How to create ToolNode using OpenAi Responses built-in tools

[septst]

Hello,

I am trying to use the OpenAi Responses API web_searcher_preview along with my other function tools (@tool) to do some task and Pydantic BaseModels for structured output.

class GetWeather(BaseModel):
    """Get the current weather in a given location"""

    location: str = Field(..., description="The city and state, e.g. San Francisco, CA")



web_searcher_tool = {"type":"web_search_preview"}
tools=[web_searcher_tool, GetWeather]
tool_node = ToolNode(tools)

This gives me error saying "The first argument must be a string or a callable with a name for tool decorator. Got <class 'dict'>. Can anyone please advise how I can use Responses API tools selectively?

Thanks

Same question, how can I use with create_react_agent?

model = ChatOpenAI(model="gpt-4o-mini", temperature=0)

tools = [{"type": "web_search_preview"}]

create_react_agent(
    model,
    tools,
    prompt=prompt,
    name="agent"
)

This is working for me via https://js.langchain.com/docs/integrations/chat/openai/#built-in-tools

However, they have conflicting use of quotes on that page.

Try:

	const agentTools = [
		GetWeather,
		{ type: "web_search" } //no quotes on type
	];

Hope that helps!

Are you able to create a ToolNode using this tool?

[jamielife]

Yes, but if you're using TypeScript (what brought me here), it's not pretty:

	const agentTools = [
		GetWeather,
		{ type: "web_search" } as any //either this
	];
	// or @ts-ignore
	const toolNode = new ToolNode(agentTools);

Just realized you're using Python, so hopefully you don't have to worry about hiding linting errors. Either way, that works for me.

forgot to add this:

    const llm = new ChatOpenAI({ model: "gpt-4o" }).bindTools(agentTools);
