Chrome’s WebMCP origin trial is live · Gemini in Chrome will call website tools
WebMCP — the new W3C standard from Google and Microsoft — lets websites hand agents real tools instead of making them guess at buttons. We audit how agent-ready your site is and tell you exactly which tools to build.

Aligned with the W3C draft, Chrome docs & Lighthouse agentic checks
01 / The shift
Google and Microsoft co-authored WebMCP, now a W3C Web Machine Learning Community Group draft. Chrome is running a public origin trial (Chrome 149–156), Lighthouse added an agentic browsing audit category, and Cloudflare scores every site’s agent readiness. Booking, shopping, and research increasingly happen through agents — and an agent that can’t use your site buys from one it can.
*Cloudflare scanned 200,000 sites: only ~4% passed its agent content-accessibility check.
// Without WebMCP an agent sees pixels. With it, it sees this:
document.modelContext.registerTool({
name: "book_table",
description: "Reserve a table at the restaurant",
inputSchema: {
type: "object",
properties: {
date: { type: "string", format: "date" },
guests: { type: "number" }
}
},
execute: async ({ date, guests }) =>
reserve(date, guests)
});// One tool call replaces ~12 fragile clicks.

04 / FAQ
A WebMCP audit assesses whether AI agents — like Gemini in Chrome or browser automation agents — can discover, understand, and act on your website. It checks WebMCP tool registration (document.modelContext), llms.txt, AI crawler access in robots.txt, Schema.org structured data, server-rendered content, and security requirements, then recommends which WebMCP tools your site should expose.
An agent-ready website is one AI agents can use reliably: its content is readable without executing JavaScript, its meaning is machine-legible through structured data and llms.txt, and its key actions — search, booking, add-to-cart, contact — are exposed as callable WebMCP tools instead of buttons an agent has to guess at.
SEO makes you findable by search engines; WebMCP makes you usable by agents. As browsers ship agent features (the Chrome WebMCP origin trial is live in Chrome 149–156), sites that expose tools get transacted with directly, while sites that don’t force agents into slow, error-prone clicking — or get skipped for a competitor that is agent-ready.
