The Harbor CLI gives you full control over your MCP server fleet from the terminal. Every command uses a nautical theme, with standard aliases available if you prefer.

​
Installation

curl -fsSL https://harbormcp.ai/install.sh | sh
On macOS, the install script installs the desktop app (which includes the CLI) and symlinks harbor to your PATH. Use HARBOR_NO_APP=1 for a CLI-only install. On Linux, it installs the harbor CLI binary directly. On Windows, the PowerShell script downloads and runs the MSI installer silently. You can also build from source: 
git clone https://github.com/JoshuaShunk/Harbor.git
cd Harbor
cargo install --path crates/harbor-cli

​
Usage

harbor <command> [options]
