Implementation Reference
- openwrt_ssh_mcp/tools.py:158-198 (handler)The main handler function that executes the DHCP leases listing. It tries two possible lease file locations (/tmp/dhcp.leases and /var/dhcp.leases), parses the output, and returns a structured list of leases with timestamp, MAC, IP, hostname, and client_id for each device.
