What is Model Context Protocol (MCP) Client?

The MCP Ruby client enables seamless integration of external tools with AI services by implementing the Model Context Protocol. It supports various communication transports, including stdio and SSE, and manages multiple MCP servers simultaneously. Users can discover tools, invoke actions, handle notifications, and convert tool formats for AI APIs like OpenAI and Anthropic. The client facilitates real-time streaming results, error handling, and custom RPC methods, making it suitable for complex AI workflows and tool management in Ruby environments.
