Allows executing commands in ephemeral containers with any combination of Nix packages from the NixOS/nixpkgs repository.

1. Click on "Install Server".

2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.

3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@zeughaus-mcp run python3 and curl to fetch https://example.com"

That's it! The server will respond to your query, and you can continue using it as needed.

Here is a step-by-step guide with screenshots.
