fast-agent vs retyc-cli

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.; retyc-cli: Retyc CLI is the official command-line interface for Retyc, a European sovereign file-sharing platform with end-to-end post-quantum encryption. It allows you to send transfers and manage datarooms directly from your terminal, and also runs as a local MCP server to let AI agents control Retyc in plain language.
