Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

book
get_book
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.
books
search_books
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
suggest_names
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`.

On-Demand-Books — questions

Answers built from our own checks of this server.

What can On-Demand-Books do?
It exposes 3 tools, read directly from the server on our last check. Among them: get_book, search_books, suggest_names. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is On-Demand-Books working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 403 ms. The bar chart above shows every period we have measured.
How do I connect On-Demand-Books?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does On-Demand-Books need an API key?
No. On-Demand-Books completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is On-Demand-Books?
It answers our handshake in 403 ms on average, which is faster than 33% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is On-Demand-Books open source?
Yes — it is published under the Apache-2.0 licence, written in Rust and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
