What is Mailercloud MCP?

Mailercloud lets an AI client manage email marketing campaigns, contacts, templates, and analytics through specialized tools and agents.

Summary generated from the project's README

About Mailercloud MCP server

Managing email marketing campaigns, contact lists, and performance analytics is possible directly through an AI client using Mailercloud. This plugin for Claude Code provides a specialized campaign-manager agent and a best-practices skill to help users move beyond raw tool usage into expert workflows. It connects to a hosted MCP server that offers over 50 tools and four guided prompts to assist with marketing tasks.

Developers and marketers can use this via Claude Code, Gemini CLI, or other MCP clients like Cline. Setup requires a Mailercloud account, and the first time a tool is used, the client will prompt for authorization via OAuth or an API key. The system includes specific slash commands such as campaign-audit for reviewing drafts, analyze-campaigns for generating action plans from recent data, and clean-list for managing subscriber segments and suppressions.

What you can do with it

1Audit draft email campaignsAsk the AI to review a campaign draft for errors before it is sent to subscribers.
2Analyze marketing performanceRequest a detailed analysis of recent email campaigns along with a suggested action plan.
3Clean subscriber contact listsInstruct the agent to segment non-openers and preview suppressions to maintain list health.
4Execute multi-step marketing workflowsHand off complex, multi-stage campaign management tasks to a specialized agent persona.

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
