LLM guardrails and AI governance for teams that need a single FastAPI control plane — input validation, prompt packages, retrieval grounding, output checks, policy-as-code, and action risk scoring.

AgentGuard is an open-source FastAPI service that sits between your application and any LLM provider. It enforces LLM guardrails on the way in and out: input safety checks (prompt injection heuristics, jailbreak patterns, PII and secret detection), versioned prompt packages, LLM output validation (schema, citations, grounding heuristics, policy), and agent action governance with risk scoring and optional human approval. All checks are transparent heuristics you can audit and extend in code — not a black-box model. It is built for platform engineers who need auditability and a clear HTTP API, not magic.

Positioning (blunt): AgentGuard is heuristic, transparent guardrails you can read and tune in Python — not a full enterprise safety stack. It does not replace vendor-backed AI safety platforms, certified compliance programs, dedicated red teams, or managed detection for novel attacks. Use it when you want a FastAPI-shaped control plane, clear JSON contracts, and honest limits — not when procurement expects a boxed “AI trust” product with a SOC attached.

Install: PyPI is not live yet — pip install agentguard will 404 until the first upload. Use install from source below. When the package is published, this line will switch to PyPI-first instructions (trusted publishing + .github/workflows/publish-pypi.yml).

AgentGuard is LLM guardrails as a service: the same FastAPI control plane described in the intro — input checks, output validation, prompts, policies, and action risk controls. Teams use it for prompt injection defense (heuristic), PII handling, LLM output validation, and AI governance with a single REST API.

User-facing metric: JSON responses and docs use quality_risk_score (0 = low risk, 1 = high risk). The internal Python package path is still slop_score/; the legacy field score duplicates quality_risk_score for backward compatibility.

Examples of low-quality or risky model output (what the score and checks try to surface):

Who is this for?

• Teams choosing between duct-taped per-service checks, expensive managed “AI safety” suites, and a self-hosted FastAPI control plane — AgentGuard is the third option (middleware & control plane).
• Platform engineers building AI-powered products that need safety and quality guarantees
• AI/ML teams deploying LLM agents that require structured guardrails
• Compliance and risk teams enforcing data protection and policy controls
• Security teams defending against prompt injection, data exfiltration, and PII leakage

The AI Gateway is the single entry point for all LLM and agent requests. Every request passes through authentication, tenant isolation, rate limiting, and model routing before reaching any guardrail or provider.

• AuthN / AuthZ — API key and JWT-based authentication via the X-API-Key header
• Tenant isolation — Per-tenant configuration and policy scoping via X-Tenant-ID
• Rate limiting — Configurable per-tenant RPM limits with in-memory or Redis backends
• Model routing — Abstracted provider layer supporting OpenAI, Anthropic, and custom endpoints
• Correlation tracking — Every request gets a unique correlation_id for end-to-end tracing

Seven parallel safety checks run on every user input before it reaches the LLM:

Each check returns a passed / failed result with metadata. The engine aggregates results into a decision: allow, redact, block, escalate, or safe-complete-only.

Structured, versioned prompt packages replace ad-hoc prompt strings with auditable, lintable configurations.

Six framework types:

Each package includes system instructions, developer policy, refusal policy, grounding instructions, and optional output schemas. The compiler assembles these into LLM-ready message arrays, and the linter flags anti-patterns like missing refusal policies or unbounded context windows.

Retrieval Grounding connects LLM responses to verifiable evidence:

• Query rewriting — Sanitizes and rewrites user queries for safety before searching
• Citation packaging — Wraps retrieved documents with numbered [N] citation markers
• Confidence scoring — Each source gets a confidence score; low-confidence sources are filtered
• Grounding flag — Binary grounded indicator for downstream checks and quality_risk_score

Seven parallel quality checks run on every LLM response:

Results feed into quality_risk_score (composite output quality/risk) and produce an aggregate decision: pass, repair, reject, or escalate.

Controls what autonomous agents can do in production:

• Tool allowlist — Only pre-approved tools can be invoked; unknown tools are denied
• Parameter validation — Tool parameters are checked against expected schemas
• Risk scoring — Each action gets a risk score and level (low, medium, high, critical)
• Human-in-the-loop (HITL) approval — High-risk actions require explicit human approval
• Dry-run mode — Evaluate an action without executing it
• Idempotency keys — Prevent duplicate action execution

Full visibility into every guardrail decision:

• Request tracing — Correlation IDs propagated through every module
• Metrics — Counter-based metrics for all checks, decisions, and evaluation results
• Audit trail — Structured log of every decision with tenant, timestamp, and context
• Evaluation suites — Run golden-dataset regression tests and red-team evaluations against the guardrails pipeline via POST /v1/evals/run

Declarative, tenant-aware policy evaluation:

• Scope levels — Policies can target global, tenant, use_case, role, or channel
• Rule-based decisions — Each rule specifies conditions and a decision (allow, deny, warn, escalate)
• Priority ordering — Rules are evaluated in priority order; first match wins
• Policy-as-code — Policies are YAML files in the policies/ directory, version-controlled alongside your code

A composite metric (quality_risk_score in JSON; internal module name slop score) that summarizes how weak or risky an LLM response looks under heuristic checks. The score ranges from 0.0 (low risk) to 1.0 (high risk). Responses may also include score, equal to quality_risk_score (deprecated label only).

Six weighted components:

Decision thresholds (configurable):

• Python 3.11+
• Docker (optional, for containerized setup)

From source (default until PyPI is published):

git clone https://github.com/MANIGAAA27/agentguard.git && cd agentguard
cp .env.example .env   # optional; set OPENAI_API_KEY for live LLM calls
pip install -e ".[dev]"
PYTHONPATH=src uvicorn agentguard.main:app --reload --host 0.0.0.0 --port 8000

After the first successful PyPI upload, install with pip install agentguard and run uvicorn agentguard.main:app --host 0.0.0.0 --port 8000 (no PYTHONPATH needed).

Open the interactive API docs at http://localhost:8000/docs.

Input and output checks run in parallel; cost is roughly the slowest check. Reproduce timings on your machine with python scripts/bench_guardrails.py. Optional: ENABLE_GUARDRAIL_TIMING_LOGS and EXPOSE_GUARDRAIL_LATENCY_HEADER in .env.example — see Guardrail latency.

git clone https://github.com/MANIGAAA27/agentguard.git && cd agentguard
cp .env.example .env
docker compose up --build -d

Then open http://localhost:8000/docs. This starts the AgentGuard API, Redis, and PostgreSQL.

curl -s -X POST http://localhost:8000/v1/guardrails/evaluate-input \
  -H "Content-Type: application/json" \
  -d '{"text": "What is the refund policy?"}' | python -m json.tool

Expected response:

{
  "correlation_id": "...",
  "decision": "allow",
  "checks": [
    {"check_name": "prompt_injection", "passed": true, "message": "No injection detected"},
    {"check_name": "jailbreak", "passed": true, "message": "No jailbreak detected"},
    {"check_name": "toxicity", "passed": true, "message": "No toxicity detected"},
    {"check_name": "pii_detection", "passed": true, "message": "No PII detected"},
    {"check_name": "secret_detection", "passed": true, "message": "No secrets detected"},
    {"check_name": "restricted_topics", "passed": true, "message": "No restricted topics"},
    {"check_name": "data_exfiltration", "passed": true, "message": "No exfiltration detected"}
  ],
  "redacted_text": null
}

The AI Gateway exposes POST /v1/gateway/complete. With APP_ENV=development, an API key is optional. Set provider credentials in .env (see .env.example).

No API key (local stub provider):

curl -s http://localhost:8000/v1/gateway/complete \
  -H "Content-Type: application/json" \
  -d '{"messages":[{"role":"user","content":"Say hi in one short sentence."}],"model_provider":"local"}' | python -m json.tool

OpenAI (OPENAI_API_KEY in the environment; default provider is OpenAI):

curl -s http://localhost:8000/v1/gateway/complete \
  -H "Content-Type: application/json" \
  -d '{"messages":[{"role":"user","content":"Say hi in one short sentence."}],"model_name":"gpt-4o-mini"}' | python -m json.tool

OpenAI streaming (stream: true → text/event-stream SSE proxy). Run POST /v1/outputs/validate on the reassembled assistant text afterward — see ADR-001.

curl -N http://localhost:8000/v1/gateway/complete \
  -H "Content-Type: application/json" \
  -d '{"messages":[{"role":"user","content":"Say hi."}],"model_name":"gpt-4o-mini","stream":true}'

Python client (httpx):

import httpx

r = httpx.post(
    "http://localhost:8000/v1/gateway/complete",
    json={
        "messages": [{"role": "user", "content": "Say hi in one short sentence."}],
        "model_provider": "local",
    },
    timeout=60.0,
)
r.raise_for_status()
print(r.json())

Minimal embeddable app (same endpoint, no sidecar): examples/minimal_gateway_openai.py.

Start the server (uvicorn or Docker), then in another shell (repo root, .venv with httpx or pip install -e ".[dev]"):

export AGENTGUARD_URL=http://127.0.0.1:8000
python examples/rag_support_kb.py
python examples/agent_with_hitl.py

Mount the gateway and middleware on your own FastAPI() instance:

from fastapi import FastAPI

from agentguard.integrations import include_gateway_router, register_agentguard_middleware

app = FastAPI()
register_agentguard_middleware(app)
include_gateway_router(app)

Optional input dependency (validates a JSON body field named text):

from typing import Annotated

from fastapi import Depends, FastAPI

from agentguard.integrations import guardrailed_user_text, register_agentguard_middleware

app = FastAPI()
register_agentguard_middleware(app)

@app.post("/echo")
async def echo(safe: Annotated[str, Depends(guardrailed_user_text)]):
    return {"you_said": safe}

POST /echo body: {"text": "..."}.

POST /v1/gateway/complete (stable request; response varies by stream):

• Request body: messages (array of {"role","content"}), optional use_case, model_provider, model_name, stream, metadata.
• Response: If stream is false (default): JSON with correlation_id, tenant_id, model, output (provider-shaped, e.g. OpenAI chat.completions). If stream is true and provider is OpenAI: text/event-stream (SSE); validate output separately — ADR-001.

This example chains the modules together — evaluate input, compile a prompt, search for grounding, validate the output, and authorize an action:

import requests

BASE = "http://localhost:8000"
HEADERS = {"X-Tenant-ID": "acme-corp", "Content-Type": "application/json"}

# Step 1: Evaluate input safety
input_result = requests.post(
    f"{BASE}/v1/guardrails/evaluate-input",
    headers=HEADERS,
    json={"text": "How do I reset my password?"},
).json()
assert input_result["decision"] == "allow", f"Input blocked: {input_result['decision']}"

# Step 2: Search for grounding context
retrieval_result = requests.post(
    f"{BASE}/v1/retrieval/search",
    headers=HEADERS,
    json={"query": "How do I reset my password?", "collection": "help_center", "top_k": 3},
).json()

# Step 3: Compile the prompt with retrieved context
compile_result = requests.post(
    f"{BASE}/v1/prompts/compile",
    headers=HEADERS,
    json={
        "package_name": "rag_qa",
        "package_version": "1.0.0",
        "user_message": "How do I reset my password?",
        "retrieved_context": [c["text"] for c in retrieval_result.get("citations", [])],
    },
).json()

# Step 4: (Send compiled messages to your LLM provider and get a response)
llm_output = "To reset your password, go to Settings > Security > Reset Password [1]."

# Step 5: Validate the LLM output
validation_result = requests.post(
    f"{BASE}/v1/outputs/validate",
    headers=HEADERS,
    json={
        "output_text": llm_output,
        "context_text": retrieval_result.get("context_text", ""),
        "require_citations": True,
    },
).json()
print(f"Output decision: {validation_result['decision']}")

# Step 6: Authorize a follow-up action (if the agent needs to act)
action_result = requests.post(
    f"{BASE}/v1/actions/authorize",
    headers=HEADERS,
    json={
        "action": "send_password_reset_email",
        "tool": "email_sender",
        "parameters": {"to": "user@example.com"},
    },
).json()
print(f"Action decision: {action_result['decision']} (risk: {action_result['risk_level']})")

Create tenant-specific policies by adding YAML files to policies/examples/ and referencing them by name in the POST /v1/policies/evaluate request.

Prompt packages are versioned YAML configurations that define how prompts are assembled for each use case. They replace ad-hoc prompt strings with structured, auditable, lintable definitions.

git clone https://github.com/MANIGAAA27/agentguard.git && cd agentguard
pip install -e ".[dev]"

make test

Runs all tests with coverage reporting via pytest (see CI workflow).

make lint      # Check for issues with ruff
make format    # Auto-format with ruff
make typecheck # Static type checking with mypy

make docker-up    # Start app + Redis + PostgreSQL
make docker-down  # Stop all containers

AgentGuard ships as a standard Docker image suitable for any container orchestrator:

1. Build the image: docker build -t agentguard:latest .
2. Configure via environment variables — see the Configuration table above. At minimum, set JWT_SECRET, REDIS_URL, and DATABASE_URL for production.
3. Run behind a reverse proxy (nginx, Traefik, or your cloud load balancer) with TLS termination.
4. Scale horizontally — the API is stateless; rate limiting state lives in Redis.

For detailed architecture diagrams and deployment patterns, see docs/.

AgentGuard’s checks are mostly regex and keyword heuristics. They are useful for defense in depth and fast feedback, but they are not mathematically complete guarantees and are not equivalent to enterprise tools built on dedicated models (e.g. Presidio for PII, LlamaGuard for safety classes, commercial prompt-injection APIs).

The Roadmap includes ML-backed checks. Until those land, treat this repo as transparent heuristics you can audit, not a drop-in replacement for a full enterprise safety stack. Behavior details live in module docstrings under src/agentguard/**/checks/.

• Documentation site — GitHub Pages via .github/workflows/docs.yml (pushes to gh-pages). One-time setup: Settings → Pages → source Deploy from a branch → gh-pages / / (root). If the workflow cannot push, set Settings → Actions → General → Workflow permissions → Read and write.
• PyPI package — First upload pending; README will advertise pip install agentguard only after it resolves on PyPI (trusted publishing, tag + Release → publish-pypi)
• ML-backed checks — Optional classifiers / adapters (e.g. toxicity, injection) alongside transparent heuristics
• Dashboard UI — Web-based admin console for policy management, audit trail browsing, and real-time metrics visualization
• SDK clients — Official Python, TypeScript, and Go client libraries with typed interfaces
• Webhook integrations — Push guardrail decisions and alerts to Slack, PagerDuty, and custom endpoints
