Arquestra — Scientific Computing Orchestration

apertura-ai/arquestra-claude-plugin
authHTTPregistry active
Summary

Connects Claude to Arquestra's AI orchestration platform for running computational chemistry and HPC jobs. You get tools to create runs, poll status, fetch logs, list registered machines, and browse available domain packs. Auth is OAuth 2.0 PKCE with a 90-day token, handled automatically on first use. The recommended setup uses their arquestra-runner CLI to register the MCP endpoint across multiple agents at once. Useful when you're already working in the Arquestra ecosystem and want Claude to trigger jobs, check progress, or pull results without leaving the conversation.

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

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.

Available tools

ToolDescription
cloud_mcp_probeVerify cloud MCP connection
create_runStart a new run — returns run_id and enters the orchestration loop
list_runsList your runs, newest first
get_runGet status and details for a specific run
get_run_logsFetch current state and logs for a run
list_machinesList your registered runner machines
list_packsList available domain packs (chemistry, HPC, bioinformatics…)

Auth

OAuth 2.0 PKCE — the API exposes /.well-known/oauth-authorization-server. Claude Code handles the full login flow on first connection. No tokens to paste or manage. The 90-day access token is stored locally and renewed on expiry.


Other agents

For Codex CLI, Gemini CLI, VS Code, Cursor, and others — the runner covers them too:

arquestra-runner configure-mcp --agent all
