fast-agent vs ipybox

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.; ipybox: ipybox is a Python code execution sandbox with first-class support for programmatic MCP tool calling. It generates typed Python tool APIs from MCP server tool schemas, supporting both local stdio and remote HTTP servers. Code executes in a sandboxed IPython kernel with MCP tool call approval for security.
