Support This Project
**n8n-mcp** started as a personal tool but now helps tens of thousands of developers automate their workflows efficiently. Maintaining and developing this project competes with my paid work. Your sponsorship helps me dedicate focused time to new features, respond quickly to issues, keep documentation up-to-date, and ensure compatibility with latest n8n releases. **Become a sponsor**

Important Safety Warning
**NEVER edit your production workflows directly with AI!** Always:
- Make a copy of your workflow before using AI tools
- Test in development environment first
- Export backups of important workflows
- Validate changes before deploying to production
AI results can be unpredictable. Protect your work!

Cloudflare Access Authentication
If your n8n instance sits behind Cloudflare Access (Zero Trust), provide your service token so n8n-MCP can authenticate:
- N8N_CF_CLIENT_ID - Cloudflare Access Client ID
- N8N_CF_CLIENT_SECRET - Cloudflare Access Client Secret
When set, these are sent as CF-Access-Client-Id / CF-Access-Client-Secret headers on n8n API requests, version/health probes, and webhook executions. The token is confined to the N8N_API_URL origin — webhook calls to a different host (e.g. a split WEBHOOK_URL origin) do not receive it, to avoid leaking the token.
