[![smithery badge](https://smithery.ai/badge/@atharvagupta2003/mcp-lemonsqueezy)](https://smithery.ai/server/@atharvagupta2003/mcp-lemonsqueezy)

A Model Context Protocol (MCP) server implementation that integrates with [Lemon Squeezy](https://www.lemonsqueezy.com/) for handling subscriptions, checkouts, products, and more. This server provides a structured interface to programmatically manage your Lemon Squeezy store with audit logging and tool-based control.
