Welcome to Syntax. Today, we had an episode on building MCP servers. We talked about MCP, I don't know, maybe a couple months ago. And so much has changed since that episode that I thought we need to do a brand new episode on explaining what it is, explaining all the updates to it and kind of diving into all of the different pieces and tools

and helpful things around it.

MCP is the model context protocol.

It's for exposing tools to AI.

We'll talk a little bit more about that, but it's going to be a great episode.

You're certainly not going to want to miss this one.

What's up, Scott?

Oh, hey, man.

I'm sick. All this stuff. There's, there's been somebody jackhammering, I'm going to say this. Somebody's jackhammering a patio

for like two straight days now. And this is finally the first little window where there's been

some silence. I mean, they were

jackhammering at like 6 p.m. We were going to eat outside and it was still going on. I don't

understand how you could spend that much time jackhammering a patio. That's an unreasonable time to

jackhammer. Yeah. Yeah, you can't do that. You can't, when people are trying to eat dinner and

you're jackhammering. So yeah, not a fan of that. You can't. People are trying to eat dinner and you're jackhammering.

So, yeah, not a fan of that. And, yeah, so besides that, I've just been, like, banging my head against some code stuff. And I'm sure the jack hammering has not been, like, helping my brain function today. Yeah. So that's where I'm at. Yeah, one of those days, right? Well, I'm going to fill you with MCP nuggets. And I feel like you'll be, you'll be back to your bright self by the end of this.

Love that. Yes. So, all right, let's get in on into it. So MCP, it's a standard for being able to surface tools to AI.

So whether you are using like an IDE editor like VS code or cursor,

or whether you're using a chat application like Claude Desktop,

or whether you are building your own thing with AI libraries, like the OpenAI TypeScript

Library. All of those things have the ability to surface additional tools to it via something

called MCP. And I'll give you an example of where I ran into it recently. I built my second MCP server a couple days ago, so I'm feeling fresh on that. I used a lot of the new features that have come out since we did the first episode on it. So the application that I was building was sort of like this little scratch pad that will
