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

## Findings

- **warn** Annotations that disagree with the tool in `build_maker_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "build_maker_link" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "build_maker_link" says "link": a word for a change.
```

- **warn** Annotations that disagree with the tool in `make_set_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "make_set_link" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "make_set_link" says "set": a word for a change.
```


## Changes things (2)

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

### `build_maker_link`

- The name "build_maker_link" says "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
A checked link that opens an Animal Math worksheet maker set up with the given settings, the settings in words, and anything it could not use. Also gives the maker's set item, to put it in a set with make_set_link.
```

### `make_set_link`

- The name "make_set_link" says "set": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
One short link (animalmath.com/s/<code>) to a set of Animal Math resources: printables (or some of their pages), makers set up, quizzes at a level, tools and whole curriculum lessons, split into days if wanted. The set page shows them all and makes one PDF of the printables. Checked here: items not found come back with a suggestion, and the short link is made once every item is found. Give the teacher the short link.
```

## Only reads (4)

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

### `get_curriculum`

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

Description, as the server wrote it:

```untrusted-server-text
Animal Math's free full-year math curricula, kindergarten to 5th grade. Without a grade: the list. With a grade: its units and lessons by number (every lesson has a lesson plan, an exit ticket and practice). With a unit too: that unit's lessons in detail and its pre-check, review and test.
```

### `get_lesson`

- The name "get_lesson" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "ticket": it reads issues, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
What one curriculum lesson uses: its goal, its lesson plan page, and the worksheets, maker settings, tool, quiz and exit ticket its plan names, each with its link. To give a teacher the whole lesson in one link, pass its set item to make_set_link.
```

### `get_maker_settings`

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

Description, as the server wrote it:

```untrusted-server-text
Every setting of one Animal Math worksheet maker, with its values and default, for build_maker_link. A maker draws new worksheets every time (find makers with search_resources, kind maker).
```

### `search_resources`

- The name "search_resources" says "search": a word for reading.
- Tag untrusted-input: The description's first sentence says "search" and "ticket": it reads issues, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Search Animal Math's free printables (worksheet packs, unit tests, exit tickets, lesson plans), worksheet makers, quizzes and teaching tools for Pre-K to 5th grade by topic words, grade, kind or a standard code. Each result has its page link and its set item for make_set_link; quizzes list their levels. Use it before giving any Animal Math link.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `animal-math`:

```json
{
  "permissions": {
    "allow": [
      "mcp__animal-math__search_resources",
      "mcp__animal-math__get_maker_settings",
      "mcp__animal-math__get_curriculum",
      "mcp__animal-math__get_lesson"
    ],
    "ask": [
      "mcp__animal-math__build_maker_link",
      "mcp__animal-math__make_set_link"
    ],
    "deny": []
  }
}
```

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

- `mcp__animal-math__search_resources`: untrusted-input
- `mcp__animal-math__get_lesson`: untrusted-input
