Connects to eBay to price secondhand items using real sold listings. Shows price ranges, recent sales data, list prices for different selling speeds, seller net after fees, and whether a purchase price is worth reselling. Works with photos or item descriptions.

Example request: "I found a vintage camera at a thrift store for $15 - what would it sell for on eBay and would I make money?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Underpriced AI to help me. It is a free service with an MCP server at https://underpricedai.com/api/mcp/directory. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

- get_scan_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
- list_on_ebay: 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
