Meta-ExternalAgent crawls to train and improve Meta's AI products, including Llama models and Meta AI. It honours robots.txt directives.
Meta-ExternalAgent gathers web data used to train and refine Meta's AI, spanning the Llama model family and the Meta AI assistant threaded through Facebook, Instagram and WhatsApp. It honours robots.txt, so a single rule covers an enormous distribution surface. The trade is reach against attribution: presence in Meta AI's answers can be large, but it arrives as model knowledge, not a linked citation.
Meta publishes neither an IP-range feed nor a reverse-DNS footprint for Meta-ExternalAgent, so there is no way to confirm it by network identity. Treat every request carrying the Meta-ExternalAgent user-agent as an unverified claim, and judge it on what it does rather than the name it gives.
Recommended: keep. Meta-ExternalAgent feeds Llama and Meta AI across Facebook, Instagram and WhatsApp — an enormous surface — but presence there lands as model knowledge, not a linked citation, so the trade is reach against attribution.
If you do choose to act in robots.txt (which crawlers honour but don't enforce):

Will I get referral traffic from Meta-ExternalAgent?
No. It's a training crawler, so the trade is reach against attribution — you may be reflected in Meta AI's answers, but as learned knowledge rather than a clickable source.
