An MCP server plus Firefox and Chrome extensions that let your AI agent act in the browser you already use. Log in once; the agent works on real sites as you, with no throwaway profiles. Runs locally and works with Claude Code, Codex, or any MCP client. Free personal tier on Firefox Add-ons; $39 one-time for commercial use.
Hi Product Hunt. Usable Browser Agent started as the tool I wanted for my own agents: a browser they can actually use.
Most browser automation for agents spins up a clean profile, which means no logins and constant bot checks. This one attaches to your real Firefox or Chrome, so the agent can do the boring logged-in tasks: pull a report from a dashboard, fill a form on a site you use every day, download last month's invoice from a vendor portal.
What is inside: a local MCP server with 53 browser tools, a Mozilla-signed Firefox add-on and a Chrome extension, an installer that registers it with Claude Code and Codex, and safety defaults (hardened mode on, your passwords never reach the agent, CAPTCHAs and 2FA hand off to you).
$39 one-time, no subscription. There is a free personal tier for evaluation. I would love to hear what your agents need from a browser.
