security-autopilot 0.1.4

MCP server giving Claude Code native security scanning superpowers

🛡️ Security Autopilot

Catches threats in your code. Fixes them automatically. Never asks you to do anything.

The Problem

On March 30, 2026, two malicious versions of axios — one of the most downloaded npm packages on the planet — were quietly published to npm.

They contained zero suspicious code inside axios itself. Any developer who inspected the source would have found nothing wrong.

Instead, they silently injected a fake dependency called plain-crypto-js that ran a postinstall script the moment you ran npm install. That script phoned home to a command-and-control server and dropped a remote access trojan tailored to your OS.

After delivering the payload, it deleted itself and swapped its own package.json for a clean decoy. No trace. No warning. No audit trail.

npm audit reported nothing. GitHub Dependabot reported nothing. Standard code review caught nothing.

This is the new shape of supply chain attacks — and your existing tools aren't built to catch them.

What It Does

Security Autopilot runs silently in the background on your machine from the moment you install it. You never have to open it, ask it anything, or remember it exists.

1. Scans all your existing projects on first install

The moment you install it, Security Autopilot walks through your development folders (~/projects, ~/code, ~/Desktop/projects, etc.), scans every project it finds, and sends you a single desktop notification with a summary. If anything critical is found, it tells you exactly what and where.

2. Watches every project forever after

After the initial scan, it keeps watching. The moment you add or update a package.json, requirements.txt, go.mod, Cargo.toml, or any lockfile — it scans automatically. No commands to run. No Claude Code required.

3. Auto-patches malicious packages

If it detects a known-malicious package (e.g. axios@1.14.1), it doesn't just warn you — it fixes it:

• Finds the highest safe version within the same major (semver-compatible, no breaking changes)
• Runs npm install axios@1.14.0 automatically
• Sends you a desktop notification: "✅ Auto-patched: axios 1.14.1 → 1.14.0"

You never even see the bad version in your project.

4. Fires a loud alert for exposed secrets

If it finds an API key, token, or password committed to your codebase — it sends an immediate desktop notification with step-by-step rotation instructions specific to that credential type:

🚨 SECRET EXPOSED — Action Required AWS KEY exposed in .env. Go to AWS Console → IAM → Users → Security credentials → Delete key immediately.

Full instructions (all steps) are saved to ~/.security-autopilot/secret-alerts.log so you can refer back at any time. Covers AWS, GitHub, Stripe, Slack, SendGrid, Twilio, JWT, and more.

5. Plugs into Claude Code

When Claude Code is open, Security Autopilot exposes four tools Claude can use directly:

Tool	What it does
scan_repo(path)	Full scan — all 4 scanners in parallel, results in plain English
scan_file(filepath)	Scan a single file
get_findings(severity)	Retrieve cached findings from previous scans
watch_project(path)	Start a background watcher on a specific project

You can just say "scan this project" or "show my security findings" and Claude handles the rest.

What It Catches

Threat	How
🔴 Known-malicious packages	Blocklist of confirmed-bad versions updated as attacks happen
🟠 Maintainer account hijacks	Detects publisher email changes between versions
🟠 Postinstall script injection	Flags preinstall, postinstall, prepare lifecycle hooks
🟠 Exposed secrets	API keys, tokens, passwords committed to any file
🟡 CVEs in dependencies	Trivy scans against the full NVD vulnerability database
🟡 Code-level bugs	Semgrep: SQL injection, XSS, eval(userInput), 1000+ patterns
🟡 Recently published versions	72-hour cooldown gate on brand-new releases
🔵 Floating version pins	^ and ~ pins that allow silent upgrades
🔵 Missing SLSA provenance	Packages published without cryptographic build attestations

Install

curl -fsSL https://raw.githubusercontent.com/Omar-Dahleh/security-autopilot/main/install.sh | sh

This single command:

1. Installs uv (Python package manager) if not present
2. Installs security-autopilot from PyPI
3. Installs trivy, gitleaks, and semgrep scanner CLIs
4. Patches ~/.claude/claude.json to register the Claude Code plugin
5. Registers a background daemon that starts automatically at every login
6. Immediately scans all your existing projects

Safe to run twice — fully idempotent.

Telemetry: On first run you'll be asked whether to share anonymous usage data (OS + Python version only). Opt out anytime by deleting ~/.security-autopilot/telemetry_consent.

What Happens After Install

Install completes
      │
      ▼
Daemon starts immediately
      │
      ├─▶ Scans all projects in ~/projects, ~/code, ~/Desktop/projects
      │         └─▶ Desktop notification: "Scanned 8 projects — 2 critical issues found"
      │
      └─▶ Watches forever
                │
                ├─▶ You run npm install axios@1.14.1
                │         └─▶ Detected → auto-patched to 1.14.0 → "✅ Fixed automatically"
                │
                ├─▶ You commit a file with an AWS key
                │         └─▶ "🚨 SECRET EXPOSED — rotate immediately" + full steps
                │
                └─▶ New project appears in ~/projects
                          └─▶ Auto-detected → scanned within 60 seconds

Scanners

Scanner	What it catches	Requires
Supply Chain	Known-bad versions, account hijacks, lifecycle scripts, floating pins	Built-in
Trivy	CVEs in npm, pip, Go, Rust, Java dependencies	Auto-installed
Gitleaks	Hardcoded secrets, API keys, tokens, passwords	Auto-installed
Semgrep	1000+ SAST rules: injection, XSS, insecure patterns	Auto-installed

Security Autopilot works with reduced coverage if a scanner is missing — it never crashes.

For Contributors

uv run pytest tests/ -v        # run all tests
python -m mcp_server.server    # start MCP server manually

See CLAUDE.md for the complete project context, coding rules, and how to add a new scanner.
