FAQ from Java Mcp Server For Smtp Mailing

What prerequisites are needed to run the server?

Java 21 or higher, Maven 3.6+, a Gmail account with an app‑specific password (or other SMTP credentials), and an MCP client for testing (e.g., Claude Desktop or MCP Inspector).

How do I obtain a Gmail app password?

Enable 2‑factor authentication on your Gmail account, go to Google Account settings > Security > App passwords, generate a new password, and use it as the SMTP_PASSWORD value in the configuration.

Can I use a different SMTP provider besides Gmail?

Yes. Change the SMTP_HOST, SMTP_PORT, and TLS/SSL flags in Application.java. The README includes examples for Microsoft Outlook, Yahoo Mail, and custom SMTP servers.

What transport protocols are supported?

STDIO (for Claude Desktop and direct integration), Server‑Sent Events (SSE, for web applications), and Streamable HTTP (for testing and REST clients).

How can I test the server without an MCP client?

Use the REST endpoints. Start the server with --streamable-http, then send a POST request to http://localhost:45450/api/test-email with a JSON body containing to, subject, and body. A health check is available at GET /api/health.
