Pushing to Beanstalk fails with sourcetree but not with mac terminal

Question

I can't seen to push any of my beanstalk repos using sourcetree. The same push works fine with terminal (git push Beanstalk master). Here is the error that sourcetree returns:

git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree push -v --tags Beanstalk refs/heads/master:refs/heads/master
Pushing to git@mdeany.git.beanstalkapp.com:/mdeany/tdc-welcome-email.git
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
Completed with errors, see above

Notice how is says, "Completed with errors". This is untrue. The push is not successful. My public key seems to be still there.

Help ????

That's something that changed in the OS since Sierra. You can read more on how to get it work in Apple's Technical Note - https://developer.apple.com/library/content/technotes/tn2449/_index.html

Ah ok. I think I am supposed to add the private key. This works:

ssh-add ~/.ssh/id_rsa

I get the return:

Identity added: /Users/pm-imac-home/.ssh/id_rsa (/Users/pm-imac-home/.ssh/id_rsa)

But the question now is: Why do I continue to have to add the key to ssh-agent every time I restart my computer?

Also push is still working from terminal:

git push origin master

I am asked for my passphrase. and here it accepted.
