Vercel's Chat SDK now runs Claude Managed Agents: a few lines of code, 30-plus apps
Anthropic runs the agent loop server-side; Vercel supplies the chat interface. Moving the same handler from Slack to WhatsApp takes a few line changes, and there is no separate database to run.
Vercel has announced that Chat SDK, its chat interface library, can now run Anthropic's Claude Managed Agents. The division of labour is clear: Anthropic runs the agent loop server-side, Vercel provides the interface and the deployment.
What stays on Anthropic's side is the model, the tools, session state and sandboxed web research. A developer does not have to stand any of that up on their own infrastructure.
What Vercel adds is a single type-safe handler. Changing a few lines in that handler carries the agent to Slack, Teams, Discord, WhatsApp and more than 30 other platforms; an adapter takes over instead of a separate integration per platform.
Three details matter in practice. Replies arrive token by token over a single streamed response, so they render as the model writes. Tool calls and model requests are available as a live activity feed while the turn runs, making it possible to surface a trace inside the chat. And there is no database to run: the Managed Agents session stores the conversation, and the sidebar, transcript and replay read from it.
The worked example is a research bot on Slack that keeps one persistent session per thread and streams briefs with sources.
Disclosure: GlobalFeed's news pipeline uses Anthropic models among others.
The announcement is in Vercel's changelog; the open-source template is on GitHub.
