## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `gutenberg_browse_popular`

- The name "gutenberg_browse_popular" says "browse": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Browse Project Gutenberg books ordered by downloads in the last 30 days at the source snapshot. Returns up to 32 titles with IDs, authors, languages, download counts, and is_readable. Filter by language, topic, MIME prefix or copyright status. Empty matches succeed with criteria and a notice; truncated results include executable search continuation. Use this for discovery — "what are the most popular classics in French?".
```

### `gutenberg_get_book`

- The name "gutenberg_get_book" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch complete metadata for a Project Gutenberg book by ID — title, authors (with birth/death years), translators, editors, source bibliographic notes, subjects, bookshelves, languages, copyright status, and the full formats map with download URLs (plain text, HTML, EPUB, cover image, etc.). Use is_readable before gutenberg_get_text; source_notes may identify specific editions.
```

### `gutenberg_get_text`

- The name "gutenberg_get_text" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_search_books`

- The name "gutenberg_search_books" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the Project Gutenberg catalog of 78,000+ books. Every query word matches a title or author substring; filter by topic, language, author lifespan, IDs, MIME prefix or copyright status. More than four query words require the local mirror. Empty matches succeed with criteria and a notice. Default popularity uses downloads in the last 30 days at the source snapshot. Returns IDs, titles, authors, languages, subjects, counts, and is_readable — use gutenberg_get_book for full metadata.
```
