Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| groupon_healthcheckA | Resolves the credential the way real tools do, then makes one authenticated request to www.groupon.com. Reports which source supplied the credential, whether www.groupon.com accepted it, the round-trip time, and a plain-English hint distinguishing 'no credential' from 'credential rejected' from 'a www.groupon.com-side problem'. Read-only; never returns the credential itself. Call this when a real tool fails and you want to know which hop broke. |
| groupon_search_dealsA | Search or browse Groupon deals for a city (division). Pass |
| groupon_get_dealA | Fetch a single Groupon deal by its permalink slug (or full deal URL). Returns the slim projection by default (title, subtitle, merchant, price, rating, division, url, and every option's id/title/price/isSoldOut — pass an option id to groupon_purchase); set view="full" for Groupon's whole record. |
| groupon_list_categoriesA | Fetch Groupon's category taxonomy tree. Returns a slim {title, url, children} tree by default; set view="full" for Groupon's whole payload. |
| groupon_view_cartA | 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). |
| groupon_purchaseA | Add a Groupon deal option to your cart, ready for checkout. Once confirmed it adds the item, re-reads the cart to verify the line quantity, 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. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). |
| groupon_clear_cartA | Remove ALL items from your signed-in Groupon cart. Once confirmed it removes every line item and re-reads the cart to verify it is empty. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). |

TDQS
Scored across 7 tools
Each tool targets a distinct resource and action: search vs. single-deal fetch, cart view vs. cart clear vs. purchase, taxonomy listing, and a diagnostic. The boundary between search_deals and list_categories is clarified by the descriptions (free-text/option browse vs. raw taxonomy tree), so an agent can select reliably.
All seven tools share the groupon_ prefix followed by a consistent verb_noun pattern (search_deals, get_deal, list_categories, purchase, clear_cart, view_cart, healthcheck). No mixed casing or divergent verb styles.
Seven tools is well-scoped for a deals/browsing-plus-cart server. Each tool earns its place (browse, detail, taxonomy, purchase, cart view/clear, health), with no redundant or filler entries.
Core lifecycle is covered: discovery (search/deal/categories), cart read (view_cart), cart write (purchase, clear_cart), and diagnostics. The main gap is granular cart editing—no remove-single-item or quantity-update—but clear-all plus re-add lets agents work around it.
