Install the Xtaff Browser local host

The local host connects the Xtaff Browser extension to an AI assistant using MCP. The extension and host run on your computer. Your assistant may send data it receives to its configured model provider.

View @xtaff/browser-mcp on npm

Requires desktop Chrome 125+ and Node.js 22+. macOS has been tested; Linux and Windows have not yet been verified.

Setup

1. Install the Xtaff Browser extension from the Chrome Web Store.
2. Install and register the local host in a terminal:

   npm install --global @xtaff/browser-mcp
   xtaff-browser-host

   Run the second command again after moving or replacing Node, the global npm directory, or the package.
3. Configure your MCP client to run xtaff-browser-mcp. Find its absolute path using which xtaff-browser-mcp on macOS/Linux or where xtaff-browser-mcp on Windows.
4. Restart the MCP client. Ask it to use Xtaff Browser; approve the requested website in the extension popup. Tabs must be in the Xtaff group.

For Codex, add the following to ~/.codex/config.toml, replacing the path:

[mcp_servers.xtaff-browser]
command = "/absolute/path/to/xtaff-browser-mcp"
