Frequently Asked Questions

What is MCP Nixos?

MCP server providing accurate information about NixOS packages, system options, Home Manager configurations, and nix-darwin macOS settings to prevent AI hallucinations.

Is MCP Nixos safe to use?

We cannot tell you that, and nobody scanning at this scale can. What we did in March 2026 was shallow-clone MCP Nixos and run five keyword searches over its source: auth identifiers, CORS configuration, rate-limit identifiers, the dependency manifest against a hardcoded list of 18 known-vulnerable packages, and unguarded eval/exec calls. At least one matched — the specific finding is in the scan report on this page. A text search cannot follow a variable, judge intent, or tell you what a server does once it is running, so "nothing matched" is not "safe". What the scan does and does not cover is written out at /mcp/security.

What are alternatives to MCP Nixos?

Similar MCP servers include Figma Context MCP, Git MCP, Firebase MCP. Each serves a similar purpose but may differ in features, language, and compatibility.
