Cali Elangdell MCP server

@pipeworx/cali-elangdell

CALI eLangdell Press's free, Creative Commons-licensed US law-school casebooks and course materials: 62 titles (torts, contracts, constitutional law, evidence, civil procedure, tax, legal research, property, criminal law …) with authors, topics, PDF/EPUB/Word download links on cali.org, and the exact licence read from each book's own front matter.

Part of Pipeworx — an MCP gateway connecting AI agents to 1576+ live data sources.

Tools

a topic word or a licence id/prefix; every response carries titlesbylicense so the licence mix is visible.

• elangdell_titles(topic?, license?, limit?) — the catalogue, filterable by

name or the description.

• elangdell_search(query, limit?) — titles by words in the title, an author

and the per-title licence as the license envelope.

• elangdell_book(slug) — one title in full: downloads, suggested attribution,

Keyless. The pack serves from a curated allowlist (src/titles.ts); it makes no upstream call. Downloads link to CALI's own files.

Licence — the allowlist is the compliance story

Licence varies per title, and the bookstore pages do not say which: the only statement is inside each book. src/titles.ts was generated on 2026-09-14 by reading the front matter of every title on (64 listed): the EPUB where there is one, else the PDF, else the Word file. Each row records the file the licence was read from and the book's own "Suggested attribution format" line.

Two of the 64 are deliberately not listed (NOTLISTED in titles.ts, with the reason): Civil Procedure: Pleading (2014), whose EPUB, PDF and Word files contain no Creative Commons statement at all, and CALI Lessons: A Guidebook…, which has no downloadable file. Where a file names more than one licence — cover-art and photo credits under other CC terms, or an EPUB metadata field left over from a prior edition — the row takes the licence in the book's own "This work … is licensed and published by CALI eLangdell Press under a Creative Commons …" sentence and says so in licenseresolution.

Two things the brief assumed that the books contradict: Sources of American Law is BY-NC-SA 4.0 in its current (8th) edition, not BY-SA; the six BY-SA titles are Torts: Cases and Contexts vols 1–2 (4.0), Distance Learning in Legal Education (4.0), and three Evidence titles by Colin Miller (3.0: Rule 404, Rule 410, Selected Materials on the Law of Evidence).

Consequences (fleet #1974, decision #1973):

the NonCommercial titles forbid charging. The BY-SA rows would not need it; requireszerorating on elangdell_book says which.

• zeroRated: true on the gateway entry — 0 credits on every tier — because

attachLicense in @pipeworx/shared; list responses carry the strictest terms any row has (BY-NC-SA), elangdell_book carries the title's own.

• Every response leads with attribution, license and license_note via

• Nothing is ingested: no book text is retained, only the catalogue rows.
