Install

Via Arquestra Runner (recommended — automatic)

If you have the Arquestra Runner installed:

arquestra-runner configure-mcp --agent all

This registers the plugin automatically. On first use, Claude Code opens https://apertura-ai.de/oauth/connect in your browser. If you are already signed into your Arquestra account there, authorization completes instantly with no extra steps. If not, sign in once and you are done.

Via Claude Code Plugin Manager (manual fallback)

1. Open Manage Plugins → Install by GitHub URL
2. Enter: https://github.com/Apertura-AI/arquestra-claude-plugin
3. Click Install
4. On first use, Claude Code opens https://apertura-ai.de/oauth/connect — sign in if not already authenticated.
