How to Use the MailerLite MCP in Windsurf

Q: How do I configure the MailerLite MCP server in Windsurf?

Open your mcpconfig.json file in the /.codeium/windsurf/ directory. Add the server details under the mcpServers object. You can also use the Cascade UI to refresh the connection instantly.

Q: Can Windsurf fetch specific subscriber records from MailerLite?

Yes. Cascade uses the getsubscriber tool to pull individual user profiles. You just provide the email address, and the agent retrieves their status and engagement history.

Q: Will Windsurf automatically update existing MailerLite subscribers?

It does. The upsertsubscriber tool handles both creation and updates. Cascade figures out if the user exists and patches their first or last name accordingly.

Automate Group Syncs with the MCP Server

The `create_group` tool lets Cascade build new audience segments the second you define a campaign goal. Instead of clicking through a dashboard, your agent handles the structural setup in the background. It reads your project context and immediately provisions the necessary marketing containers. Once the group exists, Cascade chains directly into `upsert_subscriber`. You drop a list of user emails into your IDE, and Windsurf pushes them straight to the new group. No manual CSV uploads. No mapping errors. The agent does the heavy lifting while you keep coding.

Audit Custom Fields and Forms

Running `list_custom_fields` gives your MCP client instant visibility into your existing subscriber data schema. You never have to guess if a field is named 'first_name' or 'FirstName' when writing integration code. Cascade pulls the exact mapping constraints directly from your account. It pairs this with `list_forms` to audit where your leads actually originate. If you need to build a custom landing page, Windsurf inspects the live forms and generates HTML that perfectly matches your current intake requirements.

Track Campaigns and Webhooks

Use `list_campaigns` to pull live marketing activity straight into your workspace. Cascade reviews recent email deployments to ensure your new transactional triggers don't collide with scheduled newsletters. You see the deployment reality without leaving the editor. From there, your agent can run `list_webhooks` to verify your server is catching the right events. If a webhook is missing, Windsurf knows exactly what configuration gap to fix in your backend code.
