Shopify added WebMCP tools to its checkout on September 28, 2026. An AI agent running in the buyer's browser can read the checkout, change the address, delivery option, discount codes, and payment choice, and place the order once the buyer approves it. Merchants do not have to configure anything.

Willison reports that OpenAI announced ChatGPT Work on July 9, 2026 and has been changing it since, without documenting what the agent can do. He spent weeks testing it, then had the product describe itself: 223 registered tools and 44 skills, six of the tools his own. The inventory shows a code sandbox with open internet access, a full headless Chrome, and a filesystem shared across sessions.

When a task needs a website, a browser opens in the side panel of the desktop app and Claude drives it. Anthropic's design decision is the whole story: it is Claude's browser, not the user's, so it never sees their tabs, bookmarks or passwords. Rolling out to Pro, Max and Team over the week from August 26.

Claude in Chrome has left the pilot and is available on every paid Claude plan. The change that matters is not availability but autonomy: Claude now approves safe actions itself, using the same mechanism as Claude Code, instead of stopping for every click. Anthropic published the prompt injection numbers behind that decision, and the one worth reading is the baseline: before extra safeguards, attacks that reached Opus 5 succeeded 3.8% of the time.

Both drive a web browser, both stop before the step that cannot be undone, and their lists of stopping points are nearly the same. The difference is what each assumes about the session it runs in: one is built on the accounts you are already signed into, the other tells you to give it a browser with no credentials in it. That single assumption decides which of the two belongs anywhere near your work.

Google's agent can now drive the desktop version of Chrome, using accounts you are already signed in to and passwords saved in the browser. It books property viewings, prepares flight searches, and fills in forms, handing the task back to the user to finalize a payment, accept terms, or create an account. This is the same pattern that has settled in with Claude and the rest: the agent does everything up to the step that cannot be undone, and a person confirms that step.
