email-verifier-mcp

An MCP (Model Context Protocol) server for verifying email addresses using the RightEmails API. Connect it to Claude and verify emails using natural language.

Installation

pip install email-verifier-mcp

Prerequisites

You need a RightEmails account to get:

• RIGHTEMAILS_API_KEY — your API key
• RIGHTEMAILS_REQUEST_ORIGIN — the email address registered with your API key

Setup with Claude Code

Run this command to add the MCP server:

claude mcp add email-verifier email-verifier-mcp \
  -e RIGHTEMAILS_API_KEY=your-api-key \
  -e RIGHTEMAILS_REQUEST_ORIGIN=your@email.com

Setup with Claude Desktop

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "email-verifier": {
      "command": "email-verifier-mcp",
      "env": {
        "RIGHTEMAILS_API_KEY": "your-api-key",
        "RIGHTEMAILS_REQUEST_ORIGIN": "your@email.com"
      }
    }
  }
}

Usage

Once connected, just ask Claude naturally:

"Verify this email: john@example.com"

"Check if these emails are valid: alice@company.com, bob@gmail.com, carol@domain.org"

Claude will handle the verification and return results for each email.
