People underestimate just how much we’re moving into the post-code way of shipping software and how high of a premium will be put on good taste, agency, and just the plain ability to communicate well.

@seldo.com is, once again, spot on.

Not exactly a great week for the "HTTPS lock means it's safe" guideline.

So, PHP-in-Rust is coming this weekend, yes?

Bad day to launch my PHP based certificate authority

My thoughts go to every cheap router or modem deployed somewhere that runs a PHP version from 1997.

“Ah so you’re planning to become the @kelseyhightower.com of MCP.” 🤞

Gave a talk on MCP and agent auth at FIDO Authenticate in San Diego - with some Twilio friends, of course. This place is amazing.

What is YOUR opinion on MCP?

Kenney’s assets are wonderful. I was looking at having a creative set for my personal blog OpenGraph images to be a bit more fun when they are randomly generated for each post, and Kenney’s work was my go-to.

They clearly just need a MCP server.

This spooky season, I am spending some time catching up and helping address your MCP-related bugs in Claude Code and Claude in general. If you see something, report it - and tag me! 1️⃣ Claude Code: github.com/anthropics/c... 2️⃣ Claude ecosystem: github.com/anthropics/c...

Three months and counting, still baffled this is not solved and instead there’s talk about easier monetization.

This is actually really cool - I’m a big fan of both the Halo Museum and @halopedia.org 🙌

I mean, a tool is a tool - would you refuse to use a power drill and instead bore holes with a gimlet everywhere? How about never using a word processor and write everything by hand on papyrus?

Raw thoughts, but I am kinda done with any kind of OS affinity. It all can just work now. den.dev/blog/operati...

In the next MCP animated adventure, I attempt to explain the difference between the different OAuth client registration methods we support at spec-level.

I am doing all my MCP explainers like this now. Just like the magical one talking about the magic of Enterprise-Managed Auth 🧙‍♂️

LOOK AT THIS ABSOLUTELY WILD RIDE

We’ve recently moved all PRs in the Model Context Protocol repositories to be limited to collaborators only. Too many low-quality submissions that someone still has to review and triage. We ask that folks start engaging with us directly on Discord for new proposals first.

Few weeks ago got to visit Amsterdam and ramble about how shipping a new MCP spec is less intimidating than folks might assume 🤩 Full talk: dsc.ai/XmxeuL

So, uh... Kinda neat, Sonos now has a MCP server dsc.ai/sonos-mcp

One of the interesting observations that I had about my dev/computer usage in the past few years is that I became entirely OS/ecosystem-agnostic. There is absolutely no point in being super-attached to one platform, especially with a lot of tools now running really well cross-plat.

We’re cooking something with MCP 🎉 modelcontextprotocol.io/extensions/s...

Sometimes folks forget that MCP as a protocol is never actually "done" - we're constantly iterating on changes and releasing new revisions. For a protocol with this scope and adoption, I am actually pleasantly surprised how quickly we can move. dsc.ai/mcp-seoul-ke...

Got the chance to travel to beautiful Seoul 🇰🇷 to keynote the MCP Dev Summit. Wild to think that MCP is less than two years old 🤯 Full video: dsc.ai/mcp-seoul-ke...

i complained a lot about the mcp spec in the past but it's getting very good now

By the way, we just GA-d Enterprise Managed Auth (EMA) for MCP in Claude. No more auth prompts - just smooth SSO sailing for supported connectors.

We're about to be cooking with the new MCP roadmap 👉 dsc.ai/mcp-roadmap

For the past few months, I've been almost exclusively running everything in my life on Linux. Claude has been a massive unlock in helping me customize it and diagnose emerging issues quickly, and it doesn't feel as bad as it was even just a few years back. And surprisingly, it... just works?

Don't mind me, just reverse-engineering my way to playable Hunters in Halo: Campaign Evolved.

So this happened ✨

We are so back 💪 @simonwillison.net - if you have any feedback, all ears. Happy to make sure that the new spec and specs beyond it work well for devs.

The new MCP spec is now officially in flight 🛫 2026-07-28 is here, with a fully stateless protocol dsc.ai/new-mcp

How is Bluesky STILL relying on emails for 2FA in 2026? Yubikeys and authenticator apps have been invented, right? I didn't dream it up?

Brand new MCP SDKs just dropped for those of you who are brave enough to be on beta branches to test the new spec ✨ dsc.ai/sdk-betas

It's nice to see how in the past week alone ID-JAG picked up so much community traction. Who knew - people don't like to be annoyed by unnecessary auth prompts.

Plugged @standard.site integration for my blog and it's been a delight!

More people need to get comfortable with doing multi-agent adversarial analysis on their code.

I'm not kidding, Enterprise Managed Auth is probably the one thing that I am most excited about in the auth space this year. One SSO auth into Claude and you're logged into a bunch of other MCP servers automatically. Magic. You can sign your org up 👉 dsc.ai/emaw

very cool. here’s the link. it covers over a big sharp edge in authentication and makes MCP far more accessible to broad enterprise use blog.modelcontextprotocol.io/posts/enterp...

Unreal. Our today's MCP announcement is top of HN right now.

I am getting tired of overpermissioned tokens floating around, so the new MCP spec will be better for those that like step-up auth.

MCP is gonna be stateless starting the next protocol version ✨
