AI tooling

Every AI coding tool, packaged. Claude Code, Gemini CLI, Copilot, MLX modules, 15+ MCP servers — declarative, reproducible, version-pinned.

The whole AI toolkit, in one flake. nix run and go.

nix-ai is the package and config layer for everything AI-coding-related. It packages CLIs that don’t yet have first-party Nix derivations, pins MCP server versions, and exports overlays the rest of the Nix stack consumes.

What it does

• Packages Claude Code, Gemini CLI, GitHub Copilot CLI, and assorted AI tooling
• Provides MLX module derivations for Apple Silicon
• Pins 15+ MCP servers and exposes them as reusable Nix attributes
• Exports an overlay so nix-darwin and nix-home can include AI tools without duplicating logic
• Includes a shell module (devShells.default) for “just give me an AI sandbox” workflows

How it fits

Feeds into	Consumes
macOS host overlay, User environment packages, ad-hoc nix shell	ai-assistant-instructions rule set

Getting started

1. Try a single tool

   nix run github:JacobPEvans/nix-ai#claude-code -- --help. No clone needed.

2. Enter the sandbox shell

   nix develop github:JacobPEvans/nix-ai drops you into a shell with every AI CLI on PATH.

3. Import into nix-darwin

   Add nix-ai as a flake input, then include nix-ai.overlays.default in your nixpkgs config. The README has the boilerplate.
