Connect (Remote Server) Docs

Overview

The MailerLite MCP server is the official, provider-hosted Model Context Protocol integration from MailerLite (currently in beta). It exposes the MailerLite email marketing API to AI assistants as a remote HTTP MCP endpoint, letting agents read and modify subscribers, campaigns, groups, segments, automations, forms, and webhooks on behalf of an authorized user.

The server is hosted by MailerLite at https://mcp.mailerlite.com/mcp and uses OAuth, so there is no GitHub repo to clone or API key to manage. Users connect by adding the URL as a custom connector in Claude, Cursor, VS Code, ChatGPT (Pro/Plus developer mode), or Gemini CLI, then authorizing access in the browser.

Tool coverage spans the core MailerLite domains: subscriber CRUD plus activity and counts, campaign create/schedule/cancel, group membership management and bulk imports, segment listing and editing, automation activity tracking, form management, and webhook configuration. This makes it suitable for delegating routine email marketing operations (such as building re-engagement segments or drafting and scheduling newsletters) to an AI assistant.

Setup Guide

Prerequisites

A MailerLite account (a 14-day free trial of premium features is available without a credit card).
An MCP-compatible client: Claude (desktop or web), Claude Code, Cursor, VS Code with GitHub Copilot, ChatGPT (Pro/Plus with Developer Mode), or Gemini CLI.

The server is hosted by MailerLite at https://mcp.mailerlite.com/mcp. There is no install step or API key, authentication happens via OAuth in the browser when you first connect.

Claude Desktop / Claude Web

Settings, then Connectors, then Add custom connector. Enter:

Name: MailerLite
Remote MCP server URL: https://mcp.mailerlite.com/mcp

Click Add, then Connect, and authorize in the browser redirect.

Claude Code

claude mcp add --transport http mailerlite https://mcp.mailerlite.com/mcp

Cursor

Use the official Add to Cursor link from the MailerLite MCP docs, then click Needs login to authorize. Note: the Cursor free plan is limited to 40 active tools per connector, and MailerLite exposes more than that, so you may need to disable some tools.

VS Code

Install Visual Studio Code with GitHub Copilot, then use the one-click install link from MailerLite's docs to register the connector. Enable Agent mode in the chat panel.

Gemini CLI

Add the following to ~/.gemini/settings.json:

{
  "mcpServers": {
    "mailerlite": {
      "httpUrl": "https://mcp.mailerlite.com/mcp",
      "timeout": 30000
    }
  }
}

ChatGPT (Pro/Plus)

Settings, Connectors, Advanced Settings, toggle Developer Mode, then Create a new connector with name MailerLite and URL https://mcp.mailerlite.com/mcp. Authorize the redirect.

Use Cases

Draft, schedule, and cancel newsletters end to end (create_campaign, schedule_campaign, cancel_campaign) using subject lines and content generated from a blog post or product update.
Build re-engagement segments by combining list_subscribers, get_subscriber_activity, and update_segment to target subscribers who have not opened in 6+ months.
Bulk import contacts from a CSV or another tool into a specific group with create_group and import_subscribers_to_group, then verify with get_group_subscribers.
Analyze campaign performance across recent sends with list_campaigns and get_campaign_subscribers to identify top performing emails and patterns.
Set up event-driven integrations by creating and managing create_webhook / update_webhook entries that fire on subscriber and campaign events.

Example Prompts

"List my last 10 campaigns and tell me which had the highest open rate."
"Create a segment of subscribers who have not opened an email in 6 months and show me the count."
"Add john@example.com to the Newsletter group and tag them with source=podcast."
"Draft a welcome campaign for the Onboarding group from this blog post and schedule it for Tuesday 9am."
"Create a webhook that fires to https://example.com/hooks/mailerlite on subscriber.created events."

Pros

Official, provider-hosted server from MailerLite with OAuth, no API key handling or self-hosting required.
Broad tool coverage across subscribers, campaigns, groups, segments, automations, forms, and webhooks (40+ tools).
Works out of the box with Claude, Claude Code, Cursor, VS Code, ChatGPT Developer Mode, and Gemini CLI.

Limitations

Marked as beta, so behavior and tool surface may change.
Large tool count can exceed client limits, for example Cursor's free plan caps connectors at 40 active tools.
No public source code or self-hosted option, you must trust the hosted endpoint with OAuth-scoped access to your MailerLite data.

Alternatives

Mailchimp MCP server (community implementations on GitHub) for similar email marketing workflows on Mailchimp.
Resend MCP server for transactional and broadcast email aimed at developer-oriented stacks.
