NVIDIA AI Integration Guide

Status: ✅ Integrated
Date: December 8, 2025
API: NVIDIA free tier (build.nvidia.com)
Model: Meta Llama 2 7B Chat

---

What Changed

The oracle tool now uses NVIDIA's free API to answer compliance questions with actual LLM responses instead of stub answers.

Before

answer = "This is a stub oracle answer. Wire me to your real analyzers..."

After

answer = await tool._call_nvidia_api(prompt)  # Real LLM response

---

Setup (Already Done)

✅ NVIDIA_API_KEY added to .env ✅ mcp/oracle_answer/tool.py integrated with NVIDIA API ✅ CLI updated with --local-only flag for testing ✅ Dependencies documented (httpx for async HTTP)

---

Using NVIDIA Oracle

1. Test with Local-Only Mode (No API Calls)

python3 -m mcp.oracle_answer.cli \
  --question "What are GDPR requirements?" \
  --frameworks GDPR \
  --local-only

Output:

{
  "answer": "Local-only mode: skipping NVIDIA API call",
  "framework_hits": {"GDPR": []},
  "reasoning": "...",
  "model": "nvidia/llama-2-7b-chat"
}

2. Call NVIDIA API (Real LLM Response)

python3 -m mcp.oracle_answer.cli \
  --question "What are our PCI-DSS network segmentation requirements?" \
  --frameworks PCI-DSS \
  --mode strict

Output:

================================================================================
ORACLE ANSWER (Powered by NVIDIA AI)
================================================================================

PCI-DSS requirement 1.2 requires implementation of a firewall configuration 
that includes mechanisms for blocking unauthorized inbound traffic, such as:
- Deny-by-default inbound rules
- Explicit allow rules for business purposes
- Network segmentation to isolate cardholder data environment (CDE)
...

--- Reasoning ---

Analyzed question against frameworks: PCI-DSS. Mode=strict. 
Used NVIDIA LLM for compliance analysis.

--- Framework Hits ---

PCI-DSS:
  • PCI-DSS requirement 1.2 requires implementation of a firewall configuration
  • Explicit allow rules for business purposes
  • Network segmentation to isolate cardholder data environment (CDE)

3. Python API (Async)

import asyncio
from mcp.oracle_answer import OracleAnswerTool

async def main():
    tool = OracleAnswerTool()
    response = await tool.answer(
        question="What are incident response SLA requirements?",
        frameworks=["NIST-CSF", "ISO-27001"],
        mode="strict"
    )
    print(response.answer)
    print(response.framework_hits)

asyncio.run(main())

4. JSON Output (For Integration)

python3 -m mcp.oracle_answer.cli \
  --question "Incident response process?" \
  --frameworks NIST-CSF \
  --json

---

API Configuration

Model: Meta Llama 2 7B Chat

• Free tier: Yes (from build.nvidia.com)
• Limits: Rate-limited, suitable for compliance analysis
• Quality: Good for structured compliance/security questions
• Tokens: ~1024 max per response

Prompt Engineering

The tool constructs context-aware prompts:

prompt = f"""You are a compliance and security expert analyzing infrastructure questions.

Question: {question}

Compliance Frameworks to Consider:
{frameworks}

Analysis Mode: {mode}

Provide a structured answer that:
1. Directly addresses the question
2. References the relevant frameworks
3. Identifies gaps or risks
4. Suggests mitigations where applicable
"""

Response Processing

1. Call NVIDIA API → get raw LLM response
2. Extract framework mentions → populate framework_hits
3. Build ToolResponse → return to caller
4. Log to COMPLIANCE_LEDGER.jsonl → audit trail

---

Error Handling

Missing API Key

OracleAnswerTool()  # Raises ValueError
# "NVIDIA_API_KEY not found. Set it in .env or pass api_key parameter."

Fix:

export NVIDIA_API_KEY="nvapi-..."
# OR already in .env
source .env

API Rate Limit

(API Error: 429 Too Many Requests)
Falling back to local analysis...

Fix: Wait a few minutes, or use --local-only mode for testing.

No httpx Library

ImportError: httpx not installed

Fix:

pip install httpx

---

Integration with MCP Stack

In OpenCode

/agent cloudflare-ops
Query: "Are we compliant with NIS2 incident response timelines?"
[Agent uses oracle_answer tool internally]

In CI/CD (GitOps)

# In .gitlab-ci.yml
oracle_compliance_check:
  script:
    - python3 -m mcp.oracle_answer.cli \
        --question "WAF rules compliant with PCI-DSS?" \
        --frameworks PCI-DSS \
        --json > compliance_report.json
  artifacts:
    reports:
      compliance: compliance_report.json

In Scripts

# In observatory/waf-intel.py (Phase 7)
from mcp.oracle_answer import OracleAnswerTool

async def analyze_waf_rules():
    tool = OracleAnswerTool()
    response = await tool.answer(
        question=f"Are these WAF rules sufficient? {rules}",
        frameworks=["PCI-DSS", "NIST-CSF"],
        mode="strict"
    )
    # Log to COMPLIANCE_LEDGER.jsonl

---

Testing the Integration

Quick Test

# Should work (local-only)
python3 -m mcp.oracle_answer.cli \
  --question "Test?" \
  --local-only

# Expected output: Valid JSON with stub answer

API Test

# Should call NVIDIA API (requires rate limit availability)
python3 -m mcp.oracle_answer.cli \
  --question "What is zero-trust architecture?" \
  --frameworks NIST-CSF

# Expected output: Real LLM response

Unit Test

import asyncio
from mcp.oracle_answer import OracleAnswerTool

async def test():
    # Local-only mode for fast testing
    tool = OracleAnswerTool(use_local_only=True)
    resp = await tool.answer("Test?", frameworks=["NIST-CSF"])
    
    assert resp.answer is not None
    assert resp.framework_hits is not None
    assert "nvidia" in resp.model.lower()
    print("✓ All tests passed")

asyncio.run(test())

---

Compliance Frameworks (Mapped)

The oracle can answer about any framework. Pre-mapped frameworks:

Framework	Example Questions
NIST-CSF	Risk assessment, incident response, access control
ISO-27001	Information security management, controls
GDPR	Data protection, privacy, retention
PCI-DSS	Network security, access control, WAF rules
SOC2	Security controls, audit logs, availability
NIS2	Critical infrastructure, incident reporting
HIPAA	Healthcare data protection, audit controls

---

Cost & Rate Limits

Free Tier (build.nvidia.com):

• Rate limit: ~10-30 requests/hour (varies)
• Cost: $0
• Best for: Development, testing, compliance audits
• Not for: Real-time production at scale

If you hit rate limits:

1. Use --local-only flag (skip API)
2. Cache responses in COMPLIANCE_LEDGER.jsonl
3. Batch questions together
4. Use during off-peak hours

---

Upgrading to Paid API (Future)

When production scales beyond free tier:

1. Upgrade at https://build.nvidia.com/billing
2. Update NVIDIA_API_BASE and NVIDIA_MODEL in tool.py
3. Consider faster models (Mixtral 8x7B, etc.)
4. Implement response caching

# Example: Upgrade to Mixtral
NVIDIA_MODEL = "mistralai/mixtral-8x7b-instruct"

    ↓
build_parser() / OracleAnswerTool.answer()
    ↓
tool._call_nvidia_api(prompt)
    ↓
NVIDIA API (meta/llama-2-7b-chat)
    ↓

Next Steps

Immediate (Now)

• ✅ Test with --local-only
• ✅ Test with real API (if rate limit allows)
• ✅ Verify NVIDIA_API_KEY in .env

Phase 7 (WAF Intelligence)

• Use oracle to analyze WAF rule effectiveness
• Call oracle from waf-intel.py
• Store responses in COMPLIANCE_LEDGER.jsonl

Future (Scale)

• Implement caching for repeated questions
• Upgrade to paid NVIDIA tier if needed
• Add multi-model support (Claude, GPT, etc.)
• Build compliance report generator

---

Troubleshooting

"NVIDIA_API_KEY not found"

# Check .env
grep NVIDIA_API_KEY .env

# If missing, add from https://build.nvidia.com/settings/api-keys
echo "NVIDIA_API_KEY=nvapi-..." >> .env
source .env

API Returns Error 401

(API Error: 401 Unauthorized)

Fix: Check NVIDIA_API_KEY is valid and hasn't expired.

API Returns Error 429

(API Error: 429 Too Many Requests)

Fix: Free tier is rate-limited. Wait 1-5 minutes or use --local-only.

Slow Responses

• Free tier API can be slow (5-15 sec per response)
• Use --local-only for development
• Cache results in COMPLIANCE_LEDGER.jsonl
