Remarks

Introduced by the 2026-07-28 protocol revision (SEP-2575). The client uses this request to open a long-lived channel for receiving notifications outside the context of a specific request.

Per-request metadata (protocol version, client info, client capabilities, optional log level) flows through the inherited Meta property under the io.modelcontextprotocol/* keys.

Properties

Notifications

Gets or sets the notifications the client wants to receive on this subscription stream.

[JsonPropertyName("notifications")]
public required SubscriptionsListenNotifications Notifications { get; set; }

Property Value

SubscriptionsListenNotifications

Remarks

Each notification type is opt-in; the server MUST NOT send notification types the client has not explicitly requested here. The server's SubscriptionsAcknowledgedNotification reports the subset of requested notifications the server actually supports.
