How It Works

Understanding the WebMCP standard

What is WebMCP?

WebMCP is a W3C web standard from Google and Microsoft. It lets websites expose structured tools to AI agents. Instead of scraping the DOM or guessing how forms work, your site tells agents exactly what it can do, how to call it, and what it returns.

Why It Matters

Traditional web automation is brittle. Agents parse pixels, guess at button meanings, and break when layouts change. WebMCP fixes this with a schema-driven protocol. Each tool has a name, description, typed input schema, and structured output. Agents discover what's available and call it directly.

Structured Result

The agent discovers tools registered on the page, inspects their schemas, calls the right tool with structured arguments, and gets back a typed result. No DOM interaction needed.

WebMCP is available in Chrome 146 Canary behind a feature flag. The spec is being finalized through W3C community incubation.
