## 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__catalog__get_title` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `create_catalog_export`

- The name "create_catalog_export" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start an asynchronous export of every Vooks title matching the given filters, for bulk work that would otherwise be hundreds of searches. Returns a job id immediately; poll it with get_export_job. The idempotency_key makes a retry safe: calling again with the same key returns the original job rather than starting a second one.
```

### `recommend_titles`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Pick Vooks titles for one child, given their age, what they are interested in, how many minutes are available and which language to narrate in. Each recommendation comes back with the reason it was chosen, so you can explain the pick to a parent or teacher rather than just listing books.
```

## Only reads (5)

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

### `get_export_job`

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

Description, as the server wrote it:

```untrusted-server-text
Report the status of an export started by create_catalog_export. download_url points at the finished export. A job is derived from its id rather than stored, so it never expires and needs no polling: the status is succeeded the moment create_catalog_export returns.
```

### `get_pricing_plans`

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

Description, as the server wrote it:

```untrusted-server-text
Return every published Vooks subscription plan with its price, billing interval, audience and free-trial length, plus the school and district option, which is quoted per customer rather than priced. Use this to answer what Vooks costs instead of quoting a figure from memory.
```

### `get_title`

- The name "get_title" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Fetch a single Vooks title by its slug, including the publisher's full description, age band, Lexile measure, running time and topics. Reads the live catalog rather than the search index, so it is never a snapshot. Use it after search_titles when you need to say more about one book than the search result carries.
```

### `list_topics`

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

Description, as the server wrote it:

```untrusted-server-text
List every topic slug search_titles accepts, with how many titles carry each one. Call this before filtering by topic rather than guessing a slug: a guess that does not exist is rejected, and this tells you what the library is actually organised around.
```

### `search_titles`

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

Description, as the server wrote it:

```untrusted-server-text
Search the Vooks library of animated read-along storybooks, audiobooks and ebooks for children. Combine a free-text query with a child's age, a topic, a narration language and whether an audio-only version exists. Use this to answer 'what should a five-year-old who likes dinosaurs watch'. Returns the matching titles and the true total for the filters, so you can tell a narrow result from an empty library.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `catalog`:

```json
{
  "permissions": {
    "allow": [
      "mcp__catalog__search_titles",
      "mcp__catalog__get_title",
      "mcp__catalog__list_topics",
      "mcp__catalog__get_pricing_plans",
      "mcp__catalog__get_export_job"
    ],
    "ask": [
      "mcp__catalog__recommend_titles",
      "mcp__catalog__create_catalog_export"
    ],
    "deny": []
  }
}
```
