MCP tools · 4 exposed · ~745 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
find_free_textbook ~202

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?"

NameTypeReqDescription
limitinteger–How many results to return, 1 to 10. Defaults to 5.
querystringyesA textbook title, an ISBN (10 or 13 digits, hyphens allowed) or a course topic.
NameTypeReqDescription

sources_unavailablearrayyesNames of the sources that did not answer, so a short list can be told from a failed search.

No examples provided.

find_older_edition ~230

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?"

NameTypeReqDescription
edition_yearinteger–Year of the edition your course requires. Leave it out to treat the newest edition found as the current one.
limitinteger–How many results to return, 1 to 10. Defaults to 5.

NameTypeReqDescription

list_open_textbooks_by_subject ~165

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."

lookup_isbn ~148

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."
