閱讀 https://sourceweft.com/mcp/io.usefulapi%2Fipapi-is/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。把它新增到你客戶端的 mcpServers 設定中。

Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your ipapi.is credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/ipapi-is/
On first connect you provide your ipapi.is API key (copy it from your ipapi.is dashboard). The server validates it and stores it per user. No keys go in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.

Cancel any time with ipapi_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running ipapi_upgrade before then undoes the cancel.
