Overview

Description from the maker (original English)

Read Enginemailer subscribers, lists and campaigns; add subscribers, create and send campaigns.

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.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 17 things (tools) enginemailer_get_subscriber, enginemailer_list_subscriber_categories, enginemailer_list_custom_fields, enginemailer_add_subscriber …
  • The registry lists no key to fill in.

Common questions

Is Enginemailer MCP by usefulapi safe?

It passed 3 of 3 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?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.14.3) reached the registry yesterday.

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: Spec Driven Development, Remote Desktop Commander, yontu

Enginemailer MCP by usefulapi

Read Enginemailer subscribers, lists and campaigns; add subscribers, create and send campaigns.

Live endpoint: https://enginemailer.usefulapi.io/mcp · Homepage: https://usefulapi.io/enginemailer

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://enginemailer.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http enginemailer https://enginemailer.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "enginemailer": { "url": "https://enginemailer.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Enginemailer credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/enginemailer/

On first connect you'll paste your Enginemailer API key (in Enginemailer open Manage account → API Keys and copy or create a key).
