WebMCP

The currently open webpage provides tools directly inside the browser. In other words, it is a browser API that lets websites expose “the functions I provide” to AI agents as structured tools.

Chrome 146 includes an early preview of WebMCP, accessible via a flag, that lets AI agents query and execute services without browsing the web app like a user.Services can be declared through an imperative navigator.modelContext API or declaratively through a form. pic.twitter.com/UaUplZ8Q28— Maximiliano Firtman (@firt) February 9, 2026

WebMCP

WebMCP is an open source JavaScript library that allows any website to integrate with the Model Context Protocol. It provides a small blue widget in the bottom right corner of your page that allows users to connect to and interact with your webpage via LLM or agent.

Instead of directly manipulating the DOM, this is an attempt to have sites explicitly provide interfaces for agents. Websites define structured tools to clearly tell AI agents "where and how to interact." This enables more accurate, faster, and reliable agent workflows compared to simple DOM manipulation approaches.
