import { Client } from '@modelcontextprotocol/sdk/client/index.js';
import { StdioClientTransport } from '@modelcontextprotocol/sdk/client/stdio.js';
import { spawn } from 'child_process';

export async function createTestClient(serverCmd: string, args: string[]) {
  const proc = spawn(serverCmd, args, { stdio: ['pipe', 'pipe', 'inherit'] });
  const transport = new StdioClientTransport({ reader: proc.stdout!, writer: proc.stdin! });
