September 20 accelerator census: two browser contexts →

How we read the evidence.

This is a dated snapshot, not a live monitor. Every production candidate is searchable, including sites where no tools were found. A registration shows that a page exposed a tool; it does not establish that an agent used it.

Two populations, counted separately.

Platform-wide rollout
673,432
Registered without flags
2,420

Platform-wide rollout. Shopify Liquid storefronts carrying a valid token in the August 2026 crawl. This platform-wide population is counted separately from the individually inspected sites.

Registered without flags. Individually inspected sites that registered tools for an anonymous visitor. This includes native registrations and polyfills, labelled separately below.

Eight observed states.

Eight observed states.
StateSitesWhat we saw
Native2,236Tools registered for an anonymous visitor in stock Chrome, with no flags set.
Polyfill184A JavaScript shim registers the tools, so Chrome’s own agent never sees them.
Primed421An edge agent bridge is installed with the WebMCP pack switched off. Two switches from live, not one: the pack, then an origin-trial token the platform does not mint.
Tools, no trial token1,336Registers tools, and we did not detect a Chrome origin-trial token. Until WebMCP reaches stable, a token decides whether the browser exposes them.
Token, no tools101Serves a valid origin-trial token; we saw no tools register on the surfaces tested.
Gated641WebMCP evidence sits behind a login or a bot wall.
No evidence1,970No WebMCP evidence on the surfaces tested.
Unreachable45The domain did not respond.

The platform effect.

Pages firing Chrome’s WebMCP counter in the mobile crawl. Almost all of the increase came from Shopify; these page counts are separate from the directory’s site counts.

Method. Candidates came from HTTP Archive, Chrome use counters, origin-trial tokens decoded from headers and markup, urlscan, PublicWWW, GitHub, npm and public lists. Each was loaded in Chrome 152 twice: as a normal visitor, then with the trial forced on.

Trial context. At verification, Chrome required origin-trial enrolment to expose native WebMCP. Code, trial tokens and actual registrations are recorded separately. The observed tokens had an expiry of 17 November 2026.

Outside the directory. 249 demo, 140 tooling, 20 dev. SDKs, documentation, starter templates, registries, scanners and hackathon entries were tracked but excluded from the production-site list.

Reading the counts. Site totals describe this inspection set. The timeline counts pages, not sites. The platform-wide Shopify crawl is a separate population; these numbers should not be added together.
