agent-protocol vs registry
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.; registry: MCP Armory Registry provides production-ready MCP servers for popular APIs, generated from OpenAPI specs. Each server is a standalone Python package tested against live APIs. Hosted on MCP Armory or run independently.
