description: First Resonance builds ION, a modern Factory Operating System (MES) for companies manufacturing complex hardware
  in aerospace, defense, robotics, medical devices, and clean energy. ION provides digital work instructions (Procedures and
  Runs), part and inventory traceability, mBOM/aBOM management, quality and compliance workflows, production scheduling (ION
  AutoPlan), and analytics. For developers, ION exposes a GraphQL API (api.buildwithion.com) secured with OAuth 2.0 client-credentials
  API keys, cursor-based (Relay) pagination, webhook subscriptions for realtime events, and a beta hosted MCP server so AI
  agents can operate the factory system. This profile was enriched from First Resonance's public developer manual.
