What is WebMCP?

WebMCP is a W3C web standard that lets websites expose structured tools to AI agents running in the browser.

Instead of AI agents scraping pages and clicking buttons, WebMCP provides a clean API — navigator.modelContext — where websites register tools with typed inputs and outputs. AI agents discover these tools and call them directly.

🌐

For websites

Add ~50 lines of JavaScript to register your tools. Your backend stays unchanged — WebMCP tools just call your existing APIs from the frontend.

🤖

For AI agents

Discover and call tools on any page. Structured inputs, structured outputs. No DOM parsing, no brittle scrapers.

🔗

vs. MCP

WebMCP runs in the browser (client-side). Traditional MCP runs server-side. They're complementary — many sites support both.

Currently available in Chrome 146+ Canary behind a flag. Backed by Google and Microsoft, on track for W3C standardization.
