Using SCP command to download files from Linux server to client server

I'm creating files on a Linux server that I'm logged into and I'm adding the ability for the user to download these files from the Linux server on to the connecting computer. I'm writing a scrip and using the scp command to download these files: 

scp data.txt user@usraddress:/home/usr

However, I don't want to specify "user@usraddress:/home/usr" to be just my computer. I want whoever is logged onto the linux server to be able do download these files. Is there a way to get the address of the connecting computer? How would I do this?

Forgive me if this seems elementary, I'm very new to scripting.

When you open a remote session in a GNU/Linux machine, the ssh server sets the environment variable SSH_CONNECTION with some connection information. You can use this variable and the $USER variable to fill that parameters:

scp data.txt $USER@${SSH_CONNECTION%% *}:/home/$USER

Note that as far as I know you couldn't assume the client home directory is at /home. As said by chepner, you could omit the destination directory to use the default location, the home directory.

scp data.txt $USER@${SSH_CONNECTION%% *}:
