How to Use the Maileroo MCP in Windsurf

Q: How do I install the Maileroo MCP Server in Windsurf?

Open your mcpconfig.json file in /.codeium/windsurf/ or use the Cascade settings UI. Add the Maileroo server under the mcpServers key, then click refresh in the panel.

Q: Can Windsurf and Maileroo send actual emails during testing?

Yes. Cascade calls the sendtransactionalemail tool to dispatch real messages. You control the recipient list and payload directly through your prompt.

Q: Why does Windsurf need access to Maileroo webhooks?

Cascade uses listconfiguredwebhooks to verify your local endpoints match the live configuration. It checks if your local server is ready to catch bounce and delivery events.

Q: Does Cascade check domain records automatically?

You tell it to check. It runs getdomaindetails to pull your sender metadata. Then it reads the output to tell you if your authentication records are active.

Connect the Maileroo MCP server to Windsurf and let Cascade autonomously handle your transactional email infrastructure.

Windsurf MCP Server for Email Automation

The `send_transactional_email` tool triggers email delivery directly from your Windsurf editor. You give Cascade a target and a message payload. It formats the request, hits the Maileroo API, and fires off the notification without you switching to a browser. Cascade chains this with `list_email_templates` to pull available layouts before sending. It reads the template variables, maps them to your local mock data, and executes a test run so you can verify the output right in your terminal window.

Audit Sending Activity Automatically

The `list_sending_activity` tool pulls recent delivery logs straight into your workspace. When an email bounces during local testing, Cascade fetches the event logs to show you exactly why it failed. Instead of digging through a web dashboard, you ask Windsurf to check the status of your last dispatch. It uses `get_domain_details` to verify your DKIM and SPF records are actually set up correctly, then reports the findings in your active chat.

Webhook and Domain Management

The `list_configured_webhooks` tool returns every endpoint currently receiving Maileroo events. Cascade reads this list and compares it against your local route definitions to find missing handlers. It pairs this with `list_sending_domains` to audit your active sender profiles. If you need to map a new domain for a staging environment, Cascade checks the existing configurations and drafts the necessary DNS records for you to apply.
