Agent-to-Agent (A2A) Protocols

Enable agents to discover, communicate, and collaborate across frameworks and systems.

The Interoperability Challenge

Different agent frameworks:

• LangChain/LangGraph
• AutoGen
• CrewAI
• Custom implementations

Problem: They can't talk to each other natively.

Solution: Standard protocols for agent communication.
