## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__books__search_books` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** Long descriptions in `search_books` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,796 characters long, over the 2,000 this check looks for.

description ends: "...isting turns up with everything the query asks for. A search takes a few seconds."
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_alert`

- The name "cancel_alert" says "cancel": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Cancel one of the person's alerts on Near Fine by its id, from list_alerts or set_alert, deleting it as its Delete button on Near Fine does. The first time, they sign in. Returns the cancelled alert and the person's plan.
```

## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `set_alert`

- The name "set_alert" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Set an alert on a search for the person. The first time, they sign in to Near Fine. Near Fine checks the alert for six months and emails them once when a new listing turns up with everything the query asks for, such as a first edition, a signed copy or a price cap. The query reads as search_books reads it. Listings there already never count: the alert stays pending until its first check has noted them. Setting an alert that's already set keeps it as it is. Returns the alert, with its status and its link on Near Fine, and the person's plan: how many alerts it allows, how many are in use and how often each is checked. A full plan comes back as an error; paid plans, at plans_url, have more.
```

## Only reads (3)

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

### `list_alerts`

- The name "list_alerts" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the person's alerts on Near Fine. The first time, they sign in. Finds come first, then alerts being checked, then the rest, newest first. Each has its id, query, country, status, when it was set, last checked and runs until, a link to it on Near Fine, and, once it has found a listing, the listing's title, seller, condition, price and shipping in the person's currency, and the URL to buy it. Statuses: pending (noting what's listed already), live (watching), found (emailed a find and stopped), ended (the person got the book), expired (ran its six months) and paused (the plan has room for fewer alerts). Also returns the person's plan.
```

### `list_sources`

- The name "list_sources" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the bookseller catalogs Near Fine searches, each with the countries it serves. Pass a country to see only the sources that serve buyers there.
```

### `search_books`

- The name "search_books" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Search for a book across every bookseller Near Fine covers for the buyer's country (AbeBooks and eBay sites everywhere, plus World of Books, ThriftBooks, Casa del Libro, Hugendubel, Booklooker, Leslibraires.fr, Rarewaves, Ex Libris, Librairie Mollat, Boekwinkeltjes.nl, Standaard Boekhandel, Managementboek, Dubray Books, Malliaris-Paideia, Indigo, Kinokuniya, Daunt Books, Paper Cavalier, Lets Buy Books, Chapters Bookstore, Harry Hartog, Book Grocer, Whitcoulls, Bokkilden, Bog & idé, Suomalainen Kirjakauppa, Booky.fi, Bookbot, Świat Książki, Matras, Luxor, Kosmas, IBS, Libraccio, Libreria Universitaria, Agapea, Label Emmaüs, Gandhi, Porrúa, Livraria da Travessa, Martins Fontes, Librería de la U, Ibero Librerías, Contrapunto, Maruzen Junkudo, BookOff, Kyobo, Yes24, Book Outlet, Livrenpoche, Buybook, Exclusive Books, Readers Warehouse, Wordsworth Books, Graffiti Books, Popular, MPH, BookXcess, National Book Store, Bookazine, Atlantic Books, Kitabay, Liberty Books, Tecni-Ciencia, Librairie Club, Books Upstairs, Nexus, Czytam.pl, Americanas, Livrarias Curitiba, Kel Ediciones and SBS Librerías where they ship, and Apple Books ebooks and audiobooks; shops' ebooks and audiobook downloads only in their own country). Pass an ISBN-10 or ISBN-13 for an exact edition, or title and author keywords. The query can also carry a price cap, as in "under $40" or "max 30 €" (in the buyer's currency when it names none), and ask for a first edition, a signed copy, a dust jacket, a hardcover or a paperback, as in "wolf hall signed first edition under £200", or for an ebook or audiobook alone. Offers over the cap, counting known shipping, and offers in other formats than the one asked for are left out; criteria reports what was read. Returns offers sorted cheapest first, each with title, seller, condition (new, used, ebook or audiobook), price and shipping in the seller's currency, the same in the buyer's currency when it differs, and the URL to buy. Shipping is left out where the shop doesn't publish it. Each offer may carry a match from 0 to 1: how sure a decision model is that the listing is the book searched for rather than a study guide, summary, adaptation or another book that shares a word. Below about 0.2 it rarely is. When the query asks for attributes, each offer carries verdicts: true where the decision model, reading the listing and any filter the bookseller applied, confirms the listing claims it, false where it doesn't, and left out where unjudged. Also reports which sources answered, failed or timed out, an amazon_url that opens the same search on the buyer's Amazon site, and a search_url that opens it on Near Fine, where the buyer can set an alert and get an email when a new listing turns up with everything the query asks for. A search takes a few seconds.
```
