Real eBay results through the official Browse API — keyword search, condition and price filters, and full listing details, all inside your AI conversation.
Secondhand MCP's eBay integration uses the official eBay Browse API — not scraping — so results are fast, complete, and reliable. Search by keyword with condition filters (new, like-new, good, fair), price ranges, and sort options, then pull full listing details with every photo at full resolution.
eBay search works out of the box on every plan, including free, with no keys to create. If you would rather use your own free eBay developer credentials you still can: add them on your account page and they are encrypted at rest (AES-256-GCM) and validated against the eBay API when you save them. Regional marketplaces are supported too, so you can search eBay US, UK, DE and others.
Because the AI sees structured listing data, eBay works especially well for price research: ask what something typically sells for, compare active listings against a Facebook Marketplace find, or hunt for mispriced items across categories.
eBay search is available on every tier, including free, with no setup — we cover the API access. You can still supply your own free keys from developer.ebay.com if you prefer to use your own quota.
Once connected, just talk to your AI assistant

eBay offers an official, free Browse API, and using it is more reliable than scraping. Creating an eBay developer account takes about five minutes and the free tier (5,000 calls/day) is more than enough for personal use.
On the hosted service, paste them once into your account page — they are validated against the eBay API and stored encrypted (AES-256-GCM). For the open-source local server, set them as environment variables in your MCP client config.
Yes. The regional marketplace is configurable (EBAY_US, EBAY_GB, EBAY_DE, and others) via the EBAY_MARKETPLACE_ID setting.
Very. The AI gets structured prices and conditions, so you can ask things like "what's the going rate for this?" or have it compare a local Facebook Marketplace find against current eBay listings.
No. Secondhand MCP is read-only — it searches and fetches details. Bidding and buying happen on eBay, by you.
