Hex MCP Server

🚀 Hex MCP Server

A Model Context Protocol (MCP) server that provides real-time Hex package version information, helping AI tools (such as Cursor) obtain the correct Elixir project dependency versions. This service ensures that AI-assisted development uses the latest and correct package versions.

🚀 Quick Start

The Hex MCP Server offers real - time Hex package version information, facilitating AI tools like Cursor to acquire accurate Elixir project dependency versions.

✨ Features

What is MCP?

The Model Context Protocol (MCP) is an open protocol designed to standardize how applications provide context information to large language models (LLMs). You can think of it as the AI equivalent of a USB - C port for applications. For more information about MCP, visit the official documentation.

Using with Cursor

Cursor natively supports MCP servers. To get accurate Hex package version suggestions in your Elixir project, add this server to your Cursor configuration.
