Hi Michael,
If you are automatically injecting the JavaScript agent to your user's browsers from a particular process then yes the agent needs to be installed on the host that process is running on. In most cases, I have seen the Automatic JavaScript injection being setup on the frontend process like a webserver. So in your case unless you are doing the Automatic JavaScript injection via another process on a different host, you will need to install the agent on the frontend host. See more on JavaScript injection below
