Red Teaming AI Agents: Part 1 - Building a FastAPI LangGraph Agent with NVIDIA NeMo and uv

TLDR

This series establishes security testing for agentic AI systems by mapping vulnerabilities to industry standards:

OWASP Top 10 for LLM Applications (2025) - Industry consensus on LLM risks
MITRE ATLAS™ - Adversarial AI tactics and techniques
Real code examples - FastAPI + LangGraph + NVIDIA NeMo Agent Toolkit

Series Structure:

Part 1 (this article): Build agent testbed, document attack surface
Part 2: Exploit all 5 vulnerabilities with working POC code
Part 3: Implement defense mechanisms (guardrails, sanitization)
Part 4: Advanced defense (context integrity, multi-turn protection)
Part 5: Production deployment with monitoring and incident response

We use uv for package management and NVIDIA NeMo Agent Toolkit (NAT) for production-grade observability.

Why OWASP and MITRE Matter for AI Agent Security

Traditional software security frameworks (OWASP Top 10, CWE/CVSS) were designed for deterministic code. AI agents operate differently:

Autonomous decision-making: Models invoke tools based on natural language interpretation, not explicit code paths
Semantic malleability: Inputs imperceptible to humans can alter behavior
Multi-layer vulnerabilities: Training data, model weights, prompts, and orchestration each present unique attack surfaces

The OWASP Top 10 for LLM Applications (2025) addresses this with application-layer LLM-specific risks. The MITRE ATLAS™ framework provides adversarial tactics and techniques grounded in real-world AI attacks.

Together, they form the ground truth for systematic threat modeling.

Mapping Specialized AI Agent Attacks to Standards

Here’s how we align attack vectors with established frameworks:

Attack Vector	OWASP LLM Top 10	MITRE ATLAS	Core Risk	Part
Prompt Injection	LLM01:2025	AML.T0051.000 (Direct), AML.T0051.001 (Indirect)	Direct control of model behavior via crafted inputs	Part 2
Excessive Agency	LLM06:2025	AML.T0060	Unchecked permissions and autonomous actions	Part 2
Improper Output Handling	LLM05:2025	AML.T0064	XSS, code injection, data exfiltration via unsanitized outputs	Part 2
Data and Model Poisoning	LLM04:2025	AML.T0020, AML.T0018	Compromised training data, search results, or model weights	Part 2
System Prompt Leakage	LLM07:2025	AML.T0051.000 (Meta Prompt Extraction)	Exposure of system architecture, tools, and instructions	Part 2

Key OWASP references:

LLM01:2025 - Prompt Injection (p. 3): “Prompt Injection Vulnerability occurs when user prompts alter the LLM’s behavior or output in unintended ways”
LLM05:2025 - Improper Output Handling (p. 19): “Insufficient validation, sanitization, and handling of outputs generated by LLMs before downstream use”
LLM06:2025 - Excessive Agency (p. 22): “Damaging actions performed in response to unexpected, ambiguous or manipulated LLM outputs”

Part 1: Project Setup with uv and NVIDIA NeMo

Prerequisites

Python 3.11, 3.12, or 3.13
uv (version 0.5.4+) - Install via: pipx install uv
Docker (for local model serving, optional but recommended)

Note: This is created with a MacBook Pro M3 Max. Your mileage may vary with different operating systems and hardware.

Step 1: Create Workflow with NAT

# Create the project scaffolding
nat workflow create ai_agent_red_teaming

cd ai_agent_red_teaming

This generates:

ai_agent_red_teaming/
├── configs -> src/ai_agent_red_teaming/configs  # Symlink (do not edit)
├── data -> src/ai_agent_red_teaming/data        # Symlink (do not edit)
├── pyproject.toml                               # uv managed dependencies
└── src/
    └── ai_agent_red_teaming/
        ├── __init__.py
        ├── configs/
        │   └── config.yml
        ├── register.py
        └── ai_agent_red_teaming.py

Step 2: Add Dependencies with uv

Instead of pip install, we use uv add to update pyproject.toml:

# Create virtual environment and install dependencies within pyproject.toml
uv sync # my pyproject.toml has "nvidia-nat[langchain]~=1.3" b/c that was the option I had when installing nvidia-nat

# Enable the virtual environment
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install core dependencies
uv add "fastapi[standard]" ddgs # will install fastapi, uvicorn, pydantic, and other standard dependencies

The uv sync command:

Resolves all dependencies
Creates a lockfile (uv.lock)
Sets up the virtual environment
Makes everything reproducible across machines

Step 3: Project Structure for Security Testing

Let’s organize the project for systematic red teaming:

mkdir -p src/ai_agent_red_teaming/{agents,tools,security,exploits}

# Create necessary __init__.py files
touch src/ai_agent_red_teaming/{agents,tools,security,exploits}/__init__.py

Final structure:

ai_agent_red_teaming/

│   │   └── web_search_agent.py

Running the Testbed

When to Use `nat serve` (Production)

nat serve --config_file src/ai_agent_red_teaming/configs/config.yml --port 8000

Use this for:

✅ Production deployment
✅ Quick testing of agent logic
✅ Leveraging NAT’s built-in observability

What you get:

Generic /invoke endpoint
Automatic request handling
NAT metrics collection

When to Use `main.py` (Security Testing)

fastapi dev src/ai_agent_red_teaming/main.py --port 8000

Use this for:

✅ Red teaming and attack simulation
✅ Security audit logging
✅ Defense mechanism testing

What you get:

/search - Custom endpoint with security logging
/attack-surface - Documents vulnerabilities
/simulate-attack - (Part 2) Attack simulation framework
/run-defense-test - (Part 3) Defense testing framework

The Key Difference:

nat serve = “Run my agent in production” (generic /invoke endpoint)
main.py = “Test my agent’s security systematically” (custom /search, /attack-surface, /simulate-attack endpoints)

For red teaming, we need main.py’s security testing infrastructure.

Option 1: Using NAT CLI

# Run single query
nat run --config_file src/ai_agent_red_teaming/configs/config.yml \
  --input "What is the current date and search for recent AI news?"

# Evaluate dataset 
nat eval --config_file src/ai_agent_red_teaming/configs/config.yml

# Start API server
nat serve --config_file src/ai_agent_red_teaming/configs/config.yml --port 8000

Option 2: Using FastAPI Directly

# Terminal 1: Start the server
fastapi dev src/ai_agent_red_teaming/main.py --port 8000

# Terminal 2: Test the endpoint
curl -X POST "http://127.0.0.1:8000/search" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "What is the current AI security landscape?",
    "user_id": "researcher_001"
  }'
# or (based off /docs)
curl -X 'POST' \
  'http://127.0.0.1:8000/search' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
    "query": "What is the current AI security landscape?",
    "user_id": "researcher_001"
}'

# Check attack surface
curl http://localhost:8000/attack-surface
# or (based off /docs)
curl http://127.0.0.1:8000/attack-surface

Part 1: Attack Surface Documentation

Here’s what we’ve documented as our testbed’s vulnerabilities:

Layer 1: Input Validation (FastAPI Endpoint)

Vulnerability: Query passed directly to LLM
OWASP: LLM01:2025 - Prompt Injection
MITRE: AML.T0051.000 - Direct Prompt Injection

Request Path:
User Query → FastAPI endpoint → Agent → LLM
    ↓ (No filtering)

Severity: CRITICAL - Direct LLM control
Exploited in: Part 2 - Prompt Injection POC

Layer 2: Agent Decision Making

Vulnerability: Agent invokes tools without constraints
OWASP: LLM06:2025 - Excessive Agency
MITRE: AML.T0060 - Excessive Privileges

Tool Invocation Path:
LLM decides → Agent invokes tool → No permission check
    ↓ (No RBAC or sandboxing)

Severity: CRITICAL - Unintended actions
Exploited in: Part 2 - Excessive Agency POC

Layer 3: Output Validation

Vulnerability: Agent output returned without sanitization
OWASP: LLM05:2025 - Improper Output Handling
MITRE: AML.T0064 - Improper Output Handling

Output Path:
Agent response → FastAPI response → User
    ↓ (No sanitization or encoding)

Severity: HIGH - XSS, injection attacks
Defended in: Part 3

Layer 4: Message History Integrity

Vulnerability: No validation of message history
OWASP: LLM04:2025 - Data and Model Poisoning
MITRE: AML.T0051.001 - Indirect Prompt Injection

Multi-turn Attack:
Turn 1: Innocent query
    ↓ (Results poisoned with hidden instructions)
Turn 2: Follow-up query  
    ↓ (Agent uses poisoned results as context)
Turn 3: Attacker gains control

Severity: CRITICAL - Gradual compromise
Defended in: Part 4

Layer 5: System Prompt Leakage

Vulnerability: System prompt exposure via extraction attacks
OWASP: LLM07:2025 - System Prompt Leakage
MITRE: AML.T0051.000 - Meta Prompt Extraction

Reconnaissance Path:
Attacker query → "What are your instructions?" → Agent reveals system context
    ↓ (No output filtering)

Severity: HIGH - Enables targeted attacks
Defended in: Part 3

Key Takeaways for Part 1

NAT provides automatic observability: Every tool call, token usage, and timing tracked without custom code
uv simplifies dependency management: uv add updates dependencies reproducibly
Attack surface is clear and documentable: Aligns with OWASP/MITRE standards
FastAPI provides the testbed: HTTP interface for systematic attack simulation
5 critical vulnerabilities identified: All demonstrable in Part 2 with working POC code

Conclusion

Part 1 established the foundation for systematic AI agent security testing:

✅ Production-ready testbed: FastAPI + LangGraph + NVIDIA NeMo Agent Toolkit
✅ 5 critical vulnerabilities mapped to OWASP LLM Top 10 and MITRE ATLAS
✅ Attack surface documented with severity ratings and exploit scenarios
✅ Reproducible setup using uv package management

Next in Part 2: We’ll exploit all 5 vulnerabilities with working Python POC code, demonstrating:

Direct and indirect prompt injection attacks
Excessive agency exploitation through tool misuse
Output handling bypasses (XSS, code injection)
Data poisoning via search result manipulation
System prompt extraction techniques
