Agent Protocol: The USB Standard AI Agents Never Got
Agent Protocol tries to solve a real problem: AI agents built with different frameworks can't talk to each other. An [AutoGPT](/tools/autogpt) agent can't hand off work to a [CrewAI](/tools/crewai) agent. A [LangGraph](/tools/langgraph) workflow can't call a custom Python agent through a standard interface. Agent Protocol provides that interface. The question is whether anyone will adopt it before competing standards make it irrelevant.
Agent Protocol delivers on its promises as a ai agent builders tool. While it has some limitations, the benefits outweigh the drawbacks for most users in its target market.
