Latest update (11-09 15:13): Vercel MCP adds event subscriptions so agents get webhook alerts

Overview: Vercel says its MCP server now publishes events that agents can subscribe to, such as deployment.succeeded and deployment.error. Subscribed agents receive webhook notifications when those events fire, so they do not need to poll for changes. The announcement came from Vercel's developer account on X on November 9, 2026.
