NVIDIA NemoClaw
Skill by ara.so — Daily 2026 Skills collection.
NVIDIA NemoClaw is an open-source TypeScript CLI plugin that simplifies running OpenClaw always-on AI assistants securely. It installs and orchestrates the NVIDIA OpenShell runtime, creates policy-enforced sandboxes, and routes all inference through NVIDIA cloud (Nemotron models). Network egress, filesystem access, syscalls, and model API calls are all governed by declarative policy.
Status: Alpha — interfaces and APIs may change without notice.
Installation
Prerequisites
- Linux Ubuntu 22.04 LTS or later
- Node.js 20+ and npm 10+ (Node.js 22 recommended)
- Docker installed and running
- NVIDIA OpenShell installed
One-Line Installer
curl -fsSL https://nvidia.com/nemoclaw.sh | bash
This installs Node.js (if absent), runs the guided onboard wizard, creates a sandbox, configures inference, and applies security policies.
Manual Install (from source)
git clone https://github.com/NVIDIA/NemoClaw.git
cd NemoClaw
npm install
npm run build
npm link # makes `nemoclaw` available globally
Environment Variables
# Required: NVIDIA cloud API key for Nemotron inference
export NVIDIA_API_KEY="nvapi-xxxxxxxxxxxx"
# Optional: override default model
export NEMOCLAW_MODEL="nvidia/nemotron-3-super-120b-a12b"
# Optional: custom sandbox data directory
export NEMOCLAW_SANDBOX_DIR="/var/nemoclaw/sandboxes"

Quick Start
1. Onboard a New Agent
nemoclaw onboard
The interactive wizard prompts for:
- Sandbox name (e.g.
my-assistant) - NVIDIA API key (
$NVIDIA_API_KEY) - Inference model selection
- Network and filesystem policy configuration
Expected output on success:
──────────────────────────────────────────────────
Sandbox my-assistant (Landlock + seccomp + netns)
Model nvidia/nemotron-3-super-120b-a12b (NVIDIA Cloud API)
──────────────────────────────────────────────────
Run: nemoclaw my-assistant connect
Status: nemoclaw my-assistant status
Logs: nemoclaw my-assistant logs --follow
──────────────────────────────────────────────────

2. Connect to the Sandbox
nemoclaw my-assistant connect
3. Chat with the Agent (inside sandbox)
TUI (interactive chat):
sandbox@my-assistant:~$ openclaw tui
CLI (single message):
sandbox@my-assistant:~$ openclaw agent --agent main --local -m "hello" --session-id test

Architecture
NemoClaw orchestrates four components:
| Component | Role |
|---|---|
| Plugin | TypeScript CLI: launch, connect, status, logs |
| Blueprint | Versioned Python artifact: sandbox creation, policy, inference setup |
| Sandbox | Isolated OpenShell container running OpenClaw with policy-enforced egress/filesystem |
| Inference | NVIDIA cloud model calls routed through OpenShell gateway |
Blueprint lifecycle:
- Resolve artifact
- Verify digest
- Plan resources
- Apply through OpenShell CLI
TypeScript Plugin Usage
NemoClaw exposes a programmatic TypeScript API for building custom integrations.
Import and Initialize
import { NemoClawClient } from '@nvidia/nemoclaw';
const client = new NemoClawClient({
apiKey: process.env.NVIDIA_API_KEY!,
model: process.env.NEMOCLAW_MODEL ?? 'nvidia/nemotron-3-super-120b-a12b',
});
Create a Sandbox Programmatically
import { NemoClawClient, SandboxConfig } from '@nvidia/nemoclaw';
async function createSandbox() {
const client = new NemoClawClient({
apiKey: process.env.NVIDIA_API_KEY!,
});
const config: SandboxConfig = {
name: 'my-assistant',
model: 'nvidia/nemotron-3-super-120b-a12b',
policy: {
network: {
allowedEgressHosts: ['build.nvidia.com'],
blockUnlisted: true,
},
filesystem: {
allowedPaths: ['/sandbox', '/tmp'],
readOnly: false,
},
},
};
const sandbox = await client.sandbox.create(config);
console.log(`Sandbox created: ${sandbox.id}`);
return sandbox;
}
Connect and Send a Message
import { NemoClawClient } from '@nvidia/nemoclaw';
async function chatWithAgent(sandboxName: string, message: string) {
const client = new NemoClawClient({
apiKey: process.env.NVIDIA_API_KEY!,
});
const sandbox = await client.sandbox.get(sandboxName);
const session = await sandbox.connect();
const response = await session.agent.send({
agentId: 'main',
message,
sessionId: `session-${Date.now()}`,
});
console.log('Agent response:', response.content);
await session.disconnect();
}
chatWithAgent('my-assistant', 'Summarize the latest NVIDIA earnings report.');
Check Sandbox Status
import { NemoClawClient } from '@nvidia/nemoclaw';
async function checkStatus(sandboxName: string) {
const client = new NemoClawClient({
apiKey: process.env.NVIDIA_API_KEY!,
});
const status = await client.sandbox.status(sandboxName);
console.log({
sandbox: status.name,
healthy: status.healthy,
blueprint: status.blueprintState,
inference: status.inferenceProvider,
policyVersion: status.policyVersion,
});
}
Stream Logs
import { NemoClawClient } from '@nvidia/nemoclaw';
async function streamLogs(sandboxName: string) {
const client = new NemoClawClient({
apiKey: process.env.NVIDIA_API_KEY!,
});
const logStream = client.sandbox.logs(sandboxName, { follow: true });
for await (const entry of logStream) {
console.log(`[${entry.timestamp}] ${entry.level}: ${entry.message}`);
}
}
Apply a Network Policy Update (Hot Reload)
import { NemoClawClient, NetworkPolicy } from '@nvidia/nemoclaw';
async function updateNetworkPolicy(sandboxName: string) {
const client = new NemoClawClient({
apiKey: process.env.NVIDIA_API_KEY!,
});
// Network policies are hot-reloadable at runtime
const updatedPolicy: NetworkPolicy = {
allowedEgressHosts: [
'build.nvidia.com',
'api.github.com',
],
blockUnlisted: true,
};
await client.sandbox.updatePolicy(sandboxName, {
network: updatedPolicy,
});
console.log('Network policy updated (hot reload applied).');
}
Security / Protection Layers
| Layer | What it protects | Hot-reloadable? |
|---|---|---|
| Network | Blocks unauthorized outbound connections | ✅ Yes |
| Filesystem | Prevents reads/writes outside /sandbox and /tmp |
❌ Locked at creation |
| Process | Blocks privilege escalation and dangerous syscalls | ❌ Locked at creation |
| Inference | Reroutes model API calls to controlled backends | ✅ Yes |
When the agent attempts to reach an unlisted host, OpenShell blocks the request and surfaces it in the TUI for operator approval.
Common Patterns
Pattern: Minimal Sandbox for Development
const config: SandboxConfig = {
name: 'dev-sandbox',
model: 'nvidia/nemotron-3-super-120b-a12b',
policy: {
network: { blockUnlisted: false }, // permissive for dev
filesystem: { allowedPaths: ['/sandbox', '/tmp', '/home/dev'] },
},
};
Pattern: Production Strict Sandbox
const config: SandboxConfig = {
name: 'prod-assistant',
model: 'nvidia/nemotron-3-super-120b-a12b',
policy: {
network: {
allowedEgressHosts: ['build.nvidia.com'],
blockUnlisted: true,
},
filesystem: {
allowedPaths: ['/sandbox', '/tmp'],
readOnly: false,
},
},
};
Pattern: Deploy to Remote GPU (Brev)
nemoclaw deploy my-gpu-instance --sandbox my-assistant
await client.deploy({
instance: 'my-gpu-instance',
sandboxName: 'my-assistant',
provider: 'brev',
});
Troubleshooting
Error: Sandbox not found
Error: Sandbox 'my-assistant' not found
Fix: Check at the OpenShell layer — NemoClaw errors and OpenShell errors are separate:
openshell sandbox list
nemoclaw my-assistant status
Error: NVIDIA API key missing or invalid
Error: Inference provider authentication failed
Fix:
export NVIDIA_API_KEY="nvapi-xxxxxxxxxxxx"
nemoclaw onboard # re-run to reconfigure
Error: Docker not running
Error: Cannot connect to Docker daemon
Fix:
sudo systemctl start docker
sudo usermod -aG docker $USER # add current user to docker group
newgrp docker
Error: OpenShell not installed
Error: 'openshell' command not found
Fix: Install NVIDIA OpenShell first, then re-run the NemoClaw installer.
Agent blocked on outbound request
When you see a blocked request notification in the TUI:
openshell term # open TUI to approve/deny the request
# OR update policy to allow the host:
nemoclaw my-assistant policy update --allow-host api.example.com
