Sequenzy MCP Server

Official MCP server for Sequenzy, the AI-powered email marketing platform.

Connect Sequenzy to Claude Desktop, Claude Code, Codex, Cursor, Windsurf, VS Code Copilot, OpenClaw, and other MCP clients so your AI assistant can manage email operations with structured tools instead of hand-written API calls.

What You Can Do

• Manage subscribers, tags, lists, and dynamic segments.
• Draft, update, schedule, and inspect campaigns.
• Create and edit email sequences, including event-triggered and segment-entry automations.
• Manage transactional email templates and send single transactional emails.
• Generate email copy, subject lines, and multi-step sequences.
• Inspect analytics, subscriber activity, deliverability health, and dashboard URLs.
• Configure sender websites and pull integration examples for common frameworks.

Quick Setup

The easiest setup path is the Sequenzy wizard:

npx @sequenzy/setup

The wizard opens the browser login flow, creates a personal API key, detects supported AI clients, and configures them automatically when possible.

Manual Setup

All stdio MCP clients use the same command:

• Command: npx
• Args: -y @sequenzy/mcp
• Required env: SEQUENZY_API_KEY=seq_user_your_key_here

Optional environment variables:

• SEQUENZY_API_URL - Sequenzy API base URL. Defaults to https://api.sequenzy.com.
• SEQUENZY_APP_URL - Sequenzy dashboard base URL used by app URL helpers. Defaults to https://sequenzy.com.

Claude Desktop

Add this to your Claude Desktop config:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "sequenzy": {
      "command": "npx",
      "args": ["-y", "@sequenzy/mcp"],
      "env": {
        "SEQUENZY_API_KEY": "seq_user_your_key_here"
      }
    }
  }
}

Restart Claude Desktop after editing the config.

Claude Code

claude mcp add --scope user --env=SEQUENZY_API_KEY=seq_user_your_key_here sequenzy -- npx -y @sequenzy/mcp

On native Windows, wrap npx with cmd /c:

claude mcp add --scope user --env=SEQUENZY_API_KEY=seq_user_your_key_here sequenzy -- cmd /c npx -y @sequenzy/mcp

For a shared project config, use .mcp.json:

{
  "mcpServers": {
    "sequenzy": {
      "command": "npx",
      "args": ["-y", "@sequenzy/mcp"],
      "env": {
        "SEQUENZY_API_KEY": "seq_user_your_key_here"
      }
    }
  }
}

Codex

codex mcp add sequenzy --env SEQUENZY_API_KEY=seq_user_your_key_here -- npx -y @sequenzy/mcp
codex mcp list

Manual Codex config in ~/.codex/config.toml:

[mcp_servers.sequenzy]
command = "npx"
args = ["-y", "@sequenzy/mcp"]

[mcp_servers.sequenzy.env]
SEQUENZY_API_KEY = "seq_user_your_key_here"

Cursor

Add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "sequenzy": {
      "command": "npx",
      "args": ["-y", "@sequenzy/mcp"],
      "env": {
        "SEQUENZY_API_KEY": "seq_user_your_key_here"
      }
    }
  }
}

Windsurf

Use the same JSON shape as Cursor.

• macOS: ~/Library/Application Support/Windsurf/mcp.json
• Windows: %APPDATA%\Windsurf\mcp.json

VS Code Copilot

VS Code uses a servers object:

{
  "servers": {
    "sequenzy": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@sequenzy/mcp"],
      "env": {
        "SEQUENZY_API_KEY": "seq_user_your_key_here"
      }
    }
  }
}

Other MCP Clients

For OpenClaw, Hermes, and other MCP-compatible clients, point the client at npx -y @sequenzy/mcp and set SEQUENZY_API_KEY.

Getting an API Key

1. Open the Sequenzy dashboard.
2. Go to Settings -> API Keys.
3. Create a personal key.
4. Add the key to your MCP client config.

Personal keys start with seq_user_. You can revoke them any time in the dashboard.
