A2A Connector - Mule 4

Anypoint Connector for Agent2Agent (A2A) (A2A Connector) facilitates inter-agent communication for Large Language Model (LLM) agents and other applications by implementing the A2A protocol. The A2A protocol is an open standard that supports:

• Capability discovery
• Identifies the functions and services offered by agents
• Interaction negotiation
• Establishes communication methods between agents.
• Secure information exchange
• Transmits data between agent systems without requiring direct internal access.

This enables agents to interact and delegate specialized tasks to other agents. The A2A Connector provides Mule app integration that functions as both A2A servers and A2A clients.
