MBC (Model Backend Controller) flips the MCP pattern: instead of AI calling your backend, your backend orchestrates AI agents as autonomous workers with tools.

Demo: 3 AI agents build a complete website in 34s for $0.34 — https://youtu.be/A_GiAqIWJxE

Features: multi-provider (Anthropic, OpenAI, OpenRouter), tools via PHP Attributes, multi-agent patterns (Pipeline, Orchestrator, Shared Memory), real-time WebSocket monitoring, REST API.
