NixOS Configuration CI / Nix Flake Check (pull_request) Successful in 25s
Both come from the build, and both were non-obvious: - fetchzip hashes the *unpacked* tree, not the .tgz bytes, so a hash computed from the published tarball does not match; the derivation reports the NAR hash of the extracted contents instead. - npmDepsHash only exists once npm has materialised the dependency tree from the committed lockfile. Verified with nix build .#romm-mcp: the derivation builds and ./result/bin/romm-mcp starts and prints 'RomM MCP server running on stdio'.

Home Manager Modules
The flake also exports reusable Home Manager modules:
home-manager.sharedModules = [
mcp-servers.homeManagerModules.mcp-gateway
mcp-servers.homeManagerModules.ssh-mcp
];
services.mcp-gatewayrendersgateway.yamlfrom Nix options.services.ssh-mcp.instances.<name>renders per-instancehosts.tomlandknown_hostsfiles and exposes agatewayBackendhelper.
See docs/mcp-gateway.md and docs/ssh-mcp.md.
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;
};
}
