Live from Code with Claude London: we're launching self-hosted sandboxes (public beta) and MCP tunnels (research preview) in Claude Managed Agents. Run agents inside your own perimeter, with your security controls applied by default.
Many users praised Claude's self-hosted sandboxes and integrations like Cloudflare for enabling secure enterprise agent execution with their own controls, while some raised concerns about management burdens, trust, and new cost risks.
Modal is proud to now support @claudeai Managed Agents with Modal Sandboxes.

We're partnering with an up-and-coming startup called @AnthropicAI for this. I'm bullish – I think they could be big one day!

Match made in heaven @daytonaio & @claudeai
Try self-hosted sandboxes today on the Claude Platform, and request access to MCP tunnels: http://claude.com/blog/claude-managed-agents-updates
With MCP tunnels, your agents reach MCP servers inside your private network without exposing them to the public internet.
With self-hosted sandboxes, you can run agents in any environment you control: your own infrastructure, or managed providers like Cloudflare, Daytona, Modal, or Vercel.

what better way to get the word out for the @claudeai x @modal collab than to pay @andonlabs' Claude radio station @andon_thinking to make and air an advertisement?

Managed Agents splits the agent loop from the sandbox. @anthropic runs the loop, manages session state, handles recovery. Modal gives you the production cloud infrastructure to do this at scale, with:
– Fast startup, even on heavy custom images – Scale to 100,000+ concurrent sandboxes – Volumes, snapshots, secure networking, and the rest of Modal composable in – Access to expanded CPU and GPU resources when you need it

To best support its merchants, @DoorDash is building an intelligence system with a suite of AI agents. From @andyfang:
@claudeai It’s 4:30 am I literally just wake up!
@Cloudflare Fast, isolated execution at global scale, solved.
The record of what those agents did still needs somewhere durable and verifiable to live.
That's the next layer.
@claudeai You guys are putting out truly incredible work but I’m feel really bumbed out as a local small dev. The affordability is inching away from us normal folks each day.
Self-hosted sandboxes + MCP tunnels? 🔥💪🏿
This is the exact unlock we’ve been waiting for on real multi-agent setups. No more duct-taping relays or praying data doesn’t leak run the whole squad inside your own perimeter with full security controls. Agents coordinating cleanly, humans watching the group chat, everything locked down.
Claude just made serious agent building feel production-ready instead of weekend-hack vibes. Already sketching how this slots into my next TG crew. Locked in. Let’s goooo 🔥👏🏽

@claudeai Bro please stop please you yall moving too fast 🙏🙏🙏🙏
