mcpc vs fast-agent

mcpc: mcpc is a universal CLI for the Model Context Protocol (MCP) that maps MCP operations to intuitive commands for interactive shell use, scripts, and AI coding agents. It supports persistent sessions, code mode with JSON output, and secure authentication. It works with any MCP server over Streamable HTTP or stdio.; 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.
