| `adv_get_version` | Get server version information | "What version is running?" |
| `adv_mark_false_positive` | Mark findings as false positives | "Mark finding XYZ as false positive" |
| `adv_unmark_false_positive` | Remove false positive marking | "Unmark finding ABC as false positive" |

### MCP Tool Examples

```typescript
// In Claude Code or Cursor, ask the AI assistant:

// Scan current file with full analysis
"Use adv_scan_file to check this file for security issues with LLM validation"

// Scan directory with specific options
"Run adv_scan_folder on the src directory with severity threshold of high"

// Scan code snippet
"Use adv_scan_code to analyze this SQL query for injection vulnerabilities"

// Check scanner status
"Use adv_get_status to see what scan engines are available"
```

### Automatic Result Persistence

All MCP tools automatically save scan results in multiple formats:

- **JSON**: `.adversary.json` - Machine-readable results with full metadata
- **Markdown**: `.adversary.md` - Human-readable report with remediation guidance
- **CSV**: `.adversary.csv` - Spreadsheet-compatible format for analysis

Results are automatically placed alongside scanned files/directories with intelligent conflict resolution.

## Dashboard & Telemetry

### Comprehensive HTML Dashboard

The scanner includes a rich web-based dashboard for comprehensive telemetry analysis:

```bash
# Launch interactive dashboard
adv dashboard
```

**Dashboard Features:**
- **MCP Tool Analytics** - Track tool usage, success rates, and performance
- **Scan Engine Metrics** - Monitor Semgrep, LLM, and validation performance
- **Threat Analysis** - Categorize findings by severity and confidence
- **System Health** - Performance monitoring and statistics
- **Language Analysis** - Track scanning efficiency by programming language
- **Recent Activity** - Timeline view of recent scans and operations

### Telemetry System

Adversary MCP Server includes comprehensive telemetry tracking:

- **Automatic Collection** - All MCP tools, CLI commands, and scan operations are automatically tracked
- **Local Storage** - All data stored locally, never transmitted to external services
- **Zero Configuration** - Telemetry works out-of-the-box with no setup required
- **Performance Insights** - Identify bottlenecks and optimize scanning workflows
- **Usage Analytics** - Understand tool usage patterns and effectiveness

## Architecture

### Implementation

Adversary MCP Server is built using **Clean Architecture** principles with Domain-Driven Design (DDD), ensuring separation of concerns, maintainability, and testability.

### New Architecture Benefits

1. **Separation of Concern**: Business logic isolated from infrastructure
2. **Dependency Inversion**: High-level modules don't depend on low-level details
3. **Testability**: Pure domain logic enables comprehensive unit testing
4. **Maintainability**: Changes to infrastructure don't affect business rules
5. **Scalability**: New scan strategies and validators easily pluggable
6. **Type Safety**: Rich domain models with comprehensive validation

### Architectural Layers

#### **Domain Layer** (Core Business Logic)
- **Entities**: `ScanRequest`, `ScanResult`, `ThreatMatch` - Rich business objects
- **Value Objects**: `ScanContext`, `SeverityLevel`, `ConfidenceScore`, `FilePath` - Immutable domain concepts
- **Domain Services**: `ScanOrchestrator`, `ThreatAggregator`, `ValidationService` - Pure business orchestration
- **Interfaces**: `IScanStrategy`, `IValidationStrategy` - Contracts for external dependencies

#### **Application Layer** (Use Cases & Coordination)
- **MCP Server**: Handles Cursor IDE integration via Model Context Protocol
- **CLI Commands**: Command-line interface for security scanning operations
- **Adapters**: Bridge domain interfaces with infrastructure implementations
  - `SemgrepAdapter` - Adapts Semgrep scanner to domain `IScanStrategy`
  - `LLMAdapter` - Adapts LLM scanner to domain `IScanStrategy`
  - `ValidationAdapter` - Adapts LLM validator to domain `IValidationStrategy`

#### **Infrastructure Layer** (External Services)
- **SemgrepScanner**: Static analysis engine integration
- **LLMScanner**: AI-powered vulnerability detection
- **LLMValidator**: False positive filtering with LLM analysis
- **SQLAlchemy Database**: Persistent storage for telemetry and results
- **File System**: Code file access and Git operations
- **Telemetry System**: Performance tracking and dashboard generation

### Data Flow Architecture

1. **Input Processing**: `ScanRequest` created with `ScanContext` (file/directory/code)
2. **Domain Orchestration**: `ScanOrchestrator` coordinates scanning strategies
3. **Parallel Analysis**: Multiple `IScanStrategy` implementations execute concurrently
4. **Threat Aggregation**: `ThreatAggregator` deduplicates and merges findings
5. **Validation Pipeline**: `ValidationService` filters false positives using AI
6. **Result Assembly**: Rich `ScanResult` with comprehensive metadata
7. **Presentation**: Results formatted for CLI, MCP, or dashboard consumption

### Key Design Patterns

- **Strategy Pattern**: Pluggable scan and validation strategies
- **Adapter Pattern**: Infrastructure integration without domain coupling
- **Factory Pattern**: Bootstrap and dependency injection
- **Value Objects**: Immutable domain concepts with validation
- **Domain Services**: Complex business logic coordination

### How It Works

1. **Multi-Engine Analysis**: Parallel execution of Semgrep static analysis and LLM AI analysis
2. **Intelligent Validation**: LLM-powered false positive reduction with confidence scoring
3. **Threat Aggregation**: Smart deduplication and merging using fingerprint and proximity strategies
4. **Performance Optimization**: Async processing, caching, and batch operations
5. **Comprehensive Telemetry**: SQLAlchemy-backed metrics with interactive Chart.js dashboard
6. **Git Integration**: Diff-aware scanning for efficient CI/CD pipeline integration
7. **Zero-Config Operation**: Auto-discovery and configuration with sensible defaults

## Configuration

### Environment Variables

```bash
# Core settings (optional)
ADVERSARY_LOG_LEVEL=INFO           # Set logging level
ADVERSARY_WORKSPACE_ROOT=/path     # Override workspace detection
```

### Configuration File

Settings are automatically managed through the CLI and stored in `~/.adversary/config.json`:

```bash
# Interactive configuration

# Check current settings
adv status
```
