Opt-in per server (``mcp_servers..events: true``): the SDK drops the server's ``events`` capability while parsing, so it cannot gate these tools the way ``resources``/``prompts`` do. Each subscription is a dynamic webhook route (``webhook_subscriptions.json``) with an ``mcp_event`` block (server, event name, arguments); its grant and replay cursor live in ``mcp_event_subscriptions.json``. The gateway's webhook adapter receives the deliveries (``gateway/platforms/webhook_mcp_events.py``) and the server task keeps every route's subscription alive with :func:`run_refresh_loop`. Delivery modes ``poll`` and ``push`` are not implemented.
