Claude Managed Agents can now run in your own sandbox
Anthropic just gave Claude Managed Agents two major enterprise upgrades: self-hosted sandboxes and MCP tunnels. You can now keep tool execution, sensitive code, and data entirely inside your own infrastructure or providers like Cloudflare and Modal, while Claude only handles the agent orchestration. MCP tunnels also let agents securely call internal databases without punching holes in corporate firewalls. Self-hosted sandboxes are in public beta, while tunnels require an access request.
