MCP Router is running
curl http://localhost:6545/list
# View MCP Router logs
# Logs appear in terminal where main.py was started
```
#### N8N Workflow Creation Fails
- Verify `N8N_BASE_URL` includes `https://`
- Check `X_N8N_API_KEY` is valid and has workflow creation permissions
- Ensure N8N instance is accessible from your server
#### Missing Dependencies
```bash
# Install missing packages
pip install playwright
playwright install # For N8N authentication (required)
# Or install all dependencies
pip install -r requirements.txt
```
#### Playwright Browser Issues
```bash
# If playwright browsers fail to download
playwright install --force
# For headless environments (servers)
playwright install chromium
# Check if playwright is working
python -c "from playwright.async_api import async_playwright; print('✅ Playwright OK')"
```
### Development Tips
```bash
# Enable debug mode for Flask
export FLASK_DEBUG=1
# View detailed MCP Router logs
cd mcp_router && python mcp_router.py --log-level debug
# Test individual components
python -m agent_marketplace.n8n_workflow_parser # Test parser
python -m mcp_router.mcp_router # Test MCP Router
```
## 🔐 Security Best Practices
- **Credential Management**: Never store user credentials server-side
- **API Key Rotation**: Regularly rotate N8N API keys and Supabase keys
- **Network Security**: Use HTTPS in production with proper SSL certificates
- **Access Control**: Implement proper authentication and authorization
- **Data Isolation**: Ensure proper user data segregation with RLS policies
