I can see where Mario is coming from, but IMO MCP still has a place because it 1) solves authentication+discoverability, 2) doesn't require code execution.

MCP shines when you want to add external functionality to an agent quickly, and in situations where it's not practical to let an agent go wild with code execution and network access.

Feels like we're in the "backlash to the early hype" part of the hype cycle. MCP is one way to give agents access to tools; it's OK that it doesn't work for every possible use case.

Oh, I didn't intend this to come across as MCP being useless. I've written this from the perspective of someone who uses LLMs mostly for coding/computer tasks, where I found MCP to be less than ideal for my use cases.

I actually think MCP can be a multiplier for non-technical users, where it not for some nits like being a bit too technical and the various security footguns many MCP servers hand you.
