Cloudflare updated Kitesurf, its browser for AI agents, adding WebMCP support, more web standards (CSS Layout, CSSOM, CSS Typed OM, custom elements, URL-based module resolution, JSON modules, import maps), improved iframe behavior, and full Browser Run API coverage including CDP, Playwright, Puppeteer, and MCP. The browser now passes over 730,000 Web Platform Tests, up 500,000 since launch, and includes efficiency optimizations for the agentic loop.

## Evidence
