n8n MCP Server Trigger

The MCP Server Trigger node turns an n8n workflow into an MCP server over SSE or Streamable HTTP, exposing attached tool nodes and sub-workflows to any MCP client with optional bearer or header auth.

What it does

Expose n8n tool nodes and workflows as MCP tools
Separate test and production URLs with custom paths
Bearer or header authentication
Works with n8n Cloud and self-hosted instances

Best for

Agencies that already automate Shopify, Klaviyo or ad reporting in n8n and want to hand those flows to an AI agent.

Watch out for

No stdio support, queue mode needs a dedicated webhook replica and claude.ai prompts for sign-in even when auth is set to None.
