## MCP tools (4)

### `find_free_textbook` (~202 tokens)

Find a free textbook

Search for free and legal copies of a textbook on OpenStax, the Directory of Open Access Books (DOAB) and Open Library. Inputs: query (a book title, an ISBN or a course topic such as "organic chemistry") and an optional limit of 1 to 10 results from each source. Open Library results are marked free when there is a public domain copy to read online, and borrow when the book is a free loan. No account or key is needed. If one source is down the others still answer and the reply names the source that did not. Example prompt: "Is there a free legal copy of the Calculus textbook by Stewart, or something close to it?"

Input parameters:

- `limit` (integer): How many results to return, 1 to 10. Defaults to 5.
- `query` (string, required): A textbook title, an ISBN (10 or 13 digits, hyphens allowed) or a course topic.

Output parameters:

- `isbn` (string): The ISBN that was searched, when the query was an ISBN.
- `query` (string): The search text that was used.
- `results` (array): Free and borrowable books, OpenStax first, then DOAB, then Open Library.
- `sources_unavailable` (array): Names of the sources that did not answer, so a short list can be told from a failed search.

### `lookup_isbn` (~148 tokens)

Look up an ISBN

Look up an ISBN on Open Library and return the edition details plus the other editions of the same book. Inputs: isbn (10 or 13 digits, hyphens allowed). The check digit is tested first, so a typo is reported before any search. The reply has the title, authors, publisher, publish date, page count and edition name, and says whether a free copy is known. Related editions are listed newest first. Example prompt: "Look up ISBN 978-0-13-468599-1 and tell me what other editions exist."

Input parameters:

- `isbn` (string, required): The ISBN to look up, 10 or 13 digits, hyphens and spaces allowed.

Output parameters:

- `authors` (array): Authors, when Open Library lists them.
- `edition_name` (string): Edition name such as "3rd edition", when known.
- `free_copy` (boolean): True when a free copy to read online is known.
- `free_copy_url` (string): Where to read the free copy, when there is one.
- `isbn` (string): The ISBN as given, with hyphens and spaces removed.
- `isbn13` (string): The ISBN 13 form of the ISBN.
- `pages` (number): Number of pages, when known.
- `publish_date` (string): Publish date as Open Library gives it.
- `publishers` (array): Publishers of the edition.
- `related_editions` (array): Other editions of the same book, newest first.
- `title` (string): Title of the edition.
- `url` (string): The Open Library page for this edition.

### `list_open_textbooks_by_subject` (~165 tokens)

Browse open textbooks by subject

Browse free textbooks for a course topic. It lists matching OpenStax books and open access books from the Directory of Open Access Books (DOAB). Inputs: subject (a course topic such as "calculus", "nursing" or "economics") and an optional limit of 1 to 25 results. OpenStax books come first. If DOAB is down the OpenStax list still comes back and the reply says so. Example prompt: "List free textbooks for intro statistics."

Input parameters:

- `limit` (integer): How many results to return, 1 to 25. Defaults to 10.
- `subject` (string, required): A course topic or subject, like "calculus", "statistics", "nursing" or "economics".

Output parameters:

- `results` (array): Free textbooks for the subject, OpenStax first and then DOAB.
- `sources_unavailable` (array): Names of the sources that did not answer, so a short list can be told from a failed search.
- `subject` (string): The subject that was searched.

### `find_older_edition` (~230 tokens)

Find a cheaper older edition

Suggest earlier editions of a textbook, which usually cost less used than the newest one. Inputs: query (a title or an ISBN) and two optional values: edition_year, the year of the edition your course asks for, and limit, 1 to 10 suggestions. Without edition_year the newest edition Open Library lists counts as the current one, and an ISBN counts as the current edition when you pass one. Suggestions run from the closest older edition down. Editions only one or two releases back often keep the same chapters, but problem sets get reordered, so check the table of contents against your syllabus. The tool does not know prices. Example prompt: "My course wants the 9th edition of Stewart Calculus. Is there an older edition that would work?"

Input parameters:

- `edition_year` (integer): Year of the edition your course requires. Leave it out to treat the newest edition found as the current one.
- `limit` (integer): How many results to return, 1 to 10. Defaults to 5.
- `query` (string, required): The textbook title or its ISBN.

Output parameters:

- `current_year` (number): Year of the edition the suggestions are older than.
- `newest_year` (number): Year of the newest edition Open Library lists.
- `suggestions` (array): Older editions, closest to the current one first.
- `work_title` (string): Title of the book the editions belong to.
