This PR introduces the WebMCP Window Agent (demos/window-agent/), a meta-demo showcasing how an in-page agent can discover and execute WebMCP tools across separate browser windows—including both standard popup windows (window.open) and Document Picture-in-Picture windows (window.documentPictureInPicture.requestWindow) using window.document.adoptNode(iframe).
Note on current specification status: Please note that cross-window tool discovery is not yet supported in WebMCP, as tool discovery is currently limited to a single traversable navigable. See webmachinelearning/webmcp#227 for ongoing discussion on expanding tool discovery across navigables.
