Anthropic opens private beta of self-hosted Claude Managed Agents

Anthropic released self-hosted Claude Managed Agents in private beta, letting developers run the full agent service, including harness, sandboxes, credentials and session history, in their own cloud or on-premise environment. Model requests can go to Anthropic directly, to Amazon Bedrock, Google's Agent Platform or Microsoft Foundry, or through the customer's own gateway, and session history stays in the customer's database. The company says the design keeps the agent loop and vault secrets outside the sandbox, supports allowlists of permitted hosts, and exports a full record of each session over OpenTelemetry.
