Atomos Structura

High-performance visual schema designer and vector presentation engine for TypeScript projects. Build, edit, and export data-model schemas headlessly via API, through Model Context Protocol (MCP) tools for autonomous AI agents, or with a full interactive multi-canvas workspace UI.

---

Core Capabilities

• Headless API: Programmatically construct and manipulate schemas without mounting a browser DOM.
• AI Agent Integration: Full MCP server supporting Model Context Protocol for Claude, GPT, and Cursor.
• Meta Canvas Architecture: Multi-dimensional nested schema hierarchy with 3 operational modes (Single Canvas, Flat Multi-Canvas, and Hierarchical Meta Canvas).
• Standalone SVG Presentation Engine: High-fidelity vector rendering engine (@atomos-web/renderer-svg) supporting themes and 4 directional relationship modes.
• Mermaid.js Adapter: Bidirectional conversion between Mermaid flowchart DSL and Atomos Structura Schema Graphs.
• Multi-Instance Isolation: Complete workspace state separation via mandatory instanceId tracking.
• Code Export Adapters: Native code generators for SQL DDL, Prisma Schema, TypeScript Interfaces, JSON Schema, and Mermaid.js.

Workspace Operational Modes

Atomos Structura supports three distinct operational modes configurable per session or via MCP:

1. Mode 1 (Single Canvas): Embedded application default configuration. Renders a single active schema without tab UI or group palette.
2. Mode 2 (Multi-Canvas): Enables schema tabs for switching between multiple flat schema diagrams.
3. Mode 3 (Meta Canvas): Full hierarchical multi-dimensional mode. Enables group palette sidebar, nested SVG snapshot rendering for group entities, and parent-child breadcrumb navigation.

Quick Start

1. Headless Schema Construction

import { createSchemaBuilder } from '@atomos-web/structura';

const builder = createSchemaBuilder({
  config: { headless: true },
  instanceId: 'workspace-instance-1'
});

// Add Entity
builder.addEntity({
  id: 'usr_01',
  name: 'User',
  position: { x: 100, y: 100 },
  dimensions: { width: 220, height: 140 },
  properties: [
    { key: 'id', label: 'ID', dataType: 'UUID' },
    { key: 'email', label: 'Email', dataType: 'VARCHAR(255)' }
  ]
});

// Add Relationship
builder.addRelationship({
  id: 'rel_01',
  leftEntityId: 'usr_01',
  rightEntityId: 'ord_01',
  direction: 'right',
  leftCardinality: '1',
  rightCardinality: '*'
});

2. Standalone Vector Presentation Mode

import { renderToSVG } from '@atomos-web/renderer-svg';

const svgContent = renderToSVG(snapshot, {
  theme: 'sovereign-dark',
  padding: 30,
  responsive: true
});

3. AI Agent MCP Integration

# Launch MCP Server
npx @atomos-web/structura-mcp

AI agents connect via HTTP/SSE or stdio and execute tools such as:

• structura_set_workspace_mode
• structura_group_schema
• structura_auto_layout
• structura_export_svg
