T3rnel is a browser extension that provides DevTools-style inspection tools—CSS inspection, full-page screenshots, Markdown viewing, page audits, and record/replay—while also acting as an MCP server so AI coding agents like Claude Code, Cursor, and others can drive the browser the user is already signed into. It is aimed at developers who want to let an AI agent control their real browser session safely, with human oversight and credential protection.
Nothing measured yet. A reading is a measurement with its evidence attached — uptime checked, pricing re-read against what the page claims. Raise a checkable claim in a field note below and Atlas will measure it.
