LangGraph Integration

LangGraph is covered in the same interceptor code as LangChain. The Python adapter patches ToolNode execution methods directly, and the Node SDK’s LangChain integration also knows how to patch LangGraph tool node invocation paths.

The important detail is the execute layer. In the checked-in Python adapter, that is where governance happens for both synchronous and asynchronous dispatch.

from faramesh.adapters.langchain import install_langchain_interceptor

install_langchain_interceptor(include_langgraph=True)

If you are building a LangGraph app, use the same pattern as any other governed runtime: intercept the tool call, evaluate it in Faramesh, and let the graph continue only on allow.
