YouTube video by Jack Herrington Remix V3's Fatal Flaw

I've changed my mind, what I thought was the coolest part of the Remix V3 proposal I now think is its fatal flaw. And no, I'm not talkin' bout iframes or generators. youtu.be/5SPqO6NR_Bg

YouTube video by Jack Herrington MCP Client Setup in 10 Minutes – Part 2 of DIY MCP Series

Last week we did an MCP Server from scratch. This week we're doing the MCP Client! Nothing teaches you what a protocol can and can't do, and how it works, than building it for yourself! youtu.be/S2x1bsMk19I

If folks just learned what references in JS are, easy, 50% of problems solved.

The one where it's leaning down into and pecking at the, whatever that is, is a fantastic shot. The rest are great as well, but that, going kind of eye to eye with it... chef's kiss.

Three things: 1) Runtime reflection, which only GQL supports and only when it's enabled. 2) The AI can't natively access your APIs without tools. And 3) With those tools it would have to parse your whole API before making requests, and it could get that wrong.

So why not just give it the tools?

YouTube video by Jack Herrington DIY MCP Part 1: MCP Server

MCP is blowing up right now and you need to know how it works. What better way to understand it than to build it from scratch. No libraries. No abstraction layers. Let's start this three part (at least) series by building an MCP server from scratch! youtu.be/nTMSyldeVSw

🔥 Big shifts in web dev this week:

- 🧠 @vscode.dev wants to be the AI editor

I’m excited to hear about it.

YouTube video by Jack Herrington Server Functions Don't Exist (It Matters)

Server functions are super cool, but they aren't a web standard. So what are they? How do they work? What are the pros and cons? And the differences between the Solid, NextJS, Start and Qwik versions? Let's find out! youtu.be/FPJvlhee04E

Actually pretty important. Having had some experience with a morgue I can tell you that... pets get hungry.

Free app idea: "Proof of life" An app for dog/cat/pet sitters to be able to upload images and photos of folks pets doing fun things (or just being, you know, alive.)

It looks like it supports any STDIO server. They'll have to add a web/SSE option later because it looks like MCP is migrating in that direction. But for the moment it's STDIO only.

@raycast.com added MCP support and I'm happy to say that create-tsrouter-app for building @tanstack.com apps works flawlessly with it. Now you can create a TanStack app with just a shortcut and a prompt.
