 🟨 Conclusion
 This workflow redefines how we build and run tools. From scaffolding an MCP server to interacting with it using plain language, the line between prompt and program is disappearing.

+.SYNOPSIS 
+   Get my public IP Address  
+
+   .DESCRIPTION
+   Uses http://ipinfo.io/json to get the public IP Address of the machine running this script.
+   This is useful for testing and debugging purposes, especially when working with APIs that require a public IP Address.
+
+   .EXAMPLE
+    Get-PublicIPAddress
+
+    .OUTPUTS
+    Returns the public IP Address of the machine running the script.

+.Synopsis
+   Can resolve either an IP Address or a Domain Name and give you geolocation information.
+.DESCRIPTION
+   This module is using https://freegeoip.live API which is free. Yes. It's totally free. They believe that digital businesses need to get such kind of service for free. Many services are selling Geoip API as a service, but they think that it should be totally free. Feel free to their API as much as you want without any limit other than 10,000 queries per hour for one IP address. I thought this would be another good addition to add to the Powershell Gallery.
+.Parameter IP
+   This parameter is used to specify the IP Address you want to find the geolocation information
+.Parameter DomainName
+   This parameter is used to specify the Domain Name address you want to find the geolocation information
+.EXAMPLE
+   Find-Geolocation -DomainName portsmouth.co.uk

+   Find-Geolocation -IP 141.193.213.10
