Struct SubscriptionFilter 

pub struct SubscriptionFilter {
    pub tools_list_changed: Option<bool>,
    pub prompts_list_changed: Option<bool>,
    pub resources_list_changed: Option<bool>,
    pub resource_subscriptions: Option<Vec<String>>,
    pub task_ids: Option<Vec<String>>,
}

Notification types a client opts in to on a subscriptions/listen stream (SEP-2575). Replaces the 2025-11-25 resources/subscribe RPC. The server MUST NOT send a notification type the client did not request.

Fields

tools_list_changed: Option<bool>

Receive notifications/tools/list_changed.

prompts_list_changed: Option<bool>

Receive notifications/prompts/list_changed.

resources_list_changed: Option<bool>

Receive notifications/resources/list_changed.

resource_subscriptions: Option<Vec<String>>

Resource URIs to receive notifications/resources/updated for. Replaces the former resources/subscribe RPC.

task_ids: Option<Vec<String>>

Task IDs to receive notifications/tasks for (SEP-2663). Unlike the list-changed flags this names individual tasks, so a client observes only the tasks it created. A client that sets this without declaring the io.modelcontextprotocol/tasks extension is answered with -32021.
