`Google-InspectionTool`

Google says Google-InspectionTool fetches for Search testing tools, including the Rich Result Test and URL inspection in Search Console. It has no effect on Google Search or other products. The page also lists Googlebot as a robots.txt token and says matching one of a crawler's tokens is enough. This check matches the whole token, so a group named Googlebot does not match Google-InspectionTool, and still reports the RFC 9309 decision. Common crawlers obey robots.txt on automatic crawls.

robots.txt token: Google-InspectionTool
Operator: Google
Kind: user_fetch
robots.txt: obeys. The vendor says this crawler obeys robots.txt on automatic crawls.

JSON

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

Check this token

tools/call with name check_robots is the same check at POST /mcp. The pasted file disallows Google-InspectionTool 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-InspectionTool\nDisallow: /\n\nUser-agent: *\nAllow: /\n","path":"/docs","ids":["google-inspectiontool"]}}}'

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