Cortex vs fast-agent
Cortex: Cortex is an MCP server that gives Claude Code persistent memory inspired by neuroscience. It automatically captures, consolidates, and surfaces relevant context, achieving state-of-the-art retrieval benchmarks across multiple datasets.; 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.
