MCP.Pizza Chef: bigcodegen

Start Neovim with a listening socket and your assistant gains nineteen editing tools. It can see your open files, know where the cursor sits, run ordinary Vim commands, insert or replace lines, find and replace with patterns, search the whole project, record macros, and manage tabs, folds, and windows. Nothing leaves your computer, because it talks to the editor already running in front of you. Note that no code has landed since September 2025, so the project has gone quiet, though it is not archived.

README

Neovim MCP Server

Connect Claude Desktop (or any Model Context Protocol client) to Neovim using MCP and the official neovim/node-client JavaScript library. This server leverages Vim's native text editing commands and workflows, which Claude already understands, to create a lightweight code or general purpose AI text assistance layer.

mcp-neovim-server FAQ

Is it still being updated?
Not lately. The last code change was September 2025. It still works and has not been archived, but the pace has slowed to a stop.
Does it work with regular Vim?
No. It needs Neovim started with a listening socket, so plain Vim will not work.
Which apps can use it?
Claude Desktop is the documented one; any app that supports MCP connections should also work.
Do I need a key or an account?
No. It talks to the editor already running on your own computer.
How hard is setup?
Easy. Drag the packaged file onto Claude Desktop, or paste a short snippet into its settings file.
Can I use this to have my assistant edit a file I already have open?
Yes. It writes into your live editing session rather than into a separate copy.
Can it run terminal commands?
Only if you switch that on. It is disabled by default for safety.
