+    Get the display name for an MCP object with proper precedence.
+
+    This is a client-side utility function designed to help MCP clients display
+    human-readable names in their user interfaces. When servers provide a 'title'
+    field, it should be preferred over the programmatic 'name' field for display.
+
+    For tools: title > annotations.title > name
+    For other objects: title > name
+
+    Example:
+        # In a client displaying available tools
+        tools = await session.list_tools()
+        for tool in tools.tools:
+            display_name = get_display_name(tool)
+            print(f"Available tool: {display_name}")
+
+    Args:
+        obj: An MCP object with name and optional title fields
+
+    Returns:
+        The display name to use for UI presentation
