Ghidra is great, and I like scripting as much of my RE as possible. But Ghidra's Python scripting is based on Jython, which isn't in a great state these days. Installing new packages is a hassle, if they can even run in a Jython environment, and it's only going to get worse as Python 2 slowly gets turned off.
So Ghidra Bridge is an effort to sidestep that problem - instead of being stuck in Jython, set up an RPC proxy for Python objects, so we can call into Ghidra/Jython-land to get the data we need, then bring it back to a more up-to-date Python with all the packages you need to do your work.
The aim is to be as transparent as possible, so once you're set up, you shouldn't need to know if an object is local or from the remote Ghidra - the bridge should seamlessly handle getting/setting/calling against it.
