Once connected, your assistant can list the automations already sitting in your n8n account, create new ones, update or switch them off, and trigger a run on demand. It works with Claude Desktop, ChatGPT, Cursor, VS Code and other assistants that speak MCP, and there is a hosted version on Smithery if you would rather not install anything at all. You will need your own n8n account plus an access key copied from its settings.

n8n-workflow-builder FAQ

Is this project still maintained?

Yes, though not weekly. The last change landed in March 2026, and the package is still published and installable.

Do I need an n8n account already?

Yes. This talks to an n8n instance you already run, either self-hosted or on n8n's cloud, and you supply an access key from its settings.

Which apps does it work in?

Claude Desktop, ChatGPT, Cursor, VS Code, Cline and other assistants that support MCP.

Can I use this to build a whole automation from a description?

Yes. You describe what should happen and the assistant creates the workflow in your account, which you can then review in n8n before switching it on.

How hard is setup?

You paste a short snippet into your assistant's settings and add your n8n address and key. The hosted option on Smithery skips even that.

Can it break my existing automations?

It can change, deactivate and delete workflows, so give it a key with only the permissions you are comfortable handing over.
