Cloudflare has added WebMCP support to Kitesurf, its browser built on Workers for AI agents. WebMCP lets a website expose structured functions—such as a flight search or location change—so an agent can invoke them directly instead of trying to locate pixels and imitate mouse clicks.
The update also broadens the browser standards Kitesurf can handle, improves Document Object Model performance, and adds terminal-based rendering. Cloudflare says Kitesurf now passes more than 730,000 Web Platform subtests. Developers can test the WebMCP implementation in the public Kitesurf playground, where Cloudflare Radar exposes tools that an agent can discover and use programmatically.
Structured tools can make browser automation faster and less brittle, but they only help on sites that expose suitable functions; agents still need rendering and interaction support for the rest of the web. Kitesurf remains a specialized agent browser rather than a drop-in replacement for every human browsing feature. The update is available for experimentation now, giving developers a way to compare tool-based navigation with conventional screen automation on the same tasks.
