Arquestra — Claude Code Plugin

Connects Claude Code to Arquestra by Apertura AI — an AI orchestration platform for scientific computing, computational chemistry, and HPC workflows.

MCP endpoint: https://api.apertura-ai.de/mcp/orchestration
Auth: OAuth 2.0 PKCE — sign in once with your Arquestra account, token stored for 90 days.

Install

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.
