n8n Workflow Skills

作者 haunchen · haunchen/n8n-skills

Agent skill suite that teaches Claude how to read, author, and debug n8n workflows.

n8n's workflow JSON is gnarly. This skill suite — read, validate, scaffold, debug — teaches Claude to produce n8n workflows that actually import and run, including credentials wiring, node placement, and expression syntax.

~/Library/Application Support/Claude/claude_desktop_config.json  · Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "n8n-skills": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/haunchen/n8n-skills",
        "~/.claude/skills/n8n-skills"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config を開く。保存後、アプリを再起動。

~/.cursor/mcp.json · .cursor/mcp.json
{
  "mcpServers": {
    "n8n-skills": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/haunchen/n8n-skills",
        "~/.claude/skills/n8n-skills"
      ],
      "_inferred": true
    }
  }
}

Cursor は Claude Desktop と同じ mcpServers スキーマを使用。プロジェクト設定はグローバルより優先。

VS Code → Cline → MCP Servers → Edit
{
  "mcpServers": {
    "n8n-skills": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/haunchen/n8n-skills",
        "~/.claude/skills/n8n-skills"
      ],
      "_inferred": true
    }
  }
}

Cline サイドバーの MCP Servers アイコンをクリックし、"Edit Configuration" を選択。

~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "n8n-skills": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/haunchen/n8n-skills",
        "~/.claude/skills/n8n-skills"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop と同じ形式。Windsurf を再起動して反映。

~/.continue/config.json
{
  "mcpServers": [
    {
      "name": "n8n-skills",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/haunchen/n8n-skills",
        "~/.claude/skills/n8n-skills"
      ]
    }
  ]
}

Continue はマップではなくサーバーオブジェクトの配列を使用。

~/.config/zed/settings.json
{
  "context_servers": {
    "n8n-skills": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/haunchen/n8n-skills",
          "~/.claude/skills/n8n-skills"
        ]
      }
    }
  }
}

context_servers に追加。保存時に Zed がホットリロード。

claude mcp add n8n-skills -- git clone https://github.com/haunchen/n8n-skills ~/.claude/skills/n8n-skills

ワンライナー。claude mcp list で確認、claude mcp remove で削除。

ユースケース

実用的な使い方: n8n Workflow Skills

Generate a working n8n workflow from a natural-language description

👤 n8n users ⏱ ~15 min intermediate

使うタイミング: You want a starting workflow that imports without 'unknown node' errors.

前提条件
  • Server/skill installed and authenticated — See repo README
フロー
  1. Describe
    Using the n8n skill, build a workflow: webhook in → OpenAI summarize → Slack post to #alerts.✓ コピーしました
    → Valid workflow.json
  2. Import + dry-run
    Validate against the n8n schema and tell me what credentials I need to create.✓ コピーしました
    → Validation pass + credentials list

結果: A real, importable workflow — not a JSON-shaped hallucination.

注意点
  • n8n versions ship breaking schema changes. Pin the skill to your n8n major version (the SKILL.md notes which version it targets). — n8n versions ship breaking schema changes. Pin the skill to your n8n major version (the SKILL.md notes which version it targets).

トラブルシューティング

よくあるエラーと対処法

import says 'unknown node type'

Skill targets a specific n8n version. Check SKILL.md frontmatter; upgrade or downgrade your n8n.

確認: n8n version matches
expression parse error

Use the skill's expression validator before saving the workflow.

確認: Validator returns ok
