A workspace's own URL offers only its companies. The Claude and Cursor install links use **All companies**. For one workspace, add its URL by hand.

Connect again at `https://app.bonnard.ai/mcp` and select another, or ask a workspace admin to invite you. ### `Staging addresses were retired. Connect to instead.` Use the URL in the message. ### `This connection request has already been used or has expired.` If you approved it, return to the AI client.
