nvim-mcp vs pfc-mcp

nvim-mcp: nvim-mcp provides an MCP server that connects to a running Neovim session via its native msgpack-RPC socket, enabling AI agents to see the editor state, edit buffers in memory, run Vim commands, send keystrokes, query LSP diagnostics, and more. It works with Cursor, Claude Code, Codex, and other MCP-compatible clients. The tool is designed for safe, non-destructive operations with full undo support.; pfc-mcp: pfc-mcp connects AI agents to ITASCA PFC through the Model Context Protocol. It provides tools for browsing PFC documentation and executing simulations via natural conversation. The project supports multiple PFC versions and works with various MCP clients.
