# nemo_relay.integrations.langgraph.tool_node

> Managed NeMo Relay wrappers for standalone LangGraph `ToolNode` objects.

Generated from `python/nemo_relay/integrations/langgraph/tool_node.py`.

Module `nemo_relay.integrations.langgraph.tool_node`.

Managed NeMo Relay wrappers for standalone LangGraph `ToolNode` objects.

## Functions

### `wrap_tool_call`

```python
def wrap_tool_call(request: ToolCallRequest, execute: Callable[[ToolCallRequest], ToolMessage | Command[Any]]) -> ToolMessage | Command[Any]
```

Run one synchronous LangGraph tool call through NeMo Relay.

### `awrap_tool_call`

```python
async def awrap_tool_call(request: ToolCallRequest, execute: Callable[[ToolCallRequest], Awaitable[ToolMessage | Command[Any]]]) -> ToolMessage | Command[Any]
```

Run one asynchronous LangGraph tool call through NeMo Relay.

### `create_tool_node`

```python
def create_tool_node(tools: Sequence[BaseTool | Callable[..., Any]], **tool_node_kwargs: Any) -> ToolNode
```

Create a LangGraph `ToolNode` whose tool calls use managed Relay execution.
