Anthropic Just Solved the Biggest Problem for Scaling AI Agents (Self-Hosted Sandboxes)

I can now deploy my experimental Claude agents in production without losing sleep over what can go wrong

Self-hosted sandboxes are now in public beta, and MCP tunnels are in research preview.

Together, they change the architecture of how Claude agents interact with your internal systems.

If you’ve been holding off on deploying Claude agents in production because of data privacy concerns, that’s the past; now you can.

The models are good enough, and the tooling is maturing fast.

But the moment you start talking about connecting an agent to internal databases, proprietary codebases, or sensitive APIs, it gets scary!

Anthropic has updated Claude Managed Agents with two new capabilities:

Self-hosted sandboxes — run agent tool execution inside your own infrastructure or with a managed provider you choose

MCP tunnels — connect agents to internal services over an encrypted channel, no public endpoints required
