Katalyst is an open-source project for creating containerized, AI-first WordPress development environments. It provisions WordPress inside Docker, installs and configures Agent Connector, and connects your AI agent to the site over MCP, so agents can work against a local install without touching the rest of your machine.

To create a local WordPress site with Oxygen installed and your AI agent connected, run:

npm create oxygen-wp@latest

Requirements. Two things must be installed before you run the command:

• Docker Desktop — the environment runs in a container.
• Node.js — runs the create command.

What the command does. It provisions a WordPress install inside Docker, installs Oxygen, and connects your AI agent — Claude Code, Codex, OpenCode, or any other agent supported by Katalyst. When it finishes, the site is running locally and your agent is ready to build.

Building with your agent. Ask for pages, posts, templates, and layouts. Everything the agent builds is real WordPress, editable in Oxygen.

Sandboxing. The agent works against the containerized install, so autonomous workflows stay isolated from your local machine.
