Overview

AI-generated overview

Hosted Mailercloud MCP server that lets an assistant manage email marketing campaigns, contacts, templates, sending and analytics.

What you can do
  • Manage email campaigns, including auditing drafts and analyzing recent campaign results
  • Work with contacts and lists, such as previewing suppressions and segmenting non-openers
  • Use and manage email templates
  • Send campaigns and review delivery and performance analytics
  • Follow guided prompts and a best-practices skill for deliverability and metric guidance
When to use it
Useful when you run email marketing in Mailercloud and want an assistant to draft, audit, clean and analyze campaigns without switching tools. Suited to Claude Code users who want the bundled commands and campaign-manager agent, or to other MCP clients that just need the hosted server.
Requirements
A Mailercloud account. The server is a remote Streamable HTTP endpoint; the first tool call triggers an OAuth sign-in or asks for a Mailercloud API key, sent as an Authorization bearer token. Network access to the hosted endpoint is required.
Before you install
The server acts on a live Mailercloud account: campaigns can be sent and lists or contacts changed, so review drafts and list-cleaning steps before confirming. Authorization is a bearer token or API key that grants account access; keep it private. Campaign and contact data is handled by Mailercloud as a third party.

Installation

In SourceWeft

  1. Open Mailercloud in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.mailercloud-com%2Fmcp-server/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

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

PieceWhat it adds
.mcp.jsonConnects the Mailercloud MCP server (https://mcp.mailercloud.com/mcp, 50+ tools, 4 guided prompts)
/mailercloud:campaign-auditAudit a draft campaign before sending
/mailercloud:analyze-campaignsAnalyze recent campaigns + action plan
/mailercloud:clean-listClean a list safely: preview suppressions, segment non-openers, offer verification
mailercloud-best-practices skillTool map, term-to-action glossary, pre-send checklist, deliverability & metric guidance
campaign-manager agentA 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

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
