cursor-tab.nvim

⚠️ Experimental - Very loosely tested, under active development. Use at your own risk.

Brings Cursor's AI-powered tab completion to Neovim. Get code suggestions as you type and accept them with Tab, just like in Cursor IDE.

Requirements

System:

• macOS only (reads Cursor's auth from macOS-specific paths)
• curl (for HTTP requests and binary download)
• sqlite3 (to read Cursor credentials)

Critical:

• Cursor IDE must be installed at /Applications/Cursor.app
• You must be signed into Cursor (plugin reads your auth token automatically)

Without Cursor installed and authenticated, the plugin won't work.

Installation

lazy.nvim

{
  "bengu3/cursor-tab.nvim",
  config = function()
    require("cursor-tab").setup()
  end,
}

The plugin will automatically download the appropriate binary for your platform on first run.

packer.nvim

use {
  "bengu3/cursor-tab.nvim",
  config = function()
    require("cursor-tab").setup()
  end
}

vim-plug

Plug 'bengu3/cursor-tab.nvim'

Add to init.lua:

require("cursor-tab").setup()

Manual Binary Installation

If auto-download fails, you can manually install:

1. Download the binary for your platform from Releases
2. Place it at ~/.local/share/nvim/lazy/cursor-tab.nvim/bin/cursor-tab-server (or equivalent path for your plugin manager)
3. Make it executable: chmod +x path/to/cursor-tab-server

Or run :CursorTabInstall in Neovim to retry auto-installation.

Custom Server Path (Optional)

require("cursor-tab").setup({
  server_path = "/custom/path/to/cursor-tab-server"
})

Building from Source (Optional)

If you prefer to build from source:

# Requirements: Go 1.21+, buf CLI, make
git clone https://github.com/bengu3/cursor-tab.nvim ~/.config/nvim/pack/plugins/start/cursor-tab.nvim
cd ~/.config/nvim/pack/plugins/start/cursor-tab.nvim
make build

Config
