I've found it really handy to just have a local Python webserver running on my workstation. Then my bookmarklets can just hit eg http://localhost:8000/cgi-bin/script.py to modify a local file or open up my notes for a certain Jira ticket or whatever else I can think of. There are security considerations with that approach though, since any random site you load can start sending requests to your local webserver.
