Connects Claude to the uurl.at URL bundling service, letting you create short links that redirect to multiple destinations in sequence or based on rules. You can generate QR codes for bundled links, check access counters to see how many times a link has been clicked, and look up where shortened URLs actually redirect. Useful when you need to programmatically manage link campaigns, track engagement through counters, or verify redirect chains without manually clicking through. The service is free and runs over streamable HTTP transport.
