There was a comment about just using AGENTS.md instead that got deleted, so I'll answer it anyway:

Natural language markdown instructions are prone to hallucinations or picking the wrong flags, whereas MCP provides a rigid, typed schema with zero guessing. I guess it has to be experienced to be believed, but the speed with which agents navigate project scripts and database queries with the right MCP tools exposed is insane.
