Anthropic enhances Claude Managed Agents with two new privacy and security features

Anthropic added MCP tunnels and self-hosted sandboxes to Claude Managed Agents to improve enterprise privacy and security.

MCP tunnels let Claude connect to private MCP servers without exposing them to the public internet.

Self-hosted sandboxes shift tool execution to customer- or partner-owned infrastructure while Anthropic keeps the agent loop.

MCP tunnels are in limited research preview, while self-hosted sandboxes are now in public beta.
