# PROXPCProtocol

```
protocol PROXPCProtocol : FxXPCProtocol
```

## Overview

\abstract The protocol used by PluginManager plug-ins that also handle dynamic registration.
\discussion The plug-in should never directly use this protocol. It’s called by the host
application only. Plug-ins should, however, put this protocol name as the
value for the Protocl key in the PluginKit section of their Info.plist file.
