Session Bridge MCP Server

A free MCP (Model Context Protocol) server that exposes authenticated browser-session automation: session_ tools that run in the user's own Chrome profile and real logged-in session, which cloud browser APIs cannot do. A free standalone mode is also available; it launches a dedicated automation browser so the same session_ tools work without the extension or a license.

People who work with browser automation, chrome extension and playwright alternative and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
