n8n MCP server

n8n runs the automations of many teams, on n8n Cloud or on their own server. Through Flowplane an AI assistant can search the workflows you made available in MCP and look at them, and run one, which waits for your approval by default. On n8n 2.13 and later it can also build or edit workflows, which also waits for your approval by default.

What it can do

What your assistant can do in n8n

Flowplane passes n8n’s own MCP server through, so the tools are the ones n8n offers when you connect. By default reads are allowed and anything that changes something waits for the person’s approval; your workspace’s rules decide.

Reads allowed

Looking things up runs straight away, within what the account you connected may see.

Changes asks first

Creating, changing or deleting waits for your approval in the browser, unless your workspace’s rules say otherwise.

How it connects

Sign-in

Sign in with your n8n account (OAuth), the preferred way, so the assistant acts as you. If your n8n offers no sign-in for assistants, you can choose to paste an access token from n8n (Settings, Instance-level MCP) instead. A workflow runs with the rights of the n8n user who signed in or made the token. Flowplane keeps the login sealed; the assistant never sees it.

In Flowplane: In the Flowplane console, add n8n, type the address you open n8n at, and sign in with n8n. For an n8n inside your network, choose a tunnel and use an access token.

MCP

n8n and MCP

Yes: n8n has its own MCP server built into every instance (instance-level MCP), which an owner or administrator turns on. Flowplane connects to your n8n’s own server and passes its tools through, so reads are allowed and anything that runs or changes a workflow waits for your approval by default.

FAQ

Questions

What do I need to turn on in n8n?
An owner or administrator opens Settings, Instance-level MCP and turns it on. Then, for each workflow to share, turn on “Available in MCP”. The assistant sees only those workflows.
Can the assistant run any workflow without asking?
Not by default. Searching and reading workflows are allowed; running, building or editing a workflow waits for your approval by default. n8n’s tools are treated as changes unless they say they only read. Use an n8n account that can see only what should be shared.
Which AI assistants can use n8n through Flowplane?
Claude, Claude Code, ChatGPT, Cursor, Codex, GitHub Copilot and Mistral Le Chat, and any other client that supports remote MCP servers with sign-in. They all reach n8n through the same Flowplane address.
What does it cost?
Free for one person, with up to three apps and five assistants. Personal Pro is €9 a month including VAT; companies start at €99 a month for ten active users. Prices are indicative; see the pricing page.

Flowplane is not affiliated with or endorsed by n8n’s maker; the name and logo only identify the app. Pricing
