Automate Subscriber Onboarding

This server gives Windsurf's Cascade agent direct access to your MailerLite subscribers. Tell it to "add new signups from the popup form to the newsletter group," and Cascade figures out the rest. It chains `list_forms` to find the right one, then uses `create_subscriber` and `add_subscriber_to_group` for you. You don't have to prompt each step. Cascade sees the goal, plans the tool sequence, and executes it. This is how you automate list management with an MCP Server without writing a single line of code or dealing with brittle sync scripts.

Clean Your Lists Autonomously

List hygiene is a pain. With this MCP Server, you can just tell Windsurf to "remove all bounced subscribers from the main list." Cascade will use `list_subscribers` with a status filter to find them, then run `delete_subscriber` on each one. It works for segmentation, too. Ask Windsurf to move subscribers from a "prospects" group to a "customers" group. It will use `remove_subscriber_from_group` and `add_subscriber_to_group` in sequence, handling the logic automatically.

Get Campaign Insights with Windsurf

Forget logging into the MailerLite dashboard just to check on a campaign. Ask Windsurf, "what were our last five campaigns?" and it uses the `list_campaigns` tool to pull the data right into your editor. You can also check on account status with `get_me` or see which signup forms are active with `list_forms`. It's all about getting quick answers without breaking your focus.

Common questions about MailerLite MCP in Windsurf

Windsurf uses its Cascade agent to chain multiple MailerLite tools together from a single instruction. You describe the outcome, and it figures out the steps using tools like `create_subscriber` and `add_subscriber_to_group` automatically. This MCP connection makes it possible.

Yes. You can tell Windsurf to "create a new group for the Q3 webinar attendees." It will use the `create_group` tool to make the new group directly in your MailerLite account.

The most direct way is to give Windsurf a goal like "add this user to our welcome sequence." Cascade will then use `create_subscriber` to add them to MailerLite and `add_subscriber_to_group` to place them in the correct automation group.

Just ask Windsurf to "get the details for subscriber jane@example.com." It will run the `get_subscriber` tool and show you their status, groups, and other info right in the chat.

This server only touches your MailerLite subscriber data, like emails and names, along with group lists and campaign metadata. All requests are proxied through Vinkius's ephemeral sandboxes, and your API key is encrypted and isolated. No subscriber data is ever stored long-term.
