Common questions

Is Mailercloud safe?

It passed 1 of 1 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?

You need to fill in: Authorization

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 (2.0.1) reached the registry 25 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?

Mailercloud plugin for Claude Code

Bundles the Mailercloud MCP server together with ready-made commands, a best-practices skill, and a campaign-manager subagent — so Claude Code users get expert Mailercloud workflows out of the box, not just the raw tools.

This is a Claude Code plugin. For claude.ai / Desktop / Mobile, use the Mailercloud

connector in the Claude directory instead — same server, broader reach.

What's inside

Piece	What it adds
`.mcp.json`	Connects the Mailercloud MCP server (`https://mcp.mailercloud.com/mcp`, 50+ tools, 4 guided prompts)
`/mailercloud:campaign-audit`	Audit a draft campaign before sending
`/mailercloud:analyze-campaigns`	Analyze recent campaigns + action plan
`/mailercloud:clean-list`	Clean a list safely: preview suppressions, segment non-openers, offer verification
`mailercloud-best-practices` skill	Tool map, term-to-action glossary, pre-send checklist, deliverability & metric guidance
`campaign-manager` agent	A specialist persona for multi-step campaign work

No changes to the Mailercloud server are required — the plugin only references it.

Install

Run these in Claude Code one at a time (each is a separate slash command — enter the first, wait for it to finish, then enter the second). Do not paste both lines together.

1. Add the marketplace:

/plugin marketplace add https://github.com/mailercloud-com/mailercloud-plugin.git

2. Install the plugin:

/plugin install mailercloud@mailercloud

Use the full `https://….git` URL above. The GitHub shorthand

(mailercloud-com/mailercloud-plugin) makes Claude Code clone over SSH, which fails if you

don't have GitHub SSH keys configured. The HTTPS URL works for everyone.

Then restart Claude Code if prompted, and try /mailercloud:campaign-audit.

Install in Gemini CLI

gemini extensions install https://github.com/mailercloud-com/mailercloud-plugin

Then run /mcp in Gemini CLI. mailercloud should be listed, and Gemini will ask you to sign in to Mailercloud the first time a tool runs.

Install in Cline and other MCP clients

Mailercloud is a hosted MCP server at https://mcp.mailercloud.com/mcp (Streamable HTTP, OAuth sign-in). Step-by-step setup for Cline and other agents is in llms-install.md.

Requirements & authentication

A Mailercloud account (sign up at https://mailercloud.com).
The first time a Mailercloud tool runs, Claude Code connects the MCP server and prompts you to authorize — sign in to Mailercloud (OAuth) or provide a Mailercloud API key. Until you authorize, the tools will report that authentication is required; this is expected.

Verify it installed

/plugin list                     # should show: mailercloud@mailercloud

You should also see /mailercloud:campaign-audit and /mailercloud:analyze-campaigns in the slash-command list, and the mailercloud MCP server under your connected tools.

Local development

To test changes without publishing, add the folder as a local marketplace:

/plugin marketplace add ./mailercloud-plugin

/plugin install mailercloud@mailercloud
