How to Use the MailerSend MCP in Windsurf

Q: Can I check my MailerSend domain status from Windsurf?

Yes. Ask Windsurf to check a domain, and it will use getsenderdomaindetails. It can also list all of them for you with listsenderdomains.

Let Windsurf's Cascade agent manage your MailerSend domains and send transactional emails for you, from setup to delivery confirmation.

Automate Domain Setup and Verification

This toolset lets Cascade handle your entire domain onboarding process. Just tell Windsurf to add a new sending domain. It will call `verify_sender_domain` to start the process, then repeatedly check the status using `get_sender_domain_details` until it's fully verified. You don't have to monitor DNS changes or manually check for completion. Cascade plans the sequence, executes it in the background, and just notifies you when your domain is ready to send email. It turns a multi-step chore into a one-line request.

Send and Track Emails with Windsurf

Give Windsurf a goal like 'send a welcome email to new_user@example.com'. It finds the `send_transactional_email` tool and executes it with the right parameters. You can pass simple text, HTML, or just a template ID and variables. After sending, ask for a status update. Cascade can chain the initial send with a follow-up call to `get_sent_message_details` or `list_domain_activity` to confirm the email was delivered. No more jumping between your code and a dashboard.

Manage Recipients with this MCP Server

Get a full picture of your audience directly in your IDE. Ask Windsurf to 'show me all recipients' and it will use `list_email_recipients` to pull the data. You can also get specific user info with `get_recipient_details`. This is great for quick checks without leaving your editor. Before you send a bulk campaign with `send_bulk_transactional_emails`, you can have Cascade run a quick script to validate a few recipients from the list first. This MCP Server makes that kind of check trivial.
