What is the SMTP Email MCP server?

A Model Context Protocol server for SMTP email services. That is what the smtp email mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.

The short version

A Model Context Protocol (MCP) server that provides email sending capabilities for Claude and other MCP-compatible AI assistants.

  • Multiple SMTP Configurations — Configure and manage multiple SMTP servers
  • Email Templates — Create, update, and use reusable email templates
  • Bulk Email Sending — Send emails to multiple recipients with batching and rate limiting
  • HTML Support — Full HTML support for rich email content
  • Logging — Comprehensive logging of all email activities
  • Template Variables — Dynamic content using template variables

Getting it running

Installation goes through your MCP client rather than a global install: point it at @smithery/cli on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

The tools it exposes

The server publishes 1 tool. What each one is for:

  • Configuration — The Configuration tool exposed by this server

What it needs from you

Configuration is passed through the environment: NODE_PATH. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

  • Node.js 14+ - Nodemailer for email sending - Access to an SMTP server

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How it compares

Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. SMTP Email's toolset — Configuration — is a fair guide to whether it matches your workflow. It is maintained by samihalawa; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
