netbox-integration

netbox-integration is a cursor rule for Cursor from netboxlabs/netbox-best-practices. It costs 0 tokens per session (1,200 once invoked), scanned A, original, Apache-2.0.

Rules for connecting software to NetBox, a system for documenting network equipment, locations, addresses, and related infrastructure.

In plain words
What is it for?
Use them to ingest network objects with Diode, read NetBox from Python with pynetbox, process webhooks, and maintain change records.
Why use it?
They recommend suitable methods for importing data, handling dependencies, paging through results, receiving webhooks, and tracking changes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

netbox-integration scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

NetBox Integration Best Practices

Use Diode for Simplified Ingestion (HIGH)

For data ingestion, use Diode instead of direct REST API.

Benefits:

  • Automatic dependency resolution (no need to create objects in order)
  • Reference objects by name, not ID
  • Single gRPC call for batch operations
  • Built-in error handling
from netboxlabs.diode.sdk import DiodeClient
from netboxlabs.diode.sdk.ingester import Device, Entity

with DiodeClient(
    target="https://<your-diode-host>:443/diode",
    app_name="network-discovery",
    app_version="1.0.0",
) as client:
    device = Device(
        name="switch-nyc-01",
        device_type="Cisco Catalyst 9300",  # By name!
        manufacturer="Cisco",                # Auto-created if missing
        site="NYC-DC1",                      # Auto-created if missing
        role="Access Switch",
        status="active",
    )
    response = client.ingest([Entity(device=device)])

Use DiodeDryRunClient to test ingestion without sending to server.

Use pynetbox for Python Integrations (HIGH)

import pynetbox

nb = pynetbox.api("https://netbox.example.com", token=TOKEN)

# Automatic pagination
all_devices = nb.dcim.devices.all()

# Filtering
active_devices = nb.dcim.devices.filter(status="active", site="nyc")

# Create
new_device = nb.dcim.devices.create(name="switch-01", ...)

# Update
device = nb.dcim.devices.get(name="switch-01")
device.status = "active"
device.save()

Webhook Configuration

Configure webhooks for event-driven integrations:

# Webhook payload structure
{
    "event": "created",
    "timestamp": "2024-01-15T10:30:00Z",
    "model": "dcim.device",
    "username": "admin",
    "request_id": "abc123",
    "data": { ... },       # Current state
    "snapshots": {
        "prechange": {},   # State before change
        "postchange": {}   # State after change
    }
}

Best practices:

  • Use HTTPS endpoints
  • Verify webhook signatures
  • Process asynchronously (queue and acknowledge quickly)
  • Handle idempotency (webhooks may be retried)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

netbox-integration is a cursor rule published in the GitHub repository netboxlabs/netbox-best-practices (29 stars, last pushed 6mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,200 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
