class RealMCPClient(BaseProtocol):
    """Real MCP Client with background server management.

    This client starts and manages actual MCP servers as background processes.
    Use this for production scenarios with real MCP servers like:
    - @modelcontextprotocol/server-github
    - @modelcontextprotocol/server-filesystem
    - Custom MCP servers

            server_command: Command to start MCP server
            mcp_server: BackgroundMCPServer instance
            available_tools: Dictionary of discovered tools

    Example:
            ```python
            from superoptix.protocols.mcp.client import RealMCPClient

            # GitHub MCP server
            client = RealMCPClient(
