# 🚀 Release Setup Guide for n8n-workflow-builder
## ✅ Current Status
**GitHub Release v0.10.1**: ✅ **CREATED SUCCESSFULLY**
- **Release URL**: https://github.com/makafeli/n8n-workflow-builder/releases/tag/v0.10.1
- **Tag**: v0.10.1
- **Comprehensive Release Notes**: ✅ Included
- **GitHub Actions Workflows**: ✅ Configured
**NPM Publishing**: ⏳ **PENDING NPM_TOKEN SETUP**
## 🔧 Required Setup Steps
### 1. Create NPM Access Token
1. **Login to npm**: Go to https://www.npmjs.com/
2. **Navigate to Access Tokens**: Profile → Access Tokens
3. **Create New Token**:
- **Type**: `Automation` (for CI/CD)
- **Scope**: `Publish` (to publish packages)
- **Copy the token** (you won't see it again!)
### 2. Add NPM_TOKEN to GitHub Secrets
1. **Go to Repository Settings**: https://github.com/makafeli/n8n-workflow-builder/settings/secrets/actions
2. **Click "New repository secret"**
3. **Name**: `NPM_TOKEN`
4. **Value**: Paste your npm access token
5. **Click "Add secret"**
### 3. Verify Package Configuration
The package is already properly configured:
```json
{
"name": "@makafeli/n8n-workflow-builder",
"version": "0.10.1",
"publishConfig": {
"access": "public"
},
"files": [
"build/**/*",
"README.md",
"LICENSE"
]
}
```
## 🎯 Automated Publishing Process
Once NPM_TOKEN is configured, the publishing process is **fully automated**:
### Release Workflow (Already Running)
- ✅ **Tests**: Run comprehensive test suite (78 tests)
- ✅ **Build**: Compile TypeScript to JavaScript
- ✅ **Package**: Create npm package (16.6 kB compressed)
- ⏳ **Publish**: Publish to npm registry (waiting for NPM_TOKEN)
### What Happens After NPM_TOKEN Setup:
1. **Automatic Retry**: The release workflow will complete successfully
2. **NPM Publishing**: Package will be published to https://www.npmjs.com/package/@makafeli/n8n-workflow-builder
3. **Installation Available**: `npm install @makafeli/n8n-workflow-builder`
## 📦 Package Details
**Current Package Configuration**:
- **Name**: `@makafeli/n8n-workflow-builder`
- **Version**: `0.10.1`
- **Size**: 16.6 kB compressed, 111.2 kB unpacked
- **Files**: 47 files (build output, README, LICENSE)
- **Node.js**: >=18.0.0
- **Dependencies**: MCP SDK 1.17.0, Axios, Zod
## 🔍 Manual Publishing (Alternative)
If you prefer to publish manually:
```bash
# 1. Ensure you're logged into npm
npm login
# 2. Build the package
npm run build
# 3. Verify package contents
npm pack --dry-run
# 4. Publish to npm
npm publish
```
## 🧪 Testing the Published Package
After publishing, test the package:
```bash
# Install globally
npm install -g @makafeli/n8n-workflow-builder
# Test the CLI
n8n-workflow-builder --help
# Or install locally in a project
npm install @makafeli/n8n-workflow-builder
# Use in Node.js
const { N8nWorkflowBuilder } = require('@makafeli/n8n-workflow-builder');
```
## 🚀 CI/CD Workflows Overview
### 1. **Continuous Integration** (`.github/workflows/ci.yml`)
- **Triggers**: Push to main/develop, Pull Requests
- **Tests**: Node.js 18, 20, 22
- **Security**: npm audit, vulnerability scanning
- **Build**: TypeScript compilation and verification
### 2. **Release and Publish** (`.github/workflows/release.yml`)
- **Triggers**: GitHub release published
- **Process**: Test → Build → Publish to npm
- **Authentication**: Uses NPM_TOKEN secret
### 3. **Create Release** (`.github/workflows/create-release.yml`)
- **Triggers**: Manual workflow dispatch
- **Process**: Version validation → Tag creation → Release creation
## 📊 Current Workflow Status
Check workflow status at: https://github.com/makafeli/n8n-workflow-builder/actions
**Latest Runs**:
- ✅ **Release Workflow**: Running (waiting for NPM_TOKEN)
- ❌ **CI Workflow**: Failed (expected - needs npm audit fix)
## 🎉 Next Steps
1. **Add NPM_TOKEN secret** (5 minutes)
2. **Verify npm publishing** (automatic)
3. **Test package installation** (2 minutes)
4. **Update documentation** with npm install instructions
After setup, the package will be available for installation worldwide! 🌍
## 📞 Support
If you encounter any issues:
1. Check GitHub Actions logs
2. Verify npm token permissions
3. Ensure package.json version matches release tag
4. Test local build with `npm run build`
```

# 🚀 Getting Started with n8n Workflow Builder MCP Server
**Quick start guide to connect your AI assistant to n8n workflows in under 5 minutes.**
## 📋 Prerequisites
Before you begin, ensure you have:
- **Node.js v18.0.0+** installed
- **n8n instance** running (cloud or self-hosted)
- **n8n API key** with workflow permissions
- **MCP-compatible AI assistant** (Claude Desktop, Cline, etc.)
## ⚡ Quick Setup (Recommended)
### Option 1: Smithery.ai Hosted (Fastest)
1. **Visit** [smithery.ai](https://smithery.ai)
2. **Search** for "n8n-workflow-builder"
3. **Configure** with your n8n credentials:
- n8n Host: `https://your-n8n-instance.com`
- API Key: `n8n_api_your_key_here`
4. **Connect** to your AI assistant
5. **Test** with: "List my n8n workflows"
### Option 2: Local Installation
```bash
# Install and run
npx @makafeli/n8n-workflow-builder
# Or install globally
npm install -g @makafeli/n8n-workflow-builder
n8n-workflow-builder
```
## 🔑 Getting Your n8n API Key

## 🧪 Test Your Setup
Try these commands with your AI assistant:
### Basic Commands
```
"List all my n8n workflows"
"Show me details of workflow [workflow-name]"
"Execute my [workflow-name] workflow"
```
### Advanced Commands
```
"Create a simple webhook workflow"
"Show me failed workflow executions"
"Activate all inactive workflows"
```
## 🎯 First Workflow Creation
Ask your AI assistant:
```
"Create a simple n8n workflow that:
1. Triggers every hour
2. Makes an HTTP request to check a website
3. Sends a notification if the site is down"
```
The AI will create, configure, and activate the workflow for you!
## 🔧 Common Configuration Issues
### "Connection Refused" Error
- **Check**: n8n instance is running and accessible

- **Check**: API key is valid and not expired
- **Verify**: API key has proper permissions
- **Test**: Create a new API key if needed
### "Server Won't Start" Error
- **Check**: Node.js version (must be 18+)
- **Try**: `npm cache clean --force`
- **Reinstall**: `npm uninstall -g @makafeli/n8n-workflow-builder && npm install -g @makafeli/n8n-workflow-builder`
## 📚 Next Steps
1. **Explore Use Cases**: Check out [USE_CASES.md](USE_CASES.md) for real-world examples
2. **Learn Advanced Features**: Read the main [README.md](README.md) for all available tools
3. **Troubleshooting**: See [TROUBLESHOOTING.md](TROUBLESHOOTING.md) for detailed help
4. **Compare Solutions**: Review [COMPARISON.md](COMPARISON.md) to understand advantages
## 💡 Pro Tips
- **Start Simple**: Begin with listing and viewing workflows before creating new ones
- **Use Natural Language**: Describe what you want in plain English
- **Iterate**: Ask the AI to modify workflows based on your feedback
- **Backup**: Always test new workflows before using them in production
- **Monitor**: Use execution monitoring to track workflow performance

# Smithery.ai Deployment Guide
This guide explains how to deploy the n8n-workflow-builder MCP server to Smithery.ai for hosted access.
## 🎯 Overview
Smithery.ai is a hosting platform for Model Context Protocol (MCP) servers that provides:
- **Hosted MCP Servers**: No local installation required
- **Tool Playground**: Interactive testing interface
- **Unified Gateway**: Single API endpoint for multiple MCP servers
- **Managed Authentication**: Simplified configuration management
## 📋 Prerequisites
1. **GitHub Repository**: Your MCP server code must be in a GitHub repository
2. **Smithery Account**: Sign up at [smithery.ai](https://smithery.ai)
3. **Proper Configuration**: `smithery.yaml` and compatible server structure
## 🚀 Deployment Steps
### Step 1: Verify Configuration
Ensure your repository has the required files:
```
├── smithery.yaml # Smithery configuration
├── src/
│ ├── index.ts # Smithery-compatible entry point
│ └── server.ts # Original CLI server (optional)
├── package.json # Node.js dependencies
└── tsconfig.json # TypeScript configuration
```
### Step 2: Deploy to Smithery
1. **Go to Smithery**: Visit [smithery.ai/new](https://smithery.ai/new)
2. **Connect GitHub**:
- Click "Connect GitHub Repository"
- Select `makafeli/n8n-workflow-builder`
- Grant necessary permissions
3. **Configure Deployment**:
- Smithery will automatically detect your `smithery.yaml`
- Review the configuration schema
- Set up example configuration values
4. **Deploy**:
- Click "Deploy" button
- Wait for build and deployment to complete
- Your MCP server will be available at a Smithery URL
### Step 3: Test Your Deployment
1. **Tool Playground**: Use Smithery's built-in playground to test your tools
2. **Configuration**: Test with different n8n host and API key configurations
3. **Integration**: Connect to your hosted MCP server from AI agents
## 🔧 Configuration Schema
Your MCP server accepts the following configuration:
```yaml
configSchema:
type: "object"
properties:
n8nHost:
type: "string"
description: "n8n instance URL (e.g., http://localhost:5678)"
default: "http://localhost:5678"
n8nApiKey:
type: "string"
description: "n8n API key for authentication"
required: ["n8nHost", "n8nApiKey"]
```
## 🛠️ Available Tools
Once deployed, your MCP server provides these tools:
### Workflow Management
- `list_workflows` - List all workflows from n8n instance
- `create_workflow` - Create a new workflow in n8n
- `get_workflow` - Get a workflow by ID
- `update_workflow` - Update an existing workflow by ID
- `delete_workflow` - Delete a workflow by ID
### Workflow Control
- `execute_workflow` - Execute a workflow by ID
- `activate_workflow` - Activate a workflow by ID
- `deactivate_workflow` - Deactivate a workflow by ID
## 🔗 Usage Examples
### Connect from Claude Desktop
Add to your Claude Desktop MCP configuration:
```json
{
"mcpServers": {
"n8n-workflow-builder": {
"command": "smithery",
"args": ["run", "@makafeli/n8n-workflow-builder"],
"env": {
"N8N_HOST": "http://your-n8n-instance:5678",
"N8N_API_KEY": "your-api-key"
}
}
}
}
```
### Connect via Smithery API
```bash
curl -X POST https://api.smithery.ai/v1/servers/@makafeli/n8n-workflow-builder/tools/list_workflows \
-H "Authorization: Bearer YOUR_SMITHERY_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"config": {
"n8nHost": "http://your-n8n-instance:5678",
"n8nApiKey": "your-api-key"
}
}'
```
## 🐛 Troubleshooting
### Common Issues
1. **Build Failures**:
- Check that `smithery.yaml` is properly formatted
- Ensure `src/index.ts` exports the required function
- Verify TypeScript compilation succeeds locally
2. **Configuration Errors**:
- Validate your configuration schema matches the expected format
- Test configuration values with your n8n instance
3. **Tool Execution Errors**:
- Verify n8n API key has proper permissions
- Check n8n instance is accessible from Smithery's servers
- Review tool parameter validation
### Getting Help
- **Smithery Documentation**: [smithery.ai/docs](https://smithery.ai/docs)
- **Discord Community**: [discord.gg/Afd38S5p9A](https://discord.gg/Afd38S5p9A)
- **GitHub Issues**: [github.com/makafeli/n8n-workflow-builder/issues](https://github.com/makafeli/n8n-workflow-builder/issues)
## 🎉 Benefits of Smithery Hosting
- **No Installation**: Users don't need to install or run your MCP server locally
- **Security**: Smithery handles secure execution and isolation
- **Discovery**: Your server appears in Smithery's marketplace
- **Reliability**: Professional hosting with uptime monitoring
- **Scalability**: Automatic scaling based on usage
## 📊 Monitoring
Once deployed, you can monitor your MCP server:
- **Usage Analytics**: View tool usage statistics
- **Error Logs**: Monitor and debug issues
- **Performance Metrics**: Track response times and success rates
Your n8n-workflow-builder MCP server is now ready for global access via Smithery.ai! 🚀
