0:00.0	Welcome to Syntax today. We have a show on Chrome's new DevTools MCP server. This is actually
0:08.2	kind of nifty as a way to both help you debug as well as figure out what's going on your website,
0:15.5	programmatically control, figure out network issues that are going on. There's a whole bunch of
0:20.4	use cases. So we're going to talk about that today. My name is West Boss. I'm a developer from Canada with me as always. Is Mr. Scott. Talinsky, how you doing, Scott? Oh, man, I'm doing much better. Last week, at the start of the Ricky episode, when we recorded recorded within like the first couple of moments.
0:37.7	And it might have been before we hit record.
0:39.8	I chip my dang tooth on a glass straw.
0:43.4	So the entire episode, I'm just sitting there like trying to like have a conversation
0:47.5	and my mouth is just like killing me.
0:51.4	So was it like a big, big chip?
0:54.2	It's a, no, you can probably kind of see it.
0:56.3	It's this tooth right here.
0:57.2	It just kind of chips in, kind of took out a little bit of the bottom.
1:01.0	So no good.
1:02.3	I haven't gotten anything done about it because it's gotten kind of less sensitive, but I'll get it looked at, I suppose.
1:09.7	Awesome.
1:10.6	Well, not awesome. Awesome. Awesome. not awesome. All right. Let's talk about the MCP server, though. Before we get started, two things. Meetup and Spooky Stories Submission. We need you for both. October 27, we are going to be doing a meetup in San Francisco at Bear Bottle Beer Garden in Salesforce Park. We're in town for Get Up Universe. You don't have to actually be a meetup in San Francisco at Bear Bottle Beer Garden in Salesforce Park. We're in town for
1:30.3	Get Up Universe. You don't have to actually be going to Get Up Universe to go to this. It's open to
1:34.0	anybody. We're going to have a bunch of drinks, a bunch of swag, really good time. So if you're
1:38.3	anywhere in the California area, or somewhere in California or anywhere you want to fly down. Come on out. October 27th.
1:46.9	It's going to be a hoot. Go to syntax.fm forward slash meetup and you can grab a ticket.
1:52.0	They are free, but you do have to reserve one because space is limited.
1:55.8	Second, Halloween's coming up. We need your spooky stories. This is an episode we do every single year
