Web MCP
A monorepo implementing the Web Model Context Protocol for browser integration.
The Web MCP specification defines a navigator.modelContext API that allows web pages to register tools for AI assistants to discover and invoke. This repo provides:
- An MCP server that connects AI assistants to browser tabs
- A Chrome extension that exposes page tools to the MCP server
- A polyfill for the
navigator.modelContextAPI - A registry of pre-built tools that can be injected into pages (optional)
