What is Xium OS?

Xium OS (XOS) is an AI-first enterprise data system. It connects structured business data with an AI assistant — without traditional GUI development.

The Idea

Traditional business software separates data, interface, and logic into distinct layers. XOS inverts this principle: the AI is the interface. The user describes what they want to see or do — XOS handles the rest.

Core Principles

Contexts instead of Screens
Data lives in so-called Contexts. A Context describes a data entity (e.g. person, order) as XML — with fields, types, relations and display rules. XOS automatically generates GraphQL queries and HTML views from this definition.

MCP as the Backbone
XOS implements the Model Context Protocol (MCP). Claude Desktop (or any other MCP client) connects to XOS and receives a defined set of tools: load, display, edit, and save data.

AI Workflow — No Direct Writes
Data changes always follow a three-step workflow:

xos_query — load data and display it in the Board
xos_ui_change_required — show AI changes as a preview
xos_ui_save — user confirms, data is saved

No direct database writes without user confirmation.

Components

Component	Description
XOS	Main process — MCP server, HTTP login, HTTPS dashboard, Board rendering
XOSP (Plugin Server)	Separate MCP server for data sources and GraphQL
mcp-bridge	stdio→MCP HTTP Streamable proxy for Claude Desktop
DSL	XML-based Context definition
Board	Browser-based display surface (HTTPS)

Technology Stack

Go — server and MCP bridge
Browser-based — HTTP login → Keycloak → HTTPS dashboard
GraphQL — automatically generated from DSL
HTML Templates — data binding via field=, loop=, bind= attributes
OpenBao — secret management (Vault-compatible fork, MPL 2.0)
etcd — central configuration source
OAuth 2.0 / OIDC — authentication via Keycloak
