Bird now supports MCP Events on its hosted MCP server at mcp.bird.com. A connected client, such as ChatGPT, can subscribe to workspace events and receive each one as it happens. Agents no longer need to poll for new mail.
Subscriptions cover new mail in a mailbox, inbound SMS, WhatsApp and Apple Messages, and email deliveries. Filters narrow a subscription to one mailbox, conversation, number or broadcast.
Each event reaches the client's callback as a webhook signed with the client's own key. A subscription lasts up to a day, so the client must renew it. Every subscription appears in the dashboard's webhook list with its client, event and filters. Admins can delete it there.
Bird has published an MCP Events guide.
