概覽

AI 產生的概覽

LookupLab 是遠端 MCP 伺服器，讓助理透過你的 LookupLab 帳戶查詢手機號碼電信商、電子郵件網域、IP 網路與 DNS 資訊。

可以做什麼
  • 查詢手機號碼的電信商與線路類型，可選提供美加發話者姓名資料
  • 驗證電子郵件地址的語法、MX 記錄、一次性網域與角色地址特徵
  • 查詢 IP 的概略位置與網路／服務商指標
  • 檢查網域的 MX、SPF、DMARC 或 DKIM 記錄並回報問題
適用情境
適合在對話中做快速的資料清理與寄送性檢查：驗證電子郵件名單、核對手機號碼、判斷 IP 所屬網路，或稽核網域的郵件驗證記錄。每次查詢都會消耗付費額度，因此較適合零星核驗而非批次處理。
執行需求
遠端端點 lookuplab.io，使用 Streamable HTTP，不需安裝本機套件。需要 LookupLab 帳戶、可用額度與 API 金鑰，透過 X-API-Key 標頭或 Bearer 權杖提供，或在 Claude 中以 OAuth 登入。Claude Code 方式使用 LOOKUPLAB_API_KEY 環境變數。DKIM 檢查需提供 selector。
安裝前請注意
所有工具都會扣抵帳戶額度（手機號碼查詢依線路類型與發話者姓名扣 1 至 5 點，其他查詢扣 1 點），且執行前餘額須足以支付最高扣費。重複呼叫可能再次扣費，除非用戶端送出穩定的 Idempotency-Key 標頭。結果無法證明身分、歸屬、聯絡同意、郵件可達性或精確位置，隱私標記可能缺漏。只提交你有權查詢的資料，並避免把 API 金鑰寫入共享儲存庫或聊天訊息。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 LookupLab，將其新增到工作區。
  2. 連接 X-API-Key 憑證。它們會被私密儲存，絕不會在公開頁面上展示。
  3. 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.PpiNeaPpLe%2Flookuplab/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。

LookupLab integrations

[M8ven Score]

Phone carrier, email-domain, IP-network and DNS checks through LookupLab.

Find LookupLab on Smithery and in the official MCP Registry.

Claude web and Desktop

  1. Open Customize > Connectors > Add custom connector. Name it LookupLab and use https://lookuplab.io/api/mcp.
  2. Choose Sign in now and Register automatically if Claude shows authentication options. Leave a custom client ID and secret blank.
  3. On LookupLab's consent page, enter your LookupLab key and approve. Enable the connector in your chat. Try: "Check the mail records for example.com."

Your key goes only to LookupLab; Claude receives a revocable OAuth connection. On Team and Enterprise plans, an owner first adds the connector, then each member connects their account. See Claude's connector setup.

Claude Code

Set LOOKUPLAB_API_KEY privately in your environment, then merge claude-code.mcp.json into your project's .mcp.json. Start Claude Code in that project, approve LookupLab when prompted, and check /mcp. Keep the variable reference in the file; never replace it with a real key in a shared repository.

The config uses Claude Code's HTTP transport and environment expansion. Try: "Check the mail records for example.com."

Gemini CLI

Install with gemini extensions install https://github.com/PpiNeaPpLe/lookuplab-integrations. Supply your existing LookupLab API key in the extension's sensitive setting. Gemini stores this setting in its system keychain when available. Never put a key in a chat message.

Other MCP clients

Connect to https://lookuplab.io/api/mcp with Authorization: Bearer YOUR_API_KEY or X-API-Key: YOUR_API_KEY in the client's secure connection settings. The server uses Streamable HTTP with JSON responses and no SSE stream.

ChatGPT and Codex

The openai/ directory is the portable plugin package. OAuth needs an exact callback registered by LookupLab before the platform connection can run. This source package is not a claim of directory approval or publication.

Tools and costs

ToolChecksAccount credits
phone_lookupCarrier, line type; optional caller name1 for landline/VoIP/toll-free, 3 mobile/unknown; caller name adds 2
email_verifySyntax, MX and domain indicators1
ip_lookupApproximate location and network1
dns_checkMX, SPF, DMARC or DKIM1

The account needs enough balance for the maximum charge before the lookup runs. Failed/invalid results are not charged. Tools debit credits, so they are marked as operations with side effects. Duplicate calls may charge again unless your client sends a stable Idempotency-Key header for retries.

Data is not proof of a person's identity, ownership, consent to contact, guaranteed email delivery or precise location. Privacy flags can be unavailable. Supply only data you are authorized to check.
