Model Context Protocol (MCP) Servers Configuration Guide

Common Server Setup

All MCP servers follow a basic configuration pattern:

import { Server } from "@modelcontextprotocol/sdk/server/index.js";

//  Remove any duplicates from an array of primitives.
const unique = [...new Set(arr)]

// Sleep in async functions. Use: await sleep(2000).
const sleep = (ms) => (new Promise(resolve => setTimeout(resolve, ms)));

// Type this in your code to break chrome debugger in that line.

1. Remove duplicates from an array of numbers/strings
Well, this is the only one not about map/reduce/filter but it’s so concise that it was hard not to put it in the list. Plus we’ll use it in a couple of examples too.
let values = [3, 1, 3, 5, 2, 4, 4, 4];
let uniqueValues = [...new Set(values)];
// uniqueValues is [3, 1, 5, 2, 4]
2. A simple search (case-sensitive)
The .filter() method creates a new array with all elements that pass the test implemented by the provided function.
let users = [
  { id: 11, name: 'Adam', age: 23, group: 'editor' },
  { id: 47, name: 'John', age: 28, group: 'admin' },
