Does my browser run in your cloud?

No, on your PC. The browsers run on your own machine. Over remote access only the agent's calls cross our relay, which keeps no page content, header or address.

Can my agent see my passwords?

Never the value. It works with a placeholder, and Scalebrowser types the real value only on the site it belongs to, over https. Keys a page shows are blacked out before the agent reads them. More on the Secret Layer.

How do I keep it from paying or downloading?

Those stay locked. Payments, file access and automatic downloads are refused unless you change it, and you decide for the camera, location and the rest. Read-only mode hides every tool that changes something.

Why does a page cost so few tokens?

It reads a map, not HTML. Your agent gets the elements it can operate, a reference each, and after an action only what changed. Switch off the tool groups a job does not need, and every request gets smaller too.

Is the MCP in the Free plan?

Yes, remote access too. Free includes the MCP server, remote access from claude.ai, ChatGPT and Grok, and 3 profiles with 1 browser at once. Paid plans run up to 20, and you can try them for 7 days.

Scalebrowser MCP

Hand the browser work to the agent you already use.

It opens pages, signs in, fills forms and solves captchas in a browser profile of its own, reading each page as a compact map. You decide which tools it gets.

Your agent gets the elements it can operate, each with a reference. After every action it reads only the difference, so a long run stays light.
It logs in from the profile's vault, two-factor code included, and the value is typed only on the site it belongs to.
Turnstile, reCAPTCHA, hCaptcha, GeeTest or a press-and-hold button: your agent solves them with its own tools, no solver service to pay.
Create profiles from a template and lease several at once. Each runs the same job in a browser of its own, with its own identity and login.
A PROFILE.md per profile says what the account is for, the tone and what to avoid. It arrives with the lease, together with the profile's open tasks.
Each action lands in your dashboard as a sentence with a screenshot while it happens, and one call turns the run into a video.

Browser questions

Sites ask for a camera, a folder, a payment.

Fewer tools cost fewer tokens: in our tests two models chose as accurately from 33 tools as from 65, at about half the tokens per request.
