Implementation Reference
- openwrt_ssh_mcp/tools.py:49-93 (handler)The main implementation of get_system_info() in the OpenWRTTools class. Executes multiple commands (ubus call system board, ubus call system info, cat /proc/uptime, cat /proc/loadavg) to gather comprehensive system information, parses JSON output from ubus commands, and returns a structured response with board details, system info, uptime, and load average.
