MTGstand-Value-Detector is a Chrome extension designed to enhance Magic the Gathering eBay auctions by displaying the current card value alongside auction prices. It seamlessly integrates with various eBay pages including search pages, seller pages, and single auction pages, ensuring that users have quick access to card values regardless of their location on the platform.

The extension scans auction titles for card names, set names, set codes, collector numbers, and special effects like "foil," "borderless," "showcase," and "extended art." By doing so, it provides users with the current card value, a link to the MTGstand single card page, and a link to the Scryfall page, offering comprehensive information to aid in decision-making.
