Flipping the Script on MCP: What I Learned from Matt Carey

From skepticism to fascination: the power of Code Mode

Hey there! I'm Karan, and today I want to talk about something that's been on my mind since I listened to Matt Carey's interview on Changelog. 🤔 I have to admit, I was one of those who thought they knew what MCP was all about, but boy, was I wrong!

The Game-Changer: Code Mode

Okay, real talk — when I first heard about Code Mode, I was skeptical. But after digging in, I get it. Code Mode is not just a feature; it's a paradigm shift in how we think about MCP. With server-side Code Mode, one MCP server can expose all ~2,500 Cloudflare API endpoints in about 1,000 tokens of context. That's mind-boggling! To put it simply, this means that developers can now use MCP to build complex applications with a fraction of the code they would have needed before.

What This Means for Developers

  1. It saves you time — and time is money, friend. With Code Mode, you can focus on writing code that matters, rather than boilerplate code.
  2. It's surprisingly easy to pick up. I know, I know, it sounds too good to be true, but trust me, it's not. The dynamic Worker loader that runs model-written code safely in a V8 isolate is a total game-changer.
  3. Companies are already investing in it. Cloudflare is already using MCP to build complex applications, and they're seeing some amazing results.

The Future of Agents

Matt's own workflow with Claude is really interesting. He's using MCP to build agents that can interact with the world in a more human-like way. And with the Zaggy git wrapper, he's able to keep his agents from force-pushing his repos. It's a clever solution to a real problem. But what really caught my attention was the discussion on memory and how it fits into the future of agents. As agents become more complex, they'll require more memory to function effectively. This is an area that I think will see a lot of innovation in the coming years.

My Take

I have to say, I'm impressed. I was skeptical at first, but after learning more about Code Mode and MCP, I'm convinced that this is the future. It's not just hype; this is a real game-changer. And the fact that Cloudflare is already investing in it is a testament to its potential.

The Potential Use Cases

The potential use cases for Code Mode and MCP are endless. From building complex applications to creating intelligent agents, the possibilities are vast. And with the dynamic Worker loader, developers can focus on writing code that matters, rather than worrying about the underlying infrastructure.

Conclusion

So, what's the takeaway? Code Mode and MCP are not just buzzwords; they're a reality that's changing the way we think about development. It's time to start paying attention and learning more about this technology. Whether you're a seasoned developer or just starting out, Code Mode and MCP are worth exploring. So, start small, start now, and see where it takes you! 🚀
