Browser Use for AI Agents

Unlock true local-first browser automation for your AI agents.

The Local Multiplexed Browser MCP is a powerful Chrome extension designed to connect your local browser directly to AI code assistants and autonomous agents (such as Cursor, Claude Desktop, or custom CLI tools) using the Model Context Protocol (MCP).

If you are building or using AI web agents, you know the primary bottleneck: the Chrome DevTools Protocol (chrome.debugger) strictly limits attachments to one connection per tab. If multiple agents attempt to control your browser simultaneously, they collide, fail silently, or crash. Furthermore, existing solutions often force your local web traffic through proprietary, subscription-based cloud relays.

This extension, paired with the accompanying Local MCP Bun Server, solves both problems. It acts as a high-performance, multiplexed reverse proxy, allowing multiple concurrent AI agents to share a single Chrome instance safely, entirely on your localhost.
