閱讀 https://sourceweft.com/mcp/io.usefulapi%2Fwefact/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。

}Use your WeFact account from Claude, Cursor, or any MCP client. It reads customers, invoices, products and subscriptions, and it changes nothing. Hosted, no local install: connect with your own credentials.
Live endpoint: https://wefact.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://wefact.usefulapi.io/mcp.claude mcp add --transport http wefact https://wefact.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. 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 WeFact credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/wefact/
On first connect you provide your WeFact API key (Settings → API; the API must be switched on there). 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.
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with wefact_upgrade (it returns a Stripe Checkout link). Cancel any time with wefact_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running wefact_upgrade before then undoes the cancel. Or write to [email protected].
