Google-CloudVertexBot crawls sites at the request of Google Cloud customers building Vertex AI Agents and search applications. It is triggered by customer configuration rather than by Google's own indexing pipeline.

The bot is documented among Google's crawlers and respects robots.txt rules set for its token; blocking it does not affect Google Search or Googlebot.
