Standard Chrome DevTools Protocol HTTP discovery endpoints that allow
tools like Playwright to connect using just the HTTP URL.
- /json/version returns browser info and webSocketDebuggerUrl
- /json/list returns array of connected targets
- Supports GET/PUT methods and trailing slashes for compatibility
Service workers, web workers, and iframes are now filtered out at the
server level, preventing Playwright from trying to initialize these
targets which caused timeouts and errors.
Standard Chrome DevTools Protocol HTTP discovery endpoints that allow
tools like Playwright to connect using just the HTTP URL without needing
to call getCdpUrl() first.

- Fixes issue where group wasn't created after debugger detach/reattach
- Store timer ID in window global so it can be cancelled
- Cancel pending timer when showAriaRefLabels is called again
- Cancel pending timer when hideAriaRefLabels is called manually
- Existing labels are removed before showing new ones
- Functions available in execute tool context
- Auto-hide labels after 5 seconds to prevent stale overlays
- Updated README with MCP usage example
- Example saves screenshot to /tmp
Uses elementsFromPoint() to check if element is blocked by opaque
overlays (modals, cookie banners, etc.). Skips elements where an
opaque element with pointer-events appears above the target in
the stacking order.
Correctly shows only visible, interactable elements.
