SMTPing 官方 MCP 服务器，让助手验证邮箱地址、清洗名单并查询威胁名单，消耗 SMTPing 付费额度。
Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/io.github.smtping%2Fsmtping-mcp/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

}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
