On-Demand-Books tools (3)

write = sends, deletes, buys or posts
  • get_bookFree

    Re-resolve a single book's purchase URL, cover image, and ISBN from its Shopify product handle. Use this to refresh or re-reference a book across turns without re-running the full name search.

  • search_booksFree

    Search for personalized puzzle books by first name. Returns matching books with direct Shopify purchase links, cover images, and ISBNs. A typical exact match returns 9 books across 3 puzzle types (mazes, name-sudokus, word searches) and 3 difficulty levels. When no exact match exists, returns similarly-named books. Use this whenever a user is shopping for a personalized gift and knows the recipient's first name.

  • suggest_namesFree

    Suggest first names for which personalized puzzle books are likely available. Use this when a user is unsure of a spelling, wants gift-recipient ideas, or only has part of a name. Returns popular available names, optionally filtered by a case-insensitive prefix. To confirm a specific name has matching books, follow up with `search_books`.

Agent calls search_books({ "name": "Susan" }) and replies:

Great news — there are 9 personalized puzzle books for Susan, including

"Fun Mazes for Susan — Easy to Medium" and "Fun Name Sudokus for Susan —

Implementation

This component uses the capability pattern from wasmcp, implementing just two methods from the tools-capability interface:

  • list_tools() — declares the three tools above.
  • call_tool() — dispatches to the right tool handler and returns the result.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
