Run Cloud Agents in a sandbox

The ubuntu template has Claude Code, Codex and OpenCode installed.

Run an agentCopy Anchor Link

1. Create a sandbox from the ubuntu template. Put the keys of the agent in env.
2. Run the agent with a command, or connect over SSH and use its terminal UI.
3. Read the result in the output of the command, or in the files of the sandbox.

curl -sS --fail-with-body https://api.munito.ai/sandboxes/v1/sandboxes \
  -H "Authorization: Bearer $MUNITO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"template": "ubuntu", "timeout": 3600, "env": {"ANTHROPIC_API_KEY": "sk-ant-..."}}'

Each command and each SSH shell of the sandbox gets the variables in env.

LimitsCopy Anchor Link

• Commands and SSH shells run as root.
• A command runs for 30 minutes or less. For a longer task, use nohup or tmux.
• A persistent sandbox keeps its files and sign-ins when it pauses.

Keep your keys safeCopy Anchor Link

Each program in the sandbox can read its environment, and the agent can too. Thus:

• Use a key that you can revoke, with the smallest permissions and spend limit that the task needs.
• To give a key to one command only, put the key in the env of that command.
• Sign in to a subscription in the sandbox, over SSH. Then the sign-in does not go through the API.
• Delete the sandbox when the task is complete.
