Yup, I give them a custom entry in ~/.ssh/config like:

``` host claudebox hostname 192.168.122.105 user developer IdentityFile ~/.ssh/id_rsa ```

``` host codexbox hostname 192.168.122.106 user developer IdentityFile ~/.ssh/id_rsa ```

I drop only my public key inside the VM. Then I set up the ~/Projects folder with the code the bot is working on any any authorized samples.

Then in my local on my host clone of the repository, I add another remote like

``` git remote add codexbox ssh://codexbox/home/developer/Projects/hello-world ```

Then git push codexbox.

Then I just SSH in or use the vm gui and interact with the agent there. I like to keep it running in byobu so I can remote in more easily when I am on the laptop out and about.
