We’ve launched self-hosted Claude Managed Agents

Anthropic launched self-hosted Claude Managed Agents, so you can run the whole Managed Agents service on your own infrastructure instead of only the sandboxes.

Agents, sessions, and session history are stored on your side. The server sends model requests to the provider you choose, which is Anthropic by default.

Access is by request. You'll need to contact your Anthropic account team.

Self-hosted sandboxes are a separate, narrower option. They move only tool execution, files, and network egress onto your infrastructure while Anthropic keeps running the agent. A worker process you run, such as one started with the ant CLI, claims sessions from a queue and runs the agent's tool calls locally.
