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, 47 tools) |
/mailercloud:campaign-audit | Audit a draft campaign before sending |
/mailercloud:analyze-campaigns | Analyze recent campaigns + action plan |
mailercloud-best-practices skill | Tool map, 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://….gitURL 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
