Overview

When deployed on Docker, Brainy exposes multiple API interfaces on a single port (default: 3000):

# What gets exposed on port 3000:
- REST API        # HTTP/HTTPS endpoints
- WebSocket       # Real-time bidirectional communication
- MCP Interface   # Model Control Protocol for AI models
- GraphQL         # Optional GraphQL endpoint
- Metrics         # Prometheus metrics endpoint

WebSocket API

Real-time Connection

// server.ts - WebSocket setup
import { Server } from 'socket.io'

const io = new Server(server, {
  cors: {
    origin: '*',
    methods: ['GET', 'POST']
  }
})

io.on('connection', (socket) => {
  console.log('Client connected:', socket.id)
  
  // Real-time data operations
  socket.on('add', async (data, callback) => {
    try {
      const id = await brainy.add(data.content, data.metadata)
      callback({ success: true, id })
      
      // Broadcast to all clients
      io.emit('data:added', { id, timestamp: new Date() })
    } catch (error) {
      callback({ success: false, error: error.message })
    }
  })
  
  // Real-time search
  socket.on('search', async (query, callback) => {
    const results = await brainy.search(query.text, query.options)
    callback({ success: true, results })
  })
  
  // Cortex commands
  socket.on('cortex:command', async (command, callback) => {
    const result = await executeCortexCommand(command)
    callback({ success: true, result })
  })
  
  // Subscribe to augmentation events
  socket.on('subscribe:augmentations', () => {
    socket.join('augmentation-events')
  })
  
  // Real-time augmentation notifications
  brainy.on('augmentation:triggered', (data) => {
    io.to('augmentation-events').emit('augmentation:triggered', data)
  })
  
  brainy.on('augmentation:complete', (data) => {
    io.to('augmentation-events').emit('augmentation:complete', data)
  })
  
  socket.on('disconnect', () => {
    console.log('Client disconnected:', socket.id)
  })
})

Client Connection Examples

// JavaScript/TypeScript Client
import io from 'socket.io-client'

const socket = io('http://brainy-server:3000')

// Add data
socket.emit('add', {
  content: 'John works at Acme Corp',
  metadata: { source: 'web-app' }
}, (response) => {
  console.log('Added:', response.id)
})

// Subscribe to events
socket.on('data:added', (data) => {
  console.log('New data added:', data)
})

socket.on('augmentation:complete', (data) => {
  console.log('Augmentation complete:', data)
})

# Python Client
import socketio

sio = socketio.Client()

@sio.on('connect')
def on_connect():
    print('Connected to Brainy')
    
@sio.on('data:added')
def on_data_added(data):
    print(f"New data: {data['id']}")

sio.connect('http://brainy-server:3000')
sio.emit('add', {'content': 'Test data'})

MCP Interface

Model Control Protocol for AI Integration

MCP allows AI models (like Claude, GPT, etc.) to access Brainy's data and use augmentations as tools.

// server.ts - MCP Interface setup
import { BrainyMCPService } from '@soulcraft/brainy'

// Initialize MCP Service
const mcpService = new BrainyMCPService(brainy, {
  port: 3001, // Optional separate port, or use same as REST
  enableWebSocket: true,
  enableREST: true
})

// Start MCP server
await mcpService.start()

// Or add MCP to existing Express app
app.use('/mcp', mcpService.getExpressMiddleware())

// WebSocket MCP
io.on('connection', (socket) => {
  socket.on('mcp:request', async (request, callback) => {
    const response = await mcpService.handleMCPRequest(request)
    callback(response)
  })
})

Authentication & Security

API Key Authentication

JWT Authentication

// For user-facing applications
import jwt from 'jsonwebtoken'

Rate Limiting

import rateLimit from 'express-rate-limit'

// General rate limit
const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
})

// Stricter limit for expensive operations
const searchLimiter = rateLimit({
  windowMs: 1 * 60 * 1000, // 1 minute
  max: 10 // 10 searches per minute
})

app.use('/api', limiter)
app.use('/api/v1/search', searchLimiter)

Summary

When deployed on Docker, Brainy exposes:

1. REST API - Full CRUD operations, graph traversal, augmentation management
2. WebSocket - Real-time bidirectional communication
3. MCP Interface - AI model integration with augmentations as tools
4. GraphQL - Optional query language support
5. Metrics - Prometheus-compatible monitoring

All accessible through a single Docker container on configurable ports, with:

• Authentication options (API keys, JWT, mTLS)
• Rate limiting for protection
• Load balancing support
• Language-agnostic client access
• Full observability with metrics and health checks

This makes Brainy a complete API platform that any service can connect to and use! 🧠⚛️
