# Agent Sentinel

**Enterprise Security Monitoring SDK for AI Agents**

Secure any AI agent in just 3 lines of code with real-time threat detection, behavioral analysis, and comprehensive reporting capabilities.

## Quick Start

```python
from agent_sentinel import monitor, monitor_mcp

# Monitor regular functions
@monitor
def process_data(data: str) -> str:
    return data.upper()

# Monitor MCP tools
@monitor_mcp()
def search_database(query: str) -> str:
    return f"Searching for: {query}"

# Use the functions
result = process_data("hello world")
search_result = search_database("user data")
```

## Unified Reporting

Agent Sentinel now provides **unified reporting** that combines logs, security events, and analysis into a single comprehensive file:

### Programmatic Usage

```python
from agent_sentinel.core.sentinel import AgentSentinel

# Initialize with monitoring
sentinel = AgentSentinel(agent_id="my_agent")

# Your monitored functions run here...

# Generate unified report
report_path = sentinel.generate_unified_report()
print(f"Report generated: {report_path}")

# Get report path
report_path = sentinel.get_unified_report_path()
```

### CLI Usage

```bash
# Generate unified report
agent-sentinel report --config config.yaml --agent-id my_agent

# With custom output
agent-sentinel report --output my_report.json --format json
```

### Report Contents

The unified report includes:

- **📊 Executive Summary**: Status, risk score, security events count
- **🔍 Threat Analysis**: Detailed breakdown of detected threats
- **📈 Performance Metrics**: Monitoring statistics and performance data
- **💡 Recommendations**: Actionable security recommendations
- **📝 Session Logs**: Real-time monitoring logs
- **🛡️ Security Events**: Detailed security event information

### Report Structure

```json
{
  "metadata": {
    "agent_id": "my_agent",
    "generated_at": "2025-07-13T09:12:39.375674+00:00",
    "report_version": "1.0"
  },
  "summary": {
    "status": "CLEAN|WARNING|CRITICAL",
    "total_security_events": 0,
    "risk_score": 0.0,
    "monitoring_duration": 0.0
  },
  "threat_analysis": {
    "total_threats": 0,
    "threat_breakdown": {},
    "severity_distribution": {},
    "risk_score": 0.0
  },
  "recommendations": [
    "No security threats detected. Continue monitoring for best practices."
  ],
  "performance_metrics": {
    "total_events": 0,
    "events_by_type": {},
    "average_confidence": 0.0
  },
  "security_events": [],
  "session_logs": []
}
```

## Installation

```bash
pip install agent-sentinel
```

## What It Does

Agent Sentinel automatically detects and blocks 20+ threat types including:

- **SQL Injection** - Pattern-based detection of malicious SQL queries
- **XSS Attacks** - Cross-site scripting attack prevention  
- **Command Injection** - Shell command injection protection
- **Prompt Injection** - LLM prompt manipulation attempts
- **Data Exfiltration** - Unauthorized data access patterns
- **Behavioral Anomalies** - Unusual agent behavior patterns

## Usage

### Basic Monitoring

```python
from agent_sentinel import monitor, monitor_mcp

# Monitor regular functions and methods
@monitor
def process_user_input(user_data: str) -> str:
    return f"Processed: {user_data}"

# Monitor MCP (Model Context Protocol) tools
@monitor_mcp()
def search_web(query: str) -> dict:
    return {"results": "web search results"}

# Automatic threat detection and reporting
result = process_user_input("safe data")
search_results = search_web("test query")
```

### Advanced Configuration

```python
from agent_sentinel import Sentinel

# Initialize with custom configuration
sentinel = Sentinel(
    agent_id="production_agent",
    environment="production"
)

# Monitor with custom settings
@sentinel.monitor
def critical_operation(data: dict) -> dict:
    return {"status": "success", "data": data}
```

### Session-Based Monitoring

```python
from agent_sentinel import Sentinel

sentinel = Sentinel(agent_id="session_agent")

# Monitor entire user sessions
with sentinel.monitor_session("user_session_123"):
    result1 = process_query(query)
    result2 = generate_response(result1)
    result3 = format_output(result2)
```
