list_coupons
shallowcom.openshopgraph/mcp · Verify this server
List currently visible discount codes/coupons, optionally filtered by shop_domain (e.g. "otto.de"). Only publicly displayable coupons are returned — internal/candidate-shop or policy-suppressed codes are excluded, and EXPIRED codes are never returned (a code whose valid_until has passed is withheld). Each result carries validUntil: an ISO timestamp when the code has a stated expiry, or null when it is open-ended — null means unlimited, NOT unknown-and-expired. Re-check validUntil against the current time before relaying a code; including the shop domain and the expiry avoids sending users to codes that will not apply for them.
