# nix-ai

A Nix flake and home-manager module that declares an entire AI coding toolkit, Claude Code, Gemini, GitHub Copilot, OpenAI Codex, Cursor CLI, Qwen Code and a shared catalog of MCP servers, as reproducible configuration, rebuilding it identically on any supported machine.

nix-ai captures an AI coding setup, plugins, hooks, agents, commands, rules, permissions and MCP server catalogs across several tools, as Nix code instead of manual per-machine configuration, so one command reproduces the exact same setup on a new machine. It manages Claude Code's plugin ecosystem, Gemini and Antigravity CLI and IDE settings, GitHub Copilot configuration, OpenAI Codex settings and approval policy, a Cursor CLI terminal agent, Qwen Code and Cecli settings, a shared MCP server catalog such as GitHub, Terraform, Context7, filesystem and memory fanned out to every agent, other AI dev tools such as cclint and claude-flow, and, on macOS, local Apple Silicon inference through vllm-mlx.

Added as a flake input and a home-manager shared module, it evaluates with no extra configuration required, though local MLX inference stays idle until pointed at a model. Separate exported modules let a user pull in just one tool, such as Claude Code alone, just Codex, just the MCP catalog, or just Maestro orchestration, plus a pure settings-JSON export for CI validation and a role-name-to-model-ID registry for other tooling to reuse.

Built with Nix, requiring Nix with flakes and home-manager on aarch64-darwin or x86_64-linux. MIT licensed.
