"Amazon announced support for the Agent-to-Agent (A2A) protocol in Amazon Bedrock AgentCore Runtime, enabling communication between agents built on different frameworks. The protocol allows agents developed with Strands Agents, OpenAI Agents SDK, LangGraph, Google ADK, or Claude Agents SDK to "share context, capabilities, and reasoning in a common, verifiable format." Bedrock AgentCore Runtime serves as the infrastructure layer that processes these inter-agent communications. The A2A protocol introduces interoperability across multi-agent systems, allowing developers to compose workflows that span different agent frameworks."
"Agentic systems require several foundational components to operate effectively. Memory functions at two levels: short-term memory maintains conversation context within active sessions, while long-term memory retains insights across multiple sessions over time. Tools provide agents with functional capabilities, accessible either through native integration or via Model Context Protocol (MCP) servers. Identity management enables "more secure authentication and permission management, allowing agents to act on behalf of users or autonomously access resources." Guardrails implement safety controls designed to "detect harmful content, help prevent hallucinations, and make sure responses align with policies and factual accuracy.""
Amazon Bedrock AgentCore Runtime supports the Agent-to-Agent (A2A) protocol to enable communication and interoperability between agents built on different frameworks. A2A standardizes how agents share context, capabilities, and reasoning in a verifiable format and allows workflows to span Strands, OpenAI Agents SDK, LangGraph, Google ADK, and Claude Agents SDK. Bedrock AgentCore Runtime acts as the infrastructure layer that processes inter-agent exchanges. Agentic systems require short-term and long-term memory, tool integrations via native connectors or Model Context Protocol servers, identity management for secure authentication and permissions, and guardrails to ensure safety, factuality, and policy alignment. A2A addresses agent-to-agent coordination while MCP connects agents to tools and resources.
