Overview

What is Email Server?

Email Server is a Model Context Protocol (MCP) server for sending emails via SMTP. It is SMTP provider agnostic, allowing use of any SMTP relay service (e.g., Gmail, SendGrid, Mailgun) by configuring environment variables. It is intended for AI assistants or MCP clients that need to send emails programmatically.

How to use Email Server?

Clone the repository, install dependencies with npm install, and build with npm run build. Configure the required environment variables (SMTP_HOST, SMTP_PORT, SMTP_USER, SMTP_PASSWORD, EMAIL_FROM) in the MCP client settings. The server exposes two tools: send_email (to send an email to a specified recipient) and test_email (to verify the configuration).

Key features of Email Server

Send emails to specified recipients via SMTP.
Test email functionality for configuration verification.
Environment variable configuration for SMTP credentials.
Proper error handling and logging.
TypeScript implementation for type safety.

Use cases of Email Server

AI assistants sending notifications or alerts via email.
Automating email dispatch from MCP-compatible clients.
Testing SMTP configuration before production use.

Frequently asked questions

What environment variables are required?

The required variables are `SMTP_HOST`, `SMTP_PORT`, `SMTP_USER`, `SMTP_PASSWORD`, and `EMAIL_FROM`. Optional variables include `SMTP_SECURE`, `SMTP_REJECT_UNAUTHORIZED`, and `SMTP_TIMEOUT`.

What transport type does Email Server use?

It uses `stdio` transport, as shown in the MCP configuration example.

Is Email Server tied to a specific email provider?

No. It is SMTP provider agnostic and works with any SMTP relay service (e.g., Gmail, SendGrid, Mailgun) by configuring the appropriate environment variables.

What tools does Email Server provide?

It provides `send_email` (requires `recipient` and `body` parameters) and `test_email` (no parameters).

How do I configure the server for my MCP client?

Add a `"email-server"` entry to your MCP settings JSON, specifying `command: "node"`, `args` pointing to the built `index.js`, and `env` with your SMTP credentials.
