Report that the groupon-mcp server is running and its version. Deal-read tools arrive in a later phase.

Search or browse Groupon deals for a city (division). Pass query for a free-text search (e.g. "massage", "pizza"); omit it for a plain category/city browse. Set compact=true for slim deal summaries when browsing.

Fetch a single Groupon deal by its permalink slug (or full deal URL). Returns full detail by default; set compact=true for a slim view (title, subtitle, merchant, price, rating, division, option summaries, url).

Fetch Groupon's category taxonomy tree. Set compact=true for a slim {title, url, children} tree.

View the items currently in your signed-in Groupon cart. Requires a Groupon session (GROUPON_SESSION_COOKIE, or the fetchproxy browser bridge signed into groupon.com).

Add a Groupon deal option to your cart, ready for checkout. WITHOUT confirm:true this is a DRY RUN — it previews what would be added and makes NO change to your cart. WITH confirm:true it adds the item, re-reads the cart to verify, and returns the checkout URL for YOU to complete payment. It CANNOT place the order — Groupon checkout is native Apple/Google Pay, card, or PayPal.

Remove ALL items from your signed-in Groupon cart. WITHOUT confirm:true this is a DRY RUN listing what would be removed. WITH confirm:true it removes every line item and re-reads the cart to verify it is empty.
