Vercel AI Updates: August 28, 2026

1. Chat SDK Can Now Run Claude Managed Agents

Vercel. Vercel’s Chat SDK can now run Claude Managed Agents, handling the agent loop on the server so applications receive token-by-token streaming and a live activity feed of tool calls and model requests. Session storage is managed by the Managed Agents service, removing the need to run a database, and the same agent can be deployed across Slack, Teams, Discord, and more than 30 other messaging platforms. Vercel provides a one-click deployment for a Slack research agent along with template source code. Source

2. AI SDK Harness Layer Adds Cursor Support

Vercel. The AI SDK harness layer added an official adapter for Cursor, letting applications run Cursor through the same HarnessAgent interface already used for Claude Code, Cline, Codex, and other coding agents. The adapter connects over the Agent Client Protocol, so developers can swap between coding agents without changing their application code. Source
