OpenAPI Tool Node for AI Workflows

n8n’s MCP Tool Node is a powerful feature, and I believe we can further expand its tool integration capabilities. Inspired by Open WebUI’s approach, I propose adding an OpenAPI Tool Node that would:

  • Connect to any OpenAPI-compliant APIs (local or cloud-based).
  • Auto-generate tool descriptions, parameters, and schemas directly from OpenAPI specifications.

This implementation would follow a similar approach to the MCP Tool Node but extend support to thousands of OpenAPI-compatible services.

Glad I have come across this as I’ve just been trying to do this all weekend and thought I was missing something. Being able to use MCPO or OpenAPI API’s with N8N would make it so much easier.
