## Exfil surface

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

| 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__bettyapp__get_lecture` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__bettyapp__get_lecture` |

## Findings

No check matched anything in these tool definitions.


## Only reads (4)

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

### `get_lecture`

- The name "get_lecture" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
One lecture on Bettyapp, by its id (lecture.id in a moment) or the address of its page: its course, teacher, Subjects and Levels, credit line, and every moment in it, in order, each with its play_url. Use it to give a student more of a lecture a moment came from, or to read a Bettyapp lecture link the student sent.
```

### `get_topic`

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

Description, as the server wrote it:

```untrusted-server-text
A topic (photosynthesis, chain rule, supply and demand): the best moment on Bettyapp that explains it at each Level, from school to university, then a few more and related topics. Use it to give a student an explanation at their level, or an easier or a harder one. If Bettyapp has no page for the topic, try search_moments.
```

### `list_subjects`

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

Description, as the server wrote it:

```untrusted-server-text
Every Subject with lectures on Bettyapp, each with its Levels and how many lectures it has, and the Level ladder from Elementary to Graduate & Professional. Use it to find the subject and level values for search_moments, or to tell a student what Bettyapp covers.
```

### `search_moments`

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

Description, as the server wrote it:

```untrusted-server-text
Find the moments in Bettyapp's university and school lectures that explain a topic or answer a student's question. Use it when a student asks about a topic, or is stuck on a question, and a short part of a real lecture would help. Each moment has a play_url that opens the lecture at that moment: give the student the best one or two, with the lecture title, teacher and credit line. The moments come best first. If none come back, Bettyapp has no lecture on it: do not say that it has.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__bettyapp__search_moments",
      "mcp__bettyapp__get_topic",
      "mcp__bettyapp__list_subjects"
    ],
    "ask": [
      "mcp__bettyapp__get_lecture"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__bettyapp__get_lecture`: untrusted-input, outbound
