## Example Workflows

### Analyze Your Detection Coverage

```
You: "I have these technique IDs from my detection rules: T1059.001, T1059.003, T1547.001, T1053.005. 
      What's my coverage like?"

LLM uses: analyze_coverage(covered_ids=["T1059.001", "T1059.003", "T1547.001", "T1053.005"])

Returns:
{
  "total_techniques": 625,
  "covered_techniques": 4,
  "coverage_percentage": 0.6,
  "by_tactic": {
    "execution": { "total": 45, "covered": 2, "percentage": 4 },
    "persistence": { "total": 52, "covered": 2, "percentage": 4 },
    ...
  },
  "gaps": ["T1059.002", "T1059.004", ...]
}
```

### Generate a Coverage Navigator Layer

```
You: "Generate a Navigator layer showing my coverage"

LLM uses: generate_coverage_layer(
  covered_ids=["T1059.001", "T1059.003", "T1547.001"],
  name="My Detection Coverage"
)

Returns: Navigator layer JSON (paste into https://mitre-attack.github.io/attack-navigator/)
```

### Compare Against a Threat Group

```
You: "What APT29 techniques am I missing?"

LLM uses: 
1. get_group_techniques(group_id="G0016")  
2. find_group_gaps(group_id="G0016", covered_ids=[your techniques])

Returns: List of technique IDs APT29 uses that you don't have coverage for
```

### Generate Gap Analysis Layer

```
You: "Show me a visual of my gaps against APT29"

LLM uses: generate_gap_layer(
  covered_ids=[your techniques],
  target_ids=[APT29 techniques],
  name="APT29 Gap Analysis"
)

Returns: Navigator layer showing green=covered, red=gaps
```

## 🔗 Using with Security Detections MCP

**This MCP pairs perfectly with [security-detections-mcp](https://github.com/MHaggis/Security-Detections-MCP)** to create a complete threat detection workflow:

| MCP | Purpose |
|-----|---------|
| **security-detections-mcp** | Query 6,500+ detection rules (Sigma, Splunk ESCU, Elastic) |
| **mitre-attack-mcp** | Analyze coverage against ATT&CK framework |

### Combined Workflow Example

```
You: "What's my MITRE coverage based on my Splunk detections?"

LLM workflow:
1. Query detections-mcp → get_stats() to see total detections with MITRE mappings
2. Query detections-mcp → list_by_mitre_tactic("execution") to get technique coverage
3. Query mitre-attack-mcp → analyze_coverage(covered_ids) to analyze gaps
4. Query mitre-attack-mcp → generate_coverage_layer() to visualize

Result: Full coverage analysis with visual Navigator layer
```

### Install Both Together

Add both to your `~/.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "security-detections": {
      "command": "npx",
      "args": ["-y", "security-detections-mcp"],
      "env": {
        "SIGMA_PATHS": "/path/to/sigma/rules",
        "SPLUNK_PATHS": "/path/to/security_content/detections",
        "ELASTIC_PATHS": "/path/to/detection-rules/rules"
      }
    },
    "mitre-attack": {
      "command": "npx",
      "args": ["-y", "mitre-attack-mcp"],
      "env": {
        "ATTACK_DOMAIN": "enterprise-attack"
      }
    }
  }
}
```

## Navigator Layer Output

The layer JSON is compatible with [ATT&CK Navigator](https://mitre-attack.github.io/attack-navigator/):

```json
{
  "name": "My Detection Coverage",
  "versions": { "attack": "18", "navigator": "5.1.0", "layer": "4.5" },
  "domain": "enterprise-attack",
  "techniques": [
    { "techniqueID": "T1059.001", "score": 100, "color": "#31a354", "comment": "Covered" },
    { "techniqueID": "T1059.003", "score": 0, "color": "#ff6666", "comment": "Gap" }
  ],
  "gradient": { "colors": ["#ff6666", "#fdae6b", "#31a354"], "minValue": 0, "maxValue": 100 }
}
```

To visualize:
1. Go to https://mitre-attack.github.io/attack-navigator/
2. Click "Open Existing Layer" → "Upload from local"
3. Paste the JSON

## Database

The ATT&CK index is stored at `~/.cache/mitre-attack-mcp/attack.sqlite`.

- Auto-downloads STIX data from MITRE on first run
- Caches for 7 days
- Use `rebuild_index()` to force refresh

## Stats (Enterprise ATT&CK v18)

| Type | Count |
|------|-------|
| Techniques | ~200 |
| Sub-techniques | ~450 |
| Tactics | 14 |
| Groups | ~140 |
| Software | ~700 |
| Mitigations | ~280 |
| Data Sources | ~40 |

## Development

```bash
npm install
npm run build
