SANDBOXES FOR AI AGENTS

A VM for your agents.
In one command.

Type ssh yorkhost.sh: within seconds, an Ubuntu 24.04 Linux VM is waiting, with Claude Code, Codex, OpenCode, Cursor CLI and Gemini CLI already installed. No account, no card: your SSH key is all it takes.

HOW IT WORKS

From command to preview.
No forms.

  1. 01

    Connect

    ssh yorkhost.sh

    Your SSH key is your identity. On first connect, the terminal prints the preview URL, how long the trial lasts and the link to keep the VM.

  2. 02

    Start your agent

    claude

    Claude Code, Codex, OpenCode, Cursor CLI or Gemini CLI: they are already there. Work in /home/agent, the folder that moves with you if you keep the VM.

  3. 03

    Share the preview

    https://<id>-8080.yorkhost.sh

    Whatever your agent serves on port 8080 is public over HTTPS. Other ports too: 3000, 5173, 8000…

  4. 04

    Keep it or let it go

    ssh claim@yorkhost.sh

    The trial stops after 60 minutes. You have 24 hours to keep it as a VPS-2 from your YorkHost account, otherwise the VM and its files are deleted.

PREVIEW URLS

Your agent codes.
Anyone can see it.

Every port served inside the VM gets its own HTTPS address, with no setup. Demo an app, test a webhook or open the result on your phone.

Previews go through yorkhost.sh: during the trial, the VM has no public IP.

KEEP THE VM

Like it?
Keep it as a VPS.

ssh claim@yorkhost.sh (or the link printed on connect) gives you your sandbox's token. Claim it from your YorkHost account, through your AI agent (MCP) or the API: the price is shown, you confirm and pay the invoice. The sandbox becomes a real VPS-2 and your /home/agent files are copied to it.

ALL OVER SSH

A few commands.
Nothing else to install.

ssh yorkhost.sh
Creates a sandbox, or reconnects you to yours.
ssh <id>@yorkhost.sh
Goes back to a specific sandbox.
ssh status@yorkhost.sh
Lists your sandboxes as JSON.
ssh claim@yorkhost.sh
Gives the token to keep it as a VPS-2.
ssh destroy@yorkhost.sh
Deletes it right away.
ssh -L 8080:localhost:8080 <id>@yorkhost.sh
Port forwarding. sftp works too.

FOR AGENTS

Your agents can create
their own sandboxes too.

With an API key from your YorkHost account, the client API and the MCP server let an agent create, list, keep or delete sandboxes, then order and pay for services.
