ChatGPT · Claude · Cursor
Ask your AI assistant what it sold for
Connect Comps once, then ask in plain words — “what do Carhartt Detroit jackets sell for on Vinted UK?” or “where does this sell for more?” — and get real sold prices, not guesses.
1. Copy the Comps address
https://swanum.com/comps/mcpWithout a key you get 5 free searches to try it. With your free Comps key you get 1,000 a month and the 7-country comparison: add it to the end, https://swanum.com/comps/mcp?key=YOUR_KEY. Your dashboard shows the address with your key already in it.
2. Add it to your assistant
- ChatGPT: Settings → Apps & Connectors → Advanced → turn on Developer mode, then create a connector, paste the address, no authentication.
- Claude: Settings → Connectors → Add custom connector, paste the address.
- Cursor, VS Code and other clients:
{"mcpServers": {"comps": {"url": "https://swanum.com/comps/mcp?key=YOUR_KEY"}}}
3. Ask
You: What did Nike Tech Fleece hoodies sell for on Vinted France?
Assistant: answers with the number of confirmed sales, the median and typical range, how fast they sold and a few example sales — and a link to every sale on Comps.
What it can do
- Sold prices in one country — sales count, median and range, time to sell, example sales.
- Compare countries — the same search across France, the UK, Germany, Spain, Italy, the Netherlands and Poland, to see where it sells for more (needs a free key).
