n8n skills Expert Claude Code skills for building flawless n8n workflows using the n8n mcp MCP server Watch the Introduction Video 🎯 What is this? This repository contains 14 complementary Claude Code skills — plus an always on router skill and a hooks enforcement layer — that teach AI assistants how to build production ready n8n workflows using the n8n mcp MCP server, and how to deploy the self hosted n8n that runs them. 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 14 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 architectura
