MemoryLink

CLI tool that prevents secret leaks before they happen.

🔒 100% local. Zero telemetry. Your secrets never leave your machine.

🎯 What is MemoryLink?

MemoryLink scans your code for secrets (API keys, passwords, tokens) and blocks them before commit.

How It Works:

You Code → Git Commit → MemoryLink Scans → ⚠️ Warning (or 🚫 Block)
                                              ↓
                                    🔐 Secrets Quarantined

Result: Code confidently without worrying about leaking secrets!

🛠️ Works With

Use it with any editor, any language, any framework.

👀 What You'll See

When MemoryLink finds a secret:

Modes:

• INACTIVE (default): Warns but allows commits ← Good for learning
• ACTIVE: Blocks commits with secrets ← Good for teams/CI

📦 Installation

Prerequisites

• Node.js 18+ (install)
• npm or pnpm
• Windows users: WSL2 recommended (install guide)

Install from npm

npm install -g memorylink

Verify Installation

ml --version

🚀 Quick Start (30 seconds)

1. Initialize MemoryLink

cd your-project
ml init

What happens:

1. ✅ Scans your entire project for existing secrets
2. ✅ Creates .memorylink/ directory
3. ✅ Installs Git hooks (pre-commit + pre-push)
4. ✅ Updates .gitignore
5. 💡 Shows any detected issues

2. That's It! You're Protected

From now on, every git commit and git push is automatically scanned.

🎯 Core Commands

ml scan - Find Secrets

ml scan                    # Scan entire project
ml scan --path src/        # Scan specific directory

ml mode - Switch Protection Level

ml mode                    # View current mode
ml mode active             # Block on secrets (teams/CI)
ml mode inactive           # Warn only (default)

ml gate - Manual Check

ml gate --rule block-quarantined              # Check project
ml gate --rule block-quarantined --diff       # Check staged files only
ml gate --rule block-quarantined --history    # Check git history

🔒 7-Layer Protection

Layer 1: On-demand scan      → ml scan catches secrets immediately
Layer 2: Pre-commit hook     → Blocks before commit (staged files)
Layer 3: Pre-push hook       → Blocks before push (full scan)
Layer 4: Git history scan    → ml gate --history finds old leaks
Layer 5: Quarantine          → AES-256-GCM encrypted isolation
Layer 6: CI/CD gate          → Auto-enforces when runs in CI
Layer 7: Audit trail         → Tracks everything

📊 Active vs Inactive Mode

Mode Priority

MemoryLink checks these in order (highest to lowest):

1. CLI Flag         --mode active / --enforce / --monitor
2. ENV Variable     ML_MODE=active / ML_MODE=inactive
3. CI Detection     GitHub Actions, GitLab CI, etc. (auto ACTIVE!)
4. Config File      .memorylink/config.json
5. Default          inactive

One-Time Override

ML_MODE=active git push      # Force blocking for this push
ML_MODE=inactive git push    # Allow this push (temporary)
git push --no-verify         # Emergency bypass (Git built-in)

🛠️ CI/CD Setup

GitHub Actions

Add to .github/workflows/memorylink.yml:

name: MemoryLink Gate
on: [pull_request, push]
jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: npm install -g memorylink
      - run: ml gate --rule block-quarantined

Quick Setup Command

ml ci --provider github    # Creates the workflow file for you

🚫 Handling False Positives

Option 1: Inline Comment

const API_ENDPOINT = "https://api.example.com"; // ml:ignore

Option 2: Mark as False Positive

ml gate --mark-false <finding-id>

Option 3: Config File

Add to .memorylink/config.json:

{
  "ignores": {
    "values": ["test_key_not_real"],
    "patterns": ["example-api-key"],
    "files": ["tests/**", "docs/**"]
  }
}
