The bad news is that, unlike VirtualBox or VMWare that allows you to define "Shared Folders" which are directories on your host that are exposed to the guest, Windows 8 Hyper-V does not provide such feature at all.
The good news is that, since there is not such feature provided out of box from Hyper-V at all, there won't be necessary special purposed tools for it, e.g., for mounting
vboxsf file systems. You just going through the official/standard way, accessing your host share folders as network shared folders.
smbclient, the command-line
SMB/CIFS clients for Unix, is the command-line tool to access to your Windows host share folders. Below are two examples that I found. Again, nothing special, access it the same way as you access any other Windows network shared folders.

I'll repost the "Configure a shared folder" section from the second link:
We need to share out a folder in the host to the guest. Guest can mount this on boot. For this tutorial, I’ll assume we are sharing it from a this location
In the VM, edit the
//WinHost/users/username/workspace /home/username/workspace cifs defaults,soft,uid=username,gid=users,file_mode=0777,dir_mode=0777,credentials=/home/username/.cifs-credentials,soft
Also, add a credentials file for the mount to work. Put the following content in there:
That should be it.
More references for GUI based mounting:
If it doesn't work for you at first, try with a Windows based client first to access the host share folders. Again, nothing special, access it the same way as you access any other Windows network shared folders. I.e., some how-tos says that you "must have Created Internal Virtual Switch Via Virtual Switch Manager" to use the host share, that is purely not necessary and it gives you no benefits/advantages at all, since we are just accessing it as a normal Windows network shared folder. To recap, here are the steps:
On your Hyper-V host, create a shared folder and assign Change permission to Everyone.
On the virtual machine running on the host, open the Network and Sharing Center and enable File and Printer Sharing.
On the virtual machine, click Start and type
host_name is the name of your Hyper-V host and
share_name is the name of the share you created.
Press ENTER and an Explorer window will open in the VM showing the contents of the shared folder on the host.
You can now copy files from the VM to the host and vice versa as needed.
