Vicaro

Beta for macOS

An AI coworker that lives in your browser.

Vicaro opens tabs, reads pages, clicks and types in the Chrome you already use — or hands that same browser to Cursor, Claude Code and Codex.

What it does

A side panel that can actually use the web, not just talk about it.

Reads what you see

Every open tab, the page in front of you, and the text behind it — with the logins you already have.

Acts, then checks

Clicks, types, scrolls and navigates. After anything that changes the page, it verifies the result before answering.

Asks before damage

Purchases, deletes, sends and uploads stop for your Allow. Everything else runs without interrupting you.

Works with your tools

Registers as an MCP server for Cursor, Claude Code, Claude Desktop, Codex, Grok Build, VS Code, Windsurf and opencode.

How it works

The thinking runs on your machine. The browser is the interface.

  1. Install the helperA small menu-bar app. It holds the model connection and your history, locally.
  2. Add the extensionChrome side panel. You grant page access per site, the first time you use it.
  3. Point it at a modelA server on your LAN (Ollama, LM Studio, mlx, vLLM) or any OpenAI-compatible endpoint with your key.
  4. Ask, or hand it overType in the panel — or let Cursor and Claude Code drive the browser through MCP.

Install

macOS 13+ and Chrome 116+. Linux is next.

curl -fsSL https://vicaro.creativeducks.com/install.sh | sh

Installs the helper into ~/Applications and connects the AI tools already on your Mac. Add --no-mcp to skip the second part.

The installer also stages the extension and puts its folder on your clipboard. Then in Chrome:

  1. Open chrome://extensionsTurn on Developer mode, top right.
  2. Load unpackedCmd+Shift+G, paste the folder it copied, Return.
  3. Pin and openClick the Vicaro icon to open the side panel.

No Chrome Web Store listing yet — that is why this step is manual. The extension package is also there if you prefer to do it yourself.

No Developer ID yet, so the helper is ad-hoc signed — the installer says what it touches and how to undo it.

Questions

The short answers.

Does it send my pages to your servers?

No. Vicaro has no servers. Page text goes to the model endpoint you configure — locally, on your LAN, or a provider you already pay for — and nowhere else.

Is it open source?

No. Vicaro is closed-source software, and the helper is self-hosted: it runs on your machine and keeps its data in a local database you can inspect or delete.

Can I use it from Cursor or Claude Code?

Yes. Vicaro registers itself as an MCP server in the tools it finds, so they can list tabs, read pages, click and type with the same safety gate as the panel.

What does it cost?

Nothing while it is in beta. If that changes, the price will be announced before it applies — you will not be surprised by a bill.
