Building Your Own MCP Server for Claude Code

This guide will walk you through creating a custom MCP (Model Context Protocol) server that integrates with Claude Code, allowing you to extend Claude's capabilities with external tools, APIs, or even other AI models.

What is MCP?

MCP (Model Context Protocol) is a protocol that allows Claude to communicate with external servers to access tools and capabilities beyond its built-in features. Think of it as a plugin system for Claude.

Prerequisites

From `init.lua` to `default.nix`

In a previous post I explained how to manage Neovim plugins with Nix and Home Manager. In this post I want to go further and show how to migrate Neovim configuration from ~/.config/nvim to ~/.config/home-manager entirely. The end result will be to split our Neovim setup into multiple modules that colocate plugin sourcing and configuration.

If you haven't read the post linked above, do so now. We will assume the

Manage Neovim plugins (and more!) with Nix and Home Manager

Highly extensible software like Emacs, Vim, and Neovim tend to grow their own package managers. A software developer, for example, might want to install editor plugins that hook into a particular programming language's linter or language server. The programmer's text editor is therefore extended to support managing additional software to extend the text editor. If this loop continues for too long, the programmer's editor becomes more delicate and complex. The remedy for this problem is to manage software using dedicated tools apart
