Development

This project uses nix to manage a development environment that can be used on Linux and macOS.

Quick Start - Linux / macOS

  1. Install nix

  2. Enable nix flakes

sudo sh -c 'echo "experimental-features = nix-command flakes" >> /etc/nix/nix.conf'
  1. Enter dev shell
nix develop
  1. Build project
just build-release
  1. mcp-guardian and mcp-guardian-proxy are now in _build/bin/ which is in PATH of the dev shell.

Quick Start - Windows

  1. Install git with symlink support (otherwise you will need to restore ./mcp-guardian/bindings before building).

  2. Install rustup.

  3. Install nodejs.

  4. Install yarn.

npm install --global yarn

  1. Install .dll dependencies. The easiest way to do this is to install Visual Studio and install the C++ development packages.

cargo install just

  1. Enter repo root with git-bash (otherwise just won't work and you'll need to call cargo directly)

  2. Build project

just build-release
