(Node-RED project lead here) There are a few nodes for dealing with swagger in Node-RED - either generating Swagger doc for your HTTP end points, or on the client side to make it easy to interact with a Swagger documented API.

For example: https://flows.nodered.org/node/openapi-red

If you're looking for something that can take a Swagger/OpenAPI doc and generate a stubbed-out set of flows - that would be a neat idea. Sounds like a cool project to create as a pluing.
