String	sessionId()	The session this event belongs to.
default long	sseEventId()	SSE event ID (for replay), or -1 if not assigned.

Method Details

sessionId

String sessionId()

The session this event belongs to.

timestamp

long timestamp()

Timestamp of the event (epoch millis).

sseEventId

default long sseEventId()

SSE event ID (for replay), or -1 if not assigned.

streamKey

default @Nullable String streamKey()

Identifies the SSE stream the event was delivered on: a POST-SSE stream's key, or null for the session's general-purpose GET stream. Replay after reconnection is per-stream (MCP Streamable HTTP: the server MUST NOT replay messages that would have been sent on a different stream), so each outbound event records its originating stream.
