已驗證Streamable HTTP可網頁執行溝通與協作商業與電商

概覽

AI 產生的概覽

ListCheckup 為 AI 助理提供電子郵件地址與名單驗證,並在消耗額度前先顯示價格。

可以做什麼
  • 驗證單一電子郵件地址,回傳狀態、原因與信心分數
  • 查詢帳戶剩餘額度
  • 提交名單以取得報價,確認後再開始檢測
  • 追蹤名單檢測進度,並在完成後讀取各狀態的數量統計
適用情境
適合助理處理聯絡人或潛在客戶資料時,在寄送前確認哪些地址可送達,或在動用額度前先估算整份名單的驗證成本。
執行需求
遠端 Streamable HTTP 端點,無需本機安裝。需要 ListCheckup 帳戶,並以 Authorization 標頭攜帶 Bearer API 金鑰。需要能連線至該服務的網路。
安裝前請注意
API 金鑰可消耗帳戶額度,請勿放入共用儲存庫,外洩後應立即撤銷。開始名單檢測會消耗額度,但報價與開始是分開的工具,可先顯示費用。僅能驗證自己已持有的地址,不允許使用購買、租用或擷取來的名單。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 ListCheckup,將其新增到工作區。
  2. 連接 Authorization token 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/com.listcheckup%2Fmcp/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

ListCheckup MCP server

Email verification for AI assistants. Connect Claude, Cursor or any MCP client to ListCheckup and let it check a single address or a whole list, showing you the price before anything is spent.

  • Endpoint: https://listcheckup.com/mcp (remote, Streamable HTTP)
  • Auth: Authorization: Bearer lck_live_... (create a key in your ListCheckup dashboard)
  • Free tier: 100 checks every month, no card. Catch-all and unknown results are not charged, and credits never expire.
  • Data: processed on EU servers. Nothing is sent to the addresses being checked.

Tools

ToolWhat it doesCost
check_emailVerify one address: valid, invalid, risky, catch-all or unknown, with the reason and a confidence score1 credit (free if catch-all or unknown)
get_balanceCredits left on the accountFree
create_listSubmit a list and get its priceFree
start_listStart checking a list you've pricedSpends credits
get_listStatus and progress of a listFree
get_list_summaryCounts by status once a list is finishedFree

Pricing and starting are separate tools on purpose: an assistant has to show you what a list will cost before anything is spent, and you can say no. No tool takes an account as an argument; the key in the header decides whose credits are used.

Connect

Claude Code

bash
claude mcp add --transport http listcheckup https://listcheckup.com/mcp \  --header "Authorization: Bearer lck_live_..."

Claude Desktop, Cursor and most other clients

json
{  "mcpServers": {    "listcheckup": {      "url": "https://listcheckup.com/mcp",      "headers": { "Authorization": "Bearer lck_live_..." }    }  }}

Check it works

bash
curl -X POST "https://listcheckup.com/mcp" \  -H "Authorization: Bearer lck_live_..." \  -H "Content-Type: application/json" \  -H "Accept: application/json, text/event-stream" \  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Six tools listed means you're connected.

Example prompts

  • "Check whether [email protected] is a real address."
  • "Here's my leads CSV. How much would it cost to verify it? Don't start until I say so."
  • "How many credits do I have left?"

Treat the key as a password

Anything holding it can spend your credits. Keep config files with the key out of shared repositories, give each machine its own key, and revoke a key in the dashboard if it leaks. Revoking takes effect immediately.

Links

ListCheckup checks addresses you already hold. Purchased, rented or scraped lists aren't allowed under the acceptable use policy.
