|Seven complementary Claude Code skills for building production-ready n8n workflows using the n8n-mcp MCP server, covering expression syntax, workflow patterns, and validation error handling.
Overview
n8n MCP Skills is a plugin providing 7 complementary Claude Code skills that teach AI assistants how to build production-ready n8n workflows using the n8n-mcp MCP server. It solves common challenges like incorrect MCP tool usage, validation error loops, and workflow pattern confusion by providing structured guidance for every aspect of n8n workflow development.
Key Features
- n8n Expression Syntax - Teaches correct n8n expression syntax including core variables ($json, $node, $now, $env), critical gotchas like webhook data under
$json.body, and common mistakes with fixes - MCP Tools Expert - Highest priority skill providing a tool selection guide, nodeType format differences, validation profiles, smart parameters, and correct MCP tool usage patterns
- Workflow Patterns - 5 proven architectural patterns (webhook processing, HTTP API, database, AI, scheduled) drawn from 2,653+ n8n templates with connection best practices
- Validation Expert - Interprets validation errors, guides fixing, handles false positives, and breaks validation loop cycles that commonly trap developers
- Operation-Aware Node Configuration - Teaches correct node configuration based on the specific operation being performed, avoiding misconfiguration issues
Who is this for?
This plugin is designed for developers and automation engineers who build n8n workflows programmatically using the n8n-mcp MCP server and Claude Code. It is especially valuable for those who have struggled with validation errors, incorrect MCP tool usage, or figuring out which workflow patterns to apply for their automation use cases.
