What is unifi-grant-device-access?

A UniFi network-access procedure for giving one device a reserved IP address and ongoing permission to reach other network zones.

Use it for a desktop, server, NAS, or other device that must consistently reach selected networks or services. It identifies the device, its MAC address, network zone, and required rules.

It avoids access rules that depend on a changing IP address and helps prevent existing zone-firewall policies from blocking the device.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.00925
Opus 5.5	$0.00017	$0.00370
Sonnet 5.5	$0.00008	$0.00185

Security

Grade A, and why

unifi-grant-device-access scanned grade A with 0 findings 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Step 0 — Version check (always first)

Fetch get_sysinfo and note the Network application version. The controller facts in this skill were verified on Network 10.x / UniFi OS 5.x; on older versions expect differences (e.g., legacy stat/alarm exists, band steering uses an older flag). Adapt claims to the version you see.

UniFi Grant Device Access

Guarantee a specific device (e.g., a desktop, server, or NAS) can always reach everything on the network: DHCP reservation + zone-based firewall allow rules, scoped to that device's MACs.

Context (read first)

Require UNIFI_MODE=local. Resolve the device:
- If given an IP/name, find it via list_all_clients (has MACs) and get_client_details.
- If not found in known clients, ask the user to connect it once, or accept a MAC address directly.
Map zones: get_firewall_policies — note each policy's source/destination zone_id. Identify:
- The zone containing the device's current network.
- Which destination zones are already covered by existing rules for these MACs.

Controller facts

Zone firewall policies are per src-zone→dst-zone pairs; there is no "any zone" target. One rule per pair is required.
Deriving the source zone: the controller does not expose zone names or a networks→zones mapping. Find it by locating an existing custom policy scoped to known devices on the same network (source.client_macs of rules like "Allow to X ALL") and copying its source.zone_id. Do not guess by elimination — gateway-like zones allow-all everywhere and look similar to home zones in policy dumps.
The controller auto-creates "(Return)" companion policies for custom rules.
Some zone pairs are rejected at creation ("traffic not allowed") — typically ISP-managed IPTV and WAN pairs. Surface the verbatim error and skip that pair; it is usually intentional (nothing to access there anyway).
Do not create rules targeting the EXTERNAL/WAN zone — internet access is governed by the home zone's general policy, and bypassing it undermines forced-internal-DNS designs.
DHCP reservation = use_fixedip:true + fixed_ip on the client record.
