nvim-gemini-companion

Overview

This Neovim plugin provides a sophisticated integration with AI agents like Gemini and Qwen through the Model Context Protocol (MCP). Unlike traditional AI plugins, it's built around an MCP backend that maintains tight integration with the editor environment. The plugin features a customizable sidebar interface for AI interactions, supports multiple agents simultaneously, offers diff management for accepting or rejecting AI suggestions, and includes tmux integration for persistent sessions across editor restarts.
