Bringing the power of MCP to the web

Overview

WebMCP is a protocol that brings MCP to the browser, letting websites expose their JavaScript functions, APIs, forms, or page state as structured MCP tools that AI agents can call directly. It offers tab and extension transports so AI can interact with a site deterministically while respecting user authentication. The API has been accepted as a W3C deliverable, and this repository is kept for historical reference.
