If you don't know the abbreviation, that can also mean you're not the target audience. This is a blog post written for an audience that uses multiple MCP servers, arguing for a different way to use LLMs. If you need the term explained and don't care enough to throw the abbreviation into Google, you're not going to care much about what's being said anyway.

I have no idea what any of the abbreviations in stock market news mean and those stock market people won't know their CLIs from their APIs and LLMs, but that doesn't mean the articles are bad.
