Get claude to write your n8n automations
This repository helps claude code create n8n workflows. it is free and open source. here is the description from the project.
Let us know i you try it and how you are getting AI to help write your n8n automations
This repository contains 5 complementary Claude Code skills that teach AI assistants how to build production-ready n8n workflows using the n8n-mcp MCP server.
Why These Skills Exist
Building n8n workflows programmatically can be challenging. Common issues include:
- Using MCP tools incorrectly or inefficiently
- Getting stuck in validation error loops
- Not knowing which workflow patterns to use
- Misconfiguring nodes and their dependencies
These skills solve these problems by teaching Claude:
- ✅ Correct n8n expression syntax ({{}} patterns)
- ✅ How to use n8n-mcp tools effectively
- ✅ Proven workflow patterns from real-world usage
- ✅ Validation error interpretation and fixing
- ✅ Operation-aware node configuration
📚 The 7 Skills
1. n8n Expression Syntax
Teaches correct n8n expression syntax and common patterns.
Activates when: Writing expressions, using {{}} syntax, accessing $json/$node variables, troubleshooting expression errors.
Key Features:
- Core variables ($json, $node, $now, $env)
- Critical gotcha: Webhook data is under $json.body
- Common mistakes catalog with fixes
- When NOT to use expressions (Code nodes!)
2. n8n MCP Tools Expert (HIGHEST PRIORITY)
Expert guide for using n8n-mcp MCP tools effectively.
Activates when: Searching for nodes, validating configurations, accessing templates, managing workflows.
Key Features:
- Tool selection guide (which tool for which task)
- nodeType format differences (nodes-base.* vs n8n-nodes-base.*)
- Validation profiles (minimal/runtime/ai-friendly/strict)
- Smart parameters (branch="true" for IF nodes)
- Auto-sanitization system explained
Most Important: Teaches correct MCP tool usage patterns and parameter formats
3. n8n Workflow Patterns
Build workflows using 5 proven architectural patterns.
Activates when: Creating workflows, connecting nodes, designing automation.
Key Features:
- 5 proven patterns (webhook processing, HTTP API, database, AI, scheduled)
- Workflow creation checklist
- Real examples from 2,653+ n8n templates
- Connection best practices
- Pattern selection guide
4. n8n Validation Expert
Interpret validation errors and guide fixing.
Activates when: Validation fails, debugging workflow errors, handling false positives.
Key Features:
- Validation loop workflow
- Real error catalog
- Auto-sanitization behavior explained
- False positives guide
- Profile selection for different stages
5. n8n Node Configuration
Operation-aware node configuration guidance.
Activates when: Configuring nodes, understanding property dependencies, setting up AI workflows.
Key Features:
- Property dependency rules (e.g., sendBody → contentType)
- Operation-specific requirements
- AI connection types (8 types for AI Agent workflows)
- Common configuration patterns
6. n8n Code JavaScript
Write effective JavaScript code in n8n Code nodes.
Activates when: Writing JavaScript in Code nodes, troubleshooting Code node errors, making HTTP requests with $helpers, working with dates.
Key Features:
- Data access patterns ($input.all(), $input.first(), $input.item)
- Critical gotcha: Webhook data under $json.body
- Correct return format: [{json: {...}}]
- Built-in functions ($helpers.httpRequest(), DateTime, $jmespath())
- Top 5 error patterns with solutions (covering 62%+ of failures)
- 10 production-tested patterns
7. n8n Code Python
Write Python code in n8n Code nodes with proper limitations awareness.
Activates when: Writing Python in Code nodes, need to know Python limitations, working with standard library.
Key Features:
- Important: Use JavaScript for 95% of use cases
- Python data access (_input, _json, _node)
- Critical limitation: No external libraries (requests, pandas, numpy)
- Standard library reference (json, datetime, re, etc.)
- Workarounds for missing libraries
- Common Python patterns for n8n
