Nuclos for Developers and IT Teams

Open architecture, REST API, MCP integration, and AGPL licence.

This page is for IT leaders and developers evaluating Nuclos on technical merit. You will find the platform architecture and entry points for the REST API, rule engine, MCP, tooling, and operations.

  • Open Source · AGPL 3.0
  • REST API from data model
  • MCP integration
  • On-premise or cloud

Architecture at a Glance

Five layers from the metadata model to deployment: open, traceable, no black-box system.

  1. Metadata model

    Every object, field, relationship, and rule is defined as metadata. The data model is fully configurable, versioned, and forms the base for every layer above it.

  2. Low-code layer

    Screens, workflows, and business logic are built in the low-code editor on top of the metadata model. AI agents have no direct database access: the solution space stays within validated platform patterns.

  3. REST API

    Every modelled object automatically generates a consistent REST API: GET, POST, PUT, DELETE. One schema, directly testable, no manual endpoint maintenance.

  4. MCP integration

    MCP (Model Context Protocol) connects AI agents directly to the ERP system's processes and data. Agents can read, write, and trigger actions, within the boundaries of the low-code layer.

  5. Deployment

    Nuclos runs on-premise on your own infrastructure or in the Novabit Cloud (made and hosted in Germany). The source code stays under AGPL 3.0. No vendor dependency.
