Multi-agent Collaboration Protocol Suites Architecture

This document defines a protocol suite and architectural framework for secure and scalable multi-agent collaboration. The proposed Multi-Agent Collaboration Protocol (MACP) enables trusted agent onboarding, capability-based discovery, distributed capability synchronization, and secure interaction among agents and external resources. The architecture introduces key entities such as the Agent Management Center (AMC), Agent Gateway (AGW), Agents, and External Resource Services (ERS), along with a set of protocols that collectively support dynamic, capability-driven collaboration across administrative domains.
