Permit

Permit.io offers fine-grained access control and policy enforcement. With LangChain, you can integrate Permit checks to ensure only authorized users can access or retrieve data in your LLM applications.

Installation and Setup

pip install langchain-permit
pip install permit

Set environment variables for your Permit PDP and credentials:

export PERMIT_API_KEY="your_permit_api_key"
export PERMIT_PDP_URL="http://localhost:7766"   # or your real PDP endpoint

Make sure your PDP is running and configured. See Permit Docs for policy setup.
