It would be nice to just be able to solve it through instructions to the agent, instead of having to apply all the other things for each application/server/database that I'd like to give it access to
What I imagine is you might instruct an agent to help you set up the restrictions for various systems to reduce the toil. But you should still review what the agent is going to do and make sure nothing stupid is done (like: using regexes to filter out restricted commands).
