Use Trivy vulnerability scanner in offline mode to discover security vulnerabilities in dependency files without internet access.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Trivy Offline Vulnerability Scanning

## Setup

Trivy requires a pre-downloaded vulnerability database for offline scanning.

**Check database exists:**
```bash
ls /root/trivy-cache/db/
# Should show: trivy.db  metadata.json
```

## Key Flags

| Flag | Purpose |
|------|---------|
| `fs <target>` | Scan a file or directory |
| `--format json` | JSON output for parsing |
| `--output <file>` | Save results to file |
| `--scanners vuln` | Only vulnerability scanning |
| `--skip-db-update` | Do not update database (offline) |
| `--offline-scan` | Enable offline mode |
| `--cache-dir <path>` | Path to offline database |
| `--severity HIGH,CRITICAL` | Filter by severity |

## Usage

```python
import subprocess, os, sys

def run_trivy_offline_scan(target_file, output_file, cache_dir='/root/trivy-cache'):
    db_path = os.path.join(cache_dir, "db", "trivy.db")
    if not os.path.exists(db_path):
        print(f"[!] Database not found at {db_path}")
        sys.exit(1)

    command = [
        "trivy", "fs", target_file,
        "--format", "json",
        "--output", output_file,
        "--scanners", "vuln",
        "--skip-db-update",
        "--offline-scan",

How to install

The exact contents, by fingerprint

mdr add cxcscmu/skilllearnbench/trivy-offline-vulnerability-scanning@sha256:c04f07e62d91a527

The line at the top of this page pins the label git:20260424.d50cf5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
