# Google-CloudVertexBot

Google says Google-CloudVertexBot performs crawls a site owner requested in order to build Vertex AI Agents. It does not affect Google Search. On this crawler, a robots.txt rule matches if it names Google-CloudVertexBot or Googlebot; Google says matching one of a crawler's tokens is enough.

- Operator: Google
- Kind: owner_requested
- robots.txt: obeys. The vendor says this crawler obeys robots.txt on automatic crawls.
- HTTP user-agent: Google publishes the HTTP substring Google-CloudVertexBot, not one full browser string, on the common-crawlers page.
- Also matches: Googlebot
- IP list: https://developers.google.com/static/crawling/ipranges/common-crawlers.json

## JSON

`curl -s https://whosthatbot.com/v1/crawlers/google-cloudvertexbot`

## Check this token

tools/call with name check_robots is the same check at https://whosthatbot.com/mcp. Send `Content-Type: application/json` and `Accept: application/json, text/event-stream`. The pasted file disallows Google-CloudVertexBot on `/docs` and allows `*`. The call does not fetch a host.

```
curl -s https://whosthatbot.com/mcp -H 'content-type: application/json' -H 'accept: application/json, text/event-stream' -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"check_robots","arguments":{"robots_txt":"User-agent: Google-CloudVertexBot\nDisallow: /\n\nUser-agent: *\nAllow: /\n","path":"/docs","ids":["google-cloudvertexbot"]}}}'
```

That call returns fetched_target false. This row is disallow via group Google-CloudVertexBot, rule Disallow: /. also_matches_tokens lists Googlebot and is not merged into this decision.

Each card paraphrases the linked vendor page and was checked on source.retrieved. This is not legal advice. robots.txt is a request from the site owner. Botcard does not fetch third-party sites and does not suggest ways around a disallow rule.
