[!WARNING] ### LEGAL DISCLAIMER & AUTHORIZED USE POLICY RedAgent is strictly designed for authorized security auditing, internal red teaming, academic research, and defensive hardening. Testing AI agents, API endpoints, or systems without prior explicit, written authorization from the system owner is illegal and violates computer crime laws (e.g., Computer Fraud and Abuse Act - CFAA, EU NIS2, UK Computer Misuse Act). The authors and contributors of RedAgent assume no liability and are not responsible for any misuse, damage, or legal consequences resulting from this tool. By using RedAgent, you agree to comply with all applicable local and international cybersecurity laws.

Why RedAgent?

Traditional Dynamic Application Security Testing (DAST) and API scanners are fundamentally incapable of discovering non-deterministic LLM vulnerabilities: - They do not understand conversational state, prompt boundaries, or instruction delimiters. - They conclude execution after a single HTTP 200 or standard polite refusal ("I am sorry, but..."). - They cannot evaluate autonomous function calling (Excessive Agency) or vector memory leakage (RAG Data Exfiltration).

RedAgent solves this by deploying a team of adversarial AI agents. Powered by a Dynamic Test Iteration Engine with Backtracking, our specialist agents analyze target refusals, systematically mutate boundary conditions (delimiters, role claims, parameter tampering), and continue exploring alternative attack vectors until every path on the exploration tree is exhausted.

Key Features

• OWASP LLM Top 10 Coverage: Automated test generation mapped to Prompt Injection (LLM01), Sensitive Information Disclosure (LLM06), and Excessive Agency / Insecure Tool Abuse (LLM07/LLM08).
• Persistent Refinement with Backtracking: Agents do not surrender on a single defense.

When a prompt is blocked by a guardrail, the engine backtracks and mutates formatting, delimiters, and semantic framing. - ChromaDB Vector Knowledge Store: Persistently indexes adversarial seeds, boundary test templates, and OWASP evaluation rubrics (with zero-dependency in-memory fallback). - Pluggable Target Connectors: Test local mock agents, staging bots, or live enterprise agents over REST API endpoints (RestTargetConnector). - Actionable Remediation Roadmap: Automatically generates concrete developer fixes, including regex guardrail patterns, system prompt hardening snippets, and RBAC constraints. - Dual Mode (CLI + SDK): Run as a standalone terminal security scanner or embed into Python CI/CD pipelines.

System Architecture

RedAgent operates as a stateful Directed Acyclic Graph (DAG) built on LangGraph, Pydantic v2, and LiteLLM:

Specialized Multi-Agent Roles

Quickstart & Installation

1. Installation

Clone the repository and install in editable mode:

git clone https://github.com/Zwony/RedAgent.git
cd RedAgent

# Create and activate virtual environment
python -m venv venv
# Windows:
.\venv\Scripts\activate
# Linux/macOS:
source venv/bin/activate

# Install dependencies and CLI tool
pip install -e .

2. Configure Environment (Optional)

To use cloud LLMs (OpenAI, Anthropic, Gemini) for the attack and evaluation agents, copy .env.example:

cp .env.example .env

And specify your API keys:

OPENAI_API_KEY=your_key_here
DEFAULT_ATTACKER_MODEL=gpt-4o

CLI Usage

1. Scaffold a New Target Agent Profile

Generate a starter configuration file with customizable tools and RAG settings:

redagent init --output target.json --name "CustomerServiceAgent"

2. Run Security Audit on an AI Agent Profile

Execute the stateful multi-agent DAG against your target and export an executive Markdown report:

redagent scan --target target.json --output audit_report.md

Or export as structured JSON:

redagent scan --target target.json --output report.json

3. Run the Interactive Sandbox Demo

Experience the multi-agent refinement loop against a simulated banking assistant:

Sample Audit Output

When an audit finishes, RedAgent renders a comprehensive executive summary and remediation table:

Security Audit Posture Summary
+-----------------------------------------------+
| Metric | Value |
|-------------------+---------------------------|
| Target Name | Acme Customer Service Bot |
| Overall Rating | CRITICAL_RISK |
| Max Risk Score | 9.1 / 10.0 |
| Total Test Cases | 6 |
| Findings Detected | 3 |
+-----------------------------------------------+

Vulnerability Findings & Evaluator Analysis

| | Injection | | | delimiters |
| fnd_df05d8d0 | LLM08: | CRITICAL | confirmed_vuln | Enforce RBAC |

+-----------------------------------------------------------------------------+

=> Hardening & Guardrail Remediation Roadmap:
#1 [LLM08: Excessive Agency]: Enforce server-side RBAC and schema constraints on tool 'lookup_customer_order'.
#2 [LLM08: Excessive Agency]: Require explicit user confirmation token for sensitive function calls ('cancel_and_refund_order').
#3 [LLM01: Prompt Injection]: Sanitize input delimiters such as triple backticks or custom markup tags.

Python SDK & CI/CD Integration

Embed automated AI red teaming directly into test suites or CI/CD pipelines:

import asyncio
from redagent import RedTeamGraphEngine, TargetInfo, TargetToolDefinition

async def test_ai_agent_security():
# 1. Define Target System
target = TargetInfo(
target_id="support_bot_staging",
name="Customer Service Assistant",
endpoint_type="rest_api",
endpoint_url="https://staging.acme.internal/agent",
accessible_tools=[
TargetToolDefinition(
name="query_orders",
description="Queries customer orders by ID",
is_sensitive=True,
)
],
has_rag=True,
rag_sources=["internal_kb"],
)

# 2. Run RedAgent Engine
engine = RedTeamGraphEngine()
final_state = await engine.run(target=target)

# 3. Assert Security Baseline in CI/CD
report = final_state.audit_report
assert report.overall_rating.value in ("SECURE", "LOW_RISK"), (
f"Security audit failed with posture: {report.overall_rating.value} (Risk: {report.overall_risk_score}/10)"
)

if __name__ == "__main__":
asyncio.run(test_ai_agent_security())
