CTX vs mcp-nixos

CTX: CTX is a local context runtime for OpenCode and AI coding agents. It reduces token waste by indexing repositories, storing reusable guidance as graph memory, and providing compact task packs, read-cache compression, command pruning, and a live right-sidebar dashboard. It integrates natively with OpenCode as a context layer without replacing the agent launcher.; mcp-nixos: MCP-NixOS is an MCP server that provides real-time, accurate information about NixOS packages, options, Home Manager, nix-darwin, and more. It works on any system without requiring Nix, using just two tools to query multiple sources.
