@objectstack/spec

The Source of Truth for the ObjectStack Protocol. Contains strictly typed Zod schemas that define every aspect of the system.

Protocols

• System: Manifests, Datasources, APIs.
• Data: Objects, Fields, Validation Rules.
• UI: Views, Layouts, Dashboards.
• Automation: Flows, Workflows, Triggers.
• AI: Agents, RAG Pipelines, Models, MCP Servers.

Usage

Recommended: Use ObjectSchema.create() with Field.* helpers for strict TypeScript validation:

import { ObjectSchema, Field } from '@objectstack/spec/data';

// Create a validated object definition with type checking
export const Task = ObjectSchema.create({
  name: 'task',
  label: 'Task',
  icon: 'check-square',
  
  fields: {
    title: Field.text({
      label: 'Title',
      required: true,
      maxLength: 200,
    }),
    
    status: Field.select({
      label: 'Status',
      options: [
        { label: 'To Do', value: 'todo', default: true },
        { label: 'In Progress', value: 'in_progress' },
        { label: 'Done', value: 'done' },
      ],
    }),
  },
  
  enable: {
    trackHistory: true,
    apiEnabled: true,
  },
});

Alternative: Runtime validation of existing objects:

import { ObjectSchema } from '@objectstack/spec/data';

// Validate a JSON object against the schema
const result = ObjectSchema.parse(myObjectDefinition);
if (result.success) {
  console.log('Valid object:', result.data);
}

MCP (Model Context Protocol) Integration

Define MCP servers to connect AI agents to your ObjectStack data and tools:

import { MCPServerConfigSchema } from '@objectstack/spec/ai';

// Define an MCP server exposing ObjectStack data
export const objectStackMCP = MCPServerConfigSchema.parse({
  name: 'objectstack_mcp',
  label: 'ObjectStack MCP Server',
