A CLI to report potential MDX v3 parsing errors found in your content, using the same setup as Docusaurus v3 uses.
Run this command on your site:
npx docusaurus-mdx-checker
The output should give you an estimate of how many of your documents are incompatible with MDX v3 (Docusaurus flavor).
This tool was created to help Docusaurus v2 users (using MDX v1) upgrade incrementally to Docusaurus v3 (using MDX v3), or estimate the amount of work needed.
