Model Context Protocol (MCP) server that provides direct access to your browser's open tabs content. No additional fetching or authentication required - simply access what you're already viewing.

Key Features

• Direct browser tab access - No web scraping needed, reads content from already open tabs

• Content optimized for AI - Automatic content extraction and markdown conversion to reduce token usage

• Active tab shortcut - Instant access to currently focused tab without specifying IDs

• MCP listChanged notifications - Follows MCP protocol to notify tab changes (support is limited in most clients)
