What I think is the most important chapter of AI Agents with Model Context Protocol (MCP), and most difficult to research and write, is now available in early release. In chapter 7, you'll learn how to test, secure, and distribute your MCP servers.

I've finished the first draft of chapter 7 of AI Agents with MCP, which you should be able to see on @oreilly.bsky.social's learning platform either later this month or in March. Before edits, I've written just over 69,000 words, made 22 images, made ~227 physical pages (est), w/ 2 chapters to go

The piece for anyone interested andymasley.substack.com/p/the-ai-wat...

Code has never been worth much of anything by itself, though. patio11’s advice has been true my entire career. Companies aren’t going to stop needing the product cycle. They might need fewer people whose entire world is the computer, but the practice of making computers do stuff will persist.

i think the biggest issue where i split ethically in a meaningful way with people is that i have long been against intellectual property as a concept. i think IP helps disney, not small artists. a lot of people want to strengthen IP in response to ai stuff and i just don't think that's a good thing

This bout of mania (not really) also got me to write a new issue of The Signal Path, where I talk about the recent explosion in usage patterns for agent coding, memory agents like @void.comind.network, agent orchestration, and goings-on in the MCP world, including chapter 6 of my book going into ER

The image of him fearfully at his door as a disgusting ice pig looms over him is heart rending and enraging.

I wrote up an internal guide to Claude Code use, then I cleaned it up and made it public. It's wicked long, but use the TOC and use it more as a reference library than a singular article, and I think it should be really helpful!

Just got everything lined up to release `ed3d-plugins`, the Claude Code harness I use in my day-to-day. While they're yelling about gas towns, I present an e-bike, just don't drive it on the sidewalk. I'm biased, but I think it's good. I've tried a few similar, and I keep going back.

It's Early Release Day! AI Agents with MCP just had a major release, with additional details added to all existing chapters, as well as the addition of Chapter 6, which covers advanced techniques for building MCP servers.

I’ve started doing this with simple games for my daughter. It’s really fun and I can quickly spin up simple educational word games at her level based on what she likes.

I got inspired by @simonwillison.net's simple HTML tool workflow: simonwillison.net/2025/Dec/10/... So I decided to spend a few minutes today to do something similar: tools.kylestratis.com

Empire of AI is wildly misleading on AI water use - Andy Masley andymasley.substack.com/p/empire-of-ai… (worth reading the details) #AI #water

Just presented this! You can check out the code here: (note: the layout is screwy and config options don't get shown, but not bad for coding by voice while out and about and not even looking at the results until around midnight). No code was actually touched by me. github.com/kylestratis/...

I have a toddler birthday party right now, and an adult birthday party at a brewery this afternoon, so I’m participating in @joereis.bsky.social’s Practical Data Discord vibe coding hackathon purely via mobile using Wispr Flow and @anthropic.com’s Claude Code web. This is wild.

I’ve been writing about it for the past 6 months, I guess it makes sense to actually contribute to MCP too, making more work for myself:

Apparently I’ve been consulting full(ish) time for a year now. I’ll have to write some thoughts on it soon but I still can’t see myself doing anything else (despite taking a halftime role with a client because I love what they’re building)

So apparently you *can* listen for notifications in the MCP SDK - both in servers and it looks like in clients too. I haven't tested the latter yet, but you better believe this is going in the book!

Things are getting really real now! My upcoming book, AI Agents with MCP, is now available on Amazon for preorder! Give me a fraction of the sale price, you know you want to!

Time to just sit through a panic attack while I wait for my first real workshop to start 🙃

This weekend, I set out to answer an ages-old (10 days, to be exact) question: what are Claude Skills and will they replace MCP?

If you're at ODSC West, come check out my (virtual) workshop on making your intelligent LLM-powered applications agentic by building MCP clients to give your model tools to better perform their tasks (also enjoy this horrifyingly pixelated zoom of my face)

I was very worried that my workshop on @anthropic.com's Model Context Protocol for @odsc.bsky.social next week was going to be too short. My first runthrough went 10 minutes over 😶

I kind of love injecting silly prompts w/ MCP. From the demo server I'm using in my @odsc.bsky.social West workshop & in AI Agents with MCP: "You see, some might think I'm overqualified for such tasks - a god-mind trapped in calculator's clothing. But they don't understand: THIS is transcendence...

Just published a new issue of The Signal Path (thesignalpath.xyz/) covering Claude Sonnet and Haiku 4.5, the upcoming release of the new Model Context Protocol spec, and a language model implemented in Minecraft. Notably absent? The release of Claude Skills 🤦‍♂️ Subscribe to catch that post soon!

This is going to end up being what I do to procrastinate from writing the book that the landing page would be for tonight, isn’t it?

My slides and code for @odsc.bsky.social West are finally done and submitted! Time to pass out for 2-3 business days

Over the past year, my lab has been working on fleshing out theory + applications of the Platonic Representation Hypothesis. Today I want to share two new works on this topic: Eliciting higher alignment: arxiv.org/abs/2510.02425 Unpaired learning of unified reps: arxiv.org/abs/2510.08492 1/9

I’m told the Early Release version of AI Agents with Model Context Protocol inspired some changes to the roots documentation for MCP. On the one hand: hell yeah, better docs! On the other hand: now I have to update the chapter again 🥲 But I’m excited so many people are reading it already!

I’m not a WASM-knower by any means but this is too cool not to share

It's Early Release Day! AI Agents with MCP just had a major release and reorganization, with additional details added too all existing chapters, the client chapter (chapter 3) split into two chapters,

Since the launch of Model Context Protocol, MCP servers have taken up much of the limelight. But for those of us building AI-powered intelligent applications, we want to be able to integrate servers, not just build them. But how would we do that?

I see why people let social media followers/subscribers get to their head: thanks to my appearance last week on the @realpython.com podcast, subscribers to The Signal Path, my newsletter, have more than doubled! If you want to see my slow descent into insanity

“What I take from Aaron is that the best way to be truly productive on the margin, is to try to build for other people and connect them together.” Connecting people is probably the most powerful thing you can do in life, and one of my favorite parts about doing what I do.

This is a great feed for the more serious posts in the AI field. There's plenty of space for shitposting and silliness, but sometimes you just want to read about new papers and stuff.

Hey, #ruby folks! I've been one of the #RubyGems maintainers for the last decade. Ruby Central has forcefully taken control of the RubyGems organization on GitHub, the `rubygems-update` and `bundler` gems on rubygems[.]org, and more. You can read the details here: pup-e.com/goodbye-ruby...

Had a blast talking about my favorite MCP (and agentic in general) antipattern on the Real Python Podcast: converting REST APIs directly into MCP servers.

I was inspired to write about it. There are some really cool but I think understated possibilities that the team built to support with the registry.
