Copy-Paste Examples

These examples are small runnable folders designed for developers searching for practical PolicyAware integration patterns. Each example includes a README.md, runnable Python, YAML policy, and captured terminal output.

Core Examples

Example	What It Shows	Link
FastAPI LLM Policy Middleware	Protect a FastAPI /chat endpoint with policy checks before model execution.	https://github.com/ktirupati/policyaware/tree/main/examples/fastapi-llm-policy-middleware
LangChain Policy Guardrails	Wrap a chain-style LLM call with deny-by-default policy, PII redaction, and secret blocking.	https://github.com/ktirupati/policyaware/tree/main/examples/langchain-policy-guardrails
MCP Tool Permission Gateway	Govern connector-level and action-level tool permissions for agent workflows.	https://github.com/ktirupati/policyaware/tree/main/examples/mcp-tool-permission-gateway

Governance Examples

Example	What It Shows	Link
PII Redaction Policy	Inspect and redact sensitive text before model execution.	https://github.com/ktirupati/policyaware/tree/main/examples/pii-redaction-policy
Regulated RAG Assistant	Require citations and stricter controls for healthcare-style RAG.	https://github.com/ktirupati/policyaware/tree/main/examples/regulated-rag-assistant
Provider Routing By Risk	Route public-safe requests to low-cost models and high-risk requests to approved models.	https://github.com/ktirupati/policyaware/tree/main/examples/provider-routing-by-risk
Audit Trace Viewer	Write audit traces and generate a local HTML trace viewer.	https://github.com/ktirupati/policyaware/tree/main/examples/audit-trace-viewer
Approval Workflow Hooks	Send high-risk requests to approval instead of calling a model.	https://github.com/ktirupati/policyaware/tree/main/examples/approval-workflow-hooks

Recommended First Run

pip install policyaware
cd examples/pii-redaction-policy
python demo.py

Expected output:

contains_pii=True
categories=email, phone
redacted=Contact [REDACTED_EMAIL] or [REDACTED_PHONE] about claim ACME-42.
gateway_decision=conditional_allow
gateway_actions=redact
