WHAT IT CONNECTS

mcp-neovim-server 为 AI Agent 提供什么

• Connects to your nvim instance if you expose a socket file, for example `--listen /tmp/nvim`, when starting nvim
• Views your current buffers
• Gets cursor location, mode, file name
• Runs vim commands and optionally shell commands through vim
• Can make edits using insert or replacement
• `nvim://session`: Current neovim text editor session
• `nvim://buffers`: List of all open buffers in the current Neovim session with metadata including modified status, syntax, and window IDs
• **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 through `nvim.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 cursor position, mode, filename, visual selection, window layout, current tab, marks, registers, and working directory
• **vim_edit**
• Edit lines using insert, replace, or replaceAll in the VIM editor
• Input `startLine` (number), `mode` (`"insert"` | `"replace"` | `"replaceAll"`), `lines` (string)
• insert will insert lines at startLine
• replace will replace lines starting at startLine
• replaceAll will replace the entire buffer contents
• **vim_window**
• Manipulate Neovim windows (split, vsplit, close, navigate)
• Input `command` (string: "split", "vsplit", "only", "close", "wincmd h/j/k/l")
• Allows window management operations
• **vim_mark**
• Set a mark at a specific position
• Input `mark` (string: a-z), `line` (number), `column` (number)
• Sets named marks at specified positions
• **vim_register**
• Set content of a register
• Input `register` (string: a-z or "), `content` (string)
• Manages register contents
• **vim_visual**
• Make a visual selection
• Input `startLine` (number), `startColumn` (number), `endLine` (number), `endColumn` (number)
• Creates visual mode selections
• This is a quick proof of concept to experiment with Model Context Protocol. Use at your own risk.
• May not interact well with a custom neovim config!
• Error handling could be better.
• Sometimes Claude doesn't get the vim command input just right.
• `ALLOW_SHELL_COMMANDS`: Set to 'true' to enable shell command execution (e.g. `!ls`). Defaults to false for security.
• `NVIM_SOCKET_PATH`: Set to the path of your Neovim socket. Defaults to '/tmp/nvim' if not specified.
