com.google.adk.workflow.ToolNodes

@Experimental
public final class ToolNodes
extends Object

Static factories for workflow nodes that run a BaseTool, such as an MCP tool or an agent wrapped as a tool. A node calls its tool between the plugins' tool callbacks and keeps only the tool's state and artifact changes; a tool declared to return nothing gives no output. A tool that asks for confirmation does not pause the workflow: the node outputs the tool's placeholder error.

Method Summary

Modifier and Type	Method	Description
static Node	asNode(BaseTool tool)	Returns a node named after tool, with the default NodeConfig.
static Node	asNode(BaseTool tool, String name)	Returns a node named name that runs tool, with the default NodeConfig.
static Node	asNode(BaseTool tool, String name, NodeConfig config)	Returns a node named name that runs tool with config; session state supplies any required parameter that the input lacks.

Method Details

asNode

public static Node asNode(BaseTool tool)

Returns a node named after tool, with the default NodeConfig. Otherwise it behaves as asNode(BaseTool, String, NodeConfig) describes.

asNode

public static Node asNode(BaseTool tool,
 String name)

Returns a node named name that runs tool, with the default NodeConfig. Otherwise it behaves as asNode(BaseTool, String, NodeConfig) describes.

asNode

public static Node asNode(BaseTool tool,
 String name,
 NodeConfig config)

Returns a node named name that runs tool with config; session state supplies any required parameter that the input lacks. The input may be a map of arguments; an object the JSON mapper writes as a JSON object, such as a record; a JSON object as text or as a Content; or null or blank text for none. A tool with one parameter, or one required parameter, takes any other input as that parameter; other tools fail.
