MCP.Pizza Chef: salacoste

Describe the automation you want in plain words, such as sending yourself an email whenever a form is filled in, and it gets assembled inside n8n for you. Twenty-four tools ship, more than the seventeen the readme advertises, covering creating and updating workflows, turning them on and off, tags, saved logins, and past runs. You need your own n8n site plus a key copied from its settings. It works in Claude Desktop and Cursor. Kicking off a run on demand is the least reliable part.

AI-Powered Workflow Builder - Build n8n workflows with natural language

🎯 What is This?

n8n Workflow Builder MCP Server transforms workflow automation by enabling you to create and manage n8n workflows through conversational AI. No more manual JSON editing or complex UI navigation—just describe what you need in natural language, and let AI build it for you.

The Problem It Solves

❌ Manual workflow building is time-consuming and error-prone
❌ Complex JSON editing requires deep technical knowledge
❌ Switching between IDE and n8n UI breaks your development flow
❌ Managing multiple n8n environments (dev, staging, prod) is tedious

mcp-n8n-workflow-builder FAQ

Do I need my own n8n before this is any use?

Yes. This drives an n8n site you already run, whether self-hosted or on n8n's paid cloud, and it cannot do anything without one.

Does it need a key?

Yes. You generate a key inside n8n's own settings and paste it in. There is no other sign-in method.

Which apps does it work in?

Claude Desktop and Cursor are documented, and it will work in any app that accepts a standard MCP settings block.

Can I use this to run a workflow right now?

Sometimes. It asks n8n to run the workflow through a route that not every n8n version offers, so on-demand runs can quietly fail even when everything else works.

How hard is it to set up?

Middling. Install one package, then paste a short block into your app's settings file. Handling several n8n sites at once needs one extra small file.

Is it still being worked on?

Yes. The code was last updated in April 2026, and the project keeps a large documentation site alongside it.
