AI Newsletter · Three Issues Per Week
Three issues a week. Real tools. Real workflows. No hype.
Every Monday, Wednesday and Friday, The Anthropic Stack delivers the signal that matters from the AI developer ecosystem. Claude Code, MCP servers, AI agents, automation workflows and the tools reshaping how work gets done.
What you get
Three issues.
Every week.
The Signal
The biggest AI story of the week, explained properly. What happened, why it matters and what to do about it. Plus a curated stack of the most important developments across the ecosystem.
The Build
Hands-on. Step-by-step build guides, prompts that actually work, honest tool reviews and before-and-after workflow transformations. Every issue is designed to finish in under 30 minutes.
The Queue
Five links worth your weekend. The best writing, tools and conversations from across the AI landscape, each with context on why it deserves your attention.

Why this newsletter exists
The AI space has
a signal problem.
There are thousands of announcements every week. Most are irrelevant. Some are transformative. The difference between the two is not obvious unless you are building with these tools every day.
The Anthropic Stack exists because no one was writing about the Claude Code and MCP ecosystem with the depth it deserves. Model Context Protocol has reached 97 million monthly SDK downloads. Claude Code is on a billion dollar run rate. The developer tooling around Anthropic's ecosystem is moving faster than any other stack in AI.
Someone needed to cover it properly. Not with breathless hype. Not with surface-level summaries.
With the perspective of someone who builds production systems with these tools and understands what actually matters for the people using them.
About the author
Gareth
Editor, The Anthropic Stack
Every issue is written by someone who builds production AI systems daily and understands what actually matters for the people using them.
What readers say
The only AI newsletter I actually open every time it arrives.
Finally, someone writing about AI tools for people who use them at work, not just people who talk about them on Twitter.
Wednesday builds have saved me hours. Practical, tested, no fluff.
Frequently asked questions
Got questions?
Is The Anthropic Stack only about Anthropic and Claude?
No. The name reflects where the newsletter started, but coverage spans the full AI landscape. Claude, ChatGPT, Gemini, open source models, automation tools, MCP servers and everything in between. If it matters to people building with AI, it belongs here.
How often do you publish?
Three times a week. Monday, Wednesday and Friday. Each issue takes under five minutes to read.
Is it free?
Yes. The core newsletter is free and always will be. A paid tier with deeper analysis and exclusive content is planned for later in 2026.
What makes this different from other AI newsletters?
Specificity. Most AI newsletters cover announcements. The Anthropic Stack covers what works. Every issue is written by someone who builds production AI systems daily. The perspective is practical, opinionated and grounded in real usage.
Can I sponsor The Anthropic Stack?
Yes. Sponsorship opportunities open from month four. Reach out to theanthropicstack@proton.me for the media kit.
