Implementation Reference
- index.ts:109-130 (registration)Registers the get_server_status tool with MCP server, including description, input schema (optional host), and inline handler for local server status.
server.tool( "get_server_status", "获取服务器的CPU、内存和运行状态", { host: z.string().optional().describe("远程服务器地址或SSH配置中的主机名") }, async () => { return { content: [{ type: 'text', text: JSON.stringify({ cpuCount: os.cpus().length, cpuRel: getLocalCpuUsage(), memory: os.freemem(), memoryUsage: ((1 - os.freemem() / os.totalmem()) * 100).toFixed(2) + '', uptime: os.uptime(), type: 'local' }, null, 2) }] }; } ); - index.ts:115-129 (handler)Handler function that computes local server status: CPU count and relative usage (using getLocalCpuUsage helper), free memory, memory usage percentage, uptime, and type 'local', formatted as JSON in text content.
async () => { return { content: [{ type: 'text', text: JSON.stringify({ cpuCount: os.cpus().length, cpuRel: getLocalCpuUsage(), memory: os.freemem(), memoryUsage: ((1 - os.freemem() / os.totalmem()) * 100).toFixed(2) + '', uptime: os.uptime(), type: 'local' }, null, 2) }] }; } - index.ts:112-114 (schema)Input schema for the tool: optional 'host' string parameter described as remote server address or SSH config hostname.
{ host: z.string().optional().describe("远程服务器地址或SSH配置中的主机名") }, - index.ts:86-98 (helper)Helper function to calculate local CPU usage percentage (idle time averaged across all CPUs). Called by the handler.
export function getLocalCpuUsage() { const cpus = os.cpus(); let totalIdle = 0, totalTick = 0; cpus.forEach((cpu) => { for (let type in cpu.times) { totalTick += cpu.times[type as keyof typeof cpu.times]; } totalIdle += cpu.times.idle; }); const idle = totalIdle / cpus.length; const total = totalTick / cpus.length; return 1 - idle / total; }
