Leaving this here as this was a godsend when I needed to install plugins that weren’t available for the exact engine version I was using:
Needs your credentials to see what you own obviously… so, be careful who you trust. I can’t guarantee the safety of using it and I didn’t validate that the login page it presents is 100% legitimate… But the tool works. Maybe set up 2FA first at least?
(edit) this command allows you to go through your native browser instead
legendary auth --disable-webview
relevant commands for getting plugins:
legendary list --include-ue -T
find the line for your desired plugin, then use the “App Name” field
legendary install <App name>
(remove the <>, of course)
For filtering you can do this in powershell:
legendary list --include-ue -T | Select-String "Version: 5.1"
