About

Harness-Engineered Browser Automation The MCP server that drives and guides AI agents through a real Chrome.

OpenChrome is an MCP server that controls your real, already-logged-in Chrome through the CDP — no middleware, no separate browser, no re-authentication. One Chrome process, many isolated tabs, 300 MB for 20 parallel lanes.

It is harness-engineered: the server doesn't just expose browser APIs, it wraps them with a hint engine, a circuit breaker, an automatic-recovery runtime, and token-efficient page serialization — so the agent makes fewer mistakes, recovers without "thinking", and burns far fewer tokens.

Install and point your MCP client at it — one command:
