# WebMCP Bridge Server Chrome Extension

A Chrome extension that bridges tools registered on `navigator.modelContext` to desktop AI clients (Claude Code, Cursor, etc.) via MCP.
A Chrome extension that bridges tools registered on `document.modelContext` to desktop AI clients (Claude Code, Cursor, etc.) via MCP.

> Note: This extension is a workaround for now. Once Chrome natively supports some bridge solution, I'll deprecate this extension.

## How it works

Your React app registers tools using `webmcp-react`. The extension picks them up from `navigator.modelContext`, aggregates tools across all active tabs, and exposes them through a local MCP server that clients connect to over stdio.
