Find personalized puzzle books by first name from a 100,000+ title Shopify catalog.
Connect On to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Find personalized puzzle books by first name from a 100,000+ title Shopify catalog. The on mcp server is what makes that connection.
Add this server to any MCP-compatible AI agent (Claude Desktop, opencode, etc.) and your agent will be able to search for books by the recipient's first name and hand the buyer a direct Shopify purchase link.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
search_books — Search the 100k+ personalized catalog by first name. Returns up to 9 matching books (mazes, name-sudokus, word searches across 3 difficulty levels)suggest_names — Suggest popular first names for which books are available, optionally filtered by a prefix. Use when a buyer is unsure of a spelling or wantsget_book — Re-resolve a single book's Shopify purchase URL from its product handle (as returned by search_books)Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
This sits in the payments and commerce group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. On's toolset — search_books, suggest_names, get_book — is a fair guide to whether it matches your workflow. It is maintained by gmlewis; worth a glance at recent repository activity before you build anything load-bearing on it.
