概覽

AI 產生的概覽

BillionVerify 讓 AI 助理驗證單一或批次電子郵件地址、查詢點數餘額、檢視驗證歷史與統計，並管理 webhook。

可以做什麼
逐一或每批最多 50 個驗證電子郵件地址，檢查語法、網域郵件伺服器，並可選擇透過 SMTP 檢查信箱，每次檢查消耗帳戶點數。查詢帳戶點數餘額與非同步驗證工作狀態。檢視驗證歷史及 7 天、30 天、90 天與 1 年的彙總統計。取得已完成結果的簽章下載連結或 CSV 內容。建立、列出並永久刪除用於驗證生命週期通知的 webhook 端點。檢查伺服器健康狀態。
適用情境
適合助理需要清理或驗證電子郵件清單、在寄送前確認地址能否收信，或從 BillionVerify 帳戶查看驗證用量與結果的情境。
執行需求
可使用託管遠端端點並以 OAuth 登入 BillionVerify 帳戶，或使用本機 npm 套件 billionverify-mcp，需 Node.js 18+ 及環境變數 BILLIONVERIFY_API_KEY。可選環境變數 BILLIONVERIFY_API_URL 覆寫 API 基礎位址。需要具備點數的 BillionVerify 帳戶。
安裝前請注意
驗證呼叫會消耗所連結 BillionVerify 帳戶的點數，批次執行會產生費用。自架方式需要在環境中提供 BILLIONVERIFY_API_KEY 密鑰。電子郵件地址會傳送至 BillionVerify 的 API 進行檢查。建立與刪除 webhook 會變更帳戶設定，刪除為永久操作並立即停止通知。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 BillionVerify，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

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。

交給代理程式安裝

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.github.BillionVerify%2Fbillionverify-mcp/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。

README

BillionVerify MCP Server — TypeScript

Connect any AI assistant to BillionVerify email verification via the Model Context Protocol. Built with the official MCP TypeScript SDK.

Option 1 — Hosted Server (No Installation)

Use BillionVerify's hosted MCP server. There is nothing to install and no API key to paste: you sign in with your BillionVerify account over OAuth, and the connection is tied to that account.

Server URLhttps://mcp.billionverify.com/mcp
TransportStreamable HTTP
AuthenticationOAuth 2.1 (sign in with your BillionVerify account)

The hosted server does not accept API keys (?api_key=, BV-API-KEY or Authorization: Bearer <api key> are all rejected). If you want to use an API key, use Option 2.

Detailed step-by-step guide: docs/connect-chatgpt-claude.md.

ChatGPT (web)

  1. Settings → Apps & Connectors → Advanced settings → turn on Developer mode.
  2. Settings → Apps & Connectors → Create.
  3. Name BillionVerify, MCP server URL https://mcp.billionverify.com/mcp, authentication OAuth → create.
  4. Sign in to BillionVerify in the window that opens and approve access.
  5. In a new chat, click + → Developer mode → enable BillionVerify.

Claude (claude.ai / Claude Desktop)

  1. Customize → Connectors → + → Add custom connector.
  2. Name BillionVerify, URL https://mcp.billionverify.com/mcp → Add (leave Advanced settings empty).
  3. Click Connect, sign in to BillionVerify and approve access.
  4. In a chat, click + → Connectors and make sure BillionVerify is on.

Team / Enterprise: an Owner adds the connector under Organization settings → Connectors, then each member clicks Connect.

Claude Code

bash
claude mcp add --transport http billionverify https://mcp.billionverify.com/mcp

Then run /mcp inside Claude Code, select billionverify and finish the sign-in in your browser.

Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project), then click Connect next to the server in Settings → MCP:

json
{  "mcpServers": {    "billionverify": {      "url": "https://mcp.billionverify.com/mcp"    }  }}

Option 2 — Self-Hosted (TypeScript / Node.js)

Run your own MCP server using this TypeScript implementation.

Prerequisites

  • Node.js 18+

Run via npx (no install)

bash
