mitmproxy is an SSL-capable, intercepting HTTP proxy. It provides a console interface that allows traffic flows to be inspected and edited on the fly.
mitmdump is the command-line version of mitmproxy, with the same functionality but without the frills. Think tcpdump for HTTP.
Both tools are fully documentented in the commandline --help flag, and, in the case of mitmproxy, a built-in help page accessible through the ? keyboard shortcut.
