n8n Workflow Automation Repository

A repository of n8n workflow automations built with AI assistance using Claude Code and n8n-mcp.

Overview

This project serves as:

• A workflow library - Reusable n8n automation workflows stored as JSON
• An AI-assisted development environment - Using Claude Code with MCP servers to design, build, and deploy workflows
• A version-controlled backup - All workflows tracked in git for history and collaboration

Workflows

Workflow	Description	Status
Notion-Todoist Bidirectional Sync	Syncs tasks between Notion and Todoist with status mapping and deduplication	In Development

Setup

Prerequisites

• Claude Code CLI installed
• n8n instance (self-hosted or cloud)
• API credentials for services you want to automate

Getting Started

1. Clone the repository

   git clone https://github.com/robbybarnes/n8n.git
   cd n8n

2. Configure MCP servers

   Create .mcp.json with your credentials:

   {
     "mcpServers": {
       "n8n-mcp": {
         "type": "stdio",
         "command": "npx",
         "args": ["-y", "n8n-mcp"],
         "env": {
           "N8N_API_URL": "https://your-n8n-instance.com/",
           "N8N_API_KEY": "your-api-key"
         }
       },
       "notion": {
         "type": "stdio",
         "command": "npx",
         "args": ["-y", "@notionhq/notion-mcp-server"],
         "env": {
           "NOTION_TOKEN": "your-notion-token"
         }
       }
     }
   }

3. Start Claude Code

   MCP servers will automatically connect.

Using Workflows

Import a Workflow

1. Copy the workflow JSON file content
2. In n8n, go to Workflows > Import from File
3. Paste or upload the JSON
4. Configure credentials for each node
5. Test with the Manual Trigger before activating

Deploy via API

With n8n-mcp configured, Claude can deploy workflows directly:

Deploy notion-todoist-bidirectional-sync.json to my n8n instance

Creating New Workflows

Ask Claude to help build automations:

Create a workflow that:
- Triggers when a new row is added to Google Sheets
- Sends a Slack notification to #alerts channel
- Logs the event to a database

Claude will:

1. Search for relevant templates
2. Configure nodes with proper parameters
3. Validate the workflow
4. Save as JSON and optionally deploy

Workflow Documentation

Each workflow JSON includes embedded documentation via sticky notes. Key information:

• Purpose and use case
• Required credentials
• Configuration steps
• Status/field mappings

Contributing

1. Create workflows using Claude Code in this directory
2. Test thoroughly with dry run modes when available
3. Document any required setup in sticky notes
4. Commit the JSON file with a descriptive message

Security Notes

• .mcp.json and .env are gitignored - never commit credentials
• Workflow JSONs may contain database IDs or project IDs - review before sharing publicly
• Use n8n's credential system rather than hardcoding secrets in workflows
