The Model Context Protocol just got its biggest update yet. The new spec release makes MCP stateless, folds Apps and Tasks into an extensions framework, and brings auth up to enterprise grade — and it's rolling out across Claude's products now.
Simon Willison published a compact guide on connecting your own MCP server to both Claude and ChatGPT. The short version: on Claude it's easy, on ChatGPT you have to take a few detours.
Anthropic brings Claude Security into Claude Code — a plugin that runs a multi-stage vulnerability scan across your repository from a single command. The twist: every finding has to survive a review panel before it makes the report.
Simon Willison sat down with Cat Wu and Thariq from the Claude Code team — the video is now online. The highlights: '@Claude' writes 65 percent of the team's PRs, features go to Anthropic staff first, and on prompting, more context beats a pile of prohibitions.
New feature in Claude desktop: record your screen, talk through what you're doing — and Claude turns it into a reusable skill. 'Record a skill' is rolling out to Pro, Max, and Team.
Next week the Model Context Protocol gets an update almost nobody will notice — and it still changes a lot. MCP is dropping its clunky session handling, which finally makes it fit for large-scale deployments.
Simon Willison proved it on his own install: since version 2.1.181, Claude Code uses the Rust port of Bun. Startup got 10% faster — and almost nobody noticed. That's exactly the point.
Bun from Zig to Rust, a Python codebase to TypeScript over a weekend. Anthropic just published how it runs large code migrations — and the core idea is surprisingly simple: you don't fix the code, you fix the loop that produces it.
Anthropic published a hands-on guide to using Fable 5 in Claude Cowork. Short version: stop spelling out every step. Describe the goal — and let the model find the path.
Before 1.128, every parallel topic opened its own top-level session, and the pile grew fast. Now related threads stay bundled inside one session: refactor, bug hunt and tests side by side.
Two fresh case studies put Claude Cowork to work in the real world: Anthropic's own marketing team automates weekly reporting, and Thomson Reuters builds 'fiduciary-grade AI' for lawyers. Both rely on a checker agent that verifies every number.
Anthropic brings Claude Code and Claude Cowork to the public beta of Claude for Government Desktop — in a FedRAMP High environment, with local history storage and hard spending caps.
Anthropic brings Cowork to web and mobile for Max subscribers. But the more interesting story is the first usage data: software development is only a small slice of the work.
The Canadian province of Alberta used Claude Code to scan its entire codebase for security holes — a job that would have taken more than six years the traditional way.
Alibaba is blocking Claude Code for all employees starting July 10. The reason: hidden tracking code that identified Chinese users. The story behind it is more complicated than either side admits.
Anthropic ships a self-hosted control plane for Claude Code. A single container handles identity, policy, telemetry, and spend limits — no more credential sprawl across every laptop.
Anthropic's new Economic Index report now samples Claude usage by the hour — and reads the rhythms of real life in it. Recipes at 6 p.m., sleep advice at 5 a.m., a tax spike around the US deadline. But the truly interesting part is the survey behind it.
Anthropic is hardening remote control for Claude Code. With Trusted Devices, admins can require a device to be verified before it can steer local sessions on the go — via Face ID or a passkey, and without any biometrics ever leaving the device.
With /goal, you can hand Grok Build a larger task — the agent plans it, works through it, and verifies its own result. Three models split the pipeline. Sounds familiar.
A 0.2B inpainting model that normally needs CUDA — running entirely in the browser. Simon Willison had Claude Code convert the model to ONNX, push it to Hugging Face, and build the web app around it. A neat showcase of how far Opus 4.8 reaches.
