261262## Disabling all Anthropic-bound connections
262263
263With `disableEssentialTelemetry`, `disableNonessentialTelemetry`, `disableNonessentialServices`, and `disableAutoUpdates` all set to `true`, the desktop application makes **no outbound connections to Anthropic-operated hosts at runtime**. The only required egress is `downloads.claude.ai` (for the VM bundle at session start) and your inference provider. With the [offline installer variant](/docs/third-party/claude-desktop/installation#offline-installation), `downloads.claude.ai` is not needed either, and your inference provider is the only required egress. Enabling [SSH remote sessions](/docs/third-party/claude-desktop/ssh-remote-sessions) adds `downloads.claude.ai` back for every device, because the offline installer does not include the remote-session components.
264With `disableEssentialTelemetry`, `disableNonessentialTelemetry`, `disableNonessentialServices`, and `disableAutoUpdates` all set to `true`, the desktop application makes **no outbound connections to Anthropic-operated hosts at runtime**. If Code sessions can use Web Fetch, also set [`skipWebFetchPreflight`](/docs/third-party/claude-desktop/configuration#skipwebfetchpreflight) to `true` (or add `WebFetch` to `disabledBuiltinTools`), because Claude Code in [Code](/docs/third-party/claude-desktop/code) sessions otherwise checks each fetched domain with `api.anthropic.com`. The only required egress is `downloads.claude.ai` (for the VM bundle at session start) and your inference provider. With the [offline installer variant](/docs/third-party/claude-desktop/installation#offline-installation), `downloads.claude.ai` is not needed either, and your inference provider is the only required egress. Enabling [SSH remote sessions](/docs/third-party/claude-desktop/ssh-remote-sessions) adds `downloads.claude.ai` back for every device, because the offline installer does not include the remote-session components.

265266These settings control only the application's telemetry, update, and non-essential service connections. They do not change how your inference provider handles conversation content at the endpoint. On Microsoft Foundry, the Claude models behind your inference endpoint run in an Anthropic-operated service, so conversation content reaches Anthropic-operated infrastructure regardless of these settings. See [Data handling by provider](/docs/third-party/claude-desktop/overview#data-handling-by-provider) on the Overview page.
