/**
|
||||
* BrainyMCPBroadcast
|
||||
*
|
||||
* Enhanced MCP service with real-time WebSocket broadcasting capabilities
|
||||
* for multi-agent coordination (Jarvis ↔ Picasso communication)
|
||||
*
|
||||
* Features:
|
||||
* - WebSocket server for real-time push notifications
|
||||
* - Subscription management for multiple Claude instances
|
||||
* - Message broadcasting to all connected agents
|
||||
* - Works both locally and with cloud deployment
