io.github.smtping由 GitHub 帳號 smtping 發布v1.0.1更新於 Nov 2, 2026
Verify email addresses, clean lists and check spamtrap, disposable, spambot and complainer lists.
SMTPing 官方 MCP 伺服器，讓助理驗證電子郵件地址、清理名單並查詢威脅名單，會消耗 SMTPing 付費額度。
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.github.smtping%2Fsmtping-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。把它新增到你客戶端的 mcpServers 設定中。 客戶端會在首次連接時完成 OAuth 登入。

}Official Model Context Protocol server for SMTPing. It lets Claude, Cursor, VS Code, Windsurf and any MCP client verify email addresses in a conversation.
"Verify these 40 leads and tell me which ones are safe to email."
Prefer not to run Node? Add https://mcp.smtping.com/mcp as a custom connector in Claude (Settings > Connectors) or ChatGPT, then sign in with your SMTPing API key. Same 5 tools, OAuth 2.1, nothing stored on the server. Source: smtping/smtping-mcp-remote.
Create an API key in the SMTPing dashboard, then add the server to your client. Node 18 or later is required.
Settings > Developer > Edit Config, then add to claude_desktop_config.json:
Restart Claude Desktop.
~/.cursor/mcp.json (or .cursor/mcp.json in a project): same JSON block as Claude Desktop.
.vscode/mcp.json:
npx is not found: use "command": "cmd" and "args": ["/c", "npx", "-y", "@smtping/mcp"].
"Request timed out" or "Server disconnected" on first start: the first npx run downloads the package and can take longer than the client's 60 second startup limit. Install the server once, then point the client to it:
npm install -g @smtping/mcpsmtping block with:Replace YOUR_NAME with your Windows user folder (spaces are fine) and use double backslashes. Run echo %APPDATA% to see the exact path. This form also avoids issues with .cmd launchers when the user folder contains a space.
To update later: npm install -g @smtping/mcp@latest.
Logs: Claude Desktop writes them to %APPDATA%\Claude\logs\mcp-server-smtping.log.
Addresses are sent to the SMTPing API only when a tool is called. See the privacy policy.

Verifies a list of addresses as one SMTPing bulk job (deduplicated, up to 100,000). Waits up to 120 seconds; if the job is still running, returns a job_id to pass to get_bulk_job later. Costs 1 credit per unique address.
emails必填wait_secondsGet a bulk job
