LLMs work great with REST so that's always still an option. MCPs have that nice third party plug and play experience but that doesn't mean we all have to build them.
I make tons of little REST APIs for my agents to use and in the AGENTS.md there's just a list of API entry points with descriptions on what they offer. Agents drive them with `curl` and it all works great.
