Agentic protocols - AWS Prescriptive Guidance

Agentic protocols

AI agents require standardized communication protocols to interact with other agents and services. Organizations implementing agent architectures face significant challenges around interoperability, vendor independence, and future-proofing their investments.

This section helps you navigate the agent-to-agent protocol landscape with a focus on open standards that maximize flexibility and interoperability. (For information about agent-to-tool protocols, see Tool integration strategy later in this guide.)

This section highlights the Model Context Protocol (MCP), an open standard originally developed by Anthropic in 2024. Today, AWS actively supports MCP through contributions to the protocol's development and implementation. AWS is collaborating with leading open-source agent frameworks, including LangGraph, CrewAI, and LlamaIndex, to shape the future of inter-agent communication on the protocol. For more information, see Open Protocols for Agent Interoperability Part 1: Inter-Agent Communication on MCP (AWS Blog).
