Runtime security for AI agents

Catch the call before it
burns the company.

Parry sits between your AI agents and the LLMs they call. It detects prompt injection, tool misuse, and behavioural drift in real time — and blocks the dangerous ones before they fire.

support_agent.py
# before
from openai import OpenAI
client = OpenAI()

# after — that's it
from parry.wrappers.openai import SentinelOpenAI
client = SentinelOpenAI(agent_id="support-bot")

How it works

Three steps. No new infrastructure.

01

Install

pip install parry. Two-line setup. Works with OpenAI, Anthropic, LangChain, CrewAI, AutoGen, LlamaIndex, and Pydantic AI.

02

Wrap your client

Replace your LLM client with the Parry wrapper. Every call is intercepted, classified, and shipped to the detection engine.

03

Watch the dashboard

Live block feed, fleet health, behavioural graphs, session replay. Configure policies and alerts as your agents grow.

What you get

Everything an AI security team needs, on day one.

Built around the way real agents fail: silent drift, opaque tool calls, and prompt injection that only shows up in production.

Catches prompt injection in real time

Pattern, classifier, and LLM-fallback detectors run on every call. HIGH and CRITICAL triggers can block before the LLM is hit.

Watches every tool call

Org-defined allowlists, blocked domains, and budget limits — enforced inline. Detect tool misuse before it touches production data.

Learns each agent's baseline

Per-agent token, latency, and tool-call baselines. Anomaly detection flags drift from real production behaviour, not synthetic benchmarks.

Forensics-grade session replay

Reconstruct any session call-by-call with detection results inline. Full prompt and response for admins, previews for everyone else.

Routes the right alerts to the right place

Slack, email, webhooks, PagerDuty, Opsgenie — gated by severity, auditable, and never noisy.

Compliance reports in one click

Generate SOC 2 / EU AI Act-ready PDFs over any window. Counts and policy posture, never raw prompts — GDPR-safe by design.
