# How to configure NTP client/server in Ubuntu 20
Source: https://toxigon.com/ubuntu-20-04-ntp-server

## Install NTP application

Install ntp application use apt:

```
$ sudo apt install ntp
```

This will install the NTP daemon (ntpd) and all its dependencies. 
You can check the status of the service with: 

```
$ sudo systemctl status ntp 
```

You should see output similar to this:

```
● ntp.service - Network Time Service Loaded: loaded (/lib/systemd/system/ntp.service;

import java.util.Scanner;

public class ReadSalesData {
    private String arrID[] = new String[100];
    private String arrTitle[] = new String[100];
    private String arrAuthor[] = new String[100];
    private double arrPrice[] = new double[100];
    
    private int size;
    
    public void readData(String filename){
        try{
            FileReader fr = new FileReader(filename);

    private int arrRainfall[] = new int[50];
    
    private int n;
    
    public void ReadData(String filename){
        try{

            Scanner inFile = new Scanner(fr);

# 作成手順

エディタはCursor、パッケージ管理はuvを使う想定で進める。  

## 1. プロジェクトの初期化

以下のコマンドを実行する。  

```
$ uvx create-mcp-server --path . --name mcp-server --description mcp-server --version 0.1.0 --no-claudeapp
```

## 2. 依存関係のインストール

以下のコマンドを実行する。  

```
$ uv sync --dev --all-extras
```

## 4. MCPサーバーの設定を追加

プロジェクトディレクトリの `.cursor/mcp.json` に以下のように記述する

```
{
  "mcpServers": {
    "mcp-server": {
      "command": "uv",
      "args": [
        "--directory",
        "C:\\Users\\[ユーザー]\

# 作成手順

エディタはCursor、パッケージ管理はbunを使う想定で進める。  

## 1. プロジェクトの初期化

以下のコマンドを実行する。  

```
$ bun init -y
```

## 2. 必要なツールのインストール

以下のコマンドを実行する。  

```
$ bun add @modelcontextprotocol/sdk
```

## 3. MCPサーバーの処理を作成

`index.ts` に以下のコードを記述する。  

```
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';
import { z } from "zod";

const config = {
  server: {
    name: "simple-mcp-se

# Windows

## Claude Desktop

### 1. MCPサーバーの設定を追加

`C:\Users\[ユーザー]\AppData\Roaming\Claude\claude_desktop_config.json` に以下のように記述する

```
{
  "mcpServers": {
    "sequential-thinking": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-sequential-thinking"
      ]
    }
  }
}
```

### 2. Claude Desktop を再起動する

Claude Desktop を再起動する。  
ウィンドウを閉じただけでは裏で常駐アプリが動いているので終了されないため注意する。  

### 3. 起動状態を確認する
