A proof of concept integration between Claude Desktop and Neovim using Model Context Protocol (MCP) and the official neovim/node-client JavaScript library.
The Neovim MCP Server is a demonstration of integrating Claude Desktop with Neovim through the Model Context Protocol (MCP). This integration utilizes the neovim/node-client JavaScript library to create a lightweight code assistance layer that leverages Vim's native text editing commands and workflows. By connecting to a Neovim instance, the server can view the current buffer, get cursor location, mode, and file name, run Vim commands, and make edits using insert or replacement. This setup allows for a seamless interaction between Claude and Neovim, providing a unique code editing experience. However, as a proof of concept, it comes with limitations such as potential issues with custom Neovim configurations, socket connection handling, and error management. Despite these challenges, the Neovim MCP Server offers a glimpse into the potential of MCP in enhancing code editing workflows.
Features
- Connects to your nvim instance if you expose `--listen /tmp/nvim` when starting nvim
- Views your current buffer
- Gets cursor location, mode, file name
- Runs vim commands
- Can make edits using insert or replacement
Tools
vim_buffer
Current VIM text editor buffer with line numbers shown. Input
filename(string). Filename is ignored, returns a string of numbered lines with the current active buffer content.vim_command
Send a command to VIM for navigation, spot editing, and line deletion. Input
command(string). Runs a vim command first passed throughnvim.replaceTermcodes. Multiple commands will work if separated by newlines. On error,'nvim:errmsg'contents are returned.vim_status
Get the status of the VIM editor. Status contains line, col, mode, filename, and visual selection.
