Network Policies#

NemoClaw runs with a deny-by-default network policy. The sandbox can only reach endpoints that are explicitly allowed. Any request to an unlisted destination is intercepted by OpenShell, and the operator is prompted to approve or deny it in real time through the TUI.

Baseline Policy#

The baseline policy is defined in nemoclaw-blueprint/policies/openclaw-sandbox.yaml.

Filesystem#

Path

Access

/sandbox, /tmp, /dev/null

Read-write

/usr, /lib, /proc, /dev/urandom, /app, /etc, /var/log

Read-only

The sandbox process runs as a dedicated sandbox user and group. Landlock LSM enforcement applies on a best-effort basis.

Network Policies#

The following endpoint groups are allowed by default:

Policy

Endpoints

Binaries

Rules

claude_code

api.anthropic.com:443, statsig.anthropic.com:443, sentry.io:443

/usr/local/bin/claude

POST to inference paths on api.anthropic.com, POST on statsig.anthropic.com, GET only on sentry.io

nvidia

integrate.api.nvidia.com:443, inference-api.nvidia.com:443

/usr/local/bin/claude, /usr/local/bin/openclaw

POST to inference and embedding paths, GET to model listings

clawhub

clawhub.ai:443

/usr/local/bin/openclaw, /usr/local/bin/node

GET, POST

openclaw_api

openclaw.ai:443

/usr/local/bin/openclaw, /usr/local/bin/node

GET, POST

openclaw_docs

docs.openclaw.ai:443

/usr/local/bin/openclaw

GET only

npm_registry

registry.npmjs.org:443

/usr/local/bin/openclaw only (openclaw plugins install)

GET only

All endpoints use TLS termination and are enforced at port 443.

Note

GitHub access (github.com, api.github.com) is not included in the baseline policy. Apply the github preset during onboarding if your agent needs GitHub access. See Customize the Network Policy.

Policy Tiers#

During onboarding, the wizard prompts for a policy tier that determines the default set of presets applied on top of the baseline policy. The baseline policy is always applied regardless of the selected tier.

Tier

Presets included

Description

Restricted

None

Base sandbox only. No third-party network access beyond inference and core agent tooling.

Balanced (default)

npm, pypi, huggingface, brew, brave

Full dev tooling and web search. No messaging platform access.

Open

npm, pypi, huggingface, brew, brave, slack, discord, telegram, jira, outlook

Broad access across third-party services including messaging and productivity.

After selecting a tier, a combined preset and access-mode screen lets you include or exclude individual presets and toggle each between read (GET only) and read-write (GET + POST/PUT/PATCH) access. Tier-default presets are pre-selected; additional presets can be added from the full list.

Tier definitions are stored in nemoclaw-blueprint/policies/tiers.yaml.

In non-interactive mode, set the tier with NEMOCLAW_POLICY_TIER:

$ NEMOCLAW_POLICY_TIER=open nemoclaw onboard --non-interactive --yes-i-accept-third-party-software

If the value does not match a known tier, onboarding exits with an error listing the valid options.

Inference#

The baseline policy allows only the local inference route. External inference providers are reached through the OpenShell gateway, not by direct sandbox egress.

Operator Approval Flow#

When the agent attempts to reach an endpoint not listed in the policy, OpenShell intercepts the request and presents it in the TUI for operator review:

  1. The agent makes a network request to an unlisted host.

  2. OpenShell blocks the connection and logs the attempt.

  3. The TUI command openshell term displays the blocked request with host, port, and requesting binary.

  4. The operator approves or denies the request.

  5. If approved, the endpoint is added to the running policy for the session.

To try this, run the walkthrough:

$ ./scripts/walkthrough.sh

This opens a split tmux session with the TUI on the left and the agent on the right.

Modifying the Policy#

Static Changes#

Edit nemoclaw-blueprint/policies/openclaw-sandbox.yaml and re-run the onboard wizard:

$ nemoclaw onboard

Dynamic Changes#

Apply policy updates to a running sandbox without restarting:

$ openshell policy set --policy <policy-file> <sandbox-name>
