io.github.PanStories/email-verifier-mcp (MCP) Server

This MCP server provides tools to verify email deliverability using RFC-compliant checks, including validation of RFC format, MX records, and SMTP behavior. It also performs disposable-domain checks to determine whether an email address is likely associated with temporary or non-permanent domains.

🛠️ Key Features

  • MX record checks
  • SMTP deliverability verification
  • Disposable-domain checks

🚀 Use Cases

  • Validate whether an email address can accept mail based on domain and server records
  • Reduce bounce risk by checking MX/SMTP deliverability
  • Detect likely temporary email providers via disposable-domain rules

⚡ Developer Benefits

  • Additional disposable-domain filtering to support address quality

⚠️ Limitations

  • Scope is limited to email deliverability verification (format, MX, SMTP, disposable domains)
