How to Use the MailerSend MCP in Cursor

Q: Can Cursor write email templates using live MailerSend data?

Yes. Cursor can pull your active domain list using listsenderdomains and generate code that references verified sender addresses.

Q: Can I monitor domain bounce rates from the editor?

Yes. You can have the editor call listdomainactivity to pull recent bounce and spam metrics, then display them in your terminal panel.

Write and test transactional email code with your Cursor MCP Server

Stop writing mock API tests for your MailerSend email code inside Cursor. When you run Cursor in Agent mode with this MCP server, the editor uses `send_transactional_email` to test real delivery while you write the integration. The Cursor Agent directly inspects real MailerSend API payloads to generate typed interfaces. Cursor knows the exact response structure because it pulls live data from MailerSend instead of guessing from outdated documentation.

Debug domain verification issues inside your editor

Setting up MailerSend DNS records inside Cursor can be a pain. Use Cursor to call `list_sender_domains` and see which domains are still pending verification without switching to a web browser. The Cursor editor uses `get_sender_domain_details` to fetch the required MailerSend TXT and MX records. You can write your DNS provisioning scripts in Cursor and verify them instantly using `verify_sender_domain` right in your terminal sidebar.

Trace sent messages and debug delivery failures

When debugging a failing webhook or a silent email drop, Cursor can query `list_sent_messages` to check recent outgoing traffic. You don't have to leave your Cursor workspace to hunt down MailerSend delivery logs. If a specific message failed, the Cursor editor calls `get_sent_message_details` to pull the raw SMTP response from MailerSend. This lets you debug MailerSend template logic or bad variables directly in your Cursor file by looking at the exact error returned.

Setup guide

Set up MailerSend MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the MailerSend MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent MailerSend transactions." If the MCP tools are loaded correctly, Cursor will call the MailerSend tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "mailersend-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}
