Overview

AI-generated overview

Connects an AI assistant to the Rowsend desktop app so it can draft, preview and test marketing email campaigns against your own contact database.

What you can do
  • List and create projects, and check data source status
  • Connect a database, map contact fields, sync contacts and set the sync interval
  • Inspect contacts and segments, preview audiences, add suppressions, manage topics
  • Read brand and templates, create or update templates, list and upload images, preview emails
  • Create, update, duplicate and inspect campaigns, send tests, read stats, pause, resume, cancel or retry failures
  • Set up and verify senders, bounce handling and sending limits
When to use it
Useful if you run marketing email from the Rowsend desktop app and want an assistant to help write campaigns in your brand, prepare audiences and preview or test drafts, while you keep the final send in the app.
Requirements
macOS with the Rowsend app installed in Applications, plus Node.js 18 or later; the npm package is launched with npx. If the app is elsewhere, set the ROWSEND_APP environment variable to its path. The first connection must be approved in the app.
Before you install
The assistant can create and change data: projects, templates, segments, suppressions, campaigns and sending settings. It cannot send or schedule campaigns, delete anything, or see passwords and API keys, which are entered in the app's own screens. Access is granted per client and stored as an encrypted token on your machine; revoke clients in the app's MCP settings.

Installation

In SourceWeft

  1. Open Rowsend in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

Rowsend MCP server

[Listed on mcpservers.org] [M8ven Score]

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

Install

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

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

Claude Code:

bash
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:

bash
claude plugin marketplace add rowsend/mcpclaude plugin install rowsend@rowsend

Codex:

bash
codex plugin marketplace add rowsend/mcpcodex 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.

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.

License

MIT. This license covers this launcher. The Rowsend app has its own terms.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
