About
T3rnel Browser is an AI browser automation extension and MCP server for Chrome, Edge, Firefox, Opera and Brave. It works in the browser profile you are already signed into — no fresh headless session, no cookie export. DevTools included: copy CSS as styled-components, Emotion, CSS Modules, SCSS, Less, Tailwind or JSX; full-page screenshots that pin sticky headers and dismiss cookie banners; WhatsApp chat capture; flow recording with export to Playwright, Puppeteer, Cypress and Selenium; React component inspection; network and console capture; accessibility, performance and SEO audits; visual diff baselines; form filling, cache clearing and hard reload; infinite-scroll controls; a Markdown/Mermaid/math viewer; and an encrypted credential vault. Then it hands 97 MCP tools to your AI assistant over the Model Context Protocol. Your agent can read a page behind a login, fill a form, or audit an authenticated route — with passwords redacted before they reach the model, page text flagged as untrusted input against prompt injection, an approval gate on high-risk actions, a local audit log, and a time-travel run timeline. Free core tier — no account, no telemetry, everything local. Pro is a one-time $29.99 for three machines, payable by PayPal, card, EcoCash or OneMoney via PayNow.
