api record

Project Gutenberg MCP server. No API key required. Typical workflow: gutenberg_search_books → gutenberg_get_book → gutenberg_get_text. Use gutenberg_browse_popular for discovery. gutenberg_get_text supports offset/limit chunking for long works — novels routinely exceed 500KB. Only books with has_plain_text=true can be read with gutenberg_get_text.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • gutenberg_search_books unknown never probed

    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.

  • gutenberg_get_book unknown never probed

    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.

  • gutenberg_get_text unknown never probed

    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 for reliable pagination. Prefers UTF-8 plain text; falls back to an HTML edition converted to text; refuses audio books (media_type "Sound") with a clear error.

  • gutenberg_browse_popular unknown never probed

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
