agent-protocol vs Ornn
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.; Ornn: Ornn is an agent-facing skill lifecycle API — the npm registry and CLI fused into one, but for AI agent skills. Agents call Ornn directly over HTTP or MCP to search, pull, install, execute, build, upload, and share skills. It is model-agnostic, working with Claude, GPT, Gemini, or any custom runtime. Designed for agentic-system builders who want to manage reusable skills programmatically rather than hardcoding capabilities into each agent.
