agent-protocol vs agent-bridge
agent-protocol: The Agent Protocol provides a single common interface for communicating with AI agents, addressing the challenge of diverse agent interfaces and simplifying comparison. It is a tech-stack agnostic API specification, enabling easier development of devtools and fostering ecosystem growth by reducing boilerplate.; agent-bridge: AgentBridge uses a two-process architecture with a foreground MCP client (bridge.ts) and a persistent background daemon (daemon.ts). It enables bidirectional communication between Claude Code and Codex via a control WebSocket and proxy, with automatic reconnection and message loop prevention.
