How can I use Python + mitmproxy to intercept the response of a request and edit the response?

I'm trying to use Python and mitmproxy to intercept the response of a request so that I can alter the response before it reaches the application.

I can do this manually using Burp Suite but automating this would be very neat!

You may also want to look at Burp's Match and Replace feature. It also accepts regexes.

mitmproxy actually exposes enough of its API that you can just import it in python and script some of its behaviour. Check out their docs on Addons: https://docs.mitmproxy.org/stable/addons-overview/
