MailTempo

Installation

Use the remote endpoint directly:

• https://mailtempo.com/api/mcp (Streamable HTTP)
• For stdio-only clients, wrap it with npx -y mcp-remote https://mailtempo.com/api/mcp

Configuration

No authentication is required. The endpoint is public and rate-limited per IP.

Capabilities

• list_domains: list active catchall domains
• list_messages: list recent messages for a public MailTempo address
• get_message: fetch a single message with sanitized HTML, plain text, headers, attachment metadata, and OTP

Limitations

• Inboxes are public by design
• Mail history is retained for 60 days
• The Gmail backend syncs about once a minute
• OTP extraction is best-effort
• Not suitable for banking, government, or other security-critical accounts
