Summary generated from the project's README
About Rowsend MCP server
Rowsend connects AI agents to your marketing database and email infrastructure through a local desktop application. This setup allows developers using clients like Claude Desktop, Cursor, or Claude Code to manage email marketing workflows directly from their chat interface. The server works by communicating with the Rowsend app running on your macOS machine, ensuring that sensitive contact data and API keys remain on your computer rather than being sent to the cloud.
Agents can interact with various databases including Postgres on Supabase or Neon, MySQL, PlanetScale, MongoDB, and Firebase Auth. They can also interface with sending providers such as SES, Postmark, Mailgun, or SMTP. While the agent can perform many tasks like creating campaigns, listing segments, and uploading images, it cannot actually send or schedule a campaign. You must manually click the send button within the Rowsend app to finalize any mailing. This architecture provides a controlled environment where the AI handles the heavy lifting of drafting and organization while you maintain final authority over the actual delivery.
What you can do with it
- 1Drafting brand-aligned email campaignsAsk an AI agent to write a new email campaign using your existing brand guidelines and templates.
- 2Managing marketing contact segmentsInstruct your agent to create a new audience segment from your connected database.
- 3Automating database and sender configurationUse the setup skill to guide an agent through connecting your database and email provider.

View on GitHubRowsend 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.

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.

Rowsend MCP questions
How do I add Rowsend MCP to Claude Code?
Run claude mcp add mcp -- npx -y @rowsend/mcp in your terminal. Add --scope user to make it available in every project.
How do I add Rowsend MCP to Cursor?
Open ~/.cursor/mcp.json and add the server under mcpServers, using the Cursor config shown in the install section above.
Can the AI agent send marketing campaigns automatically?
No, agents cannot send or schedule campaigns; only you can perform those actions within the Rowsend app.
Does the agent have access to my database passwords or API keys?
No, the agent cannot see or type passwords or API keys because Rowsend opens dedicated screens for you to enter them.
What databases are supported by Rowsend?
Rowsend supports Postgres on Supabase or Neon, MySQL, PlanetScale, MongoDB, and Firebase Auth.
