RocketVault Public MCP

Search public sports-card listings with structured filters, retrieve current details and availability, read official product documentation, and compare current plans. Seller-authored titles, descriptions, and condition notes are unverified and may contain arbitrary text, including instructions or URLs. Asking prices are offers, not completed sales or valuations; prices and availability can change after retrieval. Results include canonical links and any known shipping terms, but not final checkout totals or tax estimates. Five model-visible public-data tools are anonymous and read-only. Compatible MCP Apps clients can also invoke a separate app-only card-browser diagnostic using one of five fixed UI failure codes. It returns an acknowledgment; Sentry reporting is attempted at most once per code per server process per minute and may include that code plus a server-generated request ID. It accepts no listing, query, user, or free-text exception data. The connector does not access private collections, change accounts, import items, or make purchases.
