It building on top of them, because MCP did address some issues (which arguably could've been solved better with clis to begin with - like adding proper help texts to each command)... it just also introduced new ones, too.
Some of which still won't be solved via switching back to CLI.
The obvious one being authentication and privileges.
By default, I want the LLM to be able to have full read only access. This is straightforward to solve with an MCP because the tools have specific names.
With CLI it's not as straightforward, because it'll start piping etc and the same CLI is often used both for write and read access.
All solvable issues, but while I suspect CLIs are going to get a lot more traction over the next few months, it's still not the thing we'll settle on- unless the privileges situation can be solved without making me greenlight commands every 2 seconds (or ignoring their tendency to occasionally go batshit insane and randomly wipe things out while running in yolo mode)
It turns out everyone is having the same idea.
