WebMCP: AI Functionality for the Browser

The provided sources introduce and detail WebMCP (Web Model-Context Protocol), an emerging web standard designed to enable seamless, structured communication between AI agents (like LLM-based assistants) and web pages. Building upon the broader Model Context Protocol (MCP) standard, WebMCP allows web developers to expose specific front-end JavaScript functions as "tools" that AI agents can invoke directly, moving away from brittle UI scraping or simulation. The text examines the technical implementation, primarily within the Chromium (Blink) engine, describing the required JavaScript API surface, browser-side registry, and security protocols requiring explicit user consent to ensure safe human-in-the-loop collaboration. Finally, the sources outline use cases, such as reliable form filling and improved accessibility, while noting that the protocol is in the incubation and W3C standardization stage.
