A new JavaScript interface that allows web developers to expose their web application functionality as "tools", i.e. JavaScript functions with natural language descriptions and structured schemas that can be invoked by AI agents, browser assistants, and assistive technologies. WebMCP enables collaborative workflows where users and agents work together within the same web interface, leveraging existing application logic while maintaining shared context and user control.

It might be hard to read the tea leaves on this one (so goes developer-focused launches), but the fact that WebMCP is being advanced by both Google and Microsoft is a big deal, and even moreso now that Google is shipping it in Chrome in early preview:
Expect to see this more widespread by Google I/O in June.
This fills a real gap. Most agent tooling assumes APIs exist, but a huge chunk of useful functionality is trapped behind web UIs with no API. The collaborative model where user and agent share the same interface is the right mental model too - agent as co-pilot, not separate automation. What is the approach for handling auth state across agent sessions? Cookie persistence or re-auth per request?
Something I'm wondering is how much better would this WebMCP be than utilizing, for example, Claude codes' ability to do a search? What does this really bring to the table?
