## Description
Verify email addresses, clean lists and check spamtrap, disposable, spambot and complainer lists.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "smtping-email-verification": {
    "command": "npx",
    "args": ["-y","smtping-email-verification"]
  }
}
```

## Documentation & README

# SMTPing MCP server

Official [Model Context Protocol](https://modelcontextprotocol.io) server for [SMTPing](https://smtping.com). 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

| tool | what it does | credits |
| --- | --- | --- |
| `verify_email` | Verifies one address: status plus band (safe, avoid, judgement) | 1 |
| `verify_list` | Verifies a list as one bulk job (up to 100,000), waits for results | 1 per unique address |
| `get_bulk_job` | Progress and results of a bulk job | 0 |
| `check_threat` | Looks up one address in the spamtrap, disposable, spambot or complainer list | 1 |
| `get_credits` | Remaining credits and plan | 0 |

## Setup

Create an API key in the [SMTPing dashboard](https://app.smtping.com), then add the server to your client. Node 18 or later is required.

### Claude Desktop

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

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

Restart Claude Desktop.

### Claude Code

```bash
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`:

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

### Windows

If `npx` is not found, use `"command": "cmd"` and `"args": ["/c", "npx", "-y", "@smtping/mcp"]`.
