Reconnect an MCP event stream without losing your place
An event stream is not a permanent connection. A client needs an explicit reconnect policy and a durable position so temporary disconnects do not turn into silent gaps.
Save progress after consumption
Persist the cursor associated with events your application has actually consumed. If you advance the cursor before processing and then crash, the next connection may skip unfinished work. If you process first and crash before saving, an event can replay. Stable event IDs and idempotent handling address that second case. A cursor belongs to its particular subscription scope.

What to verify
Baleybots push requests have a documented sixty-second duration limit and send a termination notification at that limit. The application owns reconnection. Polling responses expose hasMore and nextPollMs; drain available batches before waiting. A null cursor starts from now rather than fetching history. Test disconnects, authorization loss, and truncation separately, since blindly reconnecting cannot repair every kind of missing history.
