Claude Desktop and Claude Cowork both run inside the same Claude app. A single BrowserClaw extension gives them both a real browser to work in.

​
Install

1

Install BrowserClaw

Download BrowserClaw from browseros.com/agents if you haven’t already. Launch it at least once so the local server is running.
2

Download the BrowserClaw extension

Head to the releases page and grab the latest browserclaw-<version>.mcpb file. This is the Claude Desktop extension package.
3

Drag it onto Claude Desktop

Open Claude Desktop’s Settings window and drag the .mcpb file onto it. Claude Desktop registers the extension and starts using BrowserClaw’s tools right away.

​
Verify

Open BrowserClaw, then in Claude Desktop ask:
Claude opens the page inside BrowserClaw and replies with the title.

​
Cowork gets it too

Cowork runs inside Claude Desktop, so the same extension unlocks it there as well. Ask Cowork to do a task that involves the web, and it uses BrowserClaw the same way Claude Desktop does. No second install.

​
Where the extension came from

The extension is a small forwarding wrapper: Claude Desktop talks to it locally, and it forwards every call to BrowserClaw’s local endpoint. Nothing goes to a server we control. Source, install file, and privacy policy live in the browserclaw-claude-desktop repo.

​
Troubleshooting

Claude says “BrowserClaw is not running”. Open BrowserClaw. The local server starts with the app. The extension does not load. Restart Claude Desktop. If it still fails, remove the extension from Settings and install the latest release again. Claude is not using BrowserClaw when it should. Say “Use BrowserClaw for this” the first time and Claude picks up the tools.
