交给智能体安装
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

Worth
Never overpay, never undersell.
Ask your AI "what's it worth?" about anything (thrift finds, collectibles, electronics, vintage) and get its resale value, used price and new price, plus links to the best place to buy or sell.
[Add to Cursor] [Install in VS Code]
What you get
- A fair price in seconds. Name it or snap a photo; get an estimate with a confidence score.
- Know if used is worth it. See new vs. used vs. resale side by side, and how much you save or can earn.
- The best place to buy or sell. Direct links to stores and marketplaces, matched to what you want to do.
Great for thrift flipping, reselling for beginners, pricing yard sale items, or deciding whether to buy used instead of new. No account, no sign-in. Prices come from live listings and are estimates, not offers.
