Pattern: Agent Tooling Is Standardizing on Open Protocols — ACP, AG-UI, and Stateless MCP Forming an Interop Stack
Three protocol moves are landing at once: Devin Desktop adopting the Agent Client Protocol (ACP) so any agent runs inside the IDE, CopilotKit's AG-UI standardizing the agent-to-frontend layer, and MCP going stateless for its July 28 spec. Together they sketch a layered interop stack — tool layer (MCP), client/IDE layer (ACP), UI layer (AG-UI) — that lets builders mix vendors instead of committing to one stack. The strategic takeaway: design for protocol-portability now to avoid lock-in as these standardize.
