- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 556 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 4 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 556 tokens to load them all

## Tools (4)

- `create_checkout`: Open a checkout for online access to a book (or the whole library) for a reader, tied to their email. Returns a payment link to give to the reader; nothing is charged until they pay. After paying, the reader signs in on the site with that email and the book is theirs.
- `list_books`: The books, their languages, chapters (free, open opening, or paid) and prices of online access in each currency.
- `read`: Read any page of the site as markdown: an answer, essay, experiment, book page or chapter. Paid chapters give their open opening and how to buy the book.
- `search`: Search Neural Cosmology: answers to questions about consciousness, cosmology, physics and biology; essays; interactive experiments; books and their chapters. Returns titles, URLs and markdown URLs to pass to read.
