Provides a server for accessing NixOS packages, system options, Home Manager, and nix-darwin configurations with multi-level caching and advanced search capabilities

MCP-NixOS provides a server for interacting with NixOS packages, system options, Home Manager configuration, and nix-darwin macOS configuration through standardized URL schemes. Developed by James Brink, this Python implementation features multi-level caching with filesystem persistence, detailed documentation integration, and support for advanced search capabilities including hierarchical paths and version filtering. The architecture separates concerns into cache, clients, contexts, resources, and tools components, making it ideal for developers seeking programmatic access to Nix ecosystem configuration options and package information through AI assistants.

Frequently asked questions

How do I install NixOS?

Add the install command above to your Claude Code, Cursor, or Windsurf MCP configuration. Most servers register via npx, a local command, or a Docker image. Refer to the source repository for environment variables and credential requirements.

Which clients support NixOS?

Any MCP-compatible client works: Claude Desktop, Claude Code CLI, Cursor, Windsurf, Zed, and VS Code with the official MCP extension. OpenAI Codex and GitHub Copilot increasingly support MCP via adapter bridges.

Is NixOS free?

The server itself is typically open source. Any upstream service (API keys, paid tiers, hosted infrastructure) may have its own pricing. Check the source repository for details.
