Hex MCP Server

A Model Context Protocol (MCP) server that provides real-time Hex package version information to AI tools like Cursor. This service helps ensure that AI-assisted development uses the correct and most up-to-date package versions when adding dependencies to Elixir projects.

What is MCP?

The Model Context Protocol (MCP) is an open protocol that standardizes how applications provide context to Large Language Models (LLMs). Think of it like a USB-C port for AI applications. For more information about MCP, visit the official documentation.

Using with Cursor

Cursor supports MCP servers out of the box. To get accurate Hex package version suggestions in your Elixir projects, add this server to your Cursor configuration.
