Open Protocols for Agent Interoperability Part 1: Inter-Agent Communication on MCP

AWS is exploring open protocols for inter-agent communication, focusing on the Model Context Protocol (MCP) as a standard for connecting generative AI agents. Key highlights include:

• AWS joining the MCP steering committee to support open standards
• Developing Strands Agents, an open source SDK for building AI agents
• Collaborating with companies like Anthropic, Google, Confluent, and CrewAI
• MCP enables flexible agent communication through:
  • Streamable HTTP for communication patterns
  • Capability discovery and negotiation
  • Secure authentication
  • Context sharing mechanisms

The blog demonstrates an example of inter-agent communication using Java and Spring AI, and outlines future enhancements to MCP like human-in-the-loop interactions and asynchronous communication.
