fast-agent vs agent-tool
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.; agent-tool: agent-tool is a single-binary MCP tool server that provides over 50 tools for AI coding agents. It addresses common issues like tab indentation corruption, encoding breakage, and lack of reverse engineering support. With smart indentation and encoding preservation, it seamlessly replaces built-in tools.
