WebMCP is shaping up as a powerful new standard for AI-driven browsing

WebMCP is shaping up as a powerful new standard for AI-driven browsing, but adoption is still near zero. The July 2026 update shows Chrome origin trials live, Edge support behind a flag, and a spec shift to document.modelContext. While big names like Expedia and Shopify are piloting, no mainstream AI agent yet consumes WebMCP tools — making the next 12 months the critical window for early adopters.

Purpose: Lets websites register typed JavaScript functions that AI agents can call directly, instead of scraping the DOM or relying on brittle computer vision.

How It Works:

Pages define tools with names, descriptions, and JSON schemas.

Agents call these tools like functions, inheriting the user’s session.
