# Agent-to-agent communication frameworks and authorization patterns emerge for multi-agent collaboration

New tooling is being developed to enable secure agent-to-agent (A2A) communication. A2acast provides multi-computer agent collaboration capabilities, Cardwall offers health checks and status badges for agent networks, and developers are implementing authorization patterns using Open Policy Agent (OPA) sidecar architecture for chain-aware AI agent access control. These frameworks address coordination and security requirements for decentralized multi-agent systems.
