n8n skillset for Claude Code to build flawless n8n workflows

What it solves

This project provides a set of specialized instructions (skills) for AI assistants like Claude to help them build production-ready n8n workflows. It addresses common AI failures when automating n8n, such as incorrect expression syntax, inefficient use of MCP tools, validation error loops, and misconfigured nodes.

How it works

It consists of 14 complementary skills and an enforcement layer. These skills act as expert guides that activate automatically when the AI detects relevant queries. They cover specific domains like JavaScript/Python code nodes, AI agents, binary data handling, and self-hosting deployment.

The enforcement layer uses a router skill and hooks (PreToolUse and PostToolUse) to proactively nudge the AI toward the correct guidance before and after it uses n8n-mcp tools, ensuring the AI doesn't just rely on passive query matching.

Who it’s for

Users of Claude Code, Claude.ai, or other AI assistants who use the n8n-mcp MCP server to programmatically build and manage n8n workflows.

Highlights

  • 14 Specialized Skills: Covers everything from expression syntax and node configuration to complex AI agent design and self-hosting.
  • Coded Patterns: Includes production-tested patterns for JavaScript and Python Code nodes, including critical "gotchas" for webhook data access.
  • Proactive Enforcement: Uses hooks to remind the AI of best practices before high-impact tool calls.
  • Deployment Guidance: Includes a dedicated skill for deploying self-hosted n8n on Linux VMs using Docker Compose and Caddy.
  • Broad Support: Grounded in data from over 500 n8n nodes and 2,600+ workflow templates.

    czlonkowski/n8n-mcp

    n8n‑MCP is a Model Context Protocol server that exposes the full n8n node catalog (≈3 000 nodes) as an API. AI assistants can search nodes, fetch detailed property schemas, get documentation, pull example configurations, and retrieve ready‑made workflow templates. The service also offers validation tools and, when given n8n credentials, can create, update, test, and manage workflows directly. It’s designed to let LLMs reliably build and deploy n8n automations.

    Masriyan/Claude-Code-CyberSecurity-Skill

    A genuine open‑source project that provides 22 “Claude Code” skill packs turning Anthropic’s Claude‑Code assistant into a cybersecurity co‑pilot. Each skill is a markdown file with triggers, methodology, templates and optional Python scripts, covering everything from OSINT and vulnerability scanning to AI‑LLM security and purple‑team emulation. Install by copying the `skills/` folders into `~/.claude/skills/` (or a project‑local `.claude/skills/`). Claude then auto‑activates the appropriate skill during conversation, runs helper scripts, and returns ready‑to‑use reports, rules, or commands. MIT‑licensed, with safety gates for offensive actions.
