Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。
把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。
閱讀 https://sourceweft.com/mcp/io.usefulapi%2Finvoice-ninja/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 Invoice Ninja from Claude, Cursor, or any MCP client — read and create clients, invoices, quotes, expenses, tasks and projects, convert quotes, and email invoices. Hosted, no local install: connect with your own Invoice Ninja credentials.
Live endpoint: https://invoice-ninja.usefulapi.io/mcp · Homepage: https://usefulapi.io/invoice-ninja
https://invoice-ninja.usefulapi.io/mcp.claude mcp add --transport http invoice-ninja https://invoice-ninja.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 Invoice Ninja credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/invoice-ninja/
On first connect you'll provide your Invoice Ninja API token (Settings → Account Management → Integrations → API tokens), plus your instance URL if you self-host. They're validated, stored per-user, and scoped to you — no keys 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.
Each paid plan covers this server only. Ask your AI to run invoiceninja_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with invoiceninja_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with invoiceninja_upgrade before then undoes the cancel. Or write to [email protected].
