You were wrong about MCP being dead, and you probably ignored WebMCP. Now it's time to skill up.
Agents are increasingly part of every workflow we do, but many websites and app haven't adapted yet. first-party integrations ship without a UI. Screen scraping is expensive. Computer use is too slow and brittle to get real work done. We want your app in our agents.
WebMCP is a new browser spec that lets websites and apps expose their features as structured, callable tools. Run it inside the user's tab, so it uses the browser's existing auth and security model.
In this talk, Wes will show how WebMCP enables co-browsing, natural-language input and batch processing. We're human, we still want to use websites and apps. We just want to use them with our agents too!
