# The census

Home > Census

A monthly measurement of how much of the web an agent can actually use. Every
figure is probed rather than declared, carries the population it was measured
over, and is dated.

- **September 2026** (20 Sep 2026): Wix and Shopify serve a live MCP endpoint for every site they host, and the MCP server card finds none of them.

- **August 2026** (30 Aug 2026): The first crawl-wide count of agent-facing files: llms.txt on 1,896,102 registrable domains, an MCP server card on 80.
