# clp-mcp Nix Package
## Installation
### Using nix-env
```bash
nix-env -iA nixpkgs.clp-mcp
```
### Using nix profile (Nix 2.4+)
```bash
nix profile install github:${{ github.repository_owner }}/clp-mcp
```
### Using flakes in configuration.nix
```nix
{
inputs.clp-mcp.url = "github:${{ github.repository_owner }}/clp-mcp";
# In your configuration
environment.systemPackages = [
inputs.clp-mcp.packages.${system}.default
];
}
```
### Using nix shell (temporary)
```bash
nix shell github:${{ github.repository_owner }}/clp-mcp
```
### Using nix run (one-off execution)
```bash
nix run github:${{ github.repository_owner }}/clp-mcp
```
