Or... it's a tool to expose APIs to LLMs.

functions that an LLM can use in its reasoning are called "tools", so the prior is probably more correct in the sense that an API can be used to provide the LLM tools

I just thought the inversion was fun. A lot of MCPs are basically wrappers around APIs, hence the comment. But certainly not all of them.
