How to Use the MailerSend MCP in Cursor

Q: What's the difference between sendtransactionalemail and sendtemplatedemail in the MailerSend MCP server for Cursor?

sendtransactionalemail is for raw, custom HTML or text emails you define on the fly in your code. Use sendtemplatedemail to trigger pre-built designs stored in your MailerSend account, which is better for standardized messages like receipts or notifications.

Inject live MailerSend data and send emails without leaving your code in Cursor.

Perplexity

Draft Code with Real Template IDs

Tell Cursor's agent to write a function that sends a new user welcome email. Instead of inserting a placeholder string like `YOUR_TEMPLATE_ID`, the agent can call the `list_email_templates` tool on your actual MailerSend account. It finds the correct template, gets the real ID, and injects it directly into the generated code. This means the code works on the first run. No more switching tabs to copy-paste IDs or fixing runtime errors from typos.

Debug Delivery Issues In-Editor

When you're trying to figure out why a user didn't get an alert, you can work directly from your editor. Highlight a message ID from your application logs and ask the agent, "What's the status of this MailerSend message?" The agent uses `get_message_info` to get the full delivery history—bounces, clicks, opens—and presents it in the chat panel. You can debug email problems right next to the code that sent the message, which speeds things up considerably.

Build Analytics Views with this MCP Server

You can use the agent to build internal tools with live data. Ask Cursor to scaffold a simple dashboard component to show your team's email stats for the week. The agent will call `get_date_analytics` to get real numbers from MailerSend. It then uses that data to generate a working React or Vue component populated with actual metrics. You go from a prompt to a data-driven UI in a single step, which is perfect for building quick internal dashboards or reports.

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.

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.

Common questions about MailerSend MCP in Cursor

Switch to Agent mode and type, "Send a test email to me@example.com using MailerSend with the subject 'Test'." The agent will use the `send_transactional_email` tool and show you the API response.

Yes. Ask the agent to "List my verified sending domains in MailerSend." It uses `list_sending_domains` and `get_domain_details` to show you which domains are active and if their DNS records are correctly configured.

It lets the agent work with live data from your MailerSend account. Instead of guessing a template ID, it fetches real ones with `list_email_templates`. This simple step prevents typos and runtime errors caused by using stale or incorrect data in your code.

`send_transactional_email` is for raw, custom HTML or text emails you define on the fly in your code. Use `send_templated_email` to trigger pre-built designs stored in your MailerSend account, which is better for standardized messages like receipts or notifications.

Yes. The MCP server connects to MailerSend using an API key stored as a secret in your Vinkius account. Cursor itself never sees your key; it only communicates with your secure Vinkius endpoint, which handles the authentication.
