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.
Add ~50 lines of JavaScript to register your tools. Your backend stays unchanged — WebMCP tools just call your existing APIs from the frontend.
Discover and call tools on any page. Structured inputs, structured outputs. No DOM parsing, no brittle scrapers.
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.
