Questions

Rowsend MCP server

Rowsend is a desktop app for marketing email. It reads contacts from your own database (Postgres on Supabase or Neon, MySQL, PlanetScale, MongoDB or Firebase Auth) and sends through your own provider (SES, Postmark, Mailgun or SMTP). Contacts and keys stay on your computer.

This package connects an MCP client such as Claude Desktop, Cursor or Claude Code to the Rowsend app. Agents can connect your database, write campaigns in your brand, preview them and send you a test. You click Send in the app.

Requirements

macOS, with Rowsend installed in Applications. Download it from rowsend.com.
Node.js 18 or later.

Install

Claude Desktop, Cursor or any client with an mcpServers setting:

{
  "mcpServers": {
    "rowsend": { "command": "npx", "args": ["-y", "@rowsend/mcp"] }
  }
}

Claude Code:

claude mcp add rowsend -- npx -y @rowsend/mcp

Plugins for Claude Code and Codex

The plugin adds the MCP server and a rowsend-setup skill. The skill walks your agent through connecting your database and sender and drafting a first campaign.

Claude Code:

claude plugin marketplace add rowsend/mcp
claude plugin install rowsend@rowsend

Codex:

codex plugin marketplace add rowsend/mcp
codex plugin add rowsend@rowsend

The first time the client connects, Rowsend asks you to allow it. Click Allow. Rowsend keeps that client's token encrypted on your computer, so it asks only once. To cut a client off, revoke it in Rowsend → Settings → MCP.

If Rowsend is somewhere other than Applications, set ROWSEND_APP to its path, such as /Users/you/Apps/Rowsend.app.

What agents can't do

Send or schedule a campaign. Only you can, in the app.
Delete anything.
See or type a password or API key. Rowsend opens its own screens for you to paste them.
Turn off the unsubscribe footer, edit a segment or undo an unsubscribe.

The full guide is at rowsend.com/docs/agents/mcp.

How it works

Rowsend runs its MCP server inside the app, on 127.0.0.1 only. This package finds the app and starts it with --mcp-stdio, which passes messages between your client's stdin and stdout and that local server. If Rowsend isn't running, it opens in the background.
