fast-agent vs neurostack

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.; neurostack: NeuroStack is a self-hosted MCP server and CLI that indexes Markdown vaults by meaning, providing AI agents with persistent memory across sessions. It detects stale notes, supports semantic and keyword search, and uses tiered retrieval to minimize token usage. Fully local, it never modifies your files.
