Usage

Using the Overlay (Recommended)

Add this flake to your inputs and apply the overlay:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    mcp-servers.url = "git+ssh://gitea@gitea.bueso.eu/luis/mcp-servers";
  };

  outputs = { self, nixpkgs, ... }: {
    # Apply the overlay to get packages in pkgs
    nixosConfigurations.myhost = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        {
          nixpkgs.overlays = [ mcp-servers.overlays.default ];
        }
        # Now you can use pkgs.manim-mcp-server
      ];
    };
  };
}

Using Packages Directly

Access packages without the overlay:

{
  mcp-servers.url = "git+ssh://gitea@gitea.bueso.eu/luis/mcp-servers";

  outputs = { mcp-servers, ... }: {
    # Access directly
    myPackage = mcp-servers.packages.x86_64-linux.manim-mcp-server;
  };
}
