Exposed MCP Tools (2)

safe

nix

A unified tool to query NixOS packages, options, flakes, and related information.

Primarily read-only operations; 'flake-inputs' requires caution but is still read-only.

safe

nix_versions

Retrieves historical package versions and metadata from NixHub.

Read-only access to package version information.

Safety Assessment

This MCP server is generally safe for AI use, as it primarily provides read-only access to NixOS ecosystem data. The 'flake-inputs' action requires caution, as it can expose local file contents if used improperly. Ensure proper query scoping to avoid information overload.

Primarily read-only access to NixOS package data.
No direct system modification capabilities.
Queries information about packages, options, and configurations.
Limited execution capabilities, focused on querying data.

Access to local flake inputs requires Nix installation, potentially exposing local configurations.
Internet access required for most data sources (FlakeHub, NixHub, etc.).
Potential for information overload if queries are too broad.
Incorrect usage of flake-inputs could expose sensitive file contents.
