Is there a tool like Swagger for non API methods?

Question

I have a project that consists of Web API methods that are on Swagger and that is fine. The problem is that my login methods went from being in API Controller to classic MVC Controller. I can call my method from a tool like Postman and it works. The thing is that I want the cookie that is created on the login method to be seen in the browser, when I call my API methods. How can I do this? Is there some tool like Swagger for MVC Controller methods?

 

I need this for a purpose of testing the methods without frontend part. So, I would call my method from MVC controller, it would set a cookie in a browser and then I would continue with my Swagger API
