Neovim

You connect Claude Desktop to Neovim using the MCP Neovim Server to leverage Neovim’s editing capabilities with AI assistance. This server exposes Neovim features like buffer management, cursor info, and command execution through MCP, enabling smooth, context-aware interactions with your editor.

How to use

You can use the MCP Neovim Server to peek into your Neovim session, switch buffers, inspect cursor state, and perform edits or searches directly from Claude Desktop or any Model Context Protocol client. Typical workflows include opening files, navigating buffers, creating or adjusting selections, running vim commands, and performing project-wide searches. Use the available MCP tools to edit buffers, manage windows and tabs, run macros, and perform sophisticated search and replace operations.

How to install

Prerequisites: you need Node.js and npm or npx available on your system. Ensure Neovim is running with a socket exposed, for example by starting Neovim with --listen /tmp/nvim.

Option 1: DXT Package (Recommended) install steps

• Download the latest .dxt file from the available releases
• Drag the file to Claude Desktop and follow any prompts to install the MCP Neovim Server package

Option 2: Manual Installation
- Add the following to your claude_desktop_config.json to run the MCP Neovim Server via npx

{
  "mcpServers": {
    "MCP Neovim Server": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-neovim-server"
      ],
      "env": {
        "ALLOW_SHELL_COMMANDS": "true",
        "NVIM_SOCKET_PATH": "/tmp/nvim"
      }
    }
  }
}

Additional setup notes

Shell commands are disabled by default for security. If you explicitly enable them, you can execute shell commands via the editor commands using the MCP tools that support shell execution when ALLOW_SHELL_COMMANDS is set to true.
