List devices currently holding a DHCP lease: ip, mac, name, remaining lease time (live, read-only). Use this to find a device's IP/MAC before pin_device or rename_device. For fixed reservations (including offline devices) use list_static_leases instead.

List static DHCP reservations (MAC → fixed IP) from the router's running-config (read-only). Use this to check which IPs are already reserved before set_static_lease/pin_device, or to find the MAC to pass to remove_static_lease. Includes offline devices; for currently connected devices use list_devices.

Reserve a fixed IP for a MAC address (static DHCP lease) and save the router config. Use when you already know the MAC (e.g. a device that is offline); for a connected device prefer pin_device, which looks up the MAC for you and checks for IP conflicts. This tool does NOT check conflicts — call find_free_ip or list_static_leases first. Re-running with the same values is harmless. The optional name is only the dhcp-host label; to change the display name in the web UI use rename_device. Takes effect when the device next renews its lease (reconnect it to apply immediately).

Turn a connected device's current IP into a static reservation in one step (no need to know the MAC), then save the config. Preferred way to give a device a fixed IP; use set_static_lease only for devices that are offline (not in list_devices). A name fragment must match exactly one device; an address-like identifier must be the full IP or MAC and never matches names ("66" won't hit "Room-66-Cam"). Passing ip moves the device there at its next lease renewal — get a candidate from find_free_ip. Refuses (changes nothing) if the target IP is active on or reserved to another device. Examples: pin_device("192.168.1.66") · pin_device("PS5", "192.168.1.154")

Give a device a persistent DISPLAY name on the router (Keenetic 'known host' entry = the device name in the web UI). identifier: the device's IP, MAC, or current name fragment (looked up in the active lease table). name: the new display name (spaces allowed; double quotes and non-printable characters are stripped). NOTE: set_static_lease / pin_device do NOT change the DISPLAY name — the display name is set ONLY by this tool. Examples: rename_device("192.168.1.66", "Pi5 Media") · rename_device("PS5", "PlayStation 5 Living Room")

Suggest up to 5 unused IPs on the LAN for a new static reservation (read-only; changes nothing). Use before set_static_lease or pin_device(ip=...) to avoid conflicts. Excludes active leases, existing static reservations, the gateway and broadcast. start/end are last octets (e.g. 100 and 149 → 192.168.1.100-149); pick a range outside the router's dynamic DHCP pool. start > end is accepted and swapped.

Delete the static DHCP reservation for a MAC and save the router config. Irreversible (re-create it with set_static_lease). The device stays online but may get a different dynamic IP at its next lease renewal. Use list_static_leases to find the exact MAC first. To move a device to another IP, call set_static_lease/pin_device directly instead of removing first.

Report internet (WAN) connectivity and router health: per-uplink connected/link state and WAN IP, plus router uptime, CPU load and memory. Read-only; queries the router live on every call (no caching). Use to diagnose "is the internet down?" or check the public IP; not for LAN devices (use list_devices).

List port-forwarding / static NAT rules as raw 'ip static' lines from the running-config (read-only). Use to see which ports are exposed to the internet and to which LAN host. This server cannot add or remove port forwards; change them in the router's web UI.

Reboot the router. All devices lose internet for ~1-2 minutes and this MCP server cannot reach the router until it is back. Use only as a last resort (e.g. WAN stuck down per wan_status); config and lease changes are already saved and never need a reboot. Call once with confirm=false to preview, then confirm=true to run.
