25Custom connectors and remote compute that members add reach whatever hosts they are configured with, so allow those case by case. Installs with telemetry turned off (see [Telemetry](/docs/claude-science/manage-on-devices#telemetry)) send no error reports, and blocking `o1158394.ingest.us.sentry.io` affects only error reporting, not the rest of the app.
