What this server can do

4 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

gutenberg_browse_popular(limit, topic, languages)
Browse the most-downloaded Project Gutenberg books, ordered by popularity. Returns up to 32 titles with their Gutenberg IDs, authors, languages, and download counts. Optionally filter by language or topic. Use this as a discovery entry point — "what are the most popular classics in French?" — or as a heartbeat check that the catalog is reachable.
gutenberg_get_book(id)
Fetch complete metadata for a Project Gutenberg book by ID — title, authors (with birth/death years), translators, editors, subjects, bookshelves, languages, copyright status, and the full formats map with download URLs for each available format (plain text, HTML, EPUB, cover image, etc.). Use this before gutenberg_get_text to confirm a plain-text format is available and to get the direct download URL. Required: id.
gutenberg_get_text(id, limit, offset)
Retrieve the plain-text content of a Project Gutenberg book, stripped of the standard license header and footer so the response contains only the literary work. For long works — novels routinely run 500KB–2MB — use offset and limit to read in chunks rather than fetching the whole book at once. The response reports totalChars and remainingChars so the caller can page through without guessing. Prefers UTF-8 plain text; falls back to an HTML edition converted to text; refuses audio books (media_type "Sound") with a clear error. Required: id.
gutenberg_search_books(ids, page, sort, query, topic, languages, author_year_end, author_year_start)
Search the Project Gutenberg catalog of 78,000+ public-domain books. Matches title and author name with query words; filters by topic (subject or bookshelf keyword), language, author lifespan, or a specific list of Gutenberg IDs. Results are ordered by popularity (download count) by default. Returns book ID, title, authors, languages, subjects, and download count — use gutenberg_get_book for the full formats map before fetching text.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

Signal Value What it measures Window Observed Source
GitHub stars 2 Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality. cumulative, all time GitHub
Last commit 2026-07-11 Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained. point in time GitHub
Open issues 5 Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one. as of fetch GitHub
Latest published version 0.1.6 Latest version string the maintainer published to the registry. as of fetch Model Context Protocol
Registry record last updated 2026-07-11 When the registry record was last updated by its maintainer. point in time Model Context Protocol
License Apache-2.0 Licence GitHub detected in the repository. Detection can be wrong; the LICENSE file is authoritative. as of fetch GitHub

repository status active The repository exists on GitHub and is not archived. This says nothing about how recently it was worked on. as of fetch GitHub

Where to get it

Related, by what their authors tagged them

These share tags the maintainers applied themselves, such as books, bun, ebooks, public-domain. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
