  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

  id: "google_calendar-upcoming-event-alert-polling",

```bash
curl -X POST https://api.pipedream.com/v1/connect/{project_id}/triggers/deploy \

  -H "X-PD-Environment: production" \
  -H "Authorization: Bearer {access_token}" \

      "google_calendar": { "authProvisionId": "apn_xxxxxxx" },

    }
  }'
```

**MCP**

MCP servers expose Google Calendar actions as on-demand tools.

New Upcoming Event Alert (Polling) 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.

## Event delivery

Every event is sent to the HTTP endpoint you choose when you deploy the source. Or: no webhook required — your app or agent can fetch recent events from the [trigger events API](https://pipedream.com/docs/connect/api-reference/list-trigger-events.md) instead.
