Can we still use JSON Toolkit in LangGraph?

[sherryxiao1988]

Here is the documentation for JSON Toolkit:
https://python.langchain.com/docs/integrations/tools/json/

It seems after migrating to LangGraph, we should convert the toolkit to something interacts with the state graph as well? Can we just use the toolkit as it is in a supervision multi-agent architecture?

Thanks.

Have you tried using a pre-built agent with the json tools?

from langgraph.prebuilt import create_react_agent
...
son_spec = JsonSpec(dict_=data, max_value_length=4000)
json_toolkit = JsonToolkit(spec=json_spec)
...
graph = create_react_agent(model, tools=json_toolkit.get_tools())

Thanks @eyurtsev! I realized what you shared should just work, I'll just need to create a Node that takes a state and then can integrate this agent with the graph.
