If you are a Nix user seeking AI assistance for infrastructure, choose MCP-NixOS for its real-time, free data. If you are an enterprise building RAG on domain-specific documents (finance, legal), choose Voyage AI for its specialized embeddings and compliance features. They solve entirely different problems — your pick depends on your ecosystem.
