Installation

The fastest install is two commands on the machine you want to serve:

pip install cptr
cptr run

That path (including uvx cptr@latest run if you prefer uv) is covered step by step in the quickstart. This section covers everything else:

You want	Go to
Install with pip or uv on the machine itself	Quickstart
Run in a container (compose, named volumes, project mounts)	Docker
Install on a Windows machine	Windows
Install on a host with no internet access	Air-gapped
Upgrade an existing install	Updating

Requirements

Python 3.10 or newer (not needed for Docker)
macOS, Linux, or Windows
A browser, on the same machine or any other device

Optional feature groups install as pip extras: cptr[mcp] for MCP tool servers, cptr[pam] for PAM auth, or cptr[all] for everything. The Docker image already includes all of them.
