MCP通信方式

js
1.stdio
2.http

node 模拟进程通信

js
process.stdout.write("Hello, World!1\n"); //标准输出，可写流 

process.js 主进程
//创建子进程
const { spawn } = require('child_process');

const child = spawn("node", ["server.js"]);
//监听子进程标准输入
child.stdout.on('data', (data) => {
  console.log(`stdout: ${data}`);
});
// 标准错误
child.stderr.on('data', (data) => {
  console.error(`stderr: ${data}`);
});
//关闭
child.on('close', (code) => {
  console.log(`child process exited with code ${code}`);
});

child.stdin.write('标准输入')


//server.js 子进程
process.stdin.setEncoding("utf8");

process.stdin.on("data", (chunk) => {
  console.log("子进程收到输入:", chunk.trim());
});
