Three protocol moves landed together: Devin Desktop adopting the Agent Client Protocol 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 (Apidog). Together they sketch a layered stack: MCP for tools, ACP for the client/IDE, AG-UI for the UI. The strategic move is to design for protocol-portability now so you can mix vendors instead of marrying one. Lock-in gets locked in early.
