NixOS Configuration CI / Nix Flake Check (pull_request) Successful in 15s
- sabnzbd-mcp: original upstream (jmagar/sabnzbd-mcp) was deleted from GitHub (404). Repoint to jasonpaulso/sabnzbd-mcp fork, which preserves the same file layout and the /sabnzbd/api string postPatch rewrites. - annas-mcp: remove package that was never completed (lib.fakeHash placeholders) and is not referenced anywhere in config-nixos. It was breaking 'nix flake check'.

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;
};
}
