MailerLite MCP Server

This is the beta version of Model Context Protocol (MCP) server that provides seamless integration with MailerLite's email marketing API. This server enables AI assistants to manage subscribers, campaigns, groups, and many other things through standardized MCP tools.

How MCP Works

The Model Context Protocol (MCP) is a standardized protocol for AI assistants to interact with external systems. Think of it as USB-C port for AI. You can connect multiple MCPs that talk to each-other and get things done for you.

Connecting a Client

You can connect any MCP-compatible client to the running server. The server supports a streamable HTTP endpoint up to the latest MCP server specifications. Usually, you would just add https://mcp.mailerlite.com/mcp as a remote MCP address in any tooling that you are working with.

Claude (desktop and web)

Open Claude (Desktop), go to Settings > Connectors, and then Add Custom Connector. Name can be whatever you want, but we suggest using MailerLite as name, and Remote MCP server URL is https://mcp.mailerlite.com/mcp. Click connect and follow the login process.

Claude Code

Execute this in terminal:

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