Configuration

Variable	Required	Secret	Description
IRONCLAW_CONTROLPLANE_URL	yes	—	Base URL of your running IronClaw control-plane, e.g. http://127.0.0.1:8787. This image is a thin client with no host privilege: it delegates every sandbox_exec run to the control-plane, which owns the hardened gVisor launch. Unset means no backend and the tool fails closed.
IRONCLAW_API_TOKEN	yes	yes	Bearer token for the control-plane API (the value the control-plane was started with).
