Is AdGuard Browser Assistant safe?
AdGuard Browser Assistant forwards the current tab URL and port to the AdGuard desktop app via native messaging on each tab switch.
When you activate or navigate to a tab, the extension sends the page URL and port number to the locally installed AdGuard desktop application through a native messaging channel named com.adguard.browser_extension_host.nm. This is how the browser extension communicates filtering state with the desktop app. No data is sent to remote servers; all communication stays on your local machine.

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 AdGuard Browser Assistant 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.
