fast-agent vs rust-docs-mcp

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.; rust-docs-mcp: This MCP server provides agents with tools to explore internal crate structure, access full documentation, trace dependencies, and operate offline. It solves the problem of agents building with unfamiliar crates by offering deep crate intelligence.
