This command-line interface application provides interactive chat capabilities with AI models through the Anthropic API, leveraging the Model Context Protocol (MCP) architecture. It empowers users to integrate document content seamlessly into queries, execute predefined commands, and extend functionalities through custom tools. The project serves as a practical example for building robust MCP servers and clients using Python, demonstrating how MCP's core primitives—tools, resources, and prompts—can be combined with Claude AI to create powerful applications with minimal integration code.
