PolicyAware AI Gateway & Agent Control Plane

PyPI: policyaware | Downloads: Pepy stats | Python: 3.10+ | License: Apache-2.0 | Docs: GitHub Pages

PolicyAware adds deny-by-default policy, PII redaction, MCP tool governance, model routing, runtime evaluation, local code scanning, and audit traces to LLM, RAG, and AI agent applications in minutes.

PolicyAware is an open-source AI control plane and security gateway for governed LLM applications, RAG pipelines, MCP-style tools, and autonomous AI agents. Distributed as a lightweight Python package (pip install policyaware), it helps teams inspect prompts, request context, tool calls, model routing decisions, outputs, local code, and audit traces before AI workflows move into production.

Unlike basic content filters that only check text strings, PolicyAware provides policy-aware governance across requests, tools, models, evaluations, and local code scans.

Deployment model: PolicyAware is an adoption-ready open-source framework that teams embed and operate inside their own AI applications, platforms, and CI workflows. It keeps the base install lightweight with native rules-based governance, and uses optional integrations such as Presidio, ProtectAI/Transformers, NeMo Guardrails, Guardrails AI, Haystack, and provider adapters when teams need deeper detection or ecosystem-specific behavior.

Coding-Agent Integration Packs

PolicyAware includes lightweight workflow packs for coding-agent tools. These packs help agents scan repositories, create policyaware.yaml, add CI scan workflows, explain findings, and recommend the right PolicyAware integration path.

Search-Friendly Use Cases

Enterprise Core Capabilities

1. Agent Control Plane And MCP Governance

• Action-level tool governance: Evaluates connector names, action names, arguments, user role, tenant, region, and approval requirements before agent tools execute.
• Deny-by-default tool shielding: Supports MCP-style tool policies that block unauthorized or destructive actions unless explicitly allowed.

2. Multi-Engine Security And Guardrail Orchestration

• Unified governance pipeline: Combines data protection, YAML policy enforcement, risk classification, model routing, guardrail adapters, evaluation, and audit logging in one modular Python framework.
• Optional security integrations: Supports optional integrations such as Microsoft Presidio for stronger PII detection, ProtectAI/Transformers-based classifiers for ML signals, NVIDIA NeMo Guardrails, and Guardrails AI adapters.

3. Cost-Aware Runtime Routing And FinOps Controls

• Policy-based model routing: Routes requests across local and external model providers based on task type, risk level, region, provider availability, cost, quality, and policy constraints.
• Token and budget controls: Supports token, budget, and risk-aware limits to help reduce runaway agent loops and uncontrolled model usage.

4. Observability, Audit, And Local Code Scanning

• Audit-ready traces: Records structured policy decisions, risk tiers, reason codes, model choices, evaluation scores, token estimates, and request/response snapshots.
• Observability exporters: Provides live sidecar /metrics, Prometheus-style metrics, OpenTelemetry-shaped events, and audit-trace exports for monitoring and compliance workflows.
• Performance and policy debugging: Provides lightweight runtime diagnostics, reproducible local benchmarks, semantic governance metrics, and a visual policy simulator for explaining blocked or mutated agent actions.
• Deterministic policy test harness: Runs seeded concurrent policy stress tests, including 10,000-request CI checks, to catch YAML regressions and thread-safety issues before production.
• Structured rejection handshakes: Returns canonical blocked-action payloads with decision, reason codes, matched rules, trace IDs, remediation, and telemetry fields so API wrappers do not swallow governance context.
• Fail-closed security posture: Treats untrusted policy state, validation failures, checksum mismatches, unavailable remote policy sources, and validator errors as blocked or approval-required conditions instead of implicit allow.
• Dynamic policy retry protection: Applies strict fetch timeouts, refresh TTLs, exponential backoff, jitter, last known-good cache, and emergency fallback policies for central HTTP/S3/GCS/ADLS policy sources.
• Offline AI governance linter: policyaware scan runs locally or in CI before deployment to find PII/PHI/secrets, direct LLM calls, unmapped MCP tools, missing tool governance, weak routing controls, audit gaps, and policy YAML issues. GitHub Actions can block pull requests before unvetted AI tools or prompts reach production.
• Adaptive governance helpers: Generate starter policies from scan findings, use synthetic redaction to preserve prompt utility, return auditable safe-rewrite state patches, preflight multi-step agent plans, and detect shadow-AI patterns such as dynamic installs or runtime tool registration.
• Enterprise structural layers: Use jury consensus for high-risk decisions, sanitize retrieved RAG context before prompt assembly, verify tamper-evident audit chains, and pause runaway agent sessions with token, cost, and tool-rate circuit breakers.
• Edge and policy intelligence: Validate air-gapped local deployment, translate one policy across orchestrators, run drift canaries, and monitor fairness distributions for decisioning agents.
• First-class MCP isolation: Intercept MCP JSON-RPC tools/call requests, evaluate connector/action policy, redact sensitive arguments, and return structured JSON-RPC errors before MCP servers touch the host.
• Framework callbacks: Includes lightweight LangChain and LlamaIndex callback handlers that aggregate streamed tokens and report policy, risk, leakage, eval, and token-accounting results.
• LangGraph node guard: Adds dependency-free node/state and tool-call governance for graph-based AI agents.
• Haystack governance components: Adds optional Haystack-style components for RAG query governance, output evaluation, and agent tool permission checks.
• Microsoft AGT-style evidence export: Converts PolicyAware policy, tool, gateway, and audit decisions into dependency-free evidence JSON for enterprise agent governance workflows.
• Smart integration recommender: Inspects project signals and user hints to recommend FastAPI, LangChain, LangGraph, Haystack, MCP/tool governance, privacy, guardrails, routing, audit, or scan entry points with reasons.
• Policy packs and sidecar mode: Includes compliance-oriented starter policy packs and a lightweight HTTP sidecar so non-Python services can call PolicyAware.
• Policy/code contract checks: Detects drift between tool-governance YAML and Python tool function signatures before production.

Where PolicyAware Fits

Use Guardrails AI or NeMo Guardrails when your main goal is conversational safety, structured outputs, or model response validation.

Use an AI gateway or model router when your main goal is provider abstraction, API key handling, retries, rate limits, fallback, or cost/latency routing.

Use PolicyAware when AI requests and agent actions need governance: user/tenant/context policy, PII/PHI/secrets handling, MCP/tool permissions, approval decisions, model routing after policy approval, evaluations, and audit evidence.

Short version: use PolicyAware when AI actions need governance, not just generation.

PolicyAware is intentionally focused on AI systems. For ordinary web APIs or microservices that do not use LLMs, RAG, MCP tools, or autonomous agents, standard API security controls are usually a better first layer. For deeper ML-based detection or conversational safety, PolicyAware keeps the base install lightweight and lets teams opt into Presidio, ProtectAI/Transformers, NeMo Guardrails, Guardrails AI, Haystack, and provider extras. Runtime overhead should be benchmarked in your own request path, especially when optional ML or external guardrail engines are enabled.

Scan Report Preview

policyaware scan is one of PolicyAware's highest-utility differentiators: it works as an offline AI governance linter for repositories. Most runtime guardrails only discover policy gaps when the application executes. PolicyAware can catch structural AI governance risks during local development or CI/CD.

Installation Profiles

The default install is intentionally lightweight. It includes the core CLI, local scanner, policy engine, routing abstractions, cost/risk governance primitives, audit/eval contracts, and YAML policy support.

pip install policyaware

Install optional integrations only when you need them:

pip install "policyaware[privacy]"     # Presidio + spaCy privacy detection
pip install "policyaware[guardrails]"  # NeMo Guardrails + Guardrails AI
pip install "policyaware[haystack]"    # Haystack RAG/agent integration environment
pip install "policyaware[providers]"   # Provider extras such as Bedrock boto3
pip install "policyaware[ml]"          # Transformers/Torch classifiers
pip install "policyaware[onnx]"        # ONNX runtime path for supported classifiers
pip install "policyaware[all]"         # All optional integrations

For production containers, install only the extras that service needs. The base package stays lightweight; privacy, ML, provider, and guardrail extras add larger third-party dependency stacks.

Backward-compatible aliases are also available:

pip install "policyaware[presidio]"
pip install "policyaware[nemo]"
pip install "policyaware[guardrails-ai]"
pip install "policyaware[full]"

Generate A Starter Policy

Create a NIST-aligned baseline starter policy in the current directory:

policyaware init
policyaware init --profile mcp --out mcp-policy.yaml
policyaware init --profile rag --out rag-policy.yaml
policyaware init --profile pii --out pii-policy.yaml
policyaware init --profile agent --out agent-policy.yaml
policyaware policy validate policyaware.yaml

Use a custom path or overwrite intentionally:

policyaware init --out config/policyaware.yaml
policyaware init --out policyaware.yaml --force

The generated template is deny-by-default and includes baseline rules for PII/PHI/secrets handling, risky MCP/tool command blocking, approval for side-effecting tool actions, token budget caps, and high-iteration agent workflows.

LangChain And LlamaIndex Callbacks

Use callbacks when you already have an LLM framework pipeline and want PolicyAware governance results without changing the model call.

from policyaware.integrations.langchain import PolicyAwareCallbackHandler

policyaware_callback = PolicyAwareCallbackHandler(config="policyaware.yaml")

response = chain.invoke(
    {"question": "Summarize this customer ticket."},
    config={"callbacks": [policyaware_callback]},
)

result = policyaware_callback.last_result
print(result.policy_decision.decision)
print(result.risk.tier)
print(result.output_findings.contains_sensitive)

Streaming-friendly manual example:

from policyaware.integrations.langchain import PolicyAwareCallbackHandler

handler = PolicyAwareCallbackHandler(config="policyaware.yaml")
handler.on_llm_start(prompts=["Email jane@example.com with the ticket summary."])

for token in ["Safe ", "summary ", "without ", "private ", "data."]:
    handler.on_llm_new_token(token)

result = handler.on_llm_end()
print(result.to_dict())

LlamaIndex-style callbacks are also available:

from policyaware.integrations.llamaindex import PolicyAwareCallbackHandler

handler = PolicyAwareCallbackHandler(config="policyaware.yaml")
handler.on_event_start(payload={"query_str": "Answer with citations from policy documents."})
handler.on_llm_new_token("The policy requires citation review [doc-1].")
result = handler.on_event_end(payload={})

Copy-Paste Examples

• Zero-config OpenAI preflight: wrap a raw OpenAI client with local PolicyAware checks before the prompt leaves your app.
• FastAPI LLM policy middleware: protect a FastAPI /chat endpoint with policy checks before model execution.
• LangChain policy guardrails: wrap a chain-style LLM call with deny-by-default policy, PII redaction, and secret blocking.
• MCP tool permission gateway: govern connector-level and action-level tool permissions for agent workflows.
• MCP JSON-RPC policy proxy demo: intercept raw MCP tools/call requests before the server executes filesystem, Git, database, or API actions.
• Haystack RAG governance: add PolicyAware query, output, and tool governance around Haystack-style RAG and agent workflows.
• PII redaction policy: inspect and redact sensitive text before model execution.
• Regulated RAG assistant: require citations and stricter controls for healthcare-style RAG.
• Provider routing by risk: route public-safe requests to low-cost models and high-risk requests to approved models.
• Audit trace viewer: write audit traces and generate a local HTML trace viewer.
• Approval workflow hooks: send high-risk requests to approval instead of calling a model.
• Local code scan: scan local AI app code and generate an HTML governance report.
• Full-stack guardrails: orchestrate NeMo Guardrails, Guardrails AI, or custom validators as input/output guards.

Zero-config raw OpenAI preflight:

import policyaware
from openai import OpenAI

gateway = policyaware.Gateway.from_policy_file("policy.yaml")
client = OpenAI()
user_context = {"user_role": "billing_admin", "session_id": "99x-delta", "risk": "low"}
safe_prompt, token_meta = gateway.inspect_and_mutate(
    prompt="Email jane@example.com about claim ACME-42.",
    context=user_context,
    app="zero-config",
)
print(token_meta["decision"], token_meta["actions"])
response = client.responses.create(model="gpt-4.1-mini", input=safe_prompt)
print(response.output_text)

inspect_and_mutate(...) fails closed with PermissionError for denied or approval-required requests, returns redacted prompt text when policy applies a redact transform, and emits audit/telemetry metadata through the normal PolicyAware runtime path.

Captured terminal output for the runnable examples is available in docs/demo-outputs.md.
