| 5 | +The **Source of Truth** for the ObjectStack Protocol. Contains strictly typed Zod schemas that define every aspect of the system. |
| 6 | + |
| 7 | +## Protocols |
| 8 | + |
| 9 | +- **System**: Manifests, Datasources, APIs. |
| 10 | +- **Data**: Objects, Fields, Validation Rules. |
| 11 | +- **UI**: Views, Layouts, Dashboards. |
| 12 | +- **Automation**: Flows, Workflows, Triggers. |
| 13 | +- **AI**: Agents, RAG Pipelines, Models, MCP Servers. |
| 14 | + |
| 15 | +## Usage |
| 16 | + |
| 17 | +**Recommended: Use `ObjectSchema.create()` with `Field.*` helpers for strict TypeScript validation:** |
| 18 | + |
| 19 | +```typescript |
| 20 | +import { ObjectSchema, Field } from '@objectstack/spec/data'; |
| 21 | + |
| 22 | +// Create a validated object definition with type checking |
| 23 | +export const Task = ObjectSchema.create({ |
| 24 | + name: 'task', |
| 25 | + label: 'Task', |
| 26 | + icon: 'check-square', |
| 27 | + |
| 28 | + fields: { |
| 29 | + title: Field.text({ |
| 30 | + label: 'Title', |
| 31 | + required: true, |
| 32 | + maxLength: 200, |
| 33 | + }), |
| 34 | + |
| 35 | + status: Field.select({ |
| 36 | + label: 'Status', |
| 37 | + options: [ |
| 38 | + { label: 'To Do', value: 'todo', default: true }, |
| 39 | + { label: 'In Progress', value: 'in_progress' }, |
| 40 | + { label: 'Done', value: 'done' }, |
| 41 | + ], |
| 42 | + }), |
| 43 | + }, |
| 44 | + |
| 45 | + enable: { |
| 46 | + trackHistory: true, |
| 47 | + apiEnabled: true, |
| 48 | + }, |
| 49 | +}); |
| 50 | +``` |
| 51 | + |
| 52 | +**Alternative: Runtime validation of existing objects:** |
| 53 | + |
| 54 | +```typescript |
| 55 | +import { ObjectSchema } from '@objectstack/spec/data'; |
| 56 | + |
| 57 | +// Validate a JSON object against the schema |
| 58 | +const result = ObjectSchema.parse(myObjectDefinition); |
| 59 | +if (result.success) { |
| 60 | + console.log('Valid object:', result.data); |
| 61 | +} |
| 62 | +``` |
| 63 | + |
| 64 | +## MCP (Model Context Protocol) Integration |
| 65 | + |
| 66 | +Define MCP servers to connect AI agents to your ObjectStack data and tools: |
| 67 | + |
| 68 | +```typescript |
| 69 | +import { MCPServerConfigSchema } from '@objectstack/spec/ai'; |
| 70 | + |
| 71 | +// Define an MCP server exposing ObjectStack data |
| 72 | +export const objectStackMCP = MCPServerConfigSchema.parse({ |
| 73 | + name: 'objectstack_mcp', |
| 74 | + label: 'ObjectStack MCP Server', |
| 75 | + description: 'Connects AI agents to ObjectStack data and workflows', |
