An MCP protocol server implemented for the Listmonk email system, providing AI models with the ability to manage mailing lists, subscribers, and newsletters through a standardized interface.

This project implements a Model Context Protocol (MCP) server that enables AI assistants like Claude to interact with Substack newsletters, articles, and authors through a standardized interface. It is based on the Substack API library and provides functions such as getting article content, searching for newsletters, and querying author information.

This project converts the Substack API into an Anthropic MCP server, enabling AI assistants such as Claude to interactively access Substack content, including obtaining newsletters, searching cross - magazine content, and discovering popular subscriptions.
