398 | ## 🔧 Troubleshooting
399 |
400 | ### Common Issues
401 |
402 | #### "Connection refused" or "ECONNREFUSED"
403 | - **Cause**: Cannot connect to your n8n instance
404 | - **Solution**: Verify your `N8N_HOST` is correct and n8n is running
405 | - **Check**: Try accessing your n8n instance in a browser first
406 |
407 | #### "Unauthorized" or "401 Error"
408 | - **Cause**: Invalid or missing API key
409 | - **Solution**:
410 | 1. Verify your `N8N_API_KEY` is correct
411 | 2. Ensure the API key has proper permissions
412 | 3. Check if the API key hasn't expired
413 |
414 | #### "Workflow not found" or "404 Error"
415 | - **Cause**: Workflow ID doesn't exist
416 | - **Solution**: Use `list_workflows` to get valid workflow IDs
417 |
418 | #### Server won't start
419 | - **Cause**: Missing Node.js or dependencies
420 | - **Solution**:
421 | 1. Ensure Node.js v18+ is installed: `node --version`
422 | 2. Try clearing npm cache: `npm cache clean --force`
423 | 3. For manual installation, run: `npm install && npm run build`
424 |
425 | ### Debug Mode
426 |
427 | For detailed logging, set the debug environment variable:
428 |
429 | ```bash
430 | DEBUG=n8n-workflow-builder npx @makafeli/n8n-workflow-builder
431 | ```
432 |
433 | ### Getting Help
434 |
435 | 1. Check the [GitHub Issues](https://github.com/makafeli/n8n-workflow-builder/issues)
436 | 2. Review n8n's [API documentation](https://docs.n8n.io/api/)
437 | 3. Verify your MCP client configuration
438 |
439 | ## ❓ Frequently Asked Questions
440 |
441 | ### What is an MCP Server?
442 |
443 | A **Model Context Protocol (MCP) server** is a standardized way for AI assistants to access external tools and data sources. This MCP server specifically provides AI assistants with the ability to interact with n8n workflows, enabling automated workflow management through natural language commands.
444 |
445 | ### How do I connect AI assistants to n8n workflows?
446 |
447 | This MCP server acts as a bridge between AI assistants (like Claude Desktop, Cline, or ChatGPT) and your n8n instance. Simply:
448 | 1. Install the MCP server: `npx @makafeli/n8n-workflow-builder`
449 | 2. Configure your AI assistant's MCP settings with your n8n credentials
450 | 3. Start using natural language to manage your n8n workflows
451 |
452 | ### Which AI assistants work with this MCP server?
453 |
454 | The server works with any **MCP-compatible AI assistant**, including:
455 | - **Claude Desktop** (Anthropic)
456 | - **Cline** (VS Code extension)
457 | - **Continue** (VS Code extension)
458 | - Any custom MCP client implementation
459 | - Future MCP-compatible AI assistants
460 |
461 | ### Can I use this with n8n Cloud or only self-hosted?
462 |
463 | This MCP server works with **both n8n Cloud and self-hosted instances**. You just need:
464 | - Your n8n instance URL (cloud or self-hosted)
465 | - A valid n8n API key with appropriate permissions
466 | - Network access from where you're running the MCP server
467 |
468 | ### What can AI assistants do with my n8n workflows?
469 |
470 | AI assistants can perform **complete workflow management** including:
471 | - **List and browse** existing workflows
472 | - **Create new workflows** with complex node configurations
473 | - **Execute workflows** manually or on-demand
474 | - **Activate/deactivate** workflows
475 | - **Update and modify** existing workflows
476 | - **Monitor execution status** and retrieve detailed logs
477 | - **Manage workflow tags** and organization
478 | - **Generate security audits** and compliance reports
479 |
480 | ### Is this secure? What permissions does it need?
481 |
482 | The MCP server uses **n8n's official API** with proper authentication:
483 | - Requires a valid n8n API key (you control the permissions)
484 | - No data is stored by the MCP server
485 | - All communication is direct between your AI assistant and n8n
486 | - Follows n8n's security model and access controls
487 | - You can revoke access anytime by disabling the API key
488 |
489 | ### How is this different from using n8n's web interface?
490 |
491 | This MCP server enables **AI-powered workflow management**:
492 | - **Natural language commands** instead of clicking through UI
493 | - **Automated workflow creation** based on descriptions
494 | - **Bulk operations** across multiple workflows
495 | - **Integration with AI assistant workflows** and automation
496 | - **Voice commands** through AI assistants
497 | - **Contextual help** and suggestions from AI
498 |
499 | 🔍 **Detailed Comparison**: See our [Comparison Guide](COMPARISON.md) for detailed comparisons with n8n Web UI, CLI, Zapier, and Make.com.
500 |
501 | ### Can I automate workflow creation with AI?
502 |
503 | Yes! This is one of the key features. You can:
504 | - **Describe workflows in natural language** and have AI create them
505 | - **Generate workflows from requirements** or use cases
506 | - **Modify existing workflows** through conversational commands
507 | - **Create workflow templates** and variations automatically
508 | - **Batch create similar workflows** with different parameters
509 |
510 | 💼 **Real Examples**: Check out our [Use Cases Guide](USE_CASES.md) for specific automation examples across different industries.
511 |
512 | ### What if I encounter issues or errors?

1 | # 🚀 Release Setup Guide for n8n-workflow-builder
2 |
3 | ## ✅ Current Status
4 |
5 | **GitHub Release v0.10.1**: ✅ **CREATED SUCCESSFULLY**
6 | - **Release URL**: https://github.com/makafeli/n8n-workflow-builder/releases/tag/v0.10.1
7 | - **Tag**: v0.10.1
8 | - **Comprehensive Release Notes**: ✅ Included
9 | - **GitHub Actions Workflows**: ✅ Configured
10 |
11 | **NPM Publishing**: ⏳ **PENDING NPM_TOKEN SETUP**
12 |
13 | ## 🔧 Required Setup Steps
14 |
15 | ### 1. Create NPM Access Token
16 |
17 | 1. **Login to npm**: Go to https://www.npmjs.com/
18 | 2. **Navigate to Access Tokens**: Profile → Access Tokens
19 | 3. **Create New Token**:
20 | - **Type**: `Automation` (for CI/CD)
21 | - **Scope**: `Publish` (to publish packages)
22 | - **Copy the token** (you won't see it again!)
23 |
24 | ### 2. Add NPM_TOKEN to GitHub Secrets
25 |
26 | 1. **Go to Repository Settings**: https://github.com/makafeli/n8n-workflow-builder/settings/secrets/actions
27 | 2. **Click "New repository secret"**
28 | 3. **Name**: `NPM_TOKEN`
29 | 4. **Value**: Paste your npm access token
30 | 5. **Click "Add secret"**
31 |
32 | ### 3. Verify Package Configuration
33 |
34 | The package is already properly configured:
35 |
36 | ```json
37 | {
38 | "name": "@makafeli/n8n-workflow-builder",
39 | "version": "0.10.1",
40 | "publishConfig": {
41 | "access": "public"
42 | },
43 | "files": [
44 | "build/**/*",
45 | "README.md",
46 | "LICENSE"
47 | ]
48 | }
49 | ```
50 |
51 | ## 🎯 Automated Publishing Process
52 |
53 | Once NPM_TOKEN is configured, the publishing process is **fully automated**:
54 |
55 | ### Release Workflow (Already Running)
56 | - ✅ **Tests**: Run comprehensive test suite (78 tests)
57 | - ✅ **Build**: Compile TypeScript to JavaScript
58 | - ✅ **Package**: Create npm package (16.6 kB compressed)
59 | - ⏳ **Publish**: Publish to npm registry (waiting for NPM_TOKEN)
60 |
61 | ### What Happens After NPM_TOKEN Setup:
62 | 1. **Automatic Retry**: The release workflow will complete successfully
63 | 2. **NPM Publishing**: Package will be published to https://www.npmjs.com/package/@makafeli/n8n-workflow-builder
64 | 3. **Installation Available**: `npm install @makafeli/n8n-workflow-builder`
65 |

1 | # Smithery.ai Deployment Guide
2 |
3 | This guide explains how to deploy the n8n-workflow-builder MCP server to Smithery.ai for hosted access.
4 |
5 | ## 🎯 Overview
6 |
7 | Smithery.ai is a hosting platform for Model Context Protocol (MCP) servers that provides:
8 | - **Hosted MCP Servers**: No local installation required
9 | - **Tool Playground**: Interactive testing interface
10 | - **Unified Gateway**: Single API endpoint for multiple MCP servers
11 | - **Managed Authentication**: Simplified configuration management
12 |
13 | ## 📋 Prerequisites
14 |
15 | 1. **GitHub Repository**: Your MCP server code must be in a GitHub repository
16 | 2. **Smithery Account**: Sign up at [smithery.ai](https://smithery.ai)
17 | 3. **Proper Configuration**: `smithery.yaml` and compatible server structure
18 |
19 | ## 🚀 Deployment Steps
20 |
21 | ### Step 1: Verify Configuration
22 |
23 | Ensure your repository has the required files:
24 |
25 | ```
26 | ├── smithery.yaml # Smithery configuration
27 | ├── src/
28 | │ ├── index.ts # Smithery-compatible entry point
29 | │ └── server.ts # Original CLI server (optional)
30 | ├── package.json # Node.js dependencies
31 | └── tsconfig.json # TypeScript configuration
32 | ```
33 |
34 | ### Step 2: Deploy to Smithery
35 |
36 | 1. **Go to Smithery**: Visit [smithery.ai/new](https://smithery.ai/new)
37 |
38 | 2. **Connect GitHub**:
39 | - Click "Connect GitHub Repository"
40 | - Select `makafeli/n8n-workflow-builder`
41 | - Grant necessary permissions
42 |
43 | 3. **Configure Deployment**:
44 | - Smithery will automatically detect your `smithery.yaml`
45 | - Review the configuration schema
46 | - Set up example configuration values
47 |
48 | 4. **Deploy**:
49 | - Click "Deploy" button
50 | - Wait for build and deployment to complete
51 | - Your MCP server will be available at a Smithery URL
52 |
53 | ### Step 3: Test Your Deployment
54 |
55 | 1. **Tool Playground**: Use Smithery's built-in playground to test your tools
56 | 2. **Configuration**: Test with different n8n host and API key configurations
57 | 3. **Integration**: Connect to your hosted MCP server from AI agents
58 |
59 | ## 🔧 Configuration Schema
60 |
61 | Your MCP server accepts the following configuration:
62 |
63 | ```yaml
64 | configSchema:
65 | type: "object"
66 | properties:
67 | n8nHost:
68 | type: "string"
69 | description: "n8n instance URL (e.g., http://localhost:5678)"
70 | default: "http://localhost:5678"
71 | n8nApiKey:
72 | type: "string"
73 | description: "n8n API key for authentication"
74 | required: ["n8nHost", "n8nApiKey"]
75 | ```
76 |
77 | ## 🛠️ Available Tools
78 |
79 | Once deployed, your MCP server provides these tools:
80 |
81 | ### Workflow Management
82 | - `list_workflows` - List all workflows from n8n instance
83 | - `create_workflow` - Create a new workflow in n8n
84 | - `get_workflow` - Get a workflow by ID
85 | - `update_workflow` - Update an existing workflow by ID
86 | - `delete_workflow` - Delete a workflow by ID
87 |
88 | ### Workflow Control
89 | - `execute_workflow` - Execute a workflow by ID
90 | - `activate_workflow` - Activate a workflow by ID
91 | - `deactivate_workflow` - Deactivate a workflow by ID
92 |
93 | ## 🔗 Usage Examples
94 |
95 | ### Connect from Claude Desktop
96 |
97 | Add to your Claude Desktop MCP configuration:
98 |
99 | ```json
100 | {
101 | "mcpServers": {
102 | "n8n-workflow-builder": {
103 | "command": "smithery",
104 | "args": ["run", "@makafeli/n8n-workflow-builder"],
105 | "env": {
106 | "N8N_HOST": "http://your-n8n-instance:5678",
107 | "N8N_API_KEY": "your-api-key"
108 | }
109 | }
110 | }
111 | }
112 | ```
113 |
114 | ### Connect via Smithery API
115 |
116 | ```bash
117 | curl -X POST https://api.smithery.ai/v1/servers/@makafeli/n8n-workflow-builder/tools/list_workflows \
118 | -H "Authorization: Bearer YOUR_SMITHERY_API_KEY" \
119 | -H "Content-Type: application/json" \
120 | -d '{
121 | "config": {
122 | "n8nHost": "http://your-n8n-instance:5678",
123 | "n8nApiKey": "your-api-key"
124 | }
125 | }'
126 | ```
127 |
128 | ## 🐛 Troubleshooting
129 |
130 | ### Common Issues
131 |
132 | 1. **Build Failures**:
133 | - Check that `smithery.yaml` is properly formatted
134 | - Ensure `src/index.ts` exports the required function
135 | - Verify TypeScript compilation succeeds locally
136 |
137 | 2. **Configuration Errors**:
138 | - Validate your configuration schema matches the expected format
139 | - Test configuration values with your n8n instance
140 |
141 | 3. **Tool Execution Errors**:
142 | - Verify n8n API key has proper permissions
143 | - Check n8n instance is accessible from Smithery's servers
144 | - Review tool parameter validation

92 | - Enter repository URL to test preview
93 |
94 | ### Twitter/X:
95 | - Use [Twitter Card Validator](https://cards-dev.twitter.com/validator)
96 | - Test with repository URL
97 |
98 | ### LinkedIn:
99 | - Use [LinkedIn Post Inspector](https://www.linkedin.com/post-inspector/)
100 | - Validate social preview appearance
101 |
102 | ### General Testing:
103 | - [Social Share Preview](https://socialsharepreview.com/)
104 | - [Meta Tags](https://metatags.io/)
105 | - [Open Graph Check](https://opengraphcheck.com/)
106 |
107 | ## Best Practices
108 |
109 | 1. **Image Quality**: Use high-resolution images (minimum 1200px width)
110 | 2. **Text Readability**: Ensure text is readable at small sizes
111 | 3. **Brand Consistency**: Use consistent colors and fonts
112 | 4. **Mobile Optimization**: Test on mobile social apps
113 | 5. **Regular Updates**: Update images when major features are added
114 | 6. **A/B Testing**: Test different preview styles for engagement
115 |
116 | ## Maintenance
117 |
118 | - Update social preview images when major releases occur
119 | - Refresh meta descriptions to reflect new features
120 | - Monitor social sharing analytics
121 | - Update preview images for seasonal campaigns or major announcements
122 |
