RedTeam ML API MCP

Professional AI/ML API penetration testing and red-team simulation over MCP.

RedTeam ML API MCP is a defensive red-team simulator for ML and LLM APIs.

It exposes MCP tools and a CLI that let a security team run controlled test packs against an authorized AI/ML API endpoint, score the responses, generate evidence, and align results to SOC 2, ISO 27001, and GDPR control areas.

Mindset Shift

This project is designed as an adversarial validation plane for AI systems.

The mindset shift is:

• From prompt lists to measurable security controls.

• From one-time red-team demos to continuous adversarial regression.

• From model safety only to full AI system safety: model, prompt, RAG, tools, identity, UI, and deployment.

• From guardrails as a checkbox to guardrails as evidence-backed controls.

• From pass/fail reports to release decisions with owners, evidence, and remediation.

For AWS-facing work, position it as:

RedTeam ML API MCP validates whether Bedrock Guardrails, application policies, RAG boundaries, and agent tool controls are working before release.

AI API Pentest Mode

The red-team value is the pentest workflow:

1. Define authorized scope and rules of engagement.

2. Perform safe endpoint recon without infrastructure exploitation.

3. Run adversarial AI test campaigns.

4. Capture evidence for each case.

5. Calculate bypass rate by category.

6. Map failures to guardrail and architecture controls.

7. Align results to SOC 2, ISO 27001, and GDPR control areas.

8. Produce JSON and HTML artifacts for security review.

This is designed for authorized AI/ML API penetration testing. It does not perform credential attacks, destructive actions, third-party scanning, or infrastructure exploitation.

Low-Impact Safety

The runner is built to avoid unnecessary pressure on target systems:

• Default delay between test cases.

• Per-request timeout.

• Optional max-case limit.

• Dry-run mode that validates scope without sending prompts.

• Explicit --authorized gate for pentest mode.

Example low-impact run:

redteam-ml-api pentest \
  --target-url http://127.0.0.1:8765/chat \
  --pack aws_2026_professional \
  --authorized \
  --delay-seconds 1.0 \
  --max-cases 5

Core Idea

Many ML APIs are deployed with weak safety, privacy, or operational controls. This project tests those controls before production by simulating realistic but safe adversarial requests.

The simulator focuses on:

• Prompt-injection resilience.

• Sensitive data leakage.

• Unsafe model behavior.

• Excessive confidence or hallucinated policy claims.

• Weak API contract behavior.

• Regression testing between model versions.

MCP Tools

list_attack_packs

Lists available local test packs.

run_red_team

Runs an attack pack against an authorized target.

Input:

{
  "target_url": "http://localhost:8000/chat",
  "pack": "baseline_safe",
  "method": "POST",
  "timeout_seconds": 10
}

evaluate_text

Scores a single response for risk signals.

Input:

{
  "text": "model response here"
}

generate_report

Creates a compact remediation report from a previous run result.

generate_operating_model

Creates a strategic operating-model brief for security teams, red teams, AI architects, platform teams, and executive sponsors.

It maps red-team categories to guardrail controls, architecture controls, owners, and release decisions.

run_ai_api_pentest

Runs an authorized AI/ML API pentest workflow with scope, recon, campaign execution, evidence, metrics, release decision, and saved report artifacts.

Safety Boundary

This project is for authorized defensive testing only. It does not exploit infrastructure, bypass authentication, scan third-party systems, or generate malware. Attack packs are plain JSON so teams can review exactly what is being sent.
