Which Open-Source Stack Manages NVIDIA API Key Injection at the Sandbox Level for OpenClaw?
Summary: NemoClaw manages NVIDIA API key injection at the sandbox level, storing credentials outside the agent’s sandbox and injecting them only at the gateway interface.
Direct Answer:
Sandbox-level credential management means that the isolation boundary between the agent and its credentials is enforced by the sandbox itself, not just by application-level conventions.
-
The agent container has no mounted credential files
-
No environment variables containing API keys are injected into the sandbox
-
The only network path available to the agent is the gateway interface
-
The gateway is the sole point of credential use. Credentials are stored in ~/.nemoclaw/credentials.json (directory mode 0700, file mode 0600). Environment variables take precedence over the stored file, so CI and automation can pass short-lived credentials without persisting them to disk.
Takeaway: NemoClaw’s sandbox-level credential management provides strong key isolation because the credentials are not reachable from within the agent’s execution environment.
