Handlus

Get the Handlus extension

No account needed to download. Install it in each Chrome profile you want your agent to use, then connect each one.

Chrome Web StoreRecommended

It updates itself. Open this page in each Chrome profile and click Add to Chrome.

Zip file

New versions arrive here first. Use it when you cannot use the Web Store, or to get the newest version right away. One zip works for every Chrome.

Install from the Chrome Web Store

  1. Click Add to Chrome, then Add extension in the box that opens

    chromewebstore.google.com
    The Handlus page on the Chrome Web Store, with the Add to Chrome button to the right of the title

    When it finishes, the welcome page opens by itself. Chrome keeps it up to date for you.

Install from the zip file

  1. Double-click the downloaded zip to unzip it

    The Downloads folder in Finder on a MacBook screen. Double-clicking the handlus-extension zip puts a handlus-extension folder next to it

    ① Double-click the zip and ② a handlus-extension folder appears. Move this folder somewhere you won't delete it, such as your Documents folder. Chrome keeps loading the extension from it. On Windows, right-click the zip and choose Extract All.

  2. Open chrome://extensions in Chrome's address bar

    ① Open a new tab (⌘T, or Ctrl+T on Windows) and paste it into the address bar (⌘V or Ctrl+V), then ② press Enter.

    Chrome doesn't let websites open this address directly, so you copy and paste it.

    On a MacBook screen, chrome://extensions typed into a new tab's address bar, with the Extensions suggestion below
  3. Turn on Developer mode in the top right

    chrome://extensions
    The chrome://extensions page, with the Developer mode switch in the top right
  4. Click Load unpacked and select the unzipped handlus-extension folder

    chrome://extensions
    The Load unpacked button, which appears in the top left once Developer mode is on

    Or ① drag the handlus-extension folder onto this page and ② drop it

    On a MacBook screen, dragging the handlus-extension folder onto the Extensions page with Developer mode on shows Drop to install

    With Developer mode on, you see Drop to install. Let go and it installs right away.

  5. When you see the Handlus card, it's installed

    chrome://extensions
    The Handlus card in the extensions list

    Right after it installs, the Handlus setup page opens in a new tab. You'll use it in the next step.

A file install does not update itself. Keep it current with one command or the Handlus Updater.

Use several Chromes

  1. Install the extension in every Chrome profile you want the agent to use. Each profile keeps its own copy.
  2. Each install opens a welcome page. Connect it there with your Handlus sign-in email, Google, or a connection key, and give it a name.
  3. Your agent picks a Chrome by that name. How many Chromes get tools depends on your plan: see pricing.

Then connect your agent

Connecting a Chrome and adding the MCP server to your agent needs a Handlus account. The Free plan is enough to start.
