 ## About
 
 The RiLiGar Agents SDK is a robust JavaScript library designed to streamline the development of AI-powered applications through seamless integration with various Large Language Model (LLM) providers such as OpenAI, Google, and Anthropic, as well as Meta's Llama and ModelContext. Built with flexibility and extensibility in mind, it implements the Message Control Protocol (MCP) for reliable agent communication and management.
