ida-rpc was a quick test plugin to see what changed in the 7.0 sdk, subsequently it only supports IDA 7.x as of now updated to IDA 9.0,
it allows for discord rich presence to display information about the current IDA session
To install ida-rpc simply copy ida-rpc64.dll from the latest release to ida_install_location/plugins/
,
to change options within the plugin open the plugins menu and select IDA RPC Edit -> Plugins -> IDA RPC
or use the default hotkey Ctrl-Alt-R
To build this solution you'll need to get a copy of the IDA 9.0 SDK, compile in 64bit Release64 and your done!
