New Reaction Added (Instant) is an event source, so your application deploys it
with the Connect SDK or API and then either receives each event at a
webhook URL or retrieves events on demand with the trigger events API.MCP exposes on-demand actions. Event sources are deployed through the Connect SDK or API because they continue listening after the initial request.
