Duplicate MCID Report for PDFs

Duplicate MCID Report is a free, local validation action that finds duplicate MCID entries in a tagged PDF. A duplicate MCID can make screen readers repeat or skip content, so catching it matters for PDF/UA compliance. It runs as a Java CLI tool. You can also scan a single file or a whole folder at once.
