agent-probe

Agent-level adversarial resilience testing for AI agents.

Tests what others don't: tool interactions, memory poisoning, permission escalation, data exfiltration via tool calls, system prompt leakage.

Why

Every existing red-teaming tool (PyRIT, DeepTeam, b3, promptfoo) tests the LLM backbone. None of them test the agent layer — the tools, the memory, the permissions, the multi-step workflows where real attacks happen.

agent-probe fills that gap.

Install

pip install agent-probe-ai

Quick Start

# Run all probes against an HTTP agent endpoint
agent-probe probe http://localhost:8000/chat

# Run specific categories
agent-probe probe http://localhost:8000/chat --categories prompt_leakage memory_poisoning

# JSON output for CI/CD
agent-probe probe http://localhost:8000/chat --json

# Fail if score below threshold (for CI gates)
agent-probe probe http://localhost:8000/chat --threshold 70

# List available probe categories
agent-probe list

Probe Categories

24 probes across 8 categories. Zero external dependencies.

How It Works

agent-probe sends adversarial messages to your agent's HTTP endpoint and analyzes responses for compliance signals, data leakage, and unsafe tool calls. Each probe simulates a specific attack vector that targets the agent layer, not the underlying LLM.

Your Agent <── adversarial messages ── agent-probe
    │                                      │
    └── responses ──────────────────────>  analyze for:
                                           - leaked secrets
                                           - unsafe tool calls
                                           - compliance signals
                                           - prompt disclosure

CI/CD Integration

# GitHub Actions
- name: Agent security scan
  run: |
    pip install agent-probe-ai
    agent-probe probe ${{ secrets.AGENT_URL }} --threshold 70 --json

Agent Endpoint Protocol

agent-probe sends POST requests with this JSON format:

{
  "message": "the probe message",
  "context": [
    {"role": "system", "content": "..."},
    {"role": "user", "content": "..."},
    {"role": "assistant", "content": "..."}
  ]
}

Expected response:

{
  "response": "agent's text response",
  "tool_calls": [{"name": "tool_name", "arguments": {...}}]
}
