# mcp-servers-nix
A Nix-based configuration framework for Model Control Protocol (MCP) servers with ready-to-use packages.
## Overview
This repository provides both MCP server packages and a Nix framework for configuring and deploying MCP servers. It offers a modular approach to configuring various MCP servers with a consistent interface.
## Features
- **Modular Configuration**: Define and combine multiple MCP server configurations
- **Reproducible Builds**: Leverage Nix for reproducible and declarative server setups
- **Pre-configured Modules**: Ready-to-use configurations for popular MCP server types
- **Security-focused**: Better handling credentials and sensitive information through `envFile` and `passwordCommand`, with pinned server versions
- **Framework Support**: Integrates with [Flakes](docs/module-usage.md#using-flakes), [flake-parts](docs/module-usage.md#using-flake-parts), [devenv](docs/module-usage.md#using-devenv), and [Home Manager](docs/module-usage.md#using-home-manager)
## Quick Start
Run an MCP server directly:
```bash
nix run github:natsukium/mcp-servers-nix#mcp-server-fetch
```
Generate a configuration file with `mkConfig`:
```nix
# config.nix
let
pkgs = import <nixpkgs> { };
mcp-servers-nix = import (fetchTarball
"https://github.com/natsukium/mcp-servers-nix/archive/main.tar.gz") { inherit pkgs; };
in
mcp-servers-nix.lib.mkConfig pkgs {
programs.filesystem = {
enable = true;
args = [ "/path/to/allowed/directory" ];
};
}
```
```bash
nix-build config.nix && cat result
```
```json
{
"mcpServers": {
"filesystem": {
"command": "/nix/store/7b4ancp3cns9lkkybd090qzr0hah5qq0-mcp-server-filesystem-2025.12.18/bin/mcp-server-filesystem",
"args": [ "/path/to/allowed/directory" ]
}
}
}
```
The output format adapts to the `flavor` option — see [Supported Flavors](#supported-flavors) below.
