# MCP-NixOS - Because Your AI Shouldn't Hallucinate Package Names

## Quick Start
**🚨 No Nix/NixOS Required!** Works on any system - Windows, macOS, Linux. You're just querying APIs.
### Option 1: uvx (Recommended)
[](https://cursor.com/install-mcp?name=nixos&config=eyJjb21tYW5kIjoidXZ4IG1jcC1uaXhvcyJ9)
```json
{
"mcpServers": {
"nixos": {
"command": "uvx",
"args": ["mcp-nixos"]
}
}
}
```
### Option 2: Nix
[](https://cursor.com/install-mcp?name=nixos&config=eyJjb21tYW5kIjoibml4IHJ1biBnaXRodWI6dXRlbnNpbHMvbWNwLW5peG9zIC0tIn0%3D)
```json
{
"mcpServers": {
"nixos": {
"command": "nix",
"args": ["run", "github:utensils/mcp-nixos", "--"]
}
}
}
```
### Option 3: Docker
[](https://cursor.com/install-mcp?name=nixos&config=eyJjb21tYW5kIjoiZG9ja2VyIiwiYXJncyI6WyJydW4iLCItLXJtIiwiLWkiLCJnaGNyLmlvL3V0ZW5zaWxzL21jcC1uaXhvcyJdfQ%3D%3D)
```json
{
"mcpServers": {
"nixos": {
"command": "docker",
"args": ["run", "--rm", "-i", "ghcr.io/utensils/mcp-nixos"]
}
}
}
```
Your AI now has access to real NixOS data instead of making things up. You're welcome.
### Option 4: HTTP (Remote MCP)
FastMCP supports running this server over HTTP at a URL (the MCP endpoint defaults to `/mcp`).
```bash
# Run an HTTP MCP server at http://127.0.0.1:8000/mcp
MCP_NIXOS_TRANSPORT=http MCP_NIXOS_HOST=127.0.0.1 MCP_NIXOS_PORT=8000 mcp-nixos
```
STDIO (default):
```bash
MCP_NIXOS_TRANSPORT=stdio mcp-nixos
```
Custom path:
```bash
MCP_NIXOS_TRANSPORT=http MCP_NIXOS_PATH=/api/mcp mcp-nixos
```
Stateless HTTP (disables per-client session state):
```bash
MCP_NIXOS_TRANSPORT=http MCP_NIXOS_STATELESS_HTTP=1 mcp-nixos
```
### Option 5: Pi Coding Agent
[Pi](https://www.npmjs.com/package/@mariozechner/pi-coding-agent) does not speak MCP natively. Two supported paths:
**A. pi-mcp-adapter (recommended — speaks MCP, single source of truth):**
```bash
pi install npm:pi-mcp-adapter
```
Then add to `~/.pi/agent/mcp.json`:
```json
{
"mcpServers": {
"nixos": {
"command": "uvx",
"args": ["mcp-nixos"],
"lifecycle": "lazy"
}
}
}
```
**B. Project-local extension (clone + run):** this repo ships `.pi/extensions/mcp-nixos.ts`, auto-loaded when you run `pi` in the cloned repo. Optional: `cd .pi && npm install` for editor type resolution. Pi runs it either way.
## What Is This?
An MCP server providing accurate, real-time information about:
- **NixOS packages** - 130K+ packages that actually exist
- **NixOS options** - 23K+ ways to configure your system
- **Home Manager** - 5K+ options for dotfile enthusiasts
- **nix-darwin** - 1K+ macOSExcerpt of 12,255 characters
