Per Meta's crawler documentation, Meta-WebIndexer navigates the web to improve the quality of Meta AI's search results. It is a third Meta token alongside Meta-ExternalAgent and Meta-ExternalFetcher, and the newest of them.
You leave the index Meta AI answers from across Facebook, Instagram and WhatsApp — the largest assistant install base there is. A robots.txt that names the two older Meta tokens does not cover this one.
