SpidexLab's Multi-Tenant Browser MCP 🚀

🌟 SpidexLab's Custom Fork for Autonomous Agents - This is a modified version of the Chrome MCP Server, specifically re-architected to support Multi-Tenant Tab Multiplexing and Concurrent Agents.

This is a specialized fork. For the original upstream project, please visit hangwin/mcp-chrome.

📖 Documentation: English

🎯 What makes this fork different?

The original Chrome MCP Server is an incredibly powerful tool that exposes Chrome browser functionality to AI assistants. However, it was built with a 1-to-1 connection limit in mind (one agent controlling one browser session).

The SpidexLab Modification (V3: The Multiplier): We have modified the native server bridging logic and extension messaging architecture to support a multi-tenant execution queue. This allows multiple autonomous AI agents to connect to the same browser instance concurrently. Each agent operates in its own isolated browser tab context, allowing 2, 5, or 10 agents to parallelize web research and automation tasks without connection resets or state collisions.
