Show and tell: Reasonix Browser Bridge — control your browser via MCP

[liutingqiu]

Reasonix Browser Bridge — an open-source browser automation extension for the Reasonix ecosystem.

I built a Chrome/Edge extension + MCP server that lets Reasonix (or any MCP client) control your browser directly.

What it does

• 25 MCP tools: tabs (list/open/activate/close/reload), cookies (full read/write), arbitrary JS execution on any page (via CDP, bypasses page CSP), screenshots, downloads, proxy switching, browsing-data cleanup, extension management, history, bookmarks, notifications
• Multi-browser: install once per browser (Chrome & Edge), every instance auto-connects to a local bridge (ws://127.0.0.1:8747)
• Full permissions — it is an automation bridge, so it can do anything the browser can

Why

The MCP plugin mechanism in Reasonix is solid, but there wasn't a first-class "control the browser" option. This fills the gap with zero configuration: install the extension → npm start → register in config.toml → done.
