If you test backend services, you know the
ritual. A new service shows up, you need to poke its endpoints, so you open Postman and start building a collection request by request. Method, URL, headers, auth, request body, fix the folder structure, name everything so future-you can read it. On a service with a few dozen endpoints, that's an hour or two gone before you send a single request.
I haven't done that in months.
Now I hand the API definition to Claude, and it builds the whole collection through the Postman MCP server in a few seconds - laid out as a step-by-step runbook, with values already filled in. I just hit Send and read the responses. This post is how I set it up and how I actually use it day to day.
The usual way, and why it's a waste
