This is very neat! IMO inspecting the queries the agents run on the database is a better approach to understand how the code works, even more than reviewing the code.

I just tried and it works smoothly. For those who doesn't want to plug in the agents to their database directly, I built a similar tool https://dbfor.dev for the exact purpose, it just embeds PGLite and implements PG wire protocol to spin up quick PG databases with a traffic viewer included.

Maybe consider renaming this since pgTAP [0] exists and has nothing to do with this.

Was AI used to build this? It looks a lot like the kind of scratch-an-itch projects I have been grinding out with AI lately, in size, timeline, code, and function. If not, you are a very very productive programmer.

If so, would you mind sharing which model(s) you used and what tooling?

We do something similar in adaptive [1].

What you can also do is add frontend and backend user to the proxy and then agents won't ever get the actual db user and password. You can make it throwaway too as well as just in time if you want.

Traditionally it was database activity monitoring which kind of fell out of fashion, but i think it is going to be back with advent of agents.

Looks really cool, will try it out soon

Can you explain how this is a better option than just enabling the general log for MySQL as needed?

Really been wanting something like this. Thanks!

Nice. I like how you made it an easy to drop in proxy. Will definitely use this when debugging issues!

That's some sick observability, nice.
