This repository contains a GitHub Actions workflow to extract the protocol buffer definitions (.proto) from the Magic: The Gathering Arena (MTGA) setup and commit it.
As of now, the protobuf definitions are contained in the file Wizards.MDN.GreProtobuf.Unity.dll. This file is part of the MTGA setup. This repository uses MsiExtractor to extract it from the MTGA MSI setup.
The current version information used by the MTGA update mechanism can be found at
