FastMCP vs ratel
FastMCP: FastMCP is a Python framework that simplifies the creation of applications adhering to the Model Context Protocol (MCP), enabling AI agents to connect seamlessly with tools and data. It streamlines complex protocol implementation, focusing on delivering the right information to agents at the right time.; ratel: Ratel is a context engineering layer for AI agents that optimizes tool usage by selecting only relevant tools for each task. It aims to reduce token costs and improve accuracy for LLMs by preventing 'tool overload' without relying on vector databases or embeddings.
