From the SMTPing Email Verification repository's README, as published. We do not edit it. Read it on GitHub

SMTPing MCP server

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."

Tools

Setup

Create an API key in the SMTPing dashboard, then add the server to your client. Node 18 or later is required.

Claude Desktop

Settings > Developer > Edit Config, then add to claudedesktopconfig.json:

{
  "mcpServers": {
    "smtping": {
      "command": "npx",
      "args": ["-y", "@smtping/mcp"],
      "env": { "SMTPING_API_KEY": "sk_live_your_key_here" }
    }
  }
}

Restart Claude Desktop.

Claude Code

claude mcp add smtping -e SMTPING_API_KEY=sk_live_your_key_here -- npx -y @smtping/mcp

Cursor

~/.cursor/mcp.json (or .cursor/mcp.json in a project): same JSON block as Claude Desktop.

VS Code

.vscode/mcp.json:

{
  "servers": {
    "smtping": {
      "command": "npx",
      "args": ["-y", "@smtping/mcp"],
      "env": { "SMTPING_API_KEY": "sk_live_your_key_here" }
    }
  }
}
