mcp-n8n

n8n MCP — query your own n8n instance (BYO).

Part of Pipeworx — an MCP gateway connecting AI agents to 1743+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

ToolDescription
n8n_list_workflowsList workflows in YOUR n8n instance, with an active/inactive breakdown. Answers "how many active workflows do we have", "list our n8n workflows", "which workflows are turned on". Each workflow: id, name, active (on/off), createdAt, updatedAt, tags. Set active_only:true to list just the live ones. Requires your instance_url + n8n API key (_apiKey).
n8n_get_workflowGet one workflow's detail by id from your n8n instance — name, active state, node list (which integrations it uses), tags, timestamps. Get the id from n8n_list_workflows. Requires your instance_url + n8n API key (_apiKey).
n8n_list_executionsList recent workflow executions (runs) in your n8n instance — for "did our workflows run", "show recent failures", "execution history". Each: id, workflowId, status (success/error/waiting), mode, startedAt, stoppedAt. Filter by status and/or workflow_id. Requires your instance_url + n8n API key (_apiKey).

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "n8n": {
      "url": "https://gateway.pipeworx.io/n8n/mcp"
    }
  }
}
What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/n8n/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1743+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

This pack takes your own API key (_apiKey) — we don't front one for it, so there's no curl here that would run without it. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/n8n_list_workflows. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "n8n": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-n8n"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-n8n

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about N8n data" })

The gateway picks the right tool and fills the arguments automatically.

Questions fréquentes

Qu'est-ce que N8n ?

n8n MCP — query your own n8n instance (BYO).

Comment installer N8n ?

Il fonctionne comme serveur distant. Dans Claude Code : claude mcp add --transport http n8n 'https://gateway.pipeworx.io/n8n/mcp'. Pour les autres clients, collez la configuration JSON de cette page dans leurs réglages MCP.

Faut-il une clé API pour N8n ?

Son entrée au registre n'indique aucune clé ni secret obligatoire. Certaines fonctions peuvent tout de même demander un compte auprès du service auquel il se connecte.

N8n est-il open source ?

Oui. Son code est sur GitHub sous licence MIT.

Qui maintient N8n ?

Il est publié par pipeworx-io. AI.tn le référence sans le maintenir ni le recommander.

Issu du registre MCP officiel. Être listé n'est pas une recommandation : vérifiez le code et les permissions d'un serveur avant de lui donner accès à vos données.
