Usage

A WebUI that installs on both Claude Code and Codex — run both at once. After install, launch it from the CLI with one line:

• Claude → http://localhost:7878
• Codex → http://localhost:7979

Install

Claude Code

/plugin marketplace add https://github.com/MindLab-Research/macaron-artifacts
/plugin install macaron@macaron

Then open it in a session with /macaron.

Codex

codex plugin marketplace add https://github.com/MindLab-Research/macaron-artifacts
codex plugin add macaron@macaron

Then say open macaron web ui in a session to open it.

Without Installing the Plugin — One bunx Line

The published tarball ships the prebuilt server + web bundles and exposes two bins — mcc (Claude WebUI, port 7878) and mcx (Codex WebUI, port 7979). Launch either in one command:

bunx mcc@https://pkg.pr.new/mindverse-ltd/macaron-claude-code/mcc@<sha>   # Claude → http://localhost:7878
bunx mcx@https://pkg.pr.new/mindverse-ltd/macaron-claude-code/mcc@<sha>   # Codex  → http://localhost:7979

bunx resolves by bin name, so mcx@… boots the Codex launcher from the same mcc package. Replace <sha> with a commit on main. Both bins accept --host / --port; run --help for all flags.

Using It

Once inside the WebUI:

• Click a workspace in the sidebar to enter its canvas; pin a session with +
• On the canvas: drag the grip to reposition, pull the bottom-right corner to resize, click a tile to focus
• Input box: Enter sends · Shift+Enter for a newline · ↑/↓ cycles history · paste an image to attach it

On first use, the Codex side needs a Base URL / API Key / Model filled in under Settings.

Updating

Claude Code

/plugin update macaron

Codex

codex plugin marketplace upgrade macaron   # pull the latest version
codex plugin remove macaron@macaron
