*Update October 2022*: As per [Remote debug Android devices](https://developer.chrome.com/docs/devtools/remote-debugging/), the `chrome://inspect/#devices` page has replaced the `Remote devices` debugger panel, breaking the JS in this answer and similar ones.

Just joined this StackExchange to show some appreciation for [Jeremy's answer](https://android.stackexchange.com/a/177760/258950) above, and also add the few lines of JS I used to export the tabs list (since copying with the cursor isn't ideal!)

As Jeremy said, select `Remote devices` under `More tools` on Chrome devtools `⋮` icon (top right of the panel):

- set up USB debugging on your phone (under `Settings`⇒`Developer options`, root not required)
  - note that you must enable the `Developer options` menu, it's hidden by default to protect users
  - on my phone this required tapping multiple times on the build number under `Settings`⇒`About Device`
- once this is done, plug your USB in and allow MTP connection
- when the Chrome devtools remote device panel is open, the phone will then request to allow USB debugging
  - you can opt to always trust the computer

Now the device is connected,

- open a 2nd devtools view on the devtools view from which you selected `Remote devices` to be able to retrieve the list of tabs using JavaScript
  - note that you must have devtools in pop-out mode (use the vertical ellipsis symbol in the top right of the panel) to be able to get this up, otherwise Command+Option+J(MAC) `Ctrl`+`Shift`+`J`(WINDOWS) will just close the first devtools panel.
- expand the list from the first few items to all tabs by clicking 'Show more'
- to script against the list, use the following few lines of code [entered in the console of the 2nd devtools window]

To export a list of all URLs open on Chrome for Android, I chose to just make the list into a markdown formatted text string and copy it to the clipboard

<!-- language: lang-js -->

    let bookmarkList = Array.from(document.querySelectorAll('.widget>.vbox'))
      .map(e => e.shadowRoot)
      .map(e => e && e.querySelector('.device-page-list'))
      .find(e => e);

    let bookmarks = Array.from(bookmarkList.querySelectorAll('.vbox'))
      .map(e => `[${e.querySelector('.device-page-title').innerHTML}](${e.querySelector('x-link').innerHTML})`);

    copy(bookmarks.join('\n'));

You will then have a list on your clipboard looking like this:
