CloudFlare Previews Automatic WebMCP Support for Web Pages
↗
Cloudflare released a developer preview that lets sites on its platform expose a WebMCP interface to browser-based AI agents through a dashboard toggle, replacing fragile scraping with structured tool calls.
If you operate a site behind Cloudflare, you can now give AI agents a structured way to call your site's functions without writing custom integration code or modifying your pages. The feature is early, only Chrome 145+ supports the underlying WebMCP standard, and the tool pack library is limited to two packs at launch.

Cloudflare injects a bridge.js module at the edge via HTMLRewriter, composing selected tool packs into a single tool list registered with the browser's WebMCP API.
Two tool packs ship in the preview: Content Credentials for reading C2PA image provenance metadata and Site MCP server for proxying existing server-side MCP tools to in-browser agents.
The WebMCP standard itself is still a preview and only works in Chrome 145+, making production use contingent on browser adoption.
