claudecode.nvim

claudecode.nvim

The first Neovim IDE integration for Claude Code — bringing Anthropic's AI coding assistant to your favorite editor with a pure Lua implementation.
🎯 TL;DR: When Anthropic released Claude Code with VS Code and JetBrains support, I reverse-engineered their extension and built this Neovim plugin. This plugin implements the same WebSocket-based MCP protocol, giving Neovim users the same AI-powered coding experience.

What Makes This Special

When Anthropic released Claude Code, they only supported VS Code and JetBrains. As a Neovim user, I wanted the same experience — so I reverse-engineered their extension and built this.

- 🚀 Pure Lua, Zero Dependencies — Built entirely with vim.loop and Neovim built-ins
- 🔌 100% Protocol Compatible — Same WebSocket MCP implementation as official extensions
- 🎓 Fully Documented Protocol — Learn how to build your own integrations (see PROTOCOL.md)
- ⚡ First to Market — Beat Anthropic to releasing Neovim support
- 🛠️ Built with AI — Used Claude to reverse-engineer Claude's own protocol

Installation

That's it! The plugin will auto-configure everything else.
Lazy-loading: with this spec the plugin loads on first use — when a listed
cmd is run or a mapped key is pressed — not at startup. The cmd list is what
makes :ClaudeCode (and the other commands below) available before any keymap is
pressed. If you would rather load the plugin eagerly at startup, set lazy = false
(the cmd/keys triggers then become optional).

Requirements

- Neovim >= 0.8.0
- Claude Code CLI installed
- folke/snacks.nvim for enhanced terminal support

Local Installation Configuration

If you've used Claude Code's migrate-installer command to move to a local installation, you'll need to configure the plugin to use the local path.
