Struct SubscriptionsAcknowledgedNotification 

pub struct SubscriptionsAcknowledgedNotification {
    pub params: SubscriptionsAcknowledgedNotificationParams,
    /* private fields */
}

Latest MCP Protocol 2026_07_28 Sent by the server to acknowledge that a {@link SubscriptionsListenRequestsubscriptions/listen} subscription has been established and to report which notification types it agreed to honor. This notification MUST be the first message the server sends carrying the subscription’s ID in io.modelcontextprotocol/subscriptionId. The server MUST NOT send any notification on the subscription before acknowledging it. On stdio, where every subscription shares one channel, this ordering is defined per subscription ID and not per channel: messages belonging to other subscriptions MAY be interleaved before it.
