The MCP registry lookup is no longer blocked by the nonessential-services privacy setting.

The "block nonessential services" privacy setting no longer blocks the connector directory (Anthropic MCP registry) lookup. It now covers three outbound fetches instead of four: connector favicons, the artifact-preview iframe, and the MCP Apps widget iframe.

Added since A small documentation edit on Telemetry and egress touched a line naming disableNonessentialServices after this was published. With `disableEssentialTelemetry`, `disableNonessentialTelemetry`, `disableNonessentialServices`, and `disableAutoUpdates` all set to `true`, the desktop application makes **no outbound connections to Anthropic-operated hosts at runtime**. … third-party/claude-desktop/telemetry see the edit
