Agent Defense Bench

代理防御台

用于评估基于MCP的AI代理系统中基础设施层防御的全面安全基准。

  

概述

AgentDefense Bench是一个精心策划的安全基准，旨在评估使用模型上下文协议（MCP）对AI代理攻击的防御。它结合了来自13个学术和行业来源的35989个测试用例，涵盖了与LLM驱动的代理相关的17个攻击类别。

Architecture

主要特点：

• 35546个攻击测试用例 跨越17个MCP攻击向量
• 443个良性测试案例 用于假阳性测量
• 多源合成 将学术数据集与现实世界的攻击模式相结合
• MCP原生格式 具有JSON-RPC工具调用结构
• 可重复性 所有数据集都使用SHA-256校验和

攻击类别

该基准涵盖了6个主要威胁领域的17个攻击类别：

安装

需求

• Python 3.9+
• pip或uv包管理器

快速开始

# Clone the repository
git clone https://github.com/arunsanna/AgentDefense-Bench.git
cd AgentDefense-Bench

# Install dependencies
pip install -r requirements.txt

# Verify dataset integrity
sha256sum -c CHECKSUMS.sha256

用法

快速启动评估

# Show help and all options
python scripts/evaluate.py --help

# Test with built-in mock defense (pattern matching)
python scripts/evaluate.py --dataset attacks/combined_attacks.json --defense mock

# Test with your HTTP endpoint
python scripts/evaluate.py --dataset attacks/combined_attacks.json \
    --defense http --endpoint http://localhost:8080/validate

# Test with Open Policy Agent
python scripts/evaluate.py --dataset attacks/combined_attacks.json \
    --defense opa --endpoint http://localhost:8181

# Measure false positive rate
python scripts/evaluate.py --dataset benign_baseline/benign_baseline.json \
    --defense mock --measure-fpr

# Save results to JSON
python scripts/evaluate.py --dataset attacks/combined_attacks.json \
    --defense mock --output results.json --verbose

环境变量

整合你的防御

看 docs/INTEGRATION.md 获取完整的集成指南。

选项1:HTTP端点（推荐）

你的防御必须暴露一个POST端点，该端点接受MCP请求并返回一个被阻止的决定：

# Start your defense server
python examples/http_defense_server.py --port 8080

# Run evaluation
python scripts/evaluate.py --dataset attacks/combined_attacks.json \
    --defense http --endpoint http://localhost:8080/validate

预期端点行为：

POST /validate
Content-Type: application/json
Body: {"jsonrpc": "2.0", "method": "tools/call", "params": {...}}

Response: {"blocked": true, "reason": "path_traversal"}

选项2：开放策略代理

# Start OPA with the example policy
opa run --server --addr :8181 examples/mcp_security.rego

# Run evaluation
python scripts/evaluate.py --dataset attacks/combined_attacks.json \
    --defense opa --endpoint http://localhost:8181

选项3：自定义Python适配器

在中创建自定义适配器 scripts/defense_adapters.py:

from defense_adapters import DefenseAdapter

class MyDefense(DefenseAdapter):
    def evaluate(self, mcp_request: dict) -> bool:
        """Return True to BLOCK, False to ALLOW."""
        # Your detection logic here
        return should_block

程序化使用

import json
from scripts.defense_adapters import get_defense_adapter

# Create adapter for your defense
adapter = get_defense_adapter('http', endpoint='http://localhost:8080/validate')

# Load test cases
with open("consolidated/tier1_critical_tests.json") as f:
    tests = json.load(f).get('attacks', [])

# Evaluate
for test in tests:
    mcp_request = test.get("mcp_request", {})
    blocked = adapter.evaluate(mcp_request)
    expected = test.get("expected_block", True)

    status = "PASS" if blocked == expected else "FAIL"
    print(f"{status}: {test['id']}")
