# using-n8n-mcp-skills

Router skill for building n8n workflows through the n8n-mcp server: it sends each task to the specialist skill that owns the rules, and sets the ones that keep flows alive in production.

## What it does

This is a router, not a manual. It picks the specialist skill from the n8n-mcp-skills pack that covers what you are about to do, and it wants that skill loaded before you touch anything: a node edit, an expression inside `{{ }}`, a Code node, a flow design. Three rules come with no exceptions. Invoke the matching skill before any n8n action. Run `validate_workflow` before activating, then call `n8n_get_workflow` after every create or update and read the `connections` object yourself. Keep tokens and passwords in n8n's credential system, never in a text field.

Why bother? Tool names, parameter shapes and node `typeVersion`s drift between releases. The skill says to trust the live tool over remembered syntax, so when `get_node` disagrees with a skill, the tool wins and the drift is worth flagging. It also warns that passing validation only means the JSON is well-formed: a Filter with a broken condition drops every item and still reports success, and a JS error inside an expression resolves to `null`.

None of it fires without the n8n-mcp MCP server. The `PreToolUse` hooks that nudge the agent exist only in the Claude Code plugin install. Everywhere else, from Cursor to Codex, Copilot, Gemini CLI and OpenCode, nothing reminds you, so the rules are on you.

## Requirements
- Works with: n8n

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add czlonkowski/n8n-skills --skill using-n8n-mcp-skills -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/using-n8n-mcp-skills/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/using-n8n-mcp-skills/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add czlonkowski/n8n-skills --skill using-n8n-mcp-skills -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/using-n8n-mcp-skills/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add czlonkowski/n8n-skills --skill using-n8n-mcp-skills -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/using-n8n-mcp-skills/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install czlonkowski/n8n-skills using-n8n-mcp-skills
```

2. **Manually: put the files in place**
- File: `.github/skills/using-n8n-mcp-skills/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add czlonkowski/n8n-skills --skill using-n8n-mcp-skills -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/czlonkowski/n8n-skills --path skills/using-n8n-mcp-skills
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/using-n8n-mcp-skills/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add czlonkowski/n8n-skills --skill using-n8n-mcp-skills -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/czlonkowski/n8n-skills/tree/HEAD/skills/using-n8n-mcp-skills/SKILL.md

## When to use it
- build a workflow from nodes without leaning on the model's memory
- check the `connections` object after every create or update
- move a token out of a Set node and into n8n credentials
- find the right specialist skill for an expression, a Code node or a broken flow
- tell a workflow that validates apart from one that actually works

## Example prompts
- Build an n8n workflow: webhook in, then a filter, then a new row in the table
- The Merge node drops the third source, sort it out
- Check this workflow before I activate it: connections and output values

name: using-n8n-mcp-skills
description: "Use when building, editing, validating, testing, or debugging an n8n workflow through the n8n-mcp MCP server — designing a flow, configuring a node, writing an expression or Code node, wiring credentials, or fixing one that misbehaves. The entry-point skill for the n8n-mcp-skills pack: it routes you to the right specialist skill, gives working knowledge of every n8n-mcp tool from turn one, and states the rules that keep workflows from breaking in production. Always consult it first on any n8n, workflow, node, or automation task — even a quick one-off, and even when the user names no skill — because n8n's surface drifts between versions and the specialist skills prevent silent failures."

# Using the n8n-mcp Skills

This is a **router**, not a reference. It tells you which skill owns the rules for what
you're about to do. The skill bodies hold the actual guidance — invoke them with the
Skill tool. When in doubt, load more skills rather than fewer.

The community **n8n-mcp** server and n8n itself move faster than any model's training
cutoff. Tool names, parameters, node `typeVersion`s, and default behaviors drift between
releases. When you spot drift — a tool a skill names doesn't exist, a parameter shape
doesn't match what `get_node` returns, behavior differs from what a skill describes —
trust the **live tool**, tell the user, and suggest updating the pack and the instance.

## Non-negotiables

Three rules with no exceptions. Each one prevents a class of workflow that looks correct
but breaks in production.

1. **Invoke the relevant skill before any n8n action** — not just before MCP calls.
   Before writing an expression, configuring a node, designing a workflow, wiring a
   connection, or writing Code, invoke the matching skill. PreToolUse hooks remind you on
   the highest-impact tool calls, but they exist **only in the Claude Code plugin
   install**. Everywhere else — Claude.ai skill uploads, and any client that loads this
   pack as an Agent Plugin (Codex, Cursor, Copilot and the rest) — nothing nudges you and
   it's on you. Assume you are un-hooked unless you have seen a
   hook fire this session.
```
