Overview

Description from the maker (original English)

Render markdown into email-safe HTML, lint drafts for deliverability problems, and preview emails.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Open Claude Desktop → Settings → Connectors → Add custom connector, and paste this address

https://www.emailmd.dev/api/mcp

Runs on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "emailmd": {
      "command": "npx",
      "args": [
        "-y",
        "emailmd"
      ]
    }
  }
}

Run this in your terminal

claude mcp add --transport http emailmd https://www.emailmd.dev/api/mcp

Runs on your computer

Run this in your terminal

        "-y",
        "emailmd"
      ]
    }
  }
}

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "emailmd": {
      "type": "http",
      "url": "https://www.emailmd.dev/api/mcp"
    }
  }
}

Runs on your computer

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "emailmd": {
      "type": "stdio",
      "command": "npx",
      "args": [

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Compared with others in Chat & emaili

  • More stars than 83% of the other 6 servers in this category
  • Published to the registry more recently than 50% of the other 6 servers in this category
  • Basic checks equal to or better than 100% of the other 6 servers in this category

Compared only with servers in this prototype, not the whole registry.

Common questions

Is emailmd safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed 30 days ago, and the latest version (0.13.2) reached the registry 30 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Vexa, MCP WhatsApp Cloud, Gmail MCP Server

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

emailmd

Write markdown. Ship emails. No HTMHELL.

emailmd converts markdown into responsive, email-safe HTML that works across Gmail, Outlook, Apple Mail, Yahoo, and every other client.

Install

npm install emailmd

Quick Start

import { render } from "emailmd";

const { html, text } = await render(`

Welcome!

Thanks for signing up.

Get Started{button} `);

// html → complete email-safe HTML // text → plain text version for text/plain MIME part

v0.3.0 migration: render() is now async. Update calls from render(md) to await render(md). Requires Node 20+ (MJML 5).

Charts & Data

Bar charts, progress meters, sparklines, KPI tiles, step trackers, and star ratings, each written as a plain markdown list:

::: chart
  • Spotify: 16,900
  • Apple Podcasts: 12,400
  • Web player: 6,200
  • RSS: 2,900

:::

They are drawn from table cells and text glyphs rather than images or SVG, so they still render when the client blocks remote images, and they redraw themselves in the plain-text part instead of collapsing to a list of numbers. See the directives reference.

CLI

emailmd also ships with a command-line interface.

# Render to HTML

emailmd input.md

Write to file

emailmd input.md -o output.html

Plain text output

emailmd input.md --text

Pipe from another command

echo "# Hello" | emailmd

Run emailmd --help for all options.

React

@emailmd/react provides a live-preview hook (useEmailmd), an iframe component, and — the full builder as a drop-in component for your own app.

npm install @emailmd/react emailmd

  • Templates — ready-made email templates you can copy and customize
  • Builder — live editor to write and preview emails in your browser

MCP

emailmd ships a Model Context Protocol server, so an AI assistant can render, lint, and preview emails for you. It exposes three tools — render (markdown to email-safe HTML), lint (flag deliverability problems without rendering), and read_docs (look up emailmd syntax) — over either transport:

# Hosted (Streamable HTTP)

https://www.emailmd.dev/api/mcp

Or run it locally over stdio

npx emailmd mcp

Published to the official MCP registry as dev.emailmd/emailmd. See the MCP docs for per-client setup.

AI

Prefer plain context over tools? emailmd is just markdown, so AI is great at writing templates. Feed the full docs to your AI tool:

Contributing

Contributions are welcome! Feel free to open an issue or submit a pull request.

emailmd is under active development. The API may change between minor versions until we hit 1.0 — breaking changes are always called out in the changelog. See Stability & Versioning for what the semver contract covers.
