## Starting kind-cluster in podman

If you use podman desktop on a mac and want to use a kind-cluster:

```sh
export KIND_EXPERIMENTAL_PROVIDER=podman
kind create cluster --name local-kind-cluster
```

## create docker-image in podman
By default, podman can only pull images from publicly available registries.
If you build a docker-image locally, it will not be available in the 
podman or kind cluster.

Therefore you need to build the docker image with podman directly, or import
it into there.

# 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;

    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
