Claude Agents Now Run Inside Your Own Infrastructure

Anthropic has launched two major features for Claude Managed Agents: self-hosted sandboxes and MCP tunnels. Self-hosted sandboxes let enterprises run agent tool execution on their own infrastructure or through providers like Cloudflare, Daytona, Modal, or Vercel, keeping sensitive data within their security perimeter. MCP tunnels are also now available, connecting Claude agents to private internal services like databases and APIs without exposing them to the public internet. Self-hosted sandboxes are in public beta, while MCP tunnels are in research preview with access available on request.
