Expose to Rest API

I am using MDocs on my site but we also have several external sites that use links to individual docs in MDocs. This has been fine up until now, but now I need to list a folders on the external site (.net) among other content. I have decided to use the REST API in WordPress to serve content for this.

Is MDocs setup to be exposed to the REST API? If so, what should the call be to? I’ve tried several iterations of wp-json/wp/v2/MDocs etc but I can’t seem to get anything out.
