# Bowerjack

> Bowerjack Studio makes custom printable playing-card decks. It researches subjects for a theme, finds pictures from Wikimedia Commons, Flickr, Openverse and museum collections, checks each picture's license for how the cards will be used, and lays the subjects out as cards in a vector editor, where the deck is styled and refined. The deck is then downloaded, prepared for how it will be printed: print-ready files for MakePlayingCards, DriveThruCards, or The Game Crafter, including a custom tuck box, to order printed decks from them (usually about $35-$45 shipped, taking about a month); or PDFs to print at home, with a Cricut Print Then Cut outline to cut the cards. Bowerjack prepares files only; it does not print, ship or take orders.

Studio: https://studio.bowerjack.com/ (sign-in is an email address and a 6-digit code emailed to it; Bowerjack is in beta, so a new account needs an invite code, and a reset may delete every deck, accounts kept).

MCP connector URL: https://studio.bowerjack.com/mcp (MCP protocol version 2026-07-28, Streamable HTTP, OAuth). Sign-in happens in a popup on the first tool call; listing the tools needs none. Claude adds it as a custom connector.

ChatGPT: in the ChatGPT desktop app, open https://studio.bowerjack.com/ in its built-in browser and sign in. The Studio page registers its tools with the browser (WebMCP), and ChatGPT uses them there.

Workflow for an agent: a deck is one VectorCraft document, one artboard per card, kept as versions, worked on as JSON files cut from it (deck.json, layers.json, cards/<card>.json, symbols, swatches, styles, variables). studio_deck lists, creates and reads decks; studio_files views, edits, queries and patches the files and renders a card or every card; studio_content edits the deck's subjects and their pictures, adds pictures from verified records, finds printable Commons pictures and queues research; studio_generate makes a card's picture from the deck's own pictures. The user watches and edits the same deck in Studio, picks the art in Art Selection, and downloads it there. The server's instructions and tool descriptions name the tools and their order.
