LangChain adapter that enforces PFC governance at the execution boundary
Project description
pfc-langchain
LangChain adapter that enforces PFC governance at the execution boundary.
What it does
pfc-langchain wraps LangChain-style tools and ensures every tool call is evaluated by PFC before execution, blocking unauthorized actions at the moment they would occur.
Install
pip install pfc-langchain
Quickstart
tool should be a callable (or LangChain tool) you want to govern before execution.
from pfc_langchain import GovernedTool
tool = GovernedTool(
tool=transfer_funds,
policy_id="transfer-policy",
pfc_api_key="YOUR_API_KEY",
client=client,
)
How it works
- intercept tool execution
- evaluate via PFC
- allow or block with receipt
