agent-protocol vs fast-agent
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.; fast-agent: fast-agent is a CLI-first framework for building and interacting with sophisticated multimodal AI agents and workflows. It offers comprehensive support for various LLM providers, structured outputs, and vision, with unique features like MCP Feature support and live streaming responses to the terminal.
