Vercel MCP now publishes events, so agents can subscribe to Vercel platform events like deployment.succeeded and deployment.error and react to what happens on your projects instead of polling for changes.
An agent subscribes once, filtering by team, project, and environment, and Vercel MCP manages an ordinary expiring Vercel webhook behind it. Refreshes extend the subscription, an abandoned one expires on its own, and event webhooks run on their own per-team limit, so they don't count against your 40 account webhooks.
Deliveries are signed Standard Webhooks with Vercel's native webhook payload in data.
See the AI SDK cookbook Receive MCP Webhook Events to implement the receiving side.
