agent-block

Ghost AI agents from your site.

@brainrotcreations/agent-block is a zero-dependency frontend library that blocks AI agents from reading, snapshotting, and automating your website.

npm install @brainrotcreations/agent-block

import { block } from '@brainrotcreations/agent-block';
block();

That's it.

How it works

AI agents (Playwright, Puppeteer, agent-browser, browser-use, Vercel AI SDK) read your site using the browser's accessibility tree — a structured map of every interactive element. agent-block continuously scrambles that tree so agents always get stale, unusable data.

• Detects headless browsers via 20+ fingerprint signals
• Intercepts agent-specific DOM operations before they complete
• Rotates ARIA labels on a timer timed to the LLM response window
• Floods the accessibility tree with decoy elements
• Traps agents in honeypots that trigger on any interaction
