I've been playing with building a personal assistant meets browsing assistant for mobile web and had to experiment with WebMCP as part of the experience. It's quite amazing to see how much better the experience can be when the browsing agent perform tasks instantly instead of wasting turns with navigating and interacting with the page to perform a task. Where as the baseline for the browsing agent I've built can navigate around and perform tasks for me, it take several turns, spends more tokens and takes more time to perform that. After implementing WebMCP into the agent harness it tasks that took several turns became instant (for pages that exposes the features). We are only at the beginning of the spec, but this is going to be amazing as more apps and sites support this feature. @ChromiumDev is building something amazing here!

A feature I don't think anyone asked for. Changing scrollbar colour based on scroll-position. Use CSS scroll-based animations, custom CSS properties and Demo: colourful-scrollbar.val.run Code: val.town/x/paulkinlan/c… Probably doesn't work everywhere and probably shouldn't be used anywhere

Nice post by @andreban - bandarra.me/posts/point-an… - it made me think if there is a tool that is "set_preferences" that the LLM will call (with the users permission) - we could start to tailor UIs even more to the user.

Your AI agent can do more than just write code. We're exploring how the DevTools MCP server connects your model to Chrome DevTools for live debugging, from fixing high INP to testing complex forms → goo.gle/4kBqqpX

Token usage in LLM applications is a huge topic. It dictates response speed, cost efficiency - or the quota left on your plan 😄 🪫 Learn how the Chrome DevTools team squeezed a full Performance trace into Gemini in DevTools developer.chrome.com/blog/designing…

#MCP is great for agent-to-tool communication. But 50 sequential browser operations = 50 round trips = latency and token overhead. I opened an RFC for a CLI wrapper that lets agents batch operations via bash scripts. github.com/ChromeDevTools… #AIagents
