Site Spy

Site Spy hooks Claude up to website monitoring capabilities so you can track changes across pages without manual checking. The server lets you set up watches on specific URLs and get notified when content shifts, whether you're tracking competitor pricing, documentation updates, or availability changes. You'd reach for this when you need persistent monitoring as part of a workflow, like building alerts for product launches or keeping tabs on regulatory pages. The stdio transport means it runs locally alongside Claude, keeping your monitoring tasks in the same context as your other work.
