docs: update ToolboxTool docstring

[jackwotherspoon]

Update port for ToolboxTool to match default port used for Toolbox server of 5000.

ToolboxTool is missing from tools.__init__.py:

adk-python/src/google/adk/tools/__init__.py

Lines 34 to 51 in 9002ace

	__all__= [
	'APIHubToolset',
	'AuthToolArguments',
	'BaseTool',
	'built_in_code_execution',
	'google_search',
	'VertexAiSearchTool',
	'ExampleTool',
	'exit_loop',
	'FunctionTool',
	'get_user_choice',
	'load_artifacts',
	'load_memory',
	'LongRunningFunctionTool',
	'preload_memory',
	'ToolContext',
	'transfer_to_agent',
	]

This means users need to use the full import path for ToolboxTool .

fromgoogle.adk.tools.toolbox_toolimportToolboxTool

This also means ToolboxTool will be excluded from being imported when users import all tools.

fromgoogle.adk.toolsimport*

Adding ToolboxTool to tools.__init__.py makes it easier for customers to leverage MCP Toolbox for databases.

Once this change is released we ca update the ToolboxTool imports in the docs back to their original form.

@pentium10ToolboxTool is for loading tools for MCP Toolbox for Databases. You can find a walkthrough in the ADK docs here.

You start it by installing and running the toolbox server.

Unfortunately, that would add toolbox_langchain as a dependency. But I like the fix for the port!

Ahh great point. I had not noticed toolbox_langchain was not a core dep 🙃
