OpenCode Browse is an MCP server and Chromium extension that lets coding agents control the user's real browser, including existing tabs, logins and extensions. Agents open and drive background tabs with Playwright, take screenshots, record the screen and capture HAR traffic, then hand the tab back for logins, 2FA or payments. It works with Chrome, Edge, Brave, Arc and other Chromium browsers, and with OpenCode plus other MCP clients such as Claude Code, Cursor, Codex and Zed.
OpenCode Browse pairs an MCP server with a Chromium extension so an agent can operate in the user's existing browser, using its tabs, sign-ins and extensions. It can open and drive background tabs with Playwright, take screenshots, record the screen and capture network traffic as a HAR. People can lend an open tab to an agent or take it back for steps such as login and two-factor authentication. The product supports multiple Chromium-family browsers and MCP clients, and offers session allowlists. Its code is available in the anomalyco/browse repository.
