Browser Run - Browser Run adds WebMCP to Kitesurf and moves to document.modelContext
Cloudflare published a changelog entry titled "Browser Run adds WebMCP to Kitesurf and moves to document.modelContext." The entry is dated September 28, 2026, and is hosted on the Cloudflare Developer Platform changelog under the path /changelog/post/2026-09-28-webmcp-api/. The title states two changes: WebMCP has been added to Kitesurf, and the integration has moved to document.modelContext. The provided source text consists of the changelog page's title, URL, publication date, and styling markup rather than the body copy describing the change. As a result, the excerpt does not specify what WebMCP does within Kitesurf, which API surface document.modelContext replaces, whether the move is breaking, or any version numbers, dates, or migration guidance. The only source-anchored facts are the two named changes, the product names Browser Run and Kitesurf, the API name document.modelContext, and the publication date.
Developers using Browser Run's Kitesurf integration should note the shift to the document.modelContext API, per the changelog title.
