OpenCode Browse

OpenCode Browse is made by Anomaly and pairs an MCP server with a Chromium extension so agents can work inside the browser you already use. Agents open and drive tabs with Playwright, take screenshots, record the screen and capture network traffic, while you keep your existing logins and extensions.

What It Is

Browse is a browser-control tool for AI agents. Instead of launching a separate clean browser, agents operate in your real Chromium-based browser, so sites you are already signed into are available without API keys or extra setup. It works with any MCP client; the product page names OpenCode, Claude Code, Cursor, Codex and Zed among them.

How the Workflow Works

Agent tabs open in the background in collapsed tab groups so they stay out of your way. When a step needs you, such as a login, a 2FA prompt or a payment, the agent hands the tab back, and it continues once you click Continue. You can also lend an agent a tab you already have open by clicking the toolbar button. Outputs include screenshots, screen recordings and network traffic exported as a HAR file. Allowlists let you restrict a session's tabs to the sites you name.

Setup Path

Install the Chrome extension first; it walks you through the remaining steps. The CLI can also be installed directly via curl, PowerShell, npm or bun, though the page says this should not normally be needed. Supported browsers listed are Chrome, Edge, Brave, Arc, Helium, Vivaldi, Opera and Chromium.
