Sure, and MCP is just a standardized way of exposing tools. This is where I feel MCP is both overhyped (waaaaaaay too much LinkedIn influencer hot air) but also genuinely quite useful.

I've done stuff very much like the above with just regular tool calls through the various LLM APIs, but there are tons of disparate frameworks for how to harness up a tool, how they execute, how they are discovered, etc. None of it is rocket science.

But the nice thing about having a standard is that it's a well-lit path, but more importantly in the corporate workflow context is that it allows tools to be composed together really easily - often without any coding at all.

An analyst who has zero coding experience can type in a prompt, click "add" on some MCP tools, and stand up a whole workflow in a minute or two.

That's pretty cool.

And yeah, none of it is impossible to implement yourself (nor even very hard!) but standardization has a value in and of itself in terms of lowering barriers to entry.
