Implementation Reference
- openwrt_ssh_mcp/tools.py:200-220 (handler)The actual handler implementation that executes 'iptables -L -n -v' to retrieve firewall rules from the OpenWRT router
@staticmethod async def get_firewall_rules() -> dict[str, Any]: """ Get firewall rules. Returns: dict: Firewall rules """ command = "iptables -L -n -v" result = await OpenWRTTools.execute_command(command) if result["success"]: return { "success": True, "rules": result["output"], } else: return { "success": False, "error": result["error"], } - openwrt_ssh_mcp/server.py:107-114 (schema)Tool schema definition registered with MCP server - defines name, description, and input validation (no parameters required)

elif name == "openwrt_get_firewall_rules": result = await OpenWRTTools.get_firewall_rules() - openwrt_ssh_mcp/tools.py:17-47 (helper)The execute_command helper method used by get_firewall_rules - validates commands via SecurityValidator and executes them via ssh_client
