Is Violentmonkey safe?
Violentmonkey bundles a hardcoded Google OAuth client_secret that is transmitted to Google's token endpoint during Drive sync.
Violentmonkey is a userscript manager that runs user-supplied scripts on web pages. Its Google Drive sync feature uses a confidential-client OAuth flow unsuitable for browser extensions, embedding the client_secret directly in the extension bundle. The secret is sent in POST requests to www.googleapis.com/oauth2/v4/token during authorization and token refresh.

Shared hosts - 1 hostname
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data
Destinations our analysis observed Violentmonkey contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
