Was dieses MCP kann

Estimates secondhand item resale prices from eBay sold listings, calculates fees and profitability, and prepares draft eBay listings.

buy_credits
Buy scan credits
Ways to pay for Underpriced AI scans. Without a choice it lists the credit packs (5 to 250 scans, from $3; credits never expire) and, for a signed-in user, their balance. PACK_5, PACK_15 and PACK_30 can be bought here: with one it returns a Stripe Checkout link for that user. PAY_AS_YOU_GO is only for a signed-in plan subscriber whose plan scans run out (top-up scans, 25 cents each past the plan); it is listed only when the account can use it. Larger packs and monthly plans (whose unused scans carry over one month) are on the pricing page. Anonymous callers get the pricing page link.

Leave empty to see the options and the balance first.'}}}
get_scan_result
Fetch a saved scan's result
For a signed-in user: the finished result for a scan on their account, in the same shape as price_item, once the sold comps have landed in the background. Call it with the account.scanId a photo price returned when that result said comps were still loading (about 20 seconds later), or to re-read any saved scan.

get_sold_comps
Recent eBay sold comps
The most recent real eBay US sales (sold comps) for a search query (brand, model or pattern, a few specific words), with the count, median and quartiles. Use when the user wants to see what actually sold and for how much.

list_on_ebay
Prepare an eBay listing
For a signed-in user: turns a photo scan from price_item (account.scanId) into an inventory item with a draft eBay listing on their Underpriced AI account (title, list price defaulting to the market price, condition, description) and returns the link where they review and publish it in the app, plus whether eBay is connected and the connect link if not (connecting brings them back to the same item). It never publishes anything and only prepares eBay; publishing happens in the app after the user checks the listing, and until then the draft shows on the Sell tab under Not live yet.

price_item
Price an item
What a secondhand item sells for on eBay: a calibrated estimate with a range, the recent real eBay sales behind it (sold comps, linked where the source gives a link), three list prices (fast, market, patient) with the 14-day sell chance, what the seller keeps after eBay fees, and a worth-it verdict when you pass what the user would pay. Description prices are eBay US in USD. A photo price (image_url, a public https link) needs the user signed in through the connector: it runs a real scan on their account, priced in their own eBay marketplace and currency (price.currency). Without sign-in, describe the item; a description works but reads less than a photo.

worth_it
Worth buying at this cost?
What the seller keeps after eBay fees and a verdict (worth it / thin / pass) for an expected sale price and what the user would pay. Pure arithmetic in USD; use price_item first when the sale price is unknown.
