Community Workaround for #22903 — CDP Connector for Browser Screen Access

This is a working workaround for the feature requested in #22903 (bidirectional visual streaming / screen share for Claude Code), specifically for browser-based use cases.

What this solves

For anyone needing Claude Code to "see" and interact with a browser — web CTF challenges, live app debugging, form automation — the Chrome DevTools Protocol (CDP) provides programmatic access that is actually better than pixel-level screen sharing for these cases. You get structured DOM data, not screenshots to interpret.

How it works

Launch Edge or Chrome with the debug flag:

Start-Process msedge -ArgumentList "--remote-debugging-port=9222","--user-data-dir=C:\Temp\edge-debug","--remote-allow-origins=*"

Then Claude drives the browser via a Python CDP connector:

# Read active tab content
python cdp_connector.py --text

# Execute JavaScript in page context
python cdp_connector.py --js "document.cookie"

# Click an element
python cdp_connector.py --click "#submit"

# Fill a form field
python cdp_connector.py --fill "#username" "admin"

# Navigate
python cdp_connector.py --goto "http://target"

# Dump cookies
python cdp_connector.py --cookies

# Clean tab screenshot -> saved to fixed path Claude can Read
python cdp_connector.py --screenshot

Claude reads DOM, executes JS, interacts with forms, grabs cookies and session state — all without native screen-sharing support in Claude Code.

For non-browser content (VM windows, binary challenge GUIs), a companion screen_watcher.py using mss handles pixel-level capture to a fixed path that Claude reads with its Read tool.

Relation to #22903

This doesn't replace the native feature request — full bidirectional screen streaming would cover all apps, not just browsers. But for the majority of web-focused use cases this works right now with no Claude Code changes required.
