Hronaut Browser MCP

Hronaut is a visible, persistent Electron browser that exposes durable agent workspaces through MCP. It keeps the browser open independently of any individual AI session, so people can watch, pause, and take over while agents work in separate local browser profiles.

People who work with browser automation, chromium and coding agents and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
