In September 2026 we entered The WebMCP Challenge, a ten-day hackathon on Devpost backed by Cloudflare, Vercel, Shopify, Google Chrome, Render and Netlify. The brief was to build something that becomes meaningfully better when people and their AI agents can use it together.

WebMCP is an emerging browser standard. It lets a website hand a visitor's AI agent a small set of well-defined tools, so the agent can complete a task directly instead of guessing its way through menus and forms.

Our entry: the Office of Kaiju Affairs

A fictional government agency site of fifty-one pages, published by RIFT CMS. The idea we wanted to test: the agent layer should not be hand-coded page by page. It should be generated by the content management system at publish time. RIFT emits a manifest describing every page, service, eligibility rule and form, plus one script tag. That is enough to give the site seven tools — search, page summaries, a list of services, requirements, an eligibility check that cites the rule it applied, permit-form prefill, and office information. Publish a thousand more pages and the agent layer grows with them.

The site also includes an Arena: a side-by-side race between an agent guessing through the user interface and an agent using the site's published tools, on the same three citizen tasks. It reports what it measures, including where a fix produced no change.

Everything a regulated customer would expect still holds. Content is authored and approved in RIFT by named people; the agent layer is a by-product of publishing, never a second source of truth.
