Here is a python template that contains a copy of the base calibre code the the MDE uses. It returns the ID:VAL pair for a URL in the clipboard, if possible. You should be able to use it in a Copy to Clipboard action.

python:


def parse_clipboard_for_identifier():
    from calibre.ebooks.metadata.sources.prefs import msprefs
    from calibre.utils.formatter import EvalFormatter
	from qt.core import QApplication
	import re
    text = str(QApplication.clipboard().text()).strip()
    if not text:
        return None

    rules = msprefs['id_link_rules']
    if rules:
        formatter = EvalFormatter()
        vals = {'id' : '__ID_REGEX_PLACEHOLDER__'}
        for key in rules.keys():
            rule = rules[key]
            for name, template in rule:
                try:
                    url_pattern = formatter.safe_format(template, vals, '', vals)
                    url_pattern = re.escape(url_pattern).replace('__ID_REGEX_PLACEHOLDER__', '(?P<new_id>.+)')
                    if url_pattern.startswith('http:') or url_pattern.startswith('https:'):
                        url_pattern = '(?:http|https):' + url_pattern.partition(':')[2]
                    new_id = re.compile(url_pattern)
                    new_id = new_id.search(text).group('new_id')
                    if new_id:
                        vals = {}
                        vals[key] = new_id
                        return vals
                except Exception:
                    import traceback
                    traceback.print_exc()
                    continue

    from calibre.customize.ui import all_metadata_plugins

    for plugin in all_metadata_plugins():
        try:
            identifier = plugin.id_from_url(text)
            if identifier:
                vals = {}
                vals[identifier[0]] = identifier[1]
                return vals
        except Exception:
            pass

    return None

def evaluate(book, context):
	x = parse_clipboard_for_identifier()
	if x:
		return ', '.join(k + ':' + v for k,v in x.items())
	return ''
