Solving:

All plugin types - http://codingtrabla.blogspot.com/2015/02/moodle-all-plugin-extention-modules.html

Let's create admin tool "mytool".

When done plugin folder should be copied to folder
.../moodle/admin/tool/   folder e.g.
.../moodle/admin/tool/mytool/

1. Create Plugin Folder structure and files

/mytool/
/mytool/version.php
/mytool/settings.php
/mytool/index.php
/mytool/lang/en/tool_mytool.php

2. /mytool/version.php

<?php

/**

 *
 * @package    tool_mytool
 * @copyright  2015  Samurai Kit
 * @license    http://www.gnu.org/copyleft/gpl.html GNU GPL v3 or later
 */

defined('MOODLE_INTERNAL') || die();

$plugin->version   = 2015010100;
$plugin->requires  = 2011120500; // Moodle 2.2.0+
$plugin->cron      = 0; // No cron jobs to run here
$plugin->component = 'tool_mytool';
$plugin->release   = '1.0 (Build: 2015010100) Trololo :) ';
$plugin->dependencies = array(); // No dependencies

3. /mytool/settings.php

<?php

/**
 * Add the admin menu link under Site Admin > Server > My Tool
 *
 * @package tool_mytool
 * @copyright  2015  Samurai Kit
 * @license   http://www.gnu.org/copyleft/gpl.html GNU GPL v3 or later
 */

defined('MOODLE_INTERNAL') || die;

if ($hassiteconfig) { // needs this condition or there is error on login page
    
    $ADMIN->add('server',
                new admin_externalpage('toolmytool',
                    get_string('pluginname', 'tool_mytool'),
                    "$CFG->wwwroot/$CFG->admin/tool/mytool/index.php"
                )
    );
   
}

4. /mytool/index.php

<?php

/**

 * @package   tool_mytool

 * @copyright  2015  Samurai Kit

 * @license   http://www.gnu.org/copyleft/gpl.html GNU GPL v3 or later

 */

// Include required libary files

require_once(dirname(__FILE__) . '/../../../config.php');

require_once($CFG->libdir . '/adminlib.php');

// Include what we need

require_once($CFG->dirroot.'/vendor/autoload.php');

// Setup admin page; authorizing, etc.

admin_externalpage_setup('toolmytool');

// Put here what to display

echo 'Trololo';

?>

5. /mytool/lang/en/tool_mytool.php

<?php

/**

 * Strings for the MyTool tool

 *

 * @package   tool_mytool

 * @copyright 2015 Samurai Kit

 * @license   http://www.gnu.org/copyleft/gpl.html GNU GPL v3 or later

 */

$string['pluginname'] = 'My Tool';

$string['trololo'] = 'Tro-Lo-Lo';

6. Copy folder /mytool/
to your moodle installation
.../moodle/admin/tool/
