✓ AI agent can parse, prioritize, and auto-fix
Install the CLI and run audits from Claude Code, Cursor, or any AI agent.
1. Install the CLI
npm install -g @etalon/cli2. Run in your project
etalon audit ./...and watch it work.
MCP server skill for automatic discovery and use
Model Context Protocol (MCP) lets AI agents use external tools directly. ETALON's MCP server enables Claude Desktop, Cline, and other agents to run audits, generate policies, and fix violations automatically — no manual commands needed.

Every command works in terminal or via AI agent API
Scan your codebase for privacy violations. Detects tracker SDKs, PII in schemas, insecure cookies, and security config issues.
Launch headless browser and intercept all network requests to identify third-party trackers.
Test if trackers fire before consent and after rejecting cookies. Catch GDPR violations.
Cross-reference your privacy policy against actual trackers detected. Find undisclosed vendors.
Create a complete 8-section GDPR privacy policy from your actual code and trackers.
Map how PII flows through your app: sources → storage → sinks.
Add ETALON to your project: config, CI/CD, and pre-commit hooks.
Look up any domain in ETALON's vendor database. Get full metadata.
Generate SVG compliance badge for your README. Show your privacy grade.
Show ETALON vendor registry metadata.
All commands work locally. No cloud dependencies.
Your code never leaves your machine.
Start free with the CLI. Upgrade for hosted scanning, monitoring, and team features.
ETALON identifies 175+ known tracking vendors across 475+ domains, including Google Analytics, Facebook Pixel, Hotjar, TikTok, LinkedIn, and more. It scans both your codebase (tracker SDKs, PII, insecure cookies) and live website (network requests, consent flows). Unknown third-party domains are also flagged.
ETALON is open-source, free, and does far more: code auditing, policy generation, consent testing, data flow mapping, and policy-vs-reality checking. Traditional tools only scan deployed websites and cost $5K+/year. ETALON catches issues before deployment and generates your privacy policy automatically.
Yes. The generate-policy command analyzes your codebase, detects third-party services, maps data flows, and produces a complete 8-section GDPR-compliant privacy policy. Output in Markdown, HTML, or plain text. It replaces $10K+ in legal consulting fees.
The CLI runs entirely on your machine — no data is sent anywhere. All 10 commands work locally with zero cloud dependencies. Your code never leaves your machine.
Run `etalon init ./ --ci github` to auto-generate GitHub Actions workflows with fail conditions. Also supports GitLab CI and pre-commit hooks. Break the build on critical violations.
