Sandboxed cloud agents trade security for secrets management, prompting rethink
Lucas Meijer's AgentsInTheCloud runs cloud agents inside sandboxes. He reports the experience is good and secure, but the agents are limited: they cannot set secrets or diagnose configuration issues, making security and usability hard to reconcile. Meanwhile, the convenience of driving his agent fleet via a Grok bot has led him to question whether his "sandbox everything" stance is too extreme.
Confirmed
- AgentsInTheCloud uses a sandboxed isolation architecture; agents cannot perform sensitive operations like setting secrets
- Meijer is migrating a project with 20 local secrets, feeling the pain of secrets management firsthand
- A community workaround—running a local coding agent that connects to the AgentsInTheCloud environment via Tailscale to handle secrets—was endorsed by Meijer
- Meijer said using a Grok bot to drive his cloud agent cluster is "incredibly convenient," making him realize his isolation boundaries may be too strict
Why it matters
- rcarmo noted there is no unified way to script setting and updating shared secrets when migrating workspaces—whether via API, MCP, or agents—a clear gap in cloud agent infrastructure
- The case illustrates a classic tension in agent cloudification: sandboxing enforces security but severs agents from sensitive configuration, while the real convenience of agent-to-agent collaboration tempts developers to loosen boundaries; the community needs standardized solutions balancing both
