- Enriched deep DOM including iframes, shadow DOM, and listeners
- Interactive actions: click, keys, input value updates
- Navigation: open URL, back, forward, reload
- Remote browser via Docker with Selenoid and VNC
Prerequisites are Docker, Docker Compose, and Python. Run Selenoid Selenium Hub by pulling the required Docker images and executing docker-compose up inside the selenoid directory. Copy and adjust config-example.json, then configure it for your MCP client (Claude, VS Code, or Cursor). View the live browser at http://localhost:8080/.

Browser MCP over CDP
MCP Server that manages a Chrome browser using the Chrome DevTools Protocol (CDP)
This project exposes tools to navigate, interact and access a browser tab. The browser is controller using CDP and because of this:
1. the page is exported as full height screenshoot, accessibility tree and enriched deep DOM
1. the screenshoot captures whole page, not just the visible scrolled are
2. the accessibility tree contains most relevand parts
3. the enriched deep DOM contains
1. nested iframes, shadow DOM, pseudo-elements, etc.
3. per element attached listeners (for e.g. onClick, onKeyDown, etc), including the callback function code (for better or for worse)
4. per element relevant resolved styles
2. the page is interactable via click, keys and input value update functions
3. the page is navigable with basic open URL, back, forward and reload functions
The browser is running remotely on Docker using Selenoid with VNC enabled, available at http://localhost:8080/.
