AI assistants are getting better, but they still need context to work well with real tools and systems. The Model Context Protocol (MCP) is one way to provide that missing context. I wrote a guide on building and deploying your own MCP server:

Today I learned that @OpenAIDevs MCP client https://t.co/nhRPF6KVEf lists private_key_jwt for the token endpoint auth while the CIMD endpoint is actually public (auth=none). So your MCP OAuth must be able to skip private_key_jwt, if unsupported. MCP Related

With Agent Pilot you can create and manage agent skills in WordPress (just like blog posts) and publish them as standard Agent Plugins. Now with OAuth Pilot you get one-click authentication for all the MCP clients (Claude, ChatGPT, etc). No more application passwords! MCP Anthropic Related

Goodbye per-seat pricing. Per-user pricing has always rubbed me the wrong way. And in this agentic age, it feels downright antique. For the vast majority of the time Basecamp has been on offer, we never charged per-user. A few years ago we experimented with one pay-per-user plan, and that experiment just came to an end. And it couldn’t come at a better time. With the Basecamp CLI (and soon MCP, too), you can bring your agents to Basecamp as users too. Charging you for individual agents feels just as wrong as charging you for individual people. So today we have brand new pricing plans with NO… basecamp.com

Thanks @jasonlk! Lot to do still but: 1) @linear is used by pretty much by all major labs/ai companies out there 2) our MCP traffic grows 50% MoM 3) we have the most agent integrations and active usage than any platform like this (3rd party, in-house agents) 4) our AI revenue (loops, coding sessions) has grown about 500% per quarter 5) we are closing several public companies/enterprises each quarter to help them coordinate their agent work Quoting @HarryStebbings The Bull Case for Linear Being a $100BN Company: "Linear is the clear winner. They have built an agentic product first that allows us to build 100x more software, and that means 100x more features than ever before.

Co-founder and CEO of Stripe and co-founder of the Arc Institute. Keeps a personal site of reading lists, open questions and notes on scientific progress and how research is funded.
Between wallets for agents with @link (and @privy), MPP, Tempo, MCP, Stripe CLI, Agentic Commerce Suite, sandboxes, OpenRouter, Metronome/metered billing, Radar and distillation/token fraud, it turns out that "the economic infrastructure for AI" implicates a lot. Pretty much every layer of the Stripe stack is changing, and it’s a very good time to join if you want to build high-scale software that facilitates the practical deployment of this new intelligence.

It's becoming normal practice to plug your coding agent into tools like Slack and helpdesk software to find customer insights. Turns out it's super inefficient, because you're just fetching and smashing raw strings into your context repeatedly. So we released a new MCP server that solves that. MCP Related

Swedish programmer with degrees in engineering and psychology, author of Your Code as a Crime Scene and founder of CodeScene.
I still meet people convinced that AI coding tools will soon reach a point where code quality, design, and even architecture are "solved". So I ran a small ad-hoc experiment. I’ve been working on a CLI tool and let agents plan and implement a first functionally correct version. I provided strict instructions around testing strategy, workflows, and implementation constraints. But I deliberately removed the @codescene MCP and the safeguards I normally rely on. Unsurprisingly, the resulting code suffered from a ton of problems. It would have been a shaky foundation to continue building on. How s… MCP Related

MCP
Their words
I think the main beauty is, is that models are really good at calling Unix commands. So if you just add another CLI, that's just another Unix command in the end. And MCP is… That has to be added in training. That's not a very natural thing for the model. It requires a very specific syntax. And the biggest thing, it's not composable.

So, I think it'll be the same thing that that we'll see an increase in the scope that we're giving that we're willing to give to the robots as they get better and better where initially the scope might be like there is a particular thing you do like you're making the coffee or something. Uh whereas as they get more capable, as their ability to have common sense and a broader repertoire of tasks increases, then we'll give them greater scope. Now you're running the whole coffee shop.
